Experience and Technical Key Points for Raising Yellow Catfish in Paddy Fields
1. Paddy field selection. It requires convenient water intake and drainage, sufficient water source, good water quality, and strong water retention. The area is generally 8-10 mu per plot. 2. Field engineering. Dig "tian"-shaped or "jing"-shaped ditches, with a ditch width of 3-5 m and a depth of 0.8-1 m, build water intake and drainage canals well, seal the water intake and drainage outlets with fine-mesh nets,

Key Technical Points for Natural Breeding of Yellow Catfish in Ponds
In recent years, artificial breeding techniques for yellow catfish have made some breakthroughs, and many places have attempted large-scale production of fry and fingerlings. However, due to the particular structure of the gonads of yellow catfish, both the fertilization rate in artificial breeding and the survival rate of fry and fingerlings are relatively low, so the price of fry and fingerlings is relatively high. Zheng

Detailed Explanation of Key Techniques for Monoculture of Yellow Catfish in Ponds
1. Pond preparation. The fish pond is rectangular, oriented east-west, with an area of 1.5 mu and a water depth of 1.5-1.8 m. It has convenient drainage and irrigation, and is equipped with one 1.5 kW floating spray aerator. The pond bottom is flat with little silt, which facilitates harvesting. Ten days before the fry are stocked, 100 kg of quicklime per mu is mixed with water

Key Technical Points for Semi-Artificial Propagation and Culture of Yellow Catfish
Because the testes of male yellow catfish are dendritic in shape, semen cannot be squeezed out; therefore, in current fully artificial propagation, the usual practice is to kill the male fish, remove the testes, cut them into pieces, and perform artificial insemination, after which all the male fish die. After manual egg squeezing, the vast majority of female fish also die. Fully artificial
