Method for promoting quality of Takifugu obscures marketable fish

Abstract

The method for promoting quality of Takifugu obscures marketable fish is a method for promoting artificial breeding marketable fish and belongs to the field of aquaculture. Trough innovation of culture mode, the quality of freshwater aquaculture marketable fish cultured by the technical method is promoted. The method comprises following five steps: 1 isolated culture containers are arranged in a pond where water quality is superior to III-grade water quality and fish are prevented from being in touch with pond bottom material; 2 culture with running water is carried out inside the containers, wherein the temperature of the water is 9 to 32 DEG C; 3 fish excrements are collected and transferred; 4. fish is fed on nuisance free mixed feed and / or natural biological bait; 5 after the size of fish reaches commercial specification, solarization sea salt is added to the water so that the water in the culture containers changes into salt-fresh water and then the fish becomes high-quality marketable fish after 3 to 30 days of culture. By means of the technical method of the invention, fish cultured in ponds can be like wild high-quality marketable fish; the quality problems of poor palatability, earthy taste, algae smell, mud smell or odor of residue chemicals can be solved.

Description

technical field [0001] The invention relates to a method for improving the quality of commercial fish, which belongs to the field of aquaculture, and specifically relates to a method for improving the quality of freshwater aquaculture commercial fish through the innovation of breeding methods. The application of this technical solution can make the farmed fish become an ecological high-quality commercial fish imitating the wild, and solve the problem of poor palatability of the farmed fish, and the commercial fish has a smell of soil, algae, mud or residual chemicals and other quality issues. Background technique [0002] my country is rich in aquatic resources and is an important source of animal protein intake for people. Pufferfish obscurus is a unique species of puffer fish in my country. Its meat is delicious and nutritious. It has been a famous aquatic product in the middle and lower reaches of the Yangtze River since ancient times. There is a folklore of "death to ea...

Problems solved by technology

[0005] The purpose of the present invention is to change the breeding conditions and parameters of the breeding environment through the innovation of the breeding environment, so as to overcome the low quality and poor palatability of the farmed commercial fish caused by the soil environment and its own feces pollution, and the commercial fish has an earthy smell, an algae smell, For quality problems such as muddy smell or odor of residual chemicals, the application of this technical solution can make farmed fish become ecological high-quality commercial fish imitating wild, and make pond farmed fish become "pond fresh" aquatic products, comparable to "river fresh" ", "Lake Fresh", "Seafood" and other natural ecological aquatic products
