Embodiment 1

[0018] 1. Select 2-year-old shellfish with mature and healthy gonads with a shell length of 6cm (the surface of the shell is fresh, complete, undamaged, and full of gonads), clean it, remove barnacles and oysters on the surface of the shell with a knife, and put it in The cages in the pool were intensively cultured for 10 days.

[0019] 2. Rinse the cockles that have been intensively cultivated with sand-filtered seawater, dry them in the shade for 10 hours, sterilize them with potassium permanganate solution, and then stimulate them with running water for 2 hours to induce labor; put the brood clams to be laid in the spawning pool for For spawning, the spawning density is controlled at 120 grains / mL. During the spawning process, the water is stirred to increase the fertilization rate of the eggs, and remove the excess viscous foam; after the spawning, quickly remove the spawning brood, and dilute the fertilized eggs in time , after filling up the pool with water and resting f...

Embodiment 2

[0023] 1. Select 3-year-old brood shellfish with mature and healthy gonads with a shell length of 7cm (the surface of the shell is fresh, complete, undamaged, and full of gonads), clean it, remove barnacles and oysters on the surface of the shell with a knife, and put it in The cages in the pool were intensively cultured for 13 days.

[0024] 2. Rinse the cockles that have been intensively cultivated with sand-filtered seawater, dry them in the shade for 8 hours, sterilize them with potassium permanganate solution, and then stimulate them with running water for 1 hour to induce labor; put the cockles to be produced into the spawning pool for Oviposition, the density of oviposition is controlled at 130 grains / mL, and the water is stirred during the oviposition process to increase the fertilization rate of the oocytes and remove excess viscous foam; after oviposition is over, quickly remove the oviposition broodstock to dilute the fertilized oocytes in time After filling up the ...

Embodiment 3

[0028] 1. Select 3-year-old brood shellfish with mature and healthy gonads with a shell length of 8cm (the shell surface is fresh, complete, undamaged, and full of gonads), clean it and remove the barnacles and oysters on the surface of the shell with a knife, and put it in The cages in the pool were intensively cultured for 15 days.

[0029] 2. Rinse the cockles that have been intensively cultivated with sand-filtered seawater, dry them in the shade for 10 hours, sterilize them with potassium permanganate solution, and then stimulate them with running water for 2 hours to induce labor; put the brood clams to be laid in the spawning pool for For spawning, the spawning density is controlled at 150 grains / mL. During the spawning process, the water is stirred to increase the fertilization rate of the eggs and remove the excess viscous foam; after the spawning is over, quickly remove the spawning brood and dilute the fertilized eggs in time , after filling up the pool with water a...

Abstract

The invention relates to a culturing technique for clam shells, in particular to a factory culturing method for clam shells, wherein the method comprises the following steps: selecting healthy breeder shells of which sexual glands are matured to perform enrichment culture, then hastening parturition; after the oviposition, removing the breeder clam shells, and thinning the oosperms; when the D-shaped larva hatched from the oosperms closely gather on the water surface, selecting the excellently developed D-shaped larva to put into a culturing pool and culturing into juvenile shells, then adding an adherence; continuously culturing the juvenile shells adhered on an adhering machine until the shell is more than 600 microns in length; and moving the juvenile shells and the adherence to a shrimp pool or the sea for intermediate culture. The process flow is simple, the maneuverability is high and the technique is stable, so that the clam shell can naturally spawn and be fertilized; moreover, the rates of fertilizing and hatching are high; therefore, the problem of the quantity production of the clam shells are effectively solved, and full-artificial factory culture of the clam shells can be realized; and moreover, the method has low cost, fast affecting and great benefits, thereby laying the foundation for the large-scale artifical culture of the clam shells.

Description

technical field [0001] The invention relates to a shellfish seedling raising process, in particular to a method for industrialized seedling raising of ancient cockles. Background technique [0002] Ancient cockles, also known as ancient hairy cockles, are a kind of cockles of the cockle family. They are mainly distributed in the waters around Singapore, Indonesia, Taiwan and Hainan Province. They are common economic shellfish in Hainan. Ancient cockles are filter-feeding shellfish, and their bait organisms are mainly single-celled algae. Mixing with other species can reduce the content of ammonia, nitrogen, and nitrite in the water, purify the water quality, and stabilize the pH value. Its blood contains Heme, red in color, rich in flavor and delicious, has the characteristics of high protein, low fat, high vitamin content, etc., and has medicinal value, and is deeply loved by consumers. In recent years, due to overharvesting and depletion of natural resources, the price of...
