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 70.0% pregelatinized starch 22.0% puffed soybeans 1.0% fish oil 1.0% beer yeast 3.0% minerals 1.5% Calcium Dihydrogen Phosphate 1.0% Choline chloride 0.3% multidimensional 0.2%

[0048] When adopting the feed of this example in the aquaculture laboratory of Fujian Tianma Feed Co., Ltd. to breed Japanese eel white eel, the breeding time was February 2009, a total of 20 days, 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 white 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 64.5% pregelatinized starch 23.5% puffed soybeans 2.0% fish oil 0.8% beer yeast 3.0% minerals 2.0% Calcium Dihydrogen Phosphate 0.7% Choline chloride 0.3% multidimensional 0.2% Enveloped Vitamin C 0.1% Antioxidants 0.02% Kelp powder 1.5% Shrimp Shell Powder 1.1% salt 0.28%

[0051] When adopting the feed of this example to breed Japanese eel white eel in the Fuqing Keyu farm, the breeding time was 25 days from February to March in 2009, and 3 eel ponds were implemented. The Japanese eel that ingested the feed of this example can eat vigorously, the feed has good viscoelasticity, good stability in water, less water exchange, high feed conversion rate, faster growth of white eel, reduced number of three types of seedlings, and...

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 66.5% pregelatinized starch 23.0% puffed soybeans 1.0% fish oil 1.0% beer yeast 3.0% minerals 1.5% Calcium Dihydrogen Phosphate 0.5% Choline chloride 0.3% multidimensional 0.2% Enveloped Vitamin C 0.1% Antioxidants 0.02% Kelp powder 1.3% Shrimp Shell Powder 1.3% salt 0.28%

[0054] When adopting the feed of this example to breed Japanese eel white eel in the Fuqing Keyu farm, the breeding time was 25 days from February to March in 2009, and 3 eel ponds were implemented. The Japanese eel that ingested the feed of this example can eat vigorously, the feed has good viscoelasticity, good stability in water, less water exchange, high feed conversion rate, faster growth of white eel, reduced number of three types of seedlings, and...

Abstract

The invention discloses powdery compound feed for the elver stage of Japanese eel. The powdery compound feed comprises the following components in percentage by weight: 64.0-72.0% of steam-dried fish meal, 21.5-23.5% of pre-gelatinized starch, 0-2.0% of puffed soybean, 0.5-1.0% of fish oil, 1.0-3.0% of beer yeast, 1.0-2.0% of mineral substances, 0.5-1.0% of calcium dihydrogen phosphate, 0.3% of choline chloride and 0.2% of vitamins. The feed can provide sufficient nutrition for the elver breeding stage of the Japanese eel and reduce the eek breeding cost.

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 white 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...
