Embodiment 1

[0017] A kind of clam shallow sea hanging cage cultivation method 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. A polyethylene disc with a diameter of 30 cm, holes with a diameter of 0.5 cm are provided on the disc of the temporary cage, and holes with a diameter of 1 cm are provided on the disc of the growing cage; Hanging on the parallel raft frame, there is a float on the raft frame, the floater and the raft frame are connected by a floating rope, and the distance between the raft frames is 8 meters;

[0020] 3) In November,...

Embodiment 2

[0026] A kind of clam shallow sea hanging cage cultivation method 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: 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 15 layers inside, with a layer spacing of 18cm A polyethylene disc with a diameter of 34cm, holes with a diameter of 0.8cm are arranged on the disk of the temporary cage, and holes with a diameter of 1.5cm are arranged on the disk of the growing cage; The cage is hung on a parallel raft frame, on which there is a float, and the floater and the raft frame are connected by a floating rope, and the distance between the raft frames is 10 meters;

[0029] 3) In November, when the water t...

Embodiment 3

[0035] A kind of clam shallow sea hanging cage cultivation method 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: a temporary culture cage and a grow-out 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 seedli...

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...
