Embodiment Construction

[0032] The equilateral clam artificial nursery method provided by the invention, its process is:

[0033] 1. Baby's temporary care

[0034] Use sand filter seawater to rinse off the dirt on the surface of the shellfish; then put it in 10mg / L potassium permanganate solution for disinfection for 2 minutes, and then rinse it with clean water. Then evenly sow the parent shellfish in a holding pond with a sandy bottom with a thickness of 10cm, and the holding density is greater than 2kg / m 2 , less than 3kg / m 2 . The water depth of the holding pool is 50cm. The water temperature of the seawater in the pool is controlled at 15-25°C, the salinity is above 15 and below 20, the pH value is 7.8-8.5, and it is continuously inflated. Change the water once a day, 20% of the daily water change. Feed the bait of Monocystis 2~3 times a day, the bait is mainly Chrysophytes, supplemented by Chlorella, Chlorella, and Flatweed. =6︰2︰1︰1, the bait density in the pool water is maintained at 40,...

Abstract

The invention provides an artificial breeding method of Gomphina aequilatera. Some parameters in the whole process including temporary culture of parental mollusk, induced spawning, incubation, larvae cultivation, juvenile mollusk culture and the like are adjusted; especially, the salinity of the adopted seawater and the granularity of sand grains for a larvae adherance are reduced; in other words, the salinity of the seawater is controlled to be above 15 in the whole process, and during the juvenile mollusk culture, the granularity of the sand grains for the sand matrix as the adherance is lower than 80; the sand matrix is 2mm+ / -0.2mm thick; the thickness of the matrix is increased by 0.2mm every five days as the juvenile mollusk grows. Compared with the prior art, the artificial breeding method has the advantages that the survival rate of the relatively incubated larvae of the qualified juvenile mollusk is increased and can be above 30%, and in particular, the survival rate of the juvenile mollusk is even increased to 50%.

Description

technical field [0001] The invention relates to a method for artificial seedling cultivation of equilateral clams. Background technique [0002] The equilateral clam Gomphina venerformis (Lamarck) belongs to the genus Lamarck and is endemic to the coast of the western Pacific Ocean. The equilateral clam has delicious meat and has been the main object of coastal residents to catch the sea since ancient times. It is a high economic value. Edible bivalves. The method of artificial seedling cultivation of equilateral clam disclosed in "Journal of Zhejiang Ocean University (Natural Science Edition)" Volume 27 in 2008 "Preliminary Report on Artificial Clam Clam Breeding Experiment" is: [0003] 1. Baby's temporary care [0004] Use sand to filter seawater to wash away the dirt on the surface of broccoli, spread it evenly on the bottom of the cement pool, add sand and filter water to 60-70cm, and then raise it temporarily for 2 days, then remove impurities and damaged and dead in...
