Key Points and Precautions for High-Density Fish Farming
Abstract High-density cage fish farming adapts to a very wide range of waters. It can be set up in lakes, reservoirs, and rivers; as long as the water depth is greater than the height of the cage, farming can be carried out. During this period, 60-80 common carp fingerlings with a body length of 13-20 cm can be stocked per cubic meter. The rearing period is 2

Detailed Explanation of Key Points of Off-Season Crayfish Farming Technology
Abstract Farming pond: Choose a pond facing the sun and sheltered from the wind, dig several strip-shaped trenches of the same size in the pond, clean the pond bottom, filter the water and fill it, then plant water hyacinth and other aquatic plants, and finally install a microporous aeration pipe in the strip-shaped trenches. Shed frame: Two layers of thick plastic film need to be covered on the built shed frame. Stocking fry: Fry can be stocked in mid-to-late November, with about 50 kg of semi-commercial shrimp stocked per mu. Feeding: Feed once a day, and make sure the dissolved oxygen content in the water is sufficient.

How is it that the per-mu yield of a fish pond can reach over a thousand jin?
Summary The per-mu yield of fish farming in ponds is generally around 1000 jin, and with high yields it can reach around 4000 jin. Different fish species and rearing methods will affect the yield. Pond fish farming generally adopts a polyculture model, and the stocking density of fish is determined according to the size of the fish species, but it should be noted that before stocking, they must be soaked and disinfected in a 4% salt water solution for about 10-15 minutes.
