Embodiment 1

[0020] The philippine clam spats with a shell length of 0.4mm that have been bred in the early stage are transferred to mesh bags with a mesh of 0.2mm, and 6,000 spats are placed in each bag; 6 mesh bags are combined into 1 bundle, and 10 bundles are bundled into 1 Hanging, each bundle is connected by a sling, each bundle is 15cm apart, and the length of the sling is 3m; one end of the sling is tied to the floating raft, and the other end is tied to a falling stone or sandbag, so that the sling hangs on the floating raft Below, the weight of the falling stone or sandbag is 1.0kg. The distance between the net bag and the big rope is 1.0m, and the distance between the net bag and the seabed is controlled by changing the length of the sling, and the distance between the slings is 1.0m as long as the falling stone does not touch the seabed during the spring tide and low tide.

Embodiment 2

[0030] After the intermediate breeding in the early stage, the Philippine clam spat with a shell length of 0.4mm is transferred into a mesh bag with a mesh of 0.1mm, and 7,500 spat are placed in each bag; 6 mesh bags are integrated into 1 bundle, and 10 bundles are integrated into 1 sling , each bundle is connected by a sling, the distance between each bundle is 15cm, and the length of the sling is 4m; one end of the sling is tied to the floating raft, and the other end is tied to a falling stone or sandbag, so that the sling hangs on the floating raft. Next, the weight of the falling stone or sandbag is 1.0kg. The distance between the net bag and the big rope is 1.0m; the distance between the net bag and the seabed is controlled by changing the length of the sling, and the distance between the slings is 1.0m as long as the falling rock does not touch the seabed during the spring tide and low tide.

Embodiment 3

[0037] After the intermediate breeding in the early stage, the Philippine clam spat with a shell length of 0.4mm is transferred into a mesh bag with a mesh of 0.1mm, and 9,000 spat are placed in each bag; 7 mesh bags are integrated into 1 bundle, and 10 bundles are integrated into 1 sling , each bundle is connected by a sling, the distance between each bundle is 16cm, and the length of the sling is 5m; one end of the sling is tied to the floating raft, and the other end is tied to a falling stone or sandbag, so that the sling hangs on the floating raft. Next, the weight of the falling stone or sandbag is 1.0kg. The distance between the net bag and the paddle is 1.1m; the distance between the net bag and the seabed is controlled by changing the length of the sling, and the distance between the slings is 1.1m as long as the falling stone does not touch the seabed during high tide and low tide.

Abstract

It relates to an method of intermediate rearing mussel germchits during later period in shallows. When the germchits are cultivated during later period at natural cultivating sea zones, the germchitsare cultivated in string bags, and hanged at buoyant rafts and cultivated. The method comprises: transferring juvenile mollusks with the 0.4??.5mm shells in length into string bags, 5,000í½11,000 juvenile mollusks in a string bag, assembling 6í½10 bags into a bundle, assembling 10-15 bundles into a string, the distance between strings is 15í½30cm; the distance between the string ropes is 1.0í½1.5mú

Description

technical field [0001] The present invention relates to the late stage intermediate breeding technology of tidal flat shellfish, especially provides a kind of late stage intermediate breeding method suitable for tidal flat shellfish such as Philippine clams, which is to hold juvenile shellfish in net bags in natural sea area and hang them on floating Raft, to achieve efficient and safe late intermediate breeding. Background technique [0002] Intermediate breeding technology is an important technical link in the artificial breeding technology of tidal flat shellfish such as Philippine clams. Philippine clam Ruditapes philippinarum (Adams et Reeve) is a species distributed worldwide, and it is distributed in coastal waters from south to north in China. Adults over 2 years old have a shell length of 2.5-4.5 cm. The shell is oval and swollen. The left and right shells are equal. The shell surface has relatively smooth concentric growth lines centered on the top of the shell. ...
