Things To Consider Before Starting A Fish Farm Business

Are you considering entering the fish farming business, and are you considering factors to consider when planning to locate your fish pond? Fish farming is one of the thousands of dollars of profitable business ideas during the harvest season. Fish feed pellet machine is the indispensable equipment to make fish feed pellets.

Have you gone into fish farming, but it doesn’t seem to be growing as expected? If so, please read and study this guide carefully as its promise to provide you with all the necessary factors to know before sitting on a fish farm.

Making Your Own Fish Feed

The fish feed extruder is used to make floating and sinking fish feed pellets.

Market

If you want to build a fish farm, the market is the first thing to consider. It also applies to almost all agricultural enterprises. If you want to make a profit and continue your business, you want to know who and where to sell your fish, unless you don’t consider selling your fish after harvest.

Location Of The Farm

The location of the fish farm is very important. The location may affect several other factors, such as the type of pond and water source. Choosing a location that suits the type of fish you intend to grow. You need to consider several other factors to find the right location for your fish farm. If you are considering digging out a pond, you will need a location with the right soil type and adequate water supply.

Where Can You Gather Knowledge

Once you find the right location for your business, you need to learn as much as you can about fish farming before you actually start investing in it. To learn about the fish industry, visit several fish farms in your area or find online resources. Visit some fish farms to find out the pros and cons of fish farming.

Do You Need A Business Plan

Before starting any business, you need to develop a business strategy. Your business plan should contain all necessary information about the company structure, expenses, expected investments, and expected return on investment. Take some time to consider all possible costs and make sure everything you need to do business in the plan is included. Determine what you need. How many employees, what equipment and supplies, your overhead, capital and assets.

Availability Of Water

No fish farming without water. So when you want to build a fish farm, quality water must be one of the main resources you look for. In addition, your fish farms and operations should not cause problems for other uses of water, especially if used by others.

The Choice Of Fish Type

You may also want to consider the fish type you want to keep. Depending on the preferences and recommendations of the experts, you can choose some of them. There are tilapia, catfish, tuna, salmon and so on.

Environmental Factors

The environment is very important because your farm may face potential dangers and threats, such as vandals, insects, birds, snakes, and cats. Environmental conditions may also be related to climatic conditions, such as rainfall and sunshine. Environmental conditions/hazards determine the habitat type for fish farming.

How Many Fish Feed Pellets to Feed Your Fish

Pellet making machine can make fish feed pellets. The number of fish feed pellets that an individual fish can catch is related to its swimming activity, which is, in turn, partially temperature-dependent. Zhengzhou Fusmar is a professional fish feed extruder manufacturer.

Rainbow trout could catch larger numbers of pellets in a single feed portion as temperatures increased from 5 to 15°C under laboratory conditions; this change is likely mediated by changes in the fish’s activity at different temperatures. The feeding rate of brown trout increased rapidly between 3.8 and 6.8°C, remaining relatively stable between 6.8 and 19.3°C, before decreasing at temperatures above 19.3°C. Changes in the feeding and swimming activity of salmonids at different temperatures have been presented by others with the greatest change in activity occurring between 5 and 10°C. In aquaculture, the feed delivery rate should therefore be taken into account when calculating a feeding regime.

The size of feed pellets and the rate at which they are delivered may affect the amount of feed an individual fish can ingest over a period of time. Pellets of sub-optimal size or pellets that are delivered at a high rate may cause wastage, as fish may be unable to catch large numbers of pellets before they sink through the net pen. Salmon farmers use many different sizes of feed pellets during the grow-out period, and each time the size is changed, new calculations for the optimal number of pellets per fish and delivery must be done. It would therefore save both time and money if fewer sizes of pelleted feed can be used for larger parts of the grow-out period.

At some extreme, pellet size will obviously have an effect on fish performance, and there are indications of this effect presented here. For example, a pellet that is larger than the gap width of the fish or is so large that handling time becomes a limiting factor in the fish’s ability to ingest enough pellets to maintain good growth will clearly have adverse effects. Adult salmon showed a more immediate response to larger pellets but that these were more likely to be rejected than pellets of a shorter length.

Pellets slightly smaller than the ‘‘normal’’ commercial size were eaten at the fastest rate, thereby indicating that the salmon are perhaps adjusting their feeding behavior to compensate for a smaller feed pellet size. For Arctic charr reared under hatchery conditions, the optimal pellet size has been suggested to be around 2% of the fish’s length. Others have suggested that for a range of fish species, the optimal feed size appears to be 25–50% of the mouth width. It appears that fish can adjust to reasonable deviations from the optimal pellet size with no significant negative effects on growth.

