Problems solved by technology

[0002] Copperfish is an important fish in the Yangtze River Basin. Its delicious meat is very popular among people, and its demand is also very large. In recent years, due to changes in the natural environment, its reproduction speed has been too slow and its output has gradually declined. It is people's expectations to be able to obtain this type of fish species as a delicacy. In the prior art, someone proposes to increase the demand by artificially breeding it, but it is difficult to carry out artificial breeding due to its special constitution, and it is often difficult to use conventional feed. It will cause problems such as low immunity and serious diseases of copper fish, so how to feed copper fish has become an important means to increase production

Embodiment 1

[0013] The copper fish culture feed of the present embodiment, its raw material and percentage by weight are: 40 parts of fish meal, 5 parts of soybean oil, 10 parts of starch, 10 parts of flour, 20 parts of mineral premix, 20 parts of vitamin premix, 30 parts of astragalus polysaccharide At the same time, live snails and mussels are regularly released for predation. During the feeding process of live snails and mussels, the distribution method is adopted. Live snails and mussels are released at the same time, once every 5 days. The amount of live snails and mussels is 25 and 25 servings of snails are put in each time, and the amount of live snails and mussels is gradually increased according to the growth rate of the fish.

Embodiment 2

[0015] The copper fish breeding feed of the present embodiment, its raw material and percentage by weight are: 55 parts of fish meal, 7 parts of soybean oil, 12 parts of starch, 15 parts of flour, 23 parts of mineral premix, 22 parts of vitamin premix, 35 parts of astragalus polysaccharide At the same time, live snails and mussels are regularly put in for predation. The live snails and mussels are put in by spreading. The live snails and mussels are put in at the same time, once every 6 days. The amount of live snails and mussels is 30 and 30 servings of snails are put in each time, and the amount of live snails and mussels is gradually increased according to the growth rate of the fish.

Embodiment 3

[0017] The copper fish breeding feed of the present embodiment, its raw material and percentage by weight are: 70 parts of fish meal, 10 parts of soybean oil, 15 parts of starch, 20 parts of flour, 25 parts of mineral premix, 25 parts of vitamin premix, 40 parts of astragalus polysaccharide At the same time, live snails and mussels are regularly released for predation. During the feeding process of live snails and mussels, the distribution method is adopted. Live snails and mussels are released at the same time, once every 7 days. The amount of live snails and mussels is 35 and 35 servings of snails are put in each time, and the amount of live snails and mussels is gradually increased according to the growth rate of the fish.

[0018] Facts have proved that adopting the formula of the embodiment of the present invention two makes breeding effect the best, below in conjunction with embodiment two and comparative example verification effect of the present invention, concrete test...

Abstract

The invention discloses a coreius heterodon feed. The feed comprises the following raw materials in parts by weight: 40-70 parts of fish meal, 5-10 parts of soybean oil, 10-15 parts of starch, 10-20 parts of flour, 20-25 parts of a mineral premix, 20-25 parts of a vitamin premix and 30-40 parts of astragalus polysaccharide, and snails and freshwater mussel living bodies which are regularly fed forpredation. After a formula is adopted, the appropriate formula is adopted, high-quality protein required by the coreius heterodon is contained, in addition, the astragalus polysaccharide is reasonably matched, so that the anti-stress capability is improved, the injury is recovered, the immunity is greatly improved, in addition, the feed can be added as a predation bait, the influence of meat is supplemented, the activity rate is improved, and the resistance is further improved, so that the occurrence of diseases is reduced, the survival rate is improved, and the yield is increased.

Description

technical field [0001] The invention relates to a feed for fishery production and cultivation, in particular to a copper fish feed. Background technique [0002] Copperfish is an important fish in the Yangtze River Basin. Its delicious meat is very popular among people, and its demand is also very large. In recent years, due to changes in the natural environment, its reproduction speed has been too slow and its output has gradually declined. It is people's expectations to be able to obtain this type of fish species as a delicacy. In the prior art, someone proposes to increase the demand by artificially breeding it, but it is difficult to carry out artificial breeding due to its special constitution, and it is often difficult to use conventional feed. It will cause problems such as low immunity and serious diseases of copper fish. Therefore, how to feed copper fish has become an important means to increase production.
