Embodiment Construction

[0026] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0027] A method for promoting maturation and spawning of razor shellfish, comprising the following steps:

[0028] (1) Firstly select razor clams with a size of 6-8cm as broilers, and use 100-120 pieces / m 2 Put it in the nursery pond for cultivation, put it in the plastic cage covered with mud and sand in the nursery pond, and carry out the next step of maturation-promoting cultivation; the plastic cage (1) is made of polyethylene plastic and grows into 3 It is a cuboid net cage with a width of 2 meters and a height of 20-30 cm. The bottom and surroundings of the net cage are provided with polyethylene plastic nets (2) with holes smaller than the width and height of razor clams. handle (3); the thickness of the mud and sand laid in the plastic net cage is 8-10cm, the ratio of mud and sand is 7 parts of mud: 3 parts of sand, the mud is sea ...

Abstract

The invention discloses a maturation promoting culture and spawning method for a parent shellfish of cultellus attenuatus. The maturation promoting culture and spawning method comprises the steps: firstly, selecting the parent shellfish of cultellus attenuatus, placing the parent shellfish into a plastic net cage paved with mud and sand in a nursery pond, and carrying out the next-step maturationpromoting culture; feeding a unicellular algae bait during maturation promoting culture, and carrying out maturation promoting culture on the cultellus attenuatus by raising the temperature step by step to make the sexual gland of the parent shellfish matured; determining the spawning time by measuring the wet weight fatness and the thickness of the sexual gland; drying the sexual-gland-matured parent shellfish of the cultellus attenuatus in the shade, soaking the sexual-gland-matured parent shellfish, and carrying out micro-aeration during soaking; then, placing the soaked parent shellfish ofthe cultellus attenuatus into seawater treated by using a bleaching solution to spawn and discharge a seminal fluid; and spawning the parent shellfish of the cultellus attenuatus to achieve a required oosperm, and then, removing the parent shellfish of the cultellus attenuatus to obtain an artificially-cultured oosperm. By using the maturation promoting culture and spawning method, the problem that the indoor artificially-cultured parent shellfish of the cultellus attenuatus is difficult to be subjected to maturation promoting culture and spawning can be solved, the production demands of artificial culture of the cultellus attenuatus is met, and the basis is provided for large-scale production of the cultellus attenuatus.

Description

technical field [0001] The invention relates to a method for artificial breeding of razor clam, in particular to a method for promoting maturation and laying eggs of clam broccoli. Background technique [0002] Clam clam ( Cultellus attenuatus ) belongs to the phylum Mollusca, class Bivalvia, order Veneroida, and family Cultellidae, and lives in shallow seas with a depth of several meters to tens of meters, and its bottom is generally sand At the end of the year, razor clams are distributed in the north and south coasts of my country, and are one of the rare species of shellfish in my country. As a new species of shellfish cultured, razor clam has the characteristics of fast growth, rich nutrition and high price. Therefore, razor clam has high economic value and industrial development prospect. However, with the improvement of fishing technology, the amount of resources of razor clam has gradually decreased, and there is a trend of depletion. The existing output can no long...