Extrusion Technology and Feed Production Process Control

Fish feed pellet machine, the main equipment is “screw extruder”. The main kinds are fish feed extruder, soybean/corn extruder, and feather extruder. Fish feed extruder is the common machine in the fish feed production line, which includes a single screw extruder and twin screw extruder.

Extrusion Process And Main Kinds Applied In Feed Production

The material is fed into the fish feed extruder and moves in the form of an axial flow under the screw power. At the same time, due to the mechanical friction between the screw and the material, the material and the barrel, and the material particles, the material is strongly squeezed, stirred, and sheared. As a result, the material is further refined and homogenized. With the gradual increase of pressure, the temperature rises accordingly. Under the condition of high temperature, high pressure, and high shear, the physical properties of the material have changed as follows:

From powder to paste.

2. Gelatinization of starch.

3. Protein denaturation.

4. Partial degradation and refinement of fiber.

5. Pathogenic bacteria were killed.

6. Health indicators are improved.

7. Toxic components were inactivated.

When the paste material extruded from the die hole, under the influence of strong pressure difference, the material is expanded, dehydrated, and cooled. The final product is of loose and porous structure, crisp, good palatability, and flavor.

Extrusion Process And Characteristics Of Extruded Products

Biochemical Process

The process of hydrothermal treatment is accompanied by the biochemical change process of the material. Some materials, such as oilseeds and their cakes, contain a variety of anti-nutrients and anti-feeding ingredients. Under certain moisture and certain temperature conditions, these active substances gradually lose their activity, weakening the destruction of digestive enzymes inside the digestive system of animals, which improves absorption rate and reduces excretion. This not only improves the nutrition value of feed, but also reduces waste and environmental pollution. From the view of the biochemical process, the extruder is a “biochemical reactor.”

2. High-temperature and short-term germicidal detoxification process

The highest temperature in the puffing process can reach(130-160) °C, while the material in the high-temperature segment is very short, about 5-10 seconds. High temperature can not only kill pathogens and health indications, but also can inactive a variety of harmful factors and enzymes, improving the feed quality.

3. Better chemical stability and longer quality guarantee period

High temperatures cause various microorganisms and parasitic ovum to be killed and various enzymes( such ad oxidase, lipase, etc.) are inactivated. That excludes a wide range of factors that contribute to the deterioration of the material.

4. Wide range of process adaptability

The extrusion process can not only improve the feeding quality of a variety of common feed materials, but also can process a large number of unconventional materials into high-quality feed materials, which include wild plants, agricultural by-product, slaughter waste and of livestock and poultry, etc. Fish feed extruder can produce a variety of different specifications and quality of livestock poultry materials, aquatic feed, pets feed, etc. At the same time, the extrusion process is also the most effective technique for the detoxification, preservation, and processing of grain cakes and deep processing of grain.

5. High-grade product features

Extrusion products are loose and crunchy after being cooled, composite products produced by various components, and Maillard reaction due to high temperature. All these factors constitute better palatability over the original mixture and have a special flavor. These characteristics induce animal feed to intake, thus increasing feed intake and feed effectiveness. This is completely different from the addition of phagostimulant to the mixture, which often has negative effects.

6. It can produce special feed with different shape

According to the user’s requirements, changing the model design can produce different shapes of large particles, large blocks or bar-like materials, such as prawn feed, pet feed, rare animal feed, etc. This is what the ring die pellet machine can’t do.

7. Higher digestion rate

For those suckling pigs whose digestive system is not well developed, the starch in the weaning material requires the gelatinization degree of more than 90%. And the aquatic animals also requires the gelatinization degree of the feed should also be higher because their absorption capacity of the original degree is poor. Extruder machine can realize it well.

Therefore, it is better to use extruder than ring die pellet machine to produce aquatic products because due to the temperature restriction, the gelatinization degree of starch processed by ring die pellet machine can not be high, which is generally no more than 50%.

Gelatinization not only improves digestibility, but also improves granulation and shaping because dextrins are good binders. The gelatinized starch molecules crosslink each other to form a network-like spatial structure, lose some moisture after being instantaneously expanded, and become a skeleton of the expanded product after cooling, so that the product maintains a certain shape.

