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 a cultivation method of deep-sea scallops. Atlantic deep-sea scallop breeding and breeding methods, including the introduction of deep-sea scallops and the artificial breeding and cultivation of deep-sea scallops. After 45-50 days, the broodstock reaches maturity and spawns. When most of the larvae have developed to D-shaped After the larvae, the larvae are selected and cultivated in a new pond with a screen box; the growth rate of the cultivated larvae is much higher than that of the larvae cultivated in the nursery in Quebec, Canada during the same period, and most of the larvae appear eyespots 16-17 days after fertilization. On the 18th day, the attachment base was cast. After 10 days of the attachment base, the attachment base was taken out and hung in the sea area to preserve the seedlings in the natural sea area to preserve the seedlings; the deep-sea scallops reached a commercial size with an average size of more than 8 cm and reached sexual maturity. The invention successfully introduces Atlantic deep-sea scallops into Chinese sea area for the first time, expands the species of scallops cultured, and promotes the construction of modern marine pastures.

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...
