Silurus meridionalis feed and processing method thereof

Abstract

The invention discloses a silurus meridionalis feed, which comprises an animal protein source, a plant protein source, fat, vitamins, minerals and carbohydrates, wherein the animal protein source accounts for 30 to 40 percent, the plant protein source accounts for 25 to 40 percent, the fat accounts for 6 to 8 percent and polyunsaturated fatty acid accounts for not less than 1.5 percent. The processing method comprises the following steps of: crushing and / or grinding all components of the feed; stirring various raw materials in a stirrer; and packaging the stirred feed. The feed can improve the survival rate and disease resistance of silurus meridionalis, has good effect of promoting growth, can completely replace trash fish to serve as the fish bait of the silurus meridionalis, and can effectively reduce the culture cost of the silurus meridionalis to achieve the maximum economic benefit.

Description

technical field [0001] The invention relates to a feed, in particular to a largemouth catfish feed and a processing method. Background technique [0002] Largemouth catfish is a ferocious carnivorous fish with a large appetite and a wide range of food habits. When the bait is insufficient, it will kill each other, which seriously affects the survival rate. Feeding is generally dominated by carnivorous bait, and it can also be fed with granular bait through artificial domestication. The largemouth catfish is a bottom fish. During the day, it hides in groups in low-light hiding places at the bottom of the water, and at night it disperses into the water layer to look for food. The living water temperature is 0-38°C, the suitable water temperature for growth is 12-31°C, and the optimum temperature is 25-28°C. It is a ferocious carnivorous fish that preys on various fish, shrimps and aquatic insects. The phenomenon of cannibalism is serious, and it can even swallow the same ki...

AI Technical Summary

Problems solved by technology

Artificial breeding is mainly based on pond culture and cage culture, and mostly feeds fresh miscellaneous fish and animal offal. In the case of insufficient bait, mutual killing is serious, often causing huge losses

Due to the overfishing of wild aquatic resources and the deterioration of the water body environment, wild miscellaneous fish resources are almost exhausted, and animal offal bait also has problems of high cost and low supply, which often cause largemouth catfish farmers to lack fresh bait or the breeding cost is too high As a result, the largemouth catfish breeding process caused serious mutual killing and low survival rate
