Problems solved by technology

[0002] Vietnamese white clam (belonging to the bivalve clam order clam clam family shellfish, is a shellfish seafood, widely distributed in the north and south sea areas of China, it grows rapidly, the breeding cycle is short, and has strong adaptability (wide temperature, wide salt, It is widely distributed), and it survives long time out of water. It is an excellent shellfish suitable for artificial high-density cultivation. In recent years, Vietnamese white clams have become more and more popular among ordinary people, and their artificial cultivation has also been widely promoted. However, Due to unscientific farming techniques, the yield of Vietnamese white clams is low and the cost of farming is high

Abstract

The invention discloses a method for artificial spat culture of Vietnam mactra veneriformis capable of effectively increasing yield. The method comprises the following steps of (1) selecting three-year and above Vietnam mactra veneriformis as parent shells; drying the parent shells in a shady area, stimulating by flowing water, putting the parent shells into ammonia seawater, soaking, enabling the male parent shells to lay sperms, enabling the female parent shells to lay spawns, enabling the sperms and spawns to naturally fertilize in water, forming a larva, using chaetoceros mulleri as feed, and feeding the larva. Compared with the prior art, the method has the advantages that the culture steps are scientific and reasonable; the survival rate of the Vietnam mactra veneriformis larva is effectively improved; the death rate of the Vietnam mactra veneriformis larva is decreased by 11%, and the yield is increased by 18%.
