Embodiment

[0020] On July 12, 2013, samples of variegated clams were collected in Naozhou Island, Zhanjiang, in order to ensure the species unity. Place it in the cement pool of the Hengxing South Ocean Biotechnology Co., Ltd. nursery ground, and let it stand for a while. When the water pipe stretches out, grab all the individuals whose water pipes are free from the base, and remove the water pipes that do not extend out and the water pipes from the bottom. The Philippine clams that started to dissociate from the top, and the remaining ones are the variegated clam samples. .

[0021] 2000 pure variegated clam individuals with a shell length of 3.0-3.6 cm were screened out as parents. Place it in an indoor cement pool, and use micro-inflation and artificial feeding of unicellular algae to promote ripening. Since this season is in the breeding season of the variegated clam, the gonads of the variegated clam itself are very good, but they have not yet matured. After 8 days of feeding, the...

Abstract

The invention discloses an artificial breeding method of Ruditapes variegata, and a large of healthy offspring seeds are cultured indoors by the links of parent sample collection, gonad maturation acceleration, parturition hastening and incubation, larva cultivation, substratum-free offspring seed collection, juvenile mollusk breeding and the like. The awkward situation that R. philippinarum is mistaken for the Ruditapes variegata by most people in the prior art, and the real artificial breeding of the Ruditapes variegata does not exist is over, the healthy offspring seeds of the Ruditapes variegata are cultured for the first time, and a solid foundation is established for recovering the biological resources of the Ruditapes variegata and maintaining the genetic polymorphism of the Ruditapes variegata. The artificial breeding method has the advantages of simpleness in operation, strong practicability, easiness in popularization and the like.

Description

technical field [0001] The invention relates to the technical field of shellfish seed breeding in modern marine agriculture, in particular to a variegated clam Ruditapes variegata artificial breeding method. Background technique [0002] variegated clam Ruditapes variegata , is a clam ( Ruditapes Chiamenti , 1990), Claminae ( Tapetinae H. & A. Adams ) Clamidae ( Veneridae Refihesque , 1815), a tidal flat shellfish, and the Philippine clam Ruditapesphilippinarum are two species of the same genus (Zhuang Qiqian, 2000). [0003] variegated clam Ruditapes variegata Distributed in the south of Pingtan, Fujian, my country, Guangdong, Guangxi, Hainan and other places, it likes high temperature environment, and the wild catch is very limited. Along with industrial pollution and tidal flat shrinkage, the resources of this species are very scarce; while the Philippine clam Ruditapesphilippinarum It is distributed in the north and south coasts of my country, with a wide ran...
