Puffing and sinking compound feed for takifugu obscures larvae

Abstract

The invention discloses a puffing and sinking compound feed for takifugu obscures larvae. The compound feed comprises the following components: fish powder, soybean meal, cottonseed meal, fermented soybean meal, flour, beer yeast, calcium dihydrogen phosphate, fish oil, puffing blood powder, cuttlefish paste, a mineral mixture and a vitamin mixture. The compound feed further comprises soybean lecithin and a liver and gallbladder protecting agent. According to the compound feed, the feeding operation management can be simplified, the cultivation cost can be reduced, and the growth and quality of the takifugu obscures larvae can be improved.

Description

technical field [0001] The invention relates to the field of fish feed, in particular to the field of puffer pufferfish feed. Background technique [0002] Takifugu obscurus (Takifugu obscurus) belongs to the genus Fugu in the family Fuguidae of the order Fuguformes, commonly known as puffer fish, and is one of the few species in the genus Fugu that has the habit of breeding and migrating in sea and fresh water. Pufferfish obscurus is delicious in meat, rich in protein and fat, and is a rare fish with a high market price and sales in short supply, so it is deeply loved by consumers. Due to its good adaptability to freshwater and high economic value, this fish has been developed as a new species of freshwater aquaculture in my country, and a relatively complete large-scale artificial breeding and intensive aquaculture technology system has gradually formed. However, due to the serious lag in the research on the pure nutrient requirements of Orient obscura and the development...

AI Technical Summary

Problems solved by technology

However, due to the serious lag in the research on the pure nutritional requirements of Orient obscurus and the development of special compound feeds, in actual aquaculture production, eel and soft-shelled turtle powder are usually used for feeding, although to some extent it can maintain the normal operation of puffer fish farming , but different fish have different requirements for nutrients. Inappropriate nutrition may have adverse consequences on fish health, growth rate, etc. or increase the cost of breeding

At present, the deficiencies in the low conversion rate of powder feed, large water pollution, difficult quality control, high cost, time-consuming and labor-intensive operation have seriously restricted the sustainable development of puffer fish farming industry.