How To Choose Floating Fish Feed Machine And Its Auxiliary Equipment

With the rapid development of aquaculture, its economic benefit has become considerable. Therefore, various aquatic feeds, in particular floating fish feed pellet, rise in response to this trend. Because aquatic animals like fish and shrimp have small intestines and stomach with bad digest absorption ability, the manufacturing process of aquaculture feed has much higher requirement than that of livestock feed. Which means it’s very important to choose suitable fish feed machine to produce aqua feed.

Before choosing fish feed production line machinery, it’s very necessary to learn about the features of aquatic feed:

Small particle size. Due to short intestines stomach and other physiological properties of aquatic animal, in order to accelerate digest and absorption, the fineness of pulverization of aquatic feed should be smaller than poultry feed. For example, when producing fish feed or prawn feed, the raw material flour size should reach 60-120 meshes which could make sure to make good quality of fish feed pellets.

With this reason, the feed hammer mill or feed grinding machine would be very important to make sure producing very fine flour material.

Recommend: Fusmar grinding machine. It has two kinds: small grinder machine and fine grinding machine. The final fineness is respectively 60-80 mesh and 80-200 mesh.

2. High protein content and low carbohydrate. The protein content of livestock feed is often less than 20%, while that of aquaculture feed is always 30%-40 or more. Especially for the small fish feed which is growing very fast, and some aqua feed protein content is up to 65%-70%.

With this, we should choose good feed formula, and using feed mixer machine to mix different materials together. It is one of the key equipment, of which the performance directly affects the production efficiency and product quality of feed plants.

Recommend: Economic Fish Feed Mixer Machine. It is widely used in the evenly mixing of fish feed raw material to ensure quality pellet making.

3. Pellet feed structure is compact. With higher cohesiveness and water resistance. For instance, aqua feed requires the water stability of pellet up to 2-10 hours or more.

Since fish feed production requires higher degree of gelatinization and water stability, the selection of fish feed extruder is very important. Through prolonging materials tempering time and starch gelatinization under high temperature can strengthen adhesive property of feed pellets, kill Salmonella and other various harmful bacteria. Which not only promotes the water stability of fish feed but also improves the palatability and digestibility of feed.

Recommend: Floating fish feed machine. It has two kinds: wet type and dry type. As for which one to choose, it is according to your need and your requirements.

Useful Guidance For Catfish Farming In Nigeria

Catfish farming is increasingly becoming an attractive form of agriculture for many Nigerians especially young people. This form of agriculture has found a huge followers-base primarily due to the relative ease of culturing catfish, the readily available markets for catfish, such as restaurants. Especially as catfish is a treasured delicacy among many Nigerian cultures as well as the profitability of a successful catfish venture.

Zhengzhou Fusmar Machinery is a professional fish feed pellet machine manufacturer.

Why Catfish So Popular

The demand for Catfish in Nigeria is unprecedented so much that no matter the quantity supplied into the market is consumed by ready buyers. This is so because of its low caloric value, low carbohydrate content, high in protein, low in fat, it is quick and easy to prepare and above all, it tastes great.

Useful Guidance For Catfish Farming In Nigeria

Before venturing into catfish farming, it is pertinent to take a number of factors into consideration for success.

Quality of Fingerlings: Catfish fingerlings are of different breeds, just like other species of animals. It is important that the catfish farmer takes his time to identify fast-growing and disease resistant breeds of fingerlings to ensure profitability in a catfish venture. This can be done through appropriate consultation with a specialist in fingerlings and physically evaluating fingerlings from several farms before making a pick on the stock of fingerlings.

Pond Design: Stocking density plays a huge role in the growth rate of cultured catfish. Like for all other animals over-crowding catfish would increase competition for resources like food and oxygen. This can promote the growth of some fish at the expense of others and in the end lead to cannibalism. Therefore the catfish farmer would want to consider an appropriate length, breadth, and depth of the pond, depending on his intended number of fishes to the stock pond. Also pond design should incorporate provision for the separation of fishes in the event that growth is non-proportionate to avoid cannibalism. Water management for pond would mean periodic changing of water and pond design should incorporate this from the outset to avoid challenges.

Feeding Catfish: Feeding constitutes the bulk of the cost of rearing catfish. Through the development of fish farming over the years in Nigeria, feeding of catfish is predominantly done using pelleted floating feeds. This ensures adequate feeding of the fish thus increased growth rate and weight.

For fish pelleting machines, Fusmar fish feed extruder is your best choice. Zhengzhou Fusmar Machinery is one of the manufacturers and exporters of Fish Feed Machine and Turnkey Fish Food Production Line. For more information, please contact us.

