Cross breeding method for improving growth traits of slender mandarinfish

Abstract

The invention discloses a cross breeding method for improving growth traits of slender mandarinfish. The cross breeding method can be widely applied in large-scale breeding and belongs to the field of agricultural technology which is necessary for human life. The cross breeding method comprises the following main steps of parent fish cultivating, artificial inseminating, fish seed cultivating, cultivating in a pool, etc. Mandarin fish is selected as female parent fish and the slender mandarinfish is selected as male parent fish and furthermore intensive cultivation is performed. Artificial propagation technical measures of hasten parturition according to a male-and-female synchronous one-time exogenous hormone injection method, artificial dry-method inseminating, circular-channel water-flow hatching, etc., fish seeds are hatched. A segmented cultivation mode is adopted. High-palatability fish bait is applied. Furthermore breeding management in a seed period and a mature period are reinforced. The invention provides the method for improving the growth traits of the slender mandarinfish. The shape of the crossbred slender mandarinfish which is generated according to the method is different from that of the male parent fish and that of the female parent fish, and furthermore the growth advantage is better than that of the male parent fish. Furthermore the crossbred slender mandarinfish has advantages of high meat quality, delicious taste, high disease resistance, high growing speed, capability of eating dead fish, etc. The crossbred slender mandarinfish is a novel breed of the crossbred mandarin fish which facilitates artificial large-scale breeding.

Description

technical field [0001] The invention belongs to the technical field of fish breeding and reproduction, and in particular relates to a method for producing a new species of long-skinned mandarin fish with obvious morphological characteristics and growth advantages by using the cross-breeding technology between fish species. It can be widely used in family and collective mandarin fish farming, especially large-scale breeding. Background technique [0002] Sinipercaroulei and Sinipercachuatsi belong to the order Perciformes, and both Siniperidae and Siniperca are high-grade freshwater aquatic species. Long-body mandarin fish is a species of wild mandarin fish, also known as long-body mandarin fish, also known as bamboo-tube mandarin fish, colorful mandarin fish, and colorful osmanthus. Long body mandarin fish is a specialty fish in eastern my country, widely distributed in the waters of Zhejiang, Fujian, Jiangxi, Hunan, Guizhou and Guangxi in the south of the Yangtze River. C...
