Embodiment 1

[0017] A new method for cultivating clams in shallow sea hanging cages is carried out according to the following cultivation steps:

[0018] 1) Seed selection: The cockle seedlings bred in that year are used for temporary cultivation in the sea area until November, the shell length reaches more than 0.8cm, and the seedlings are robust and uniform;

[0019] 2) Equipment preparation: Breeding equipment includes two types of breeding cages: temporary cages and growing cages, all of which use scallop cages or re-customized new cages similar in structure to scallop cages. The breeding cages have 10 layers built in with a layer spacing of 12cm 1. A polyethylene disc with a diameter of 30cm. The disc of the temporary cage has a hole with a diameter of 0.5cm, and the disc of the growing cage has a hole with a diameter of 1cm; the culture raft is a scallop culture. The cage is hung on the parallel raft frame, on which there is a float, and the floater and the raft frame are connected b...

Embodiment 2

[0026] A new method for cultivating clams in shallow sea hanging cages is carried out according to the following cultivation steps:

[0027] 1) Seed selection: use cockle seedlings bred in the same year and with a shell length of more than 0.8cm as seedlings;

[0028] 2) Equipment preparation: The breeding equipment includes two types of breeding cages: temporary cages and growing cages, all of which use scallop cages or re-customized new cages similar in structure to scallop cages. The breeding cages are built with 15 layers, and the layer spacing is 18cm 1. Diameter is the polyethylene disc of 34cm, has the hole of aperture 0.8cm on the disk of holding cage temporarily, has the hole of aperture 1.5cm on the disk of grow-up cage; The culture raft frame is the raft frame for scallop cultivation, The breeding cage is hung on the parallel raft frame, and the raft frame is provided with a float, and the floater and the raft frame are connected with a floating rope, and the distan...

Embodiment 3

[0035] A new method for cultivating clams in shallow sea hanging cages is carried out according to the following cultivation steps:

[0036] 1. Seed selection: The cockle seed is the self-propagating seed of Changdao Multiplication Experiment Station in Shandong Province. It spawned on June 20, 2012, and was released from the pond on August 10, 2012. The temporary breeding ended on November 15, with an average size of 1.1. cm, a total of 8 million grains.

[0037] 2. Breeding facilities: The culture cage is a clam scallop culture cage, which is divided into two specifications: temporary culture cage and growth cage. The culture cage is built with 10-15 layers, the layer spacing is 12-18cm, and the diameter is 30-34cm. Vinyl discs, holes with a diameter of 0.5-0.8 cm are opened on the discs of the temporary cages, and holes with a diameter of 1-1.5 cm are opened on the discs of the growing cages;

[0038] 3. Breeding process

[0039] 1) Caged on November 15, 2012, 900 seedlin...

Abstract

The invention relates to an ecological, intensive and health culture method about Arca inflata Reeve. A novel shallow sea suspension cage culture method of Arca inflata Reeve is characterized by comprising the following steps: (1) seedling selection; (2) equipment preparation; (3) seedling dropping; (4) first cage pouring; (5) second cage pouring; (6) third cage pouring; and (7) Arca inflata Reeve growing. According to the novel shallow sea suspension cage culture method of Arca inflata Reeve disclosed by the invention, raft culture is carried out on original buried shellfish, so that the intensification level is improved, the culture benefit is guaranteed, the method is ecological and environment-friendly above all, and a positive cycle is provided for the ecological balance for oceans.

Description

technical field [0001] The invention relates to aquaculture technology, which is an ecological and healthy cultivation technology of shellfish, in particular a technical method related to the ecological, intensive and healthy cultivation of cockles. Background technique [0002] clam ( Scapharca broughttonii Schrenck), commonly known as red clams and big hairy clams, is a large bivalve mollusk that lives in camps. It lives on muddy or muddy seabeds with a water depth of 3 meters near the shore to nearly 50 meters in the open sea. It is widely distributed in the Northwest Pacific Ocean. Sea of ​​Japan, 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, and 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 high quality. Clam meat is delicious, nutritious, and of high economic value. It is a mar...
