The focus of fishery management in winter lays the foundation for next year's production.

Fishing in winter

With the advent of winter, the focus of fishery production began to shift gradually. To do a good job in the technical management of aquaculture in winter is the foundation for a bumper harvest of fishery production in the coming year. It is suggested that the majority of fishery science and technology demonstration households should take the following measures to do a good job in the management of fishery production in winter.

First, the early release of fish species can make the fish adapt to the new living environment early, eat early, grow earlier, and relatively prolong the growth period.

Second, timely catch aquatic products that meet the requirements of listing specifications. With the decrease of water temperature, most of the aquatic products meet the specifications of starting to catch on the market. It is necessary to start catching at the right time, seize the time to go on the market and sell, speed up the turnover of funds, and improve the efficiency of breeding.

Third, do a good job in the summary of fishery production. Focus on Tangkou production measurement, benefit analysis, filling in the "Science and Technology demonstration Household Handbook" and other data collection, sum up experience, pay attention to the application and promotion of new technology.

Fourth, rational feeding to improve disease resistance. In cold winter, when the water temperature is above 5 ℃, it is usually fed once every 3-5 days, with a daily dose of 1.0% of the fish's body weight, replenishing fish nutrition and improving the survival rate.
