But present existing hybridized prussian carp also exists certain weak point: 1, the genetic character of filial generation is stable inadequately; 2, not high enough to the sporozoit resistance; 3, growth rate is fast inadequately; 4, still exist higher lethality in the long-distance transport process.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, a kind of optimal seedling selection and breeding of novel carassius auratus gibelio series method is provided.
Optimal seedling selection and breeding of novel carassius auratus gibelio series method of the present invention comprises the following steps:
(1) extracts upright pond crucian carp ovum;
(2) extract the red carp sperm of making the country prosperous;
(3) stimulate the reproduction of pond crucian carp ovum gynogenesis to produce the gynoecy offspring with the red carp sperm of making the country prosperous as the allos sperm; In this process, the sperm of the red carp of making the country prosperous only plays inducing action, and its sperm nucleus does not merge mutually with the egg nucleus of upright pond crucian carp, and its filial generation proterties is not separated, and this just very helps go down to posterity breeding and the expansion production of hybridized prussian carp seed.
(4) extract grass carp and megalobrama amblycephala sperm, extract the filial generation ovum in (3) step;
(5) utilize grass carp and megalobrama amblycephala sperm stimulate (3) step in gynogenesis that filial generation is produced, make its filial generation proterties more stable;
(6) fine-variety breeding: adopt the method for colony's seed selection and family selective breeding combination,, intestines length/total length long with body is first and second growth traits, is aided with dorsal muscles thickness, scale elasticity, a plurality of indexs of visceral mass weight and carries out seed selection.
Preferably, in the said fine-variety breeding process, from the shoal of fish, choose individual big, body weight gain than good fish, selection rate is lower than ten thousand/, the fish of selecting is cultured, make its breeding produce fish of future generation.
More preferably, the seed selection algebraically of said fine-variety breeding process was 4 generations.
Optimal seedling selection and breeding of novel carassius auratus gibelio series method of the present invention has following technique effect:
1) can obtain to meet breeding goal, the more stable novel carassius auratus gibelio series of inheritance, set up the novel carassius auratus gibelio series seed selection of a cover standard and protect kind of a technical system, form the complete seedling artificial breeding technology system of a cover;
