Sebastes schlegeli adult fish compound feed and preparation method thereof

Abstract

The invention provides Sebastes schlegeli adult fish compound feed and a preparation method thereof. The compound feed is composed of fish meal, fermented soybean meal, husked soybean meal, high-gluten flour, fish oil, bean oil, vitamin premix, trace element premix, Vc, betaine, Chinese rhubarb powder, scutellaria root powder, golden cypress powder, allicin and beer yeast powder according to specific quantity. The compound feed belongs to the technical field of aquatic feed. A consistent technical means of adding fresh fish into Sebastes schlegeli feed in the prior art is changed, the compound feed is obtained by effectively combining specific components according to specific content, and a new optimal replacement ratio of fish meal and vegetable protein is provided, so that feed cost and feed coefficient are lowered, and water pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed in the field of feed, in particular to a compound feed for adult fish of Xu's flat scorpionfish and a preparation method thereof. Background technique [0002] Xu's flat scorpionfish ( Sebastesschlegeli ) belongs to the order Scorpioniformes, Scorpionidae, Scorpius genus, aliases black scorpion, black fish, bristle hair, etc., mainly distributed in my country's Bohai Sea, Yellow Sea, East China Sea and foreign countries such as the Korean Peninsula, Japan, and the Sea of ​​Okhotsk. This fish has strong disease resistance and fast growth. It can survive the winter naturally in the northern coast of my country. Its meat is tender and delicious, and it is deeply loved by consumers. It is one of the excellent varieties for breeding. At present, small miscellaneous fish are mainly used for feeding. It takes time and effort to feed the bait, which not only aggravates the damage to offshore res...

Problems solved by technology

[0003] For this reason, in a paper titled "Reproductive Biology and Artificial Breeding Technology of Xu's Flatfish", two formulas of artificial compound feed for Xu's Flatfish are disclosed, the ingredients are fresh miscellaneous fish, fish meal, yeast, bean cake Meal, peanut cake, bran, cornmeal, fish oil, soybean oil, vitamin premix, trace element premix, methionine, lysine, of which the content of fresh trash fish is 30%, fish meal is 20% or 0%, and there are According to the experimental data in the paper, the two formulas have the following problems: 1. The feed efficiency is low and the feed coefficient is high; 2. A relatively high proportion (30%) of fresh trash fish is used, and the quality of chilled trash fish is uneven, and the finished product Difficult to store, among which there are many pathogenic bacteria, high feed coefficient, heavy water pollution, and excessive reliance on chilled fish caught in the ocean; one of its formulas has a high proportion of fish meal (20%), and fish meal is the main protein source in compound feed, but currently The rising price of fishmeal has seriously hindered the sustainable development of the aquaculture industry. Therefore, finding high-quality fishmeal substitute raw materials and studying the addition ratio of alternative protein sources have become key issues for the sustainable development of the aquaculture industry.

However, in the actual breeding process, it was found that substituting plant protein for fish meal often resulted in unsatisfactory growth, and the feed factor could not be reduced. The main reasons were nutritional imbalance and poor palatability.

Simultaneously in this application, also added a variety of a large amount of Chinese herbal medicines, increased the cost of feed
