Abstract

A bay scallop cultivation method comprises the following steps: (1) culturing on the sea; (2) cultivating in a net cage; (3) moving the seeds into a cage for cultivation; (4) and (6) harvesting. The culture method of bay scallops strictly controls culture conditions and parameters in each link of culture, thereby realizing the rapid growth of the scallop seedlings, ensuring the meat quality and improving the yield of the bay scallops.

Description

A kind of culture method of gulf scallop

technical field

The invention relates to the technical field of marine product cultivation.

Background technique

Bay scallops belong to the class Phalalobranches, Heterocylinda, Scallopidae, Scallop genus, also known as Atlantic Bay scallops. Native to the east coast of the United States. It was introduced into China by Zhang Fusui in 1982, and artificial breeding was carried out. The current annual output is about 80,000 tons, mainly concentrated in Shandong and Liaoning.

The processing and utilization rate of bay scallops is very high, and almost the whole body is full of treasures. Its adductor muscle can be processed into frozen fresh column and canned food. The mantle of scallops can be processed into shell edges, which can be eaten or used as fresh bait for fish and shrimp. The two shells of scallops can be used as the attachment base for shellfish seedlings, and are also indispensable raw materials for the shell carving industry.

Bay scallops have the characteristics of fast growth and short production cycle. Due to the particularity of the climate in northern coastal cultured oysters, how to improve the growth rate, yield, and meat quality of bay scallops on the basis of traditional oyster farming methods is a subject of continuous research. topic.

Contents of the invention

In order to improve the yield, meat quality and growth speed of bay scallop culture, the invention provides a culture method of bay scallop.

The technical solution adopted by the present invention for achieving the above object is: a culture method of bay scallops, comprising the following steps:

(1), cultivation at sea: commercial seedlings of 3-5 mm, after 3-5 days of temporary cultivation, then divide the seedlings, and then divide them into net cages and cultivate them at sea for 10-15 days;

(2), net cage is cultivated, reaches more than 1 centimeter, is transferred to the net cage that mesh is 0.8-1.0 centimetre, continues to cultivate;

(3) Move it into a cage for growth, when the shell height reaches 2-2.5 cm, it can be moved into a growth cage for growth. The water temperature is -2-30°C, the salinity is 20-30‰, and the transparency is more than 50 cm;

(4), harvesting, after about 90-120 days in the growing cage, the shell height has reached more than 5 cm, and the harvesting season can be entered.

In the described step (1), the meshes are divided into 18 mesh or 16 mesh cages.

In the described step (2), there are 10-110,000 scallop seedlings per mu, 350-450 breeding net cages are set per mu, and 8-12 layers are established for each net cage.

In the step (4), the harvesting ends before the water temperature in the sea area drops to 5°C.

The method for cultivating bay scallops of the present invention realizes rapid growth of shellfish seedlings, ensures meat quality, and improves yield of bay scallops by strictly controlling culture conditions and various parameters in each link of cultivation.

Detailed ways

The cultivation method of bay scallop of the present invention comprises the following steps:

(1), cultivate at sea: the commodity seedling of 3-5 millimeter, through 5 days temporary support, carry out the seedling division again then, be divided into mesh and be in 18 mesh cages, cultivate through the sea of 15 days;

(2), net cage is cultivated, reaches more than 1 centimetre, is transferred to the net mesh that mesh is 0.8 centimetres, and continues to cultivate, and every mu shellfish seedling 100,000, every mu is provided with 400 breeding net cages, and each net cage is established 10 Floor;

(3) Move it into a cage for growth, and when the shell height reaches 2 cm, it can be moved into a growth cage for growth. The water temperature is -2-30°C, the salinity is 20-30‰, and the transparency is more than 50 cm;

(4), harvest, after about 90-120 days in the growing cage, the shell height has reached more than 5 cm, and the harvest season can be entered. Before the water temperature in the sea area drops to 5°C, the harvest ends.

The present invention has been described by means of embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, the features and examples may be modified to adapt a particular situation and material to the teachings of the invention without departing from the spirit and scope of the invention. Therefore, the present invention is not limited by the specific embodiments disclosed here, and all embodiments falling within the scope of the claims of the present application belong to the protection scope of the present invention.
