Embodiment

[0030] Place 2000kg of peeled free-body healthy Fujian oysters in separate cages 20m 3 into the land-based cement pool of 10m 3 Filter the sea water and start aerating. Then put 0.6kg of the mixed nutrient-enhanced mixed powder into the water body, and at the same time access the density of about 5-10×10 4 10m / ml of Chaetoceros muernii and Chlorella 1:1 mixed algal solution 3 . The nutrient-enhanced mixed powder and mixed algal liquid were fed twice a day, and the water was semi-changed twice a day. During the fattening period, the water temperature was controlled at 22 ± 1 °C, and the salinity was controlled at 30 psu, until the oyster meat yield reached more than 20%.

[0031]The land-based fattening method of the invention can simultaneously cultivate a variety of algae to mix and feed them in a certain proportion. Carotenoids are a kind of natural physiological active substances that are beneficial to the human body. Oysters can absorb carotenoids from feed pellets th...

Abstract

The invention discloses a carotenoid-rich oyster land-based fattening method which comprises the following steps: placing oysters needing to be fattened in a land-based cement pond, controlling the temperature of a farm area and the water temperature in the land-based cement pond, blending baits, blending nutrient enrichment mixed powder, feeding the oysters, and stopping feeding the baits and the nutrient enrichment mixed powder one day before harvesting, meanwhile, disinfected and filtered seawater is adopted for running water cultivation. By adopting a roadbed cement pool fattening method, oysters are fed with mixed algae liquid and nutrient enrichment mixed powder, and carotenoid is contained in the nutrient enrichment mixed powder so as to increase the content of carotenoid in oyster tissues and promote the oyster fattening. By means of the method, the yield of the oysters can be increased by 10-20%, the defect that the fatness of the oysters is poor possibly due to a traditional breeding method is overcome, the nutritional ingredients of the oysters can be increased, the flavor and taste of the oysters can be improved, and therefore a new oyster product which is high in fatness and rich in carotenoids is produced.

Description

technical field [0001] The invention relates to a carotenoid-rich land-based fattening method for oysters, in particular to a carotenoid-rich land-based fattening method for oysters that can effectively improve carotenoid content and oyster fertility in oysters, belonging to aquaculture technical field. Background technique [0002] Oyster is the species with the largest annual output among the shellfish farming species in China. It is a popular seafood product on the table of domestic residents, and has a large market at home and abroad. However, at present, domestic oyster farming has the problem of long shells but not meat in some sea areas, especially triploid oysters with relatively higher economic value. Therefore, it is necessary to develop relevant land-based fattening techniques for short-term fattening of oysters to improve oyster production. Soft body, flesh and mouthfeel. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present inve...
