Embodiment Construction

[0025] The peak breeding period of Cujiangyao is generally in July, and it takes more than 20 days to cultivate the larvae of Cujiangyao, and the water temperature is high, the bait is not easy to cultivate, and it is difficult to raise seedlings. In view of this actual situation, early seedlings are raised, and broodlings are put into the pond early. Promote maturation.

[0026] Before the broodstock is cultivated to promote ripening, the attached organisms on the surface of the brockard shells are removed, washed and then put into the pool, and floating cages are used to promote the ripening of the broccoli. Generally, 2 to 4-year-old adult shellfish with a shell length of more than 18 cm, a healthy body, no trauma to the shell, and good gonad development are selected as broodstock.

[0027] 1. The baby raising period

[0028] Water temperature: stable for 5 days after entering the pool, the water temperature is 15°C when entering the pool, and then rises to 22°C at a rate ...

Abstract

The invention aims at providing a method for breeding Pinna (Atriina) pectinata Linnaeus. The method comprises the following steps of: selecting the Pinna (Atriina) pectinata Linnaeus as a parent shellfish, accelerating the ripening of the Pinna (Atriina) pectinata Linnaeus so the parent shellfish gradually matures; drying the parent shellfish in the shadow, radiating the parent shellfish for 3 hours with a 30W ultraviolet lamp to ensure that the mature parent shellfish leaves sperms and ova which are subjected to fertilization in water and develop into a D-shaped veliger larva in 25 hours after fertilization; collecting the D-shaped veliger larva by a 300-mesh trawl when the larva is developed into the D-shaped veliger larva, breeding the D-shaped veliger larva in a breeding pond; throwing larva collection bags to collect the larva when the larva has legs; rinsing juvenile mollusk, and overturning the larva collection bags, strewing the juvenile mollusk to the other pond spread with sands, wherein the food organism attached by the juvenile mollusk is tetraselmis and pyramimonas sp.

Description

Technical field: [0001] The invention relates to a seedling raising method, in particular to a Kujiangyao artificial seedling raising method. Background technique: [0002] Pinna (Atriina) pectinata Linnaeus is a seafood shellfish with high economic value. The meat is tender, fat and white, and rich in nutrition. seafood treasures. Fresh shellfish and "Jiang Yaozhu" are not only available for the domestic market, but also can be exported to earn foreign exchange. [0003] Cujiangyao generally reach sexual maturity in 2 to 3 years, the reproductive cycle is 1 year, and the gonads mature once every year. In a reproductive cycle, there are four stages in the development of gonads: formation, proliferation, mature discharge and rest. The breeding season is from May to November, and the optimum temperature for spawning is 24°C to 27°C. The appearance of the gonads of Kujiangyao is difficult to distinguish, and the male and female gonads can be distinguished in color until the...
