Embodiment Construction

[0020] The present invention will be further described below through the implementation case in 2009.

[0021] 1) Broodstock and broodstock breeding

[0022] ①Choice of broodstock: In October 2008, the female parent of the mandarin fish was introduced from the national mandarin fish breeding farm, and the male parent of the big-eyed mandarin fish was selected from natural waters; the external shape should conform to the morphological characteristics of the big-eyed mandarin fish. Physically strong, free from disease and injury; male big-eyed mandarin fish is over 2 years old and weighs more than 0.75 kg; female mandarin fish with cocked mouth is over 3 years old and weighs more than 1 kg.

[0023] ②Cultivation of broodstock: The broodstock of Siniperca sinensis and Siniperca sinensis are cultivated in ponds of 1-3 mu respectively, with a water depth of 1.5-1.8 meters. The water quality complies with the provisions of the fishery water quality standard GB11607, in which the di...

Abstract

The invention relates to the technical field of aquaculture and aquatic breeding, in particular to a siniperca chuatsi and siniperca kneri hybridization and culture method which can be applied to home and collective siniperca culture, especially large-scale culture and breeding. The hybridization and culture method includes the steps of artificial insemination, fry rearing, fostering in pool, culture in pond and the like in details as follows: selecting siniperca chuatsi as female parent fish and siniperca kneri as male parent fish, and strengthening fostering, hatching fries by adopting artificial propagation technical measures of exogenous hormone injection for expediting delivery, running water stimulation for promoting delivery, artificial dry insemination and circular road running water hatching, and then breeding and culturing. The invention provides a novel hybrid siniperca kneri production method, and hybrid siniperca kneri produced by the method has a different shape from that of the female parent, has obvious growth advantage compared with the male parent and keeps the characteristics of fine and smooth meat quality and delicious taste of siniperca kneri.

Description

Technical field [0001] The invention relates to the technical field of fish breeding and reproduction, and belongs to the technical field of aquaculture breeding. Specifically, it relates to the hybridization and breeding method of mandarin fish with cocked mouth and big-eyed mandarin fish, which can be widely used in family and collective mandarin fish breeding, especially large-scale Breeding and breeding. Background technique [0002] Siniperca chuatsi (Siniperca chuatsi) and Siniperca kneri (Siniperca kneri) are both Perciformes, Siniperidae, Siniperidae, and Siniperca genus fishes. The optimum temperature for life is 7°C-32°C, and the optimum temperature is 18°C-25°C It is a ferocious freshwater bottom-dwelling fish in the order Perciformes. The mandarin fish is distributed from low-latitude Vietnam through central Yunnan to Sichuan to the east of the Qinling Mountains, across the Yellow River to the Heilongjiang River Basin in Northeast China, and extends eastward to ...
