Odontobutis obscura parent fish feed and preparation method thereof

Abstract

The invention discloses odontobutis obscura parent fish feed. The odontobutis obscura parent fish feed is composed of the following components in parts by weight: 40-60 parts of eel grass, 40-60 parts of duckweed, 30-50 parts of corn meal, 10-20 parts of globe artichoke, 5-10 parts of hizikia fusiformis, 5-15 parts of potamogeton malaianus, 1-5 parts of pomegranate peel extract, 1-5 parts of persimmon leaf extract, 5-10 parts of crabshell powder, 5-10 parts of earthworm powder, 5-10 parts of pumpkin powder and 1-2 parts of sulphur neomycin. The odontobutis obscura parent fish feed has the advantages that the formula of raw materials is reasonable, a preparation technology is simple and feasible, the content of total protein in feed is high, energy required by growth of a parent fish can be provided, and egg laying amount is high; globe artichoke, potamogeton malaianus, hizikia fusiformis, pomegranate peel extract, persimmon leaf extract and sulphur neomycin are compounded, antibacterial and antiviral capabilities of the parent fish are improved, growth and development of the parent fish are promoted, diseases are fundamentally prevented and controlled, and the survival rate of fish fries is increased; palatability can be enhanced by virtue of the crabshell powder, the earthworm powder and the pumpkin powder, and the grazing rate of the parent fish is increased.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a broodstock feed for Channa chinensis and a preparation method thereof. Background technique [0002] Sand pond snakehead, commonly known as nerd fish and Tubu fish, is one of the rare species of freshwater fish. It has a large and broad head, slightly flattened, round abdomen, and flattened rear. Sand pond snakeheads like to live in the bottom of river ditches and lakes where there are many aquatic plants, rubble, rock crevices, and sand, and their swimming ability is weak. In winter, they hide in the deep water layer or under stones to survive the winter. They mainly feed on shrimp and small fish. Sand pond snakehead is widely distributed in the waters of various provinces in eastern my country. Although the individual is small, its meat content is high, and the meat is tender and delicious. It is loved by the people in the middle and lower reaches of the Yangtze Ri...

AI Technical Summary

Problems solved by technology

[0003]The natural yield of Channa nada is low. In recent years, due to overfishing, ecological deterioration and other reasons, its natural resources have decreased sharply and cannot meet the existing market demand. Therefore, The artificial breeding of sand pond snakeheads is gradually replacing natural fishing. With the initial success of artificial breeding, its breeding scale is gradually expanding. The breeding process, especially the breeding process of broodstock, is very important. The quality of broodstock is directly related As far as the number of eggs laid and the survival rate of the broodstock are concerned, there are currently many studies on the regulation of water quality in the breeding process of broodstock, but there are no specific and detailed reports on the special feed for broodstock breeding of sandfish.

In addition, for the common diseases in the breeding process of broodstock, the main treatment method is usually to prevent and treat the diseases by splashing chemical insecticides and fungicides, but it does not fundamentally improve the immune resistance of the fish itself, and the chemical reagents on the fish The residual amount is large, which does not meet the requirements of green fishery
