Matters needing attention for fishery seedling
The newly built pond was soaked in water for 1 to 2 days, and then disinfected. The old pond must drain the water, thoroughly remove the sludge and weeds, use ploughing, sun exposure and washing to promote the oxidation, decomposition and removal of organic matter, and finally carry out disinfection. Commonly used disinfectants are quicklime, bleach, sodium dichloroisocyanurate. The disinfection method generally injects water into the aquaculture pond for 10 to 30 centimeters. After dissolving in the water, the disinfectant is thrown into the pond. Rinse the cement pool with potion many times, and then rinse with clean water. For example, in an enterprise, Penaeus vannamei is disinfected 15 days before stocking.

High viscoelastic surimi products (1)
In the processing and production of all kinds of surimi food, the choice of fish species and the freshness of fish are very important; it affects the elasticity of the products, so there is a certain limit on the amount of soybean and wheat protein powder mixed in surimi raw materials, and too much will weaken the elasticity of the products. In order to solve the elasticity problem of aquatic surimi products, a new method was used to make fish protein or mix it with plant protein to make protein fiber, and then mixed with surimi to produce surimi food with excellent viscoelasticity, which can make C-grade low-grade surimi elastic. Enhanced to more than A grade. The production method changes the original

Comprehensive utilization of idle fish ponds in winter
The cultivation of adult fish in winter fallow ponds can not only increase production, but also adjust the "summer shortage" of the aquatic product market. Due to the short culture period and low temperature, the following techniques should be adopted: first, early stocking, that is, after the fish species are merged into the pond, in order to make full use of the growing period. The stocking amount is calculated with a maximum water depth of 2 meters, generally 125 to 150 kilograms per mu. The stocking proportion is generally about 40% for silver carp, 10% for bighead carp, 30% for grass and carp, and 20% for green carp and carp. Release fish culture

What are the symptoms of fish when they are sick?
Generally speaking, we have some key points for observing the appearance of fish: 1. Body color: if you often observe the fish you raise, you will know what its normal color looks like.

Processing of quick-frozen large silverfish
Quick-frozen silverfish are exported to Japan, Southeast Asia and Europe, especially popular with Japanese consumers. With the continuous improvement of the output of large silverfish in the reservoir, quick-frozen big silverfish has become one of the export aquatic commodities with high exchange rate in China. The main results are as follows: 1. Fresh-keeping and transportation of raw fish the large silverfish has a small body and thin skin, which is easy to rot and deteriorate, and the production is highly seasonal. In order to ensure the quality of silverfish, when fishing, you can disembark with ice and keep it fresh at the first time.

How to raise adult turtles
The area of adult turtle pond is 100 square meters, and about 10 young turtles can be released per square meter. The water of the turtle pond should be kept light green (about 30 cm transparency). If the transparency is too large, the turtle will produce sense of security; if the transparency is too small, the water is brownish green and the water quality is too fat, it is easy to cause eutrophication, which is also disadvantageous to turtle breeding. The feeding methods of adult turtles vary from season to season. If the water temperature is low in spring and autumn, and adult turtles do not come out early or late, they should be fed at 10:00 in the morning.

There is knowledge in raising eel to prevent disease.
In July, August and September every year, the climate is hot, so farmed eel is prone to serious diseases. Its main manifestations are as follows: 1. Gill rot caused by parasites or bacteria. 2. Hepatonephrotic syndrome caused by feed or management factors. The high mortality rate and difficult treatment of these two diseases are the biggest headaches for many farmers. According to the follow-up survey in recent years, I have expressed some opinions on this issue. First, give priority to prevention, to avoid the occurrence of diseases, the specific operations are as follows: 1. Regular use of insecticides
