Benefits of technology

This patented technology allows for creating an organism called Daphne reservoirs (Danija), which can be used both with or without females. These two parents have different characteristics - one being better than another but less expensive compared to other forms like turtles' eggs. They produce seeds made up mostly of tiny pigmented spikes on their skin when they mature quickly enough.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the quality and quantity of seafood by reducing its consumption while maintaining their taste or smell (the flavor) at an acceptable level.

Embodiment Construction

[0021] refer to figure 1 As shown, a method of distant hybridization breeding between red-tailed red bream and black-tailed red-tailed red-tailed bream. As the male parent, the hybrid generation was bred through distant hybridization, and the hybrid "Pioneer No. 1" was bred with this hybrid combination. The species of geographical indication in my country—Red bream in Danjiangkou Reservoir has the characteristics of relatively docile temperament and mature eggs are drifting eggs. The hybrid "Pioneer No. 1", which was bred from the Danjiangkou Reservoir's "Pioneer No. 1" with the female parent of the red catfish and the black-tailed catfish in the upper reaches of the Yangtze River, could not reproduce naturally in still water.

[0022] It is determined to use the red chrysalis in the Danjiangkou Reservoir as the female parent to breed the hybrid "Pioneer No. 1", which not only has the advantages of good shape and large size of the red chrysalis, but also has the advantages of...

Abstract

The invention discloses a breeding method for distant hybridization between erythroculter ilishaeformis and ancherythropterus nigrocauda. The method includes the following steps: 1) selecting selectively-bred erythroculter ilishaeformis and selectively-bred ancherythropterus nigrocauda as parents; 2) conducting parents strengthening breeding including erythroculter ilishaeformis strengthening breeding and ancherythropterus nigrocauda strengthening breeding; 3) conducting artificial spawning induction: respectively injecting spawning induction medicine hypophysis cerebri or dopamine antagonist DOM, lutein releasing hormone analogue and chorionic gonadotropin which are used singly or in mixing mode on the two parents; 4) conducting artificial semen and spawn collection and insemination including dry method insemination and semi-dry method insemination; and 5) conducting artificial incubation. Hybridized culter 'vanguard 1' obtained by distant hybridization has the advantages of good body type and large size of the erythroculter ilishaeformis, also has the advantages of low breeding cost, mild temper, easiness in catching and easiness in live marketing of the ancherythropterus nigrocauda and further has excellent hybridization performances like high growing speed.
