The invention provides a Thais bronni breeding method. The Thais bronni breeding method comprises the following steps of: collecting and incubating fertilized eggs; cultivating larvae; and cultivating juvenile mollusks, wherein the fed baits in the pelagic period of larva cultivation comprise chrysophyceae, chlorella, tetraselmis and chaetoceros in a ratio of 10:1:1:1; during metamorphosis period before juvenile mollusk period, the varieties and the amounts of the fed baits, including shrimp slices and razor clam meat, are increased along with time; and the prawn slices and the razor clam meat with a certain ratio are maintained during cultivation of the juvenile mollusks. According to the thais bronni breeding method, different bait constitutions and feeding amounts are provided for successful growth of the thais bronni in each development stage of the thais bronni. Compared with the prior art without artificial breeding, the method establishes the basis of artificial breeding of the thais bronni, so that artificial culture of the thais bronni can meet the requirements of the market.

The invention discloses a nutrition reinforcement method of improving artemia growth and increasing an EPA (eicosapentaenoic acid) content. Continuous feeding of tetraselmis can effectively improve the artemia growth and increase the EPA content when an artemia grows to 3 years. The method can increase a utilization rate of algae food, improves growth quality of the artemia and provides high-quality bait for aquaculture.

The invention discloses a cyclinasinensis purification reproduction and culture method. The method includes the processes of temporary culture of parent clams, spawning of the parent clams, trochophore hatching, D-larvae and post-larvae culture and juvenile clam culture. Microbial preparations are thrown in during the process of temporary culture of the parent clams, a chitosan decontamination agent is thrown in during the process of spawning of the parent clams, the microbial preparations are thrown in during the course of trochophore hatching, microalgae preparations are thrown in during the course of D-larvae and post-larvae culture, and juvenile clams are fed with tetraselmis in the period of juvenile clam culture till grown-up cyclinasinensis is harvested. Purification substances are thrown in the whole period from temporary culture of the parent clams to larvae culture and juvenile clam culture for purifying meat, pollution of contaminants is avoided from the source, healthiness, greenness and non-pollution in the culture process are guaranteed, the contaminants such as heavy metal, petroleum and nitrofuran derivatives in bodies of the grown-up cyclinasinensis are reduced significantly, and good effect on removal of escherichia coli, sphingomonaspaucimobilis, vibrio, aeromonassalmonicida and the like is achieved, and the grown-up cyclinasinensis completely conforming to food security can be cultured.
