Problems solved by technology

Although the currently commercially available prawn feed ingredients have certain nutrients and can satisfy their growth, their protein source is mainly imported fishmeal, and the cost is relatively high.
And because the current feed utilization rate is not high, in aquaculture practice, excessive nutrients (especially nitrogen and phosphorus) in the diet are excreted into the aquaculture water environment through metabolism, resulting in serious water pollution and eutrophication, which seriously threatens shrimp. Sustained and healthy development of the industry

Abstract

The invention discloses a low carbon type litopenaeus vannamei ecological fodder and a preparation method thereof. The fodder comprises the following components: bean pulp, fish meal, flour weevil powder, chicken powder, inkfish powder, earthworm powder, fly maggot powder, silkworm chrysalis meal, shrimp head shell powder, rapeseed dregs, rice bran, wheat flour, corn flour, enteromorpha algae powder, saccharomyces cerevisiae, fish oil, soybean oil, phospholipid oil, folium mori flour, monocalcium phosphate, choline chloride, compound ore, compound vitamins, vitamin C phosphate and phytase. The fodder has scientific compatibility of medicines; the fish protein is replaced by the insect protein mainly from flour weevil, so that the dependence on the imported fish meal can be reduced, the cost is lowered and the low carbon purpose is achieved; the bioactive substances including folium mori flour, alga, and the like, are added, so that the factor interference of anti-nutrients can be reduced; the prawn can fully utilize the fodder; the growth performance of the prawn can be promoted; the emission amount of nitrogen and phosphorus can be reduced, so that the breeding environment of the prawn can be improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a low-carbon Litopenaeus vannamei ecological feed and a preparation method thereof. Background technique [0002] Litopenaeus vannamei ( Penaeus vannamei Boone, 1931), also known as Penaeus vannamei and white-footed shrimp, is native to the coastal waters of South America. It has many characteristics such as large individual, beautiful meat, low nutritional requirements, fast growth speed, and strong resistance to stress. It is the world's most farmed shrimp. One of the three most productive species. Since the 1990s, Litopenaeus vannamei has become the largest prawn species in my country, accounting for more than 90% of the total prawn production. [0003] With the continuous expansion of the farming scale, it also promotes the rapid development of the shrimp feed industry. Although the currently commercially available feed ingredients for prawns have certain nutrients an...
