Embodiment 1
[0015] (1) Cultivation of broodstock: In April 2011, 75 catties of high-quality broodstock with large individuals, bright shell color and mature gonads were selected from freshly caught wild clams, and put into a cultivation pool with a depth of 1.5 meters. During this period, the seawater temperature was controlled at 26-29°C, and the salinity was 26‰-30‰. The pool was moved once a day, and flat algae were fed twice, with a daily feeding amount of 150,000 cells / ml.
[0016] (2) Artificial induction: After 4-7 days of temporary breeding, remove the brood shellfish in poor condition during the temporary breeding process, select 65 catties of high-quality broiler shellfish, dry in the shade in a 23°C cooling box for 1 hour, and use filtered seawater with a temperature of 26°C After being stimulated by running water for 2 hours, they were placed in a seawater pool at 29°C for induced labor, and broodstock were artificially induced to release eggs and sperm.

The invention discloses an artificial breeding method of tapes dorsatus. The tapes dorsatus are one kind of aquatic products for people in inshore areas to eat constantly, and have great economic benefit. In present, the tapes dorsatus in the market are almost natural wild resources, and few of the tapes dorsatus is artificially bred. In the breeding process of the tapes dorsatus, the offspring seed production technology is the bottleneck which limits development of the tapes dorsatus cultivation, and researches and reports about cultivation of the tapes dorsalus offspring seeds do not appear at present. According to the artificial breeding method, the technical measurements of parent scallop cultivation, artificial induced spawning, artificial hatching, D-shaped larva cultivation and juvenile mollusk cultivation are adopted, and a method of artificial factory breeding of the tapes dorsatus is explored. The induced spawning discharge rate reaches 50%, hatching rate is 80%, and total survival rate reaches 8%-12%. And breakthrough is achieved on the method of artificial factory breeding of the tapes dorsatus. No reports of artificial cultivating tapes dorsatus seeds appear before, and the method is strong in practicability, and has a great facilitation function on development of the tapes dorsatus breeding industry.
Description
technical field [0001] The invention relates to a method for artificial seedling cultivation of clams, belonging to the technical field of aquaculture. Background technique [0002] Blunt clam ( Tapes dorsatus ), commonly known as "snail snail", has a large body, thick shell, strong adaptability, muscular feet and soft parts, and beautiful meat. It is one of the aquatic products that people in coastal areas often eat, and has extremely high economic value. At present, there is a large demand for clams in the market, but almost all of the existing clams are natural wild resources, and there are few artificial breeding. Due to the limited natural wild resources, the scarcity of seedlings, and the imbalance between supply and demand, the Clam resources are gradually decreasing. In the process of Clam culture, seed production technology is the bottleneck restricting the development of Clam culture. At present, there are no studies and reports on Clam seed breeding. There are ...