Local Raw Materials For Fish Feed In Nigeria

For making more profits in aquaculture and fish farming business, Nigeria fish farmers need to cut down fish feed cost because it occupies a big part in the whole production chain. Today, let’s discuss the way for Nigerian to use local raw materials to make fish feed pellets for lowering feed cost.

The Significance Of Using Local Fish Feed Raw Material

As the fastest growing food production industry in the world, aquaculture, and fish farming industry in Nigeria also plays an important part in delivering high-quality proteins to the market, so lowering the feed cost – main cost factor in aquaculture has great significance and value in stimulating the development of aquaculture. Meanwhile, with high price and unstable supply, imported fish feed has always restricted the development of Nigeria fish farming. Furthermore, from the perspective of environment and economy, people should focus on using local feed ingredients to produce nutritional and healthy aquafeed through fish feed extruder and other equipment, reducing feed cost as well as creating an effective value chain and pull whole aquaculture industrial chain.

Available Local Fish Feed Raw Materials

Similar with other animals, fish also need protein, carbohydrate, lipids, minerals, and vitamins for healthy growth. The main ingredients of fish feed contain protein, fat and mineral substance. And raw materials of these ingredients mainly include straw meal, soybean cake, peanut cake, corn protein powder, rice bran, wheat bran and so forth. To be specific, based on the nutrient requirements of fish, here are some potential local resources that can be used in making fish feed:

Raw materials for protein: fish meal(with 62%-66% crude protein), blood meal, silkworm chrysalis meal, shrimp meal, soybean meal(with 45% crude protein), cottonseed meal(with 32%-42% crude protein), rapeseed meal(with 33%-40% crude protein), peanut meal, sesame meal and corn gluten meal, etc. Besides, earthworms, maggots, and insects are also high-quality animal protein feed for fish.
Raw materials for energy source: wheat, wheat middling, full cream rice bran, corn and other grain. Among these materials, corn has high carbohydrate that cannot be absorbed easily by fish or shrimp, so in general, corn content should be low when producing aqua feed. Wheat has soft texture as starch but wheat has excellent elongation and elasticity, which makes it natural adhesion agent that can promote water stability of fish feed for long-time floating on water. Full cream has high content of fat, adding about 6% as raw material can make it easy for pelletizing and save power consumption, but remember to pay attention to oxidative rancidity. Moderate addition of fat content can promote the digestive ability of feed, improve availability of protein so as to achieve the effect of saving feed protein.
Mineral substance (like calcium, phosphorus, iron, zinc and iodine) is an important component of fish feed, and plays a pivotal role in fish growth and nutrition. Common raw materials with minerals contain fish meal, shell powder, egg shell powder, calcium phosphate and bone meal.

Locally available raw materials such as yam, plantain, banana, cowpeas, macona, maize, cassava, millet, sorghum, groundnut, sunnhemp seed, leaf concentrates, kitchen garbage and brewery wastes are considered as potential materials for fish feed.

How To Produce Fish Feed With Local Raw Materials

With such abundant local resources, fish farmers may consider how to produce fish feed by themselves instead of purchasing feed so as to lower their farming cost and gain higher profits. First, choose scientific and nutritional aquafeed formulation. Second, master advanced feed processing technology. Third, choose suitable fish feed making machine.

When choosing fish feed formulation, there are several principles to follow: according to nutritient requirement of farmed fish and nutritional value of feed, because different fish has diverse varieties, ages, weights, habits, physiological conditions and even water quality environment, which makes them have different requirements for nutriment. According to palatability and digestibility of feedstuff (for example, blood meal has about 83% protein but only 19.3% protein is digestible while bone meal has only about 46% protein but its digestibility is 75%). According to the balance bewteen protein and amino acid in order to reach the requirements stipulated by nutritional standards. According to lowering materials cost on the basis of nutrients for maximum economic benefits.
As to aquafeed processing technique and equipment, Fusmar, a pioneer in the manufacturing field of fish feed machine and fish food production line, is able to offer the whole production processing of fish feed and the appropriate equipment – from materials crushing, mixing, extruding and drying cooling to final feed packaging. For instance, fish farmers can use fish feed hammer mill for grinding raw materials into very small granulars, use high-efficiency fish feed mixing machine to blend feed materials evenly for ensuring high quality compound feed, use fish feed extruder to make floating feed pellet and also adjust extrusion degree for floating time on water when extruding pellets, use fish feed dryer to decrease moisture of feed down to 8%-12% for convenient storage, and eventually use packing machine for automated weigh and package of finished fish feed pellets.

