Method for regulating and controlling meat quality of weever by changing salinity of feeding environment

Abstract

The invention discloses a method for regulating and controlling meat quality of weever by changing feeding environment salinity, and relates to the technical field of fish culture, the method comprises the following steps: step 1, selecting feeding objects and feeding environment: selecting juvenile weever which is robust in physique and uniform in specification as experimental objects, and equally dividing the selected experimental objects into two groups, one group is an experimental group, and the other group is a control group; 2, measuring the water quality of the culture ponds: detecting the salinity and other parameters of the culture ponds by using a water quality testing tool, and ensuring that the initial parameters of the two groups of culture ponds are consistent; 3, selectively adding salt specially used for the culture pond or introducing high-salinity natural seawater in proportion; and 4, calculating the addition amount. According to the method, the salinity of the water body after the weever passes through the fry stage is larger than that of the water body in the fry stage, so that the muscle fiber density of the weever is reduced, the hardness and chewiness of fish meat are reduced, the fish meat is tender, juicy and good in taste, and the effect of regulating and controlling the meat quality of the weever is achieved.
