Embodiment Construction

[0005] Concrete method and steps of the present invention:

[0006] 1) Time selection of Chlamys farreri seed breeding and autumn seedling preparation usually start from mid-August to September in autumn, and make preparations for breeding in advance, such as seedling equipment preparation and cleaning, disinfection and personnel Division of labor, reproduction of algal species, etc.

[0007] 2) Screening and temporary raising of broodstock for the breeding of Chlamys farreri seedlings is to select healthy broodstocks with well-developed gonads in mid-to-late August, clean them, and select male and female separately into the pond for temporary breeding. The stocking density should be controlled below 30-50 per cubic water body. It can be suspended in cages or floating rafts for temporary storage. Aerated properly, running water or changing the water 1-2 times a day, and feeding flat algae, For golden algae or other particulate artificial baits, it is necessary to frequently r...

Abstract

The invention relates to the method for Pinna pectinate autumn offspring breeding and pruning, which comprises, selecting August to September for offspring breeding, choosing the eligible parent shellfish, after 10-15 days, regulating the parent shellfish sex gland to synchronous ripening, carrying out oviposition and fertilization, and carrying out scallop larva incubation, after 13-18 days, adhering the larva to juvenile mollusk through metamorphosis, cultivating the juvenile mollusk temporarily for 10-15 days, then carrying out seedlings protectoin on the sea, breeding on the sea in November, and harvesting during September to November in the next year till the July of the third year.

Description

technical field [0001] The invention relates to an aquaculture technology, in particular to a method for breeding and growing scallops in autumn. Background technique [0002] At present, the artificially cultivated Chlamys farreri is seeded in spring (March-May). Generally, sea scallops are temporarily raised and seedlings are kept in May-October, and seedlings are grown in October-November or March of the next year. Under normal circumstances, it will be harvested after October of the second year. Since 1996, due to large-scale diseases, most of them were harvested before August. This spring breeding mode of Chlamys farreri has many disadvantages. In the Yellow and Bohai Sea regions, the water temperature is very low from March to May, and the seedlings need to be heated by boilers to ensure the temperature of the seedling water body, so a lot of energy is consumed and the cost is increased; especially for scallops. The seedlings enter the high temperature period soon af...
