High-yielding techniques of grass carp fry

In recent years, in order to increase the efficiency of culture, the majority of farmers have changed the previous stocking mode, from silver carp to the following sunken fish. Grass carp are popular at the end of the year, so grass carp seeds have been sold well in recent years. In order to adapt to the situation, but also to increase efficiency, I field these.

In recent years, in order to increase the efficiency of culture, the majority of farmers have changed the previous stocking mode, from silver carp to the following sunken fish. Grass carp are popular at the end of the year, so grass carp seeds have been sold well in recent years. In order to adapt to the situation, but also to increase efficiency, our farm over the past few years have also increased the proportion of grass carp seed culture and stocking density. Through the exploration in recent years, the level of grass carp farmed by the staff of our farm has been greatly improved, the average yield per mu has reached 400kg, and the high yield has exceeded 500kg. Here is a brief introduction to the technology of cultivating grass carp seeds in our farm.

1. Preparation of Tangkou. The pond mouth of our farm is to cultivate fish species in separate ponds after the end of summer flowers, and in some places, those who do not do summer flowers can just clean up the ponds and disinfect them as before, but the injection of new water should be about a week before the summer flowers enter the ponds. When adding new water, filter wild miscellaneous with 80-mesh sieve silk water bags.

2. Stocking mode and proportion. In order to raise grass carp species well, the stocking mode is very important. If the quantity is too small, the yield can not keep up, and if the quantity is too large, it will not grow. At the same time, attention should be paid to the collocation of the species. Generally, grass carp summer flowers are 8000 per mu.
