Good feed, generally there are soybean meal, fish meal, shrimp meal, beef heart, plus trace elements, etc., things to make

The best is the small fish, and the simplest food chain is that the big fish eat the small fish.

It is a kind of fish processed in the sea.

1) Plant green fodder. At present, the more common green fodder planted are ryegrass, Sudan grass, alfalfa, clover, etc., and the yield of grass per mu can reach 5 tons and 10 tons. There is great potential for growing green fodder fish farming.

2) Make the most of various by-products. Including agricultural and sideline products are adapted to areas with large water surface and abundant by-product resources. This kind of feed includes bran, rattan, seedlings, etc., which are crushed or processed into pellet feed; Industrial by-products such as brewer's grains, soy sauce residues, powder residues and non-staple food scraps such as vermicelli factories and starch factories are precipitated and dried after slurry protein powder.

3) Supporting the establishment of small feed mills. It is suitable for intensive aquaculture in fishing grounds with large water surface and high level of intensive culture. By planting green fodder and using by-product fish farming, we can make full use of the resource advantages to reduce the cost of farming.

2. What are the commonly used energy feeds for fish farming: energy feed accounts for 40%-50% of fish feed. Energy feed is mainly cereals such as corn, barley, wheat, rice, etc., and their processing by-products such as rice bran, bran, secondary flour, etc.

Energy feed generally has a high digestibility and can reach more than 50%. Lower than protein feed**. However, its nutrient content is single, mainly soluble sugars and starches, so it cannot be used as fish feed alone.

It is more suitable to use this type of feed to process fish feed. On the one hand, it provides energy, on the other hand, it can also be used as a binder for processing pellet feed, especially for the production of extruded pellet feed, which can increase the flavor and improve palatability.

3. What are the commonly used mineral feeds: The main role of mineral feed is to provide macromineral elements for fish. Mainly calcium, phosphorus, sodium, chlorine, etc.

The main types of mineral wheel feed used are as follows: (1) Bone mealBone meal provides phosphorus and calcium. Due to its different processing methods, it can be divided into three types: steamed bone meal, raw bone meal, and bone char powder.

Steamed bone meal is commonly used as feed. Due to processing problems, organic matter is attached to the surface of bone meal, which causes pollution and affects its quality.

2) Dicalcium phosphate. Dicalcium phosphate mainly provides phosphorus, with a phosphorus content of 14%-16% and its utilization rate is high, and dicalcium phosphate is mostly used as a phosphorus source in fish feed. It is worth noting that the fluoride content of calcium diphosphate is too high due to lax beneficiation and defluoride measures, which will adversely affect the growth of fish.

The state stipulates that the fluoride content of calcium diphosphate does not exceed 0 18%. 3) Stone powder and shell powder. Both stone powder and shell powder provide calcium, of which the calcium content can reach more than 35%.

4) Table salt. Table salt is rich in sodium and chloride, which are generally lacking in plant-based feeds. Therefore, it should be supplemented in the feed.

In addition, the addition of table salt can promote appetite and help sensitive digestion.

1. Palatability, fish feed is more palatable after processing, and it is convenient for fish to eat.

2.Convenient storage is not delayed, because the fresh macro vertical live feed is not resistant to storage, so the production of feed can be stored for a long time.

3.Balanced nutrition, by making fish feed, the protein content in the feed can be made in line with the growth of fish, and the problem of a single nutrient component of a certain bait can be solved.

There are many ways to make fish feed, and the recipe is often different for different fish. For example, if you feed grass carp or silver carp, you can use straw flour with bean cake, dough cake, cornmeal, and add a small amount of bone meal and salt. If you are feeding tilapia, you can make it with a mixture of bran, soybean cake, fish meal, cornmeal, locust leaf powder, barley flour, etc.

There are many ways to make fish feed, and the recipe is often different for different fish. For example, if you want to feed grass carp or silver carp, you can use Zhengzen rent straw flour with bean cake, flour, cornmeal, and add a small amount of bone meal and salt. If you are feeding tilapia, you can make it with a mixture of bran, soybean cake, fish meal, cornmeal, locust leaf powder, barley flour, etc.

1. Timing: Feeding the fish usually needs to be fed regularly, and fed at a fixed time every day, so that it can form a certain habit. It should be noted that due to the number of feedings per day, there should be a certain interval so that the fish can digest and digest the food, so as not to eat too much and suffer from enteritis.

