Embodiment 1

[0007] Select a mud-sand seabed with a water depth of 4-5 meters and a water temperature of 18°C, and take a mud-sand sample for testing: according to the weight ratio of mud 60% and sand 40%, put cockle juveniles with a body length of 0.74-1.13cm on the mud-sand seabed, bottom sow Density 30 grains / m 2 .

Embodiment 2

[0009] Select a mud-sand seabed with a water depth of 5-6 meters and a water temperature of 10°C, and take a mud-sand sample for testing: according to the weight ratio of 80% mud and 20% sand, put cockle juveniles with a body length of 0.74-1.13cm on the mud-sand seabed. Seeding density 50 grains / m 2 .

Embodiment 3

[0011] Select a mud-sand seabed with a water depth of 4.5-5.5 meters and a water temperature of 15°C, and take a mud-sand sample for testing: according to the weight ratio of 70% mud and 30% sand, put cockle juveniles with a body length of 0.74-1.13cm on the mud-sand seabed. Bottom sowing density 40 grains / m 2 .

[0012] The bottom sowing method of the clam juvenile shellfish is through the bottom sowing test, which is as follows:

[0013] 1. Bottom seeding density in sea area

[0014] On October 31, 2007, 10 plastic baskets were used in the sea-blocking reservoir of Jinzhou Seawater Breeding Center, each with a size of 0.55×0.35×0.15 meters and a bottom area of ​​0.2m 2 10cm medium thickness of sand, according to the weight ratio of 70% and 30% of the mud in the sand, the body length of juvenile shellfish is 0.74-1.13mm, with an average of 0.94mm, and the density of each box is 20, 40, 50, 60, 70 grains / m 2 . It was put into the seabed and observed on October 10, 2008.

Abstract

The invention relates to a bottom sowing method for Scapharca subcrenata juveniles. The method selects the muddy sand seabed with water depth between 4 and 6 meters and water temperature between 10 and 18 DEG C; the Scapharca subcrenata juveniles are put into the muddy sand according to the ratio that mud is between 60 and 80 percent, and sand is between 40 and 20 percent seabed; and the bottom density is between 30 and 50 particles/m<2>. The method solves the problem of exhaustion of resources caused by random fishing when Scapharca subcrenatas grow in natural environment, can ensure that the Scapharca subcrenata juveniles grow quickly in natural environment and meet commercial specification within two years, so that wide consumers can enjoy the flavor of the Scapharca subcrenata.

Description

technical field [0001] The invention relates to an artificial cultivation method of cockles, in particular to a bottom sowing method of cockle juveniles. Background technique [0002] Hair clam (Scapharca suberenata) is more and more favored by consumers at home and abroad because of its delicious meat and rich nutrition. Cockles grow in the natural environment, and resources are exhausted due to disorderly fishing. With the rapid development of artificial breeding in shallow seas, the artificial breeding of cockles has been successful. How to make them grow rapidly in the natural environment is an urgent problem to be solved at present. Contents of the invention [0003] The purpose of the present invention is to provide a method of artificial bottom sowing of cockles, so that young cockles can grow rapidly in the natural environment and reach the commercial specification within two years. [0004] The technical solution of the present invention is: select the silt-sand...
