Key Points of Artificial Breeding Technology in Black Carp Aquaculture
The black carp is an excellent species for freshwater aquaculture in our country. It uses benthic organisms as feed, grows quickly, has a large individual size, tender flesh, and good flavor, and is high in fat and protein with abundant vitamin content, making it highly valued by the public and professional aquaculture households. The demand for fry is increasing day by

How can the survival rate of artificially bred black carp be improved?
The maturation period of black carp is later than that of silver carp, bighead carp and grass carp broodstock, and the gonads generally struggle to reach the standard for induced spawning at the end of stage IV. Therefore, a method of promoting maturation should be adopted. 15 to 20 days before induced spawning, seine the pond to check the maturity of the broodstock, and promptly give the less mature female and male broodstock

Detailed Explanation of Key Points in Artificial Breeding Technology for Yellow Catfish
Yellow catfish, also known as Wansi fish or Jiangsang fish, is a fecundity-type fish with strong adaptability and can be bred in various water bodies. It is easy to raise, commands a high price, and yields good returns. Its flesh is tender and its taste is delicious, making it a high-quality premium aquatic product that is increasingly favored by consumers.

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

Key Technical Points for Disease Prevention and Control in Artificial Scallop Seed Rearing
During artificial seed rearing, scallop larvae are highly susceptible to bacterial and fungal infections, which cause mass mortality. Among the common bacterial diseases are Vibrio species; one type, Vibrio anguillarum, specializes in decomposing organic matter and can break down the larval velum within a very short time. This symptom occurs especially within

Artificial breeding technology for bay scallop farming
Indoor artificial breeding of the bay scallop includes the following procedures: Parent scallop selection and fattening. The parent bay scallops selected generally have a shell height above 5 cm and are required to have full gonadal development; if they have not reached mature fullness, they are temporarily cultured for fattening. Feed types for parent scallop fattening

Methods of Artificial Nursing for Fawns and Key Points of Deer Farming Techniques
Every year during the production season, some newborn fawns are abandoned by their mothers, or weak fawns cannot get their mother's milk. Artificial nursing is the only way to save these fawns. 1. Location The artificial nursing room for fawns should be spacious and bright, with plenty of sunlight, clean and dry, and insulated (above 15°C), with 1-2 sq m of space per deer and an appropriate exercise area.