2. Quantitative: Every time you feed the fish, you must control the amount of food, usually if you raise fish at home, you can feed it until seven or eight minutes full, so that the fish will not excrete too much, and at the same time, it can also avoid lifting the residual bait in the water body, which is very helpful to the water quality. In the case of large-scale farming, it is necessary to be fed, and long-term semi-starvation will affect growth.

3. Positioning: When feeding the fish, it must be in a fixed place, so that it is convenient to concentrate on feeding, if the feeding place is too scattered, the fish are easy to eat, so that the feed will be wasted.

There are many <> forage fish, such as trout, medaka, mosquito-eating fish, and wheat ear fish. Usually forage fish is used to feed some large carnivorous fish, such as Arowana, map fish, monk fish, etc., compared with ordinary fish food, forage fish is more nutritious, and it is also of great help to the growth of fish. Mosquito-eating fish, trout, etc., which are generally used as feed fish, are not large in size and relatively clean.

Fish feed is generally made from rice bran, bran, soybean cake, fish meal, barley, yeast meal, straw meal, corn meal, sweet potato rattan powder, green fodder and other ingredients. Different flavors of fish need to be prepared according to different fish species. Fish commonly used grandchildren answer feed formula:

Bran, fish meal, soybean cake, barley, green fodder. The main raw materials of fish include imported fishmeal, soybean grains, crude fiber, vitamins, corn, etc.

Fish can be earthworms, diced raw meat, leeches, dough, fish eyes, fish intestines, rice grains, shrimp, meat maggots, corn bugs, chewing gum, water bugs, grasshoppers, small fish, and chicken intestines as bait.

The adaptability of bait is very wide, some are first-class bait, and some are Puze Huitong bait. Therefore, only by comparing and screening the bait can we get a good harvest.

The feed of the aquarium is mainly divided into: floating feed, sinking feed, pellet feed, and flake feed. Floating Feed:

Suitable for top fish or big fish. Submerged feed: suitable for bottom fish, snails and shrimps.

Flake feed: It can take into account the upper, middle and lower tropical fish, and is more inclined to middle and upper fish.

What feed do fish generally feed?

Fish farming is a very interesting and highly profitable sport, which can not only satisfy people's hobbies, but also provide people with rich protein and nutritious fish. In the process of fish farming, choosing the right feed is crucial, so what exactly is suitable for fish farming?

1. Natural feed

Natural feed refers to feed with naturally occurring food as the main raw material, such as plankton, plants, shellfish and mammoths. This kind of feed contains a variety of nutrients, which is easy to be absorbed by fish, which is of great help to the growth and development of fish, and also conforms to the cycle law of nature, and Paiqiao has no pollution to the environment.

However, the amount of natural feed is affected by the region and season, and the stability of the feed cannot be guaranteed, and there are also problems such as unstable quality.

2. Artificial feed

Artificial feed refers to the feed mixed with various nutrients synthesized, which can be accurately formulated according to the characteristics of fish species, growth stage, nutritional needs, etc., in order to achieve the best feeding effect.

Compared with natural feed, artificial feed is not affected by the regional season, has the advantages of stability and controllable quality, can ensure the adequacy of feed, and can also add various additives to improve the immunity and growth rate of fish.

3. Mixed feed

Mixed feed refers to the feed made from a mixture of natural feed and artificial feed, with the aim of combining the advantages of the two feeds and reducing the deficiencies of each feed itself.

The formula of mixed feed can be adjusted according to different varieties, growth stages, regional climate and other factors, which can meet the nutritional needs of different fish and is a more suitable feed for breeding.

4. Suitable for different kinds of fish feed

For different species of fish, the feeding habits are different, so when choosing a feed, it is necessary to choose according to the characteristics of the fish itself.

Herbivorous fish, such as grass carp, carp, mandarin fish, etc., the main food is plants, so natural feed and mixed feed are more suitable choices. Carnivorous fish, such as crucian carp, tilapia, sea bass, etc., mainly eat other fish, shrimp, etc., so it is necessary to choose artificial feed with high protein and high nutrition.

In short, it is very important to choose the right feed for fish farming, which needs to be selected according to the characteristics of fish species, growth stage, eating habits, etc., and adjusted and optimized according to the actual situation.