Why Choose Fish Feed Pellets To Feed Your Fish

Fish feed pellet machine is a feed processing machine that directly presses the crushed materials of soybean meal, bran, grass, fish meal, bean cake, barley, corn meal, and other materials into fish feed pellets.

Why Choose Fish Feed Pellets To Feed Your Fish

1. The fish pellet feed should not be stored for too long. If the storage time is too long, it will cause dehydration mildew and affect the use-value of the pellet feed. Feeding the spoiled fish pellet feed will make the fish susceptible to disease. Fusmar Machinery recommends that users best produce feed pellets while feeding.

2. When the total amount of bait is unchanged, the number of baits should be increased to reduce the amount of bait each time. So that the fish is always in a semi-hungry state, which can increase the bait utilization rate and reduce the bait coefficient.

3. Before using the pellet feed, a short period of domestication should be carried out to make the fish form a fixed food court and a fixed time of feeding habits. The bait should be evenly distributed every time, the feeding time should be no less than 30 minutes, and the feeding area is 40 ㎡ ~ 60 ㎡, so that every fish can eat bait.

4. The diameter of the fish pellet feed should be reasonable. When the fry is stocked, the water temperature is low, the growth is slow, and the size is small. It is more suitable to control the pellet size to 2 mm. As the temperature rises and the fry grows, the feed pellet size is 3 mm ~ 3.5 mm, the pellet size in the later stage of breeding is 4 mm to 4.5 mm.

5. Adding salt appropriately to prevent fish diseases. When using fish feed extruder to press the pellet feed for fish, Fusmar Machinery recommends that 1% of the table salt be evenly mixed into the raw materials, which can sterilize and prevent fish diseases.

6. Fertilize reasonably. Fish ponds fed with fish pellet feed should be properly fertilized to promote the growth and reproduction of plankton, increase the fish production.

The Advantages Of Fish Feed Pellets For Feeding Fish

A large amount of data has proved that the fish pellet feed made by fish feed production line machinery has comprehensive nutrition, strong stability. It is not easy to collapse in water and not easy to pollute the water body, and is easy to digest and absorb. Fully meet the growth needs of fish, so as to speed up the growth of fish.

Fusmar Machinery warmly reminds: Never use prohibited drugs in the safe fish feed pellets, otherwise the fish will not grow well. Which will affect the sale and benefit, and also affect people’s health.

Fish Feed Pellet Machine Can Produce All Kinds Of Fish Feed Pellets

Nowadays, the fish feed pellets, although specially produced for fish production, it is also a very good bait. As long as the rubber band is put on the feed pellet to fish. At present, fishing gear stores also sell rubber-coated pellets, which are very convenient to carry and use, and the effect is not bad.

Full-price compound pellet feed refers to a feed mixed with various substances for the growth of fish required. Fish feed pellet machine can produce all kinds of fish feed pellets.

Fish Feed Pellet Machine Can Produce All Kinds Of Fish Feed Pellets

There is also a very special name for the fish feed pellet, which called “full price compound pellet feed”, also known as a compound feed or pellet feed. Which refers to a feed mixed with various substances for the growth of fish required, such as plants, animal, oil, yeast, and other raw materials. Of course, if the raw materials used are different, the feed pellets will be very different. The pellets are formulated according to different fish species and different needs of the fish from small to large stages. The size of the pellets is also different. Feeding large fish with large pellets and feeding small fish with small pellets. All these are designed and produced for fish farming.

Different Pellet Making Machinery Can Produce Different Pellets

The pellet making machinery is different, and the pellets produced are also different. For example, the machine for making a soft feed pellet has a simple structure and no drying equipment. Therefore, the pellets produced have large water content and can not be stored for a long time. They can only be used as they are, these are mostly small-scale production.

The other fish feed extruder produces hard feed pellets that we often see. It has a variety of supporting equipment such as crushing, mixing, molding, and cooling drying, which can be mass-produced. Now there is a relatively new type of pellet feed processing equipment, which is a floating fish feed pellet machine. The raw material ejected from the die hole through high temperature and high pressure. Its moisture suddenly vaporizes, causing the pellet to expand instantly, the volume increases, and the specific gravity decreases. This floating pellet machine now not only produces feed for feeding fish, but some fishing bait manufacturers also produce puffed pellet fishing bait.

Some Suggestions On Catfish Feeding

Feeding is the most important task in the intensive pond production of catfish, in a normal situation, for catfish can be seen only when they are coming up to feed, and their feeding behavior can be an important clue to general health and to other conditions in the pond.

