Problems solved by technology

[0005] The purpose of the present invention is to establish a stable and mature polyculture of cockles and scallops by establishing the technical points such as the specification and time of entering the cage, the proportion of the two, the time of inverted cage and harvesting when the cockles and scallops are mixed. On the one hand, it solves the problems of low level of intensification, low survival rate, and great damage to the environment caused by natural harvesting of clams, and at the same time improves the survival rate of clams in cages; on the other hand, it solves the problem of clams Solve the problems of single farming mode, unstable and low farming benefits, improve the overall benefits of shellfish farming, and promote the development of shellfish industry

Embodiment 1

[0021] A new method for mixed cultivation of cockles and scallops in shallow sea hanging cages is carried out according to the following cultivation steps:

[0022] 1) Seed selection: Clam cockle seedlings are artificially bred and have a shell length of more than 0.8 cm; Chlamys farreri seedlings are artificially bred or naturally harvested seedlings, and the shell length is more than 0.6 cm;

[0023] 2) Equipment preparation: including temporary cages and growing cages, using scallop cages or re-customizing new cages similar in structure to scallop cages;

[0024] 3) Throwing seedlings: from the end of October to the beginning of November, when the water temperature drops below 15°C, put the clam seedlings and cleft scallop seedlings into temporary cages for overwintering, with a layer capacity of 800 pieces. Stock them in seawater at a depth of 6m, and hang them on floating rafts at intervals of 70-90cm;

[0025] 4) One-time cage inversion: In April of the following year, ...

Embodiment 2

[0030] 1) Seed selection: Clam cockle seedlings are artificially bred and have a shell length of more than 0.8 cm; Chlamys farreri seedlings are artificially bred or naturally harvested seedlings, and the shell length is more than 0.6 cm;

[0031] 2) Equipment preparation: including temporary cages and growing cages, using scallop cages or re-customizing new cages similar in structure to scallop cages;

[0032] 3) Throwing seedlings: from the end of October to the beginning of November, when the water temperature drops below 15°C, put the cockles seedlings and scallop seedlings into temporary cages respectively, and keep them separately for overwintering, with a layer capacity of 1000. Place temporary cages in 8m deep seawater and hang them on floating rafts at intervals of 70-90cm;

[0033] 4) One-time cage inversion: In April of the following year, cage inverting is performed when the water temperature rises above 10°C. Clean up the cockle seedlings and scallop seedlings fr...

Embodiment 3

[0038] 1) Selection of seedlings: the seedlings of cockles are self-propagating seedlings of the Changdao Multiplication Experimental Station. They spawned on June 20, 2013, and were released from the pool on August 10th for temporary cultivation. The temporary cultivation ended on November 15th, with an average size of 0.9 cm, a total of 10 million grains; Chlamys farreri seedlings are self-propagating seedlings from the Long Island Multiplication Experiment Station, spawned on May 11, 2013, were released from the pond on June 15, and were temporarily raised on October 15. The average size 1.1cm, 10 million grains in total;

[0039] 2) Breeding facilities: the culture cages are Chlamys farreri culture cages, which are divided into 2 specifications: temporary cages and grow-out cages;

[0040] 3) Throwing seedlings: On November 8, 2013, when the water temperature dropped below 15°C, put the cockles seedlings and scallop seedlings into temporary cages for overwintering culture,...

Abstract

The invention relates to an ecological, intensive and healthy culture method for scapharca broughtonii and chlamys farreri. The novel shallow sea cage mixed-culture method for scapharca broughtonii and chlamys farreri is characterized by comprising the following first culture step of fry selection, the second culture step of device preparation, the third culture step of fry casting, the fourth culture step of first-time cage overturning, the fifth culture step of second-time cage overturning, the sixth culture step of third-time cage overturning and the seventh culture step of adult scapharca broughtonii and adult chlamys farreri obtaining. By means of the novel shallow sea cage mixed-culture method for scapharca broughtonii and chlamys farreri, original bottom-dwelling scapharca broughtonii is cultured in cages, so that the intensification level of culture is increased, the problems that the death rate in scapharca broughtonii cage culture is high and the culture benefit of chlamys farreri is low are solved, and the comprehensive culture benefit is increased.

Description

technical field [0001] The invention relates to aquaculture technology, which is an ecologically healthy culture technology for shellfish, in particular to a new ecological, intensive and healthy culture method of co-culturing cockles and scallops. Background technique [0002] Scapharca broughttonii Schrenck is a large bivalve mollusk that lives in camps. It lives on muddy or muddy seabeds from a depth of 3 meters near the shore to nearly 50 meters offshore. It is widely distributed in the Sea of ​​Japan in the northwest Pacific Ocean. , Yellow Sea, Bohai Sea, East China Sea, my country's Liaodong Peninsula, Shandong Peninsula and the coast of the East China Sea are rich in resources. The resources of clams in the northern part of the Yellow Sea are the most concentrated, and they are famous for their large output and good quality. Clam meat is delicious, nutritious, and of high economic value. It is a marine treasure. Frozen ark shell meat is very popular in the internation...
