Method for cultivating a Procypris merus-Carassius auratus auratus hybrid and method for farming Siniperca chuatsi

Abstract

The invention relates to a method for cultivating a Procypris merus-Carassius auratus auratus hybrid and a method for farming Siniperca chuatsi; the first method comprises the steps of subjecting Procypris merus as a female parent and Carassius auratus auratus as a male parent to artificial spawning induction, then carrying out artificial fertilization to obtain fertilized eggs, and debonding andhatching the fertilized eggs to obtain the Procypris merus-Carassius auratus auratus hybrid. According to the invention, the Procypris merus-Carassius auratus auratus hybrid is creatively bred by taking Procypris merus as a female parent and Carassius auratus auratus as a male parent, and is used as a feed fish for culturing Siniperca chuatsi. The limits on large-scale cultivation of Siniperca chuatsi due to natural conditions of the middle and northern parts of China, feed fish cultivation seasons and other factors can be resolved; the methods are suitable for southern areas and northern areas of China, help ensure the marketing of Siniperca chuatsi products in cold seasons; the ratios of protein content, fat content, total essential amino acids to total nonessential amino acids in the products are high; the muscle quality of Siniperca chuatsi fed with the Procypris merus-Carassius auratus auratus hybrid is higher than that of Siniperca chuatsi fed with Carassius auratus auratus.

Description

Technical field [0001] The invention relates to the technical field of aquaculture, in particular to a breeding method of hybrid carp and crucian carp and mandarin fish breeding method. Background technique [0002] Mandarin fish, also known as sweet-scented osmanthus and seasonal flower fish, belong to the order Perciformes. Mandarin fish is delicious and nutritious, rich in protein and amino acids, with few spines but more meat, and is deeply loved by consumers. In recent years, the farming of mandarin fish has developed rapidly, and the farming area has been increasing. In mandarin fish farming, the supporting technology of bait fish is one of the key problems that must be solved. Grass carp and group head bream are mainly used for mandarin fish at the mouth feeding and seed breeding stage. Crucian carp and silver carp are mainly used for fingerling breeding stage, but four major home carp and carp, crucian carp, group head bream and other fish species cannot guarantee the m...

AI Technical Summary

Problems solved by technology

In the large-scale culture of mandarin fish in the area north of the Yangtze River, due to the limitation of natural conditions and the influence of factors such as the breeding season of bait fish, the culture of mandarin fish once a year mainly relies on dace which belongs to warm water as bait fish. Mode, which restricts the improvement of the economic benefits of the mandarin fish farming industry
