Problems solved by technology

This feeding method has the disadvantages of polluting the aquaculture water body due to the dissolution of the feed, causing huge waste, etc.
Especially in the breeding process of Japanese eels, the water quality is required to be fresh and the breeding conditions are relatively stable, otherwise it is very easy to get sick and cause huge losses

Embodiment 1

[0046] Embodiment 1: the most basic content of each component of the present invention is as follows:

[0047] steam dried fish meal

[0048] When using the feed of this example in the aquaculture laboratory of Fujian Tianma Feed Co., Ltd. to breed Japanese eel and black eel, the breeding time was 30 days from April to May in 2009, and 3 experimental aquariums were implemented. The Japanese eel that ingested the feed of this example could eat normally, the viscoelasticity of the feed was good, the stability in water was better, the amount of water exchange was reduced, the feed conversion rate was high, and the growth of the eel was normal.

Embodiment 2

[0049] Embodiment 2: the content of each component after the present invention adds an appropriate amount of additives is as follows:

[0050] steam dried fish meal

[0051] Kelp powder

[0052] When using the feed of this example to breed Japanese eel and black eel in Fuqing Keyu farm, the breeding time was 30 days from May to June in 2009, and 3 eel ponds were implemented. The Japanese eel that ingests the feed of this embodiment can eat vigorously, the feed has good viscoelasticity, good stability in water, less water exchange, high feed conversion rate, faster growth and natural body color.

Embodiment 3

[0053] Embodiment 3: the content of each component after the present invention adds an appropriate amount of additives is as follows:

[0054] steam dried fish meal

[0055] When using the feed of this example to breed Japanese eel and black eel in Fuqing Keyu farm, the breeding time was 30 days from May to June in 2009, and 3 eel ponds were implemented. The Japanese eel that ingests the feed of this embodiment can eat vigorously, the feed has good viscoelasticity, good stability in water, less water exchange, high feed conversion rate, faster growth and natural body color.

Abstract

The invention discloses an Anguilla japonica powdery mixed feed. The feed comprises the following components by weight percent: 61.0%-68.0% of fish meal dried with steam, 22.5%-24.0% of pregelatinized starch, 1.5%-4.5% of extruded soybean, 0.5%-1.5% of fish oil, 1.0%-4.0% of beer yeast, 1.0%-2.0% of minerals, 0.5%-1.0% of calcium dihydrogen phosphate, 0.3% of choline chloride and 0.2% of multivitamin. The feed disclosed by the invention can provide sufficient nutrients in the cultivation stage of Anguilla japonica and the cultivation cost of eels can be reduced.

Description

technical field [0001] The invention relates to the field of compound feed for fish, in particular to the field of compound feed for Japanese eel black larvae. Background technique [0002] Japanese eel (Anguilla japonica) is a species with high nutritional value. Compared with European eel (Anguill anguilla), Japanese eel has the advantages of vigorous food intake, faster growth, and higher temperature resistance. It is now the main species of eel farming in my country. one. In terms of nutritional research, scholars at home and abroad have carried out certain research on Japanese eel, and have also achieved good research results, but there is still a lack of in-depth research on its exact requirement, which limits the cultivation of Japanese eel to a certain extent. industry development. [0003] In the current eel breeding process, farmers usually use powdered compound feed to stir into balls and then feed the eels. This feeding method has the disadvantages of polluting...
