Method for improving meat quality of parabramis pekinensis

Abstract

The invention provides a method for improving the meat quality of a parabramis pekinensis. The method comprises the following steps of 1) selecting and processing a pond, a squared pond which is convenient to drain and add water is selected, the pond is sterilized, a layer of fine sand and pebbles are laid at the bottom of the pond, and then a layer of decomposed organic fertilizer is laid; 2) processing water in the pond: water quality is control at a pH value between 5.5-6.5, water depth is 70-80 centimeters when fries are put in, water is added into the pond in every 3-5 days, 10-15 centimeters of water is added each time until the water depth reaches 180-220 centimeters, mixed liquid is added in and drainage is conducted everyday for 1-2 months before the parabramis pekinensis is on the market, and the mixed liquid is the filtrate of teas, garlic, dried tangerine peels after boiled, filtered and cooled; 3) stocking the parabramis pekinensis, the stocking density of the parabramis pekinensis is 350-400 kilograms per mu, the specification is 100-120 grams per fish, meanwhile, fries of salmons are stocked and fed with feeds, the feeding quantity of the feeds accounts for 0.1-0.8%of the total fish weight. The method significantly improves the quality of the parabramis pekinensis and the livability of the parabramis pekinensis and the salmon are improved under the premise of not changing the breeding effect of the parabramis pekinensis such as growth period and the like.

Description

technical field [0001] The invention belongs to the technical field of freshwater fish culture, and in particular relates to a method for improving the meat quality of bream. Background technique [0002] Bream, also known as Wuchang fish, is a typical herbivorous fish with rich nutrition, smooth and tender meat, high protein content, rich in trace elements such as copper and phosphorus, and has fast growth rate, strong adaptability, and high yield. The high characteristic is the main source of dietary protein for the common people; therefore, more and more farmers are focusing on bream farming, and the breeding methods and feeds are becoming more and more diversified. The purpose is to reduce the cost of breeding and increase production. The pursuit of high economic benefits has led to the fact that most of the artificially farmed bream are pot-bellied, close to round in shape, high in fat, loose in meat, heavy in muddy smell, and even infected with various pests and bacter...

[0003] In foreign countries, research on the artificial breeding technology of migratory Atlantic salmon has gone through a considerable period of time, and has successfully bred triploid salmon, all-female salmon, high-temperature-resistant salmon and other species, and successfully mastered the breeding technology of Atlantic salmon. A large number of fish eggs and fry are produced every year, but these results are limited to the cultivation of migratory Atlantic salmon in seawater. Although my country has invested tens of millions and spent more than ten years on salmon research, it has stagnated in basic applications due to various reasons. Research status, progress is slow. Shandong, Hebei, Beijing and western provinces are all engaged in cold-water fish farming and research, mainly rainbow trout, and the output is increasing at an annual rate of 20-30%. In the exploratory experiment, the survival rate of salmon is low and the cost of breeding is high
