AI Technical Summary

Technical Problem

Existing feeds result in low survival rates and long domestication times for largemouth catfish. Furthermore, catfish fry have a natural instinct to refuse artificial feed, leading to high mortality rates and long domestication cycles during the domestication phase.

Method used

A domestication feed for largemouth catfish was designed, containing components such as single-cell protein source, animal protein source, plant protein source, fat, vitamins, minerals, carbohydrates and amino acids. It is used to stimulate feeding through smell and taste, and combined with a multi-stage feeding method to gradually transition to a completely artificial feed.

Benefits of technology

It improved the survival rate of domesticated catfish to 95.33 ± 3.80%, the weight gain rate to 142.86 ± 7.85%, significantly increased the activity of intestinal trypsin and lipase, and shortened the domestication period.

Abstract

The application discloses a domesticated bait for large-mouth catfish and a domestication method. By controlling the components such as protein sources in the domesticated bait and the domestication method, the survival rate of the domesticated catfish is effectively improved, the domestication period is shortened, and the growth of the large-mouth catfish is promoted. In the case of as low as possible domestication cost and management difficulty, the domestication success can be ensured, and the survival and growth are promoted. By using the technical scheme, the survival rate of the domesticated large-mouth catfish is as high as 95.33±3.80 %, the weight gain rate WGR reaches 142.86±7.85 %, the trypsin activity in the intestine of the large-mouth catfish fed by the application is as high as 5.73±0.34 U / mg, and the lipase activity is as high as 120.33±6.21 U / mg.
