Detailed Explanation of High-Yield Breeding Techniques for Grass Carp Fingerlings

In recent years, in order to increase breeding profits, the vast number of fish farmers have changed the previous stocking model, from the previous dominance of silver carp to the current dominance of bottom-dwelling fish. Nowadays, it is quite popular to give grass carp as gifts at the end of the year, so in recent years grass carp seed has sold quite well.

In recent years, in order to increase breeding profits, the vast number of fish farmers have changed the previous stocking model, from the previous dominance of silver carp to the current dominance of bottom-dwelling fish. Nowadays, it is quite popular to give grass carp as gifts at the end of the year, so in recent years grass carp seed has sold quite well. In order to adapt to the situation and also to increase profits, in recent years our farm's fingerling breeding has also increased the proportion of grass carp seed and the stocking density. Through exploration in recent years, the staff of our farm have greatly improved their skill in raising grass carp fingerlings of the current year, with an average yield per mu reaching 400 kg, and high-yield ponds exceeding 500 kg. Today I will briefly introduce our farm's techniques for raising grass carp seed of the current year.

1. Preparation of the pond. Our farm's ponds are all divided for fingerling breeding after the summer fry stage is finished. In some places where summer fry are not used, it is enough to carry out pond clearing and disinfection as before, but new water should be added about one week before the summer fry enter the pond, and when adding new water, an 80-mesh sieve silk water inlet bag should be used to filter out wild and miscellaneous fish.

2. Stocking model and ratio. To raise grass carp fingerlings of the current year well, the stocking model is very important. If the quantity is too small, the yield cannot keep up; if the quantity is too large, they will not grow big. At the same time, attention should be paid to species combination. Generally, 8000 summer fry of grass carp of the current year are stocked per mu
