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 this example feed to breed Japanese eels in the aquaculture laboratory of Fujian Tianma Feed Co., Ltd., the breeding time was 50 days from February to March 2009, and 3 experimental aquariums were implemented. Adult Japanese eels fed the feed of this example can eat normally, the viscoelasticity of the feed is good, the stability in water is the best, the amount of water exchange is reduced, the feed conversion rate is high, and the growth of adult eels is 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] When adopting the feed of this example to breed Japanese eel adult eels in Keyu farm in Fuqing, the breeding time was 70 days from March to May in 2009, and 3 eel ponds were implemented. Adult Japanese eels fed the feed of this embodiment can eat vigorously, have good feed viscoelasticity, best stability in water, reduced water exchange, high feed conversion rate, fast growth and natural body color.

Embodiment 3

[0052] Embodiment 3: the content of each component after the present invention adds an appropriate amount of additives is as follows:

[0053] steam dried fish meal

[0054] When adopting the feed of this example to breed Japanese eel adult eels in Keyu farm in Fuqing, the breeding time was 70 days from March to May in 2009, and 3 eel ponds were implemented. Adult Japanese eels fed the feed of this embodiment can eat vigorously, have good feed viscoelasticity, best stability in water, reduced water exchange, high feed conversion rate, fast growth and natural body color.

Abstract

The invention discloses a powder compound feed for adult Japanese eels. The feed comprises the following components in percentage by weight: 52.5 to 60.0 percent of steam-dried fish meal, 24.0 to 26.0 percent of pre-gelatinized starch, 7.0 to 11.5 percent of extruded soybean, 0.5 to 1.5 percent of fish oil, 2.0 to 4.0 percent of beer yeast, 1.0 to 2.0 percent of mineral, 0.5 to 1.0 percent of monocalcium phosphate, 0.3 percent of choline chloride and 0.2 percent of multi-vitamin. The feed can supply sufficient nutrition at an adult Japanese eel breeding stage and eel breeding cost is lowered.

Description

technical field [0001] The invention relates to the field of compound feed for fish, in particular to the field of compound feed for adult Japanese eels. 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 the a...
