Embodiment 1

[0040] The method for breeding and increasing culture of Atlantic deep-sea scallops comprises the following steps:

[0041] The first step, the introduction of deep-sea scallops:

[0042] 300 kg of deep-sea scallop species were transported by air from Halifax, Nova Scotia, Canada to Qingdao Airport in April 2008, which took about 33.5 hours. Immediately upon arrival, they were transported to the isolation farm in Zhaike, Jiaonan for 30 days. After passing the inspection and quarantine, they were airlifted to Dalian Airport, and then transported to Haiyang Island by ship, where they were temporarily kept in the sea. The average shell height of this batch of deep-sea scallop species was 8.65±0.68 cm, the average weight was 86.7±0.7 g (N=30), and the survival rate was about 66.8%.

[0043] The second step: artificial breeding and breeding of deep-sea scallops

[0044] (1) Parenting to promote ripening:

[0045] The male and female broodstock are separated and placed in differe...

Abstract

The invention relates to an aquaculture method of deep sea scallops, in particular to a breeding and propagation method for Atlantic deep sea scallops. The method comprises the steps that introduction, artificial breeding and aquaculture of the deep sea scallops are carried out, parent scallops are mature after 45-50 days maturity promoting and lay eggs, and after most larvae grow into D-shaped larvae, a bolting cloth net cage is used for selecting optimal larvae to a new pond for cultivation; the growth rate of the cultured larvae is far higher than that of the larvae cultured in a nursery ground in Quebec of Canada at the same time, eyespots are generated on most larvae 16-17 days after the larvae are fertilized, adhering substances are arranged at the 18th day, after the adhering substances are arranged for 10 days, the adhering substances are taken out and hung in natural sea ears for larva protection; the deep sea scallops meet commercial specification when the cultivated average specification reaches 8 centimeters, and the deep sea scallops achieve sexual maturity. According to the method, the Atlantic deep sea scallops are introduced into China sea areas for the first time, the scallop culture species are expanded, and construction of modern ocean ranches is promoted.

Description

technical field [0001] The invention relates to a method for cultivating marine products, in particular to a method for cultivating deep-sea scallops. Background technique [0002] At present, there is only one kind of large scallop cultured in the northern seas of my country, the Ezo scallop. Because of its large size and delicious taste, Ezo scallop has become the main scallop species consumed by high-end hotels and is very popular in the market. In recent years, the high mortality rate in scallop farming has made the supply of products not stable enough, and the irregular edges of scallops make them easy to lose moisture, so the shelf life is short, and a single species cannot meet the diversification of the market need. Therefore, the scallop farming industry needs more large-sized scallops with good taste, long shelf life and stable supply to support its sustainable development. [0003] Atlantic deep-sea scallops ( Placopecten magellanicus ) are large scallops nati...
