Problems solved by technology

1. The process of dragging and carrying the net is a great test to the fish's physique, and the stress is very strong. In addition to the easy injury of the body surface, the loss of the internal organs, especially the liver, is also very large. Once the internal organs are damaged and the body surface is injured, it is very easy to Inducing diseases, many plans will not have immediate results; 2. The quality of water quality and bottom quality, including water body fertility, ammonia nitrogen and nitrite indicators, etc., will directly affect the fish's physique. Once the water is thin and muddy, the ammonia nitrogen and nitrite indicators will Too high, it is easy to cause fish disease after fishing
In order to solve the problem of starting fishing in hot water fish mode in high temperature period, the present invention provides a method of starting fishing for hot water fish, which is intended to improve the starting efficiency of fishing and increase the income of fishermen

Abstract

The invention discloses a hot water fish catching method. The method comprises the following steps: (1) feeding medicinal baits 10-20 days before catching; (2) supplementing a small amount of fertilizer and changing the bottom 6-8 days before catching; (3) spraying an anti-stress agent to the whole pond half a day before catching; and (4) lightly taking and putting the fish in the catching process to prevent the fish body from being injured, and carrying out oxygenation. By means of the hot water fish catching method, the damage to the fish in the net pulling and carrying process can be reduced, the catching survival rate is increased, the quality of the fish before catching is optimal, meanwhile, the catching method is used in a matched mode according to different breeding types, the higher and more stable catching effect is achieved, the market economy of the hot water fish can be obtained, and the worry of fish damage caused by stress after net hauling can be solved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for catching fish in hot water. Background technique [0002] Fishing in summer and autumn is called "hot water fish" by fishermen. Catching "hot water fish" can not only change the situation of "shortage in spring, shortage in summer, and crowding in autumn" of freshwater fish in the market in the past, so that there are fish in all seasons, but also tap the potential of fish farming in ponds and improve the efficiency of fish farming. However, improper fishing is also easy. Lead to fish floating head, pan pool and disease epidemic. With the adjustment of the aquaculture structure in my country's aquatic product market in recent years, the proportion of hot water fish has increased year by year. During the fishing process, due to high temperature and fish disease-prone season, farmers often cause fish diseases due to improper operation, making hot water...