Zhengzhou Fusmar Machinery is a professional fish feed pellet machine manufacturer, if you need a fish feed production line, please contact us.

Feeding A Nutritionally Complete Diet

Catfish farmers are able to feed a nutritionally complete diet that provides required levels of nutrients and energy in a readily digestible form. It is essential to provide a complete diet because catfish can synthesize only a small portion of the required nutrients and the quantity of nutrients from natural food organisms in the pond is relatively small. Forty nutrients have been identified as necessary for the normal metabolic function of channel catfish.

Based on current knowledge, digestible energy to crude protein (DE/P) ratio of 8.5-10 kcal/gram is adequate for use in catfish feeds. Ratios above this range may lead to increased fat deposition and if the energy ratio is too low, the fish will grow slowly.

Catfish Feeds Energy Source

Catfish feeds contain grain or grain by-products that are rich in starch. In addition to providing an inexpensive energy source, starch helps bind feed ingredients together and increases the expansion of extruded fish feeds, so that the feed pellets are water stable and float in the water.

There are various types of catfish feeds. The type being used at any particular time is a function of size of fish being fed, whether the fish are feeding at the surface or in the water column, and if an antibiotic is incorporated.

How To Raise Catfish Fry

Catfish fry in hatcheries is fed finely ground meal or flour-type feeds containing 45-50 percent protein. Fines or crumbles from 28 or 32 percent protein feeds for food fish grow-out are suitable for fry stocked in nursery ponds until they reach 1-2 inches in length. Larger fingerlings should be fed small floating pellets (1/8 inch diameter) containing 35 percent protein. Advanced fingerlings (5-6 inches) and food fish are generally fed a floating feed of approximately 5/32 – 3/16 inch in diameter containing 28-32 percent protein. Some producers switch to a slow-sinking feed during the winter.

Antibiotics are administered to catfish through incorporation in feeds. Depending on the particular antibiotic chosen, the fish feed pellets made from a fish feed extruder may either be floating or sinking.

The feed is typically blown onto the surface of the water using mechanical feeders. Feeds should be scattered over as wide an area as possible to provide equal feeding opportunities for as many fish as possible. Feeding with prevailing winds allows the feed to float across the pond and minimizes the amount of feed washing ashore. Overfeeding should be avoided since wasted feed increases production costs.

Despite considerable research, feeding catfish is far from an exact science. It is a highly subjective process that differs among catfish farmers. Experience should be found gradually in the feeding process.

How to Process Chicken Manure into Fish Feed Pellets

Our company Fusmar manufactured fish feed pellet machine, welcome to visit our website and inquiry machine details. This article will introduce how to process chicken manure into fish feed pellets.

Why Make Fish Feed Pellets From Chicken Manure

The chicken manure contains sprinking chicken feed, dander, feather, a slight of broken eggs and undigested feed as well as unabsorbed nutrients. According to the research, crude protein accounts for 30~33% in the dry chicken manure, more than half of which is uric acid, so the chicken manure is the good feed for fish and the ideal material for making fish feed pellets.

Using chicken manure to make fish feed pellets can reduce the feeding cost and form a good ecological cycle between chicken and fish farming. While, the raw chicken manure is not suitable for feeding fish directly because of containing parasitic ovum, some toxic substance, and germs. Only after the treatment of professional leavening agent can the manure be non-toxic and nutrient-rich fish feed.

Fish Feed Making Process

1. Mix the chicken manure (accounts for about 50%) with proportional corn flour, bean cake, rape seed cake, and wheat bran.

2. Add a certain amount of leavening agent to the mixture (the leavening agent can be diluted with water in advance to be mixed easily and evenly with materials.)

3. Adjust the moisture content to be about 60 % ( a simple judging method: grasp the material firmly, and then it can clump; let it go and it can break up.)

4. Put the material into a plastic bag or pond which can be sealed. You can get better result to pour human and animal excreta on the fungus chaff.

5. Cover the mixture with plastic film to make it ferment for 3-7days (a little longer in winter)

6. When the chicken manure become yellow green and send out not stink but tartness like wine (the longer the fermentation, the stronger the winey smell), the fermentation is finished.

7. Put the fermented chicken manure into the fish feed extruder, then you can get nutrient-rich and uniform fish feed pellets.

The feed cost for every kilogram fish is only 0.15-0.20 yuan with this fish feed pellets, while it is 0.30-0.40 yuan with common feed pellets at present. So, feeding fish on this chicken manure feed pellet can reduce the feed cost by more than 50%.
