Problems solved by technology

At present, the spotted mandarin fish on the market are mainly wild resources, and they are scarce.
Due to the slow growth and small size of wild mandarin mandarin fish, the benefit of artificial large-scale breeding is low, which limits the development of artificial culture of mandarin mandarin fish

Embodiment Construction

[0021] The present invention will be further described below with embodiment.

[0022] In this example, the hybrid parents of Siniperca sinensis (female parent) and Siniperca chinense (male parent) are fine-bred parents Qiupu Siniperca chinense and Siniperca chinense (Sirina chinensis) that have been bred for a long time by Chizhou Qiupu Special Aquatic Products Development Co., Ltd. ). Concrete crossbreeding techniques and methods include the following steps:

[0023] l. Intensive cultivation of parents

[0024] The hybrid female parent Qiupu spotted mandarin fish used in this embodiment is 3 full ages and more than 0.5 Kg in body weight, and the hybrid male parent Qiupu spotted mandarin fish is 2 full ages and more than 1.0 Kg in body weight. In the autumn of the previous year of breeding, the parents were placed in different cages or ponds for intensive cultivation. During the cultivation period, the Qiupu mandarin fish is fed with palatable live bait fish, and the Qiupu...

Abstract

The invention discloses a breeding method of hybrid mandarin fishes. The breeding method comprises the following steps of a, parent selection, b, artificial spawning and insemination, c, hatch management, d, fry rearing, and e, fry taming feed. According to the method, siniperca scherzeri and siniperca chuatsi which are bred through multiple generations are used as hybrid parents, the hybrid mode of siniperca scherzeri (o+)*siniperca chuatsi (o) is adopted, and new-type mandarin fishes are generated. The hybrid mandarin fishes of the new type are developed for the high-range fresh water aquaculture industry, are superior to siniperca chuatsi in meat taste and disease resistance, higher than siniperca scherzeri in growth speed, capable of eating non-live fishes, good in economic trait, and convenient to culture in large scale through manpower.

Description

technical field [0001] The invention belongs to the technical field of fish farming, and in particular relates to a hybrid breeding technology for producing a new variety of spotted mandarin fish with obvious morphological characteristics and growth advantages by utilizing the interspecific hybrid breeding technology of fish. Background technique [0002] Siniperca scherzeri (Siniperca scherzeri) and Siniperca chuatsi (Siniperca chuatsi) both belong to the order Perciformes, belong to the family Siniperca genus, and are both high-grade freshwater aquatic species. Since the 1980s and 1990s, the cultivation of mandarin fish has been widely carried out all over the country, and good economic and social benefits have been achieved. However, the mandarin mandarin fish needs to feed on live fish for life, and live fish of different sizes need to be fed in different growth stages. This special food habit of mandarin fish not only increases the cost and difficulty of breeding, but a...
