Factory incubation method of Tilapia and production line

Abstract

The invention relates to an incubation and seedling-culturing method of Tilapia and a production device. The incubation and seedling-culturing method of the Tilapia is formed by the connection of a water pump, a main water inlet pipe, an incubatory barrel, a seedling collecting tank, a header tank, a return conduit, a reservoir and the like. The factory incubation method of the Tilapia comprises the following steps of: (1) mating of parent fishes: the mating of parent fishes is implemented in a net cage, the parent fishes are put into the net cage and the mating and the ore laying can be performed when the temperature of water reaches over 20 DEG C. (2) artificial fetching of ores: the ores are fetched out of the oral cavity of the female fish and conveyed to an incubation workshop after being cleaned. (3) incubation on the production line; a main water inlet valve of the production line is opened and the water pump is started up. The fish ores are conveyed into the incubatory barrel, a water inlet valve of the incubatory barrel is dimensionally adjusted so that water stream causes the eggs to turn over at the middle and lower parts of the barrel, the fish seedlings flow into the seedling collecting tank subsequent to the incubation and are then collected for seedling culture. The invention can carry out the mass production of the Tilapia in multiple seasons and 24 hours per day, which meets the demands of the seedling culture in distinct seasons and sufficiently gives play to the effect of technical devices and fishery technologies in the production of seedlings culturing.

Description

technical field [0001] The invention belongs to breeding technology and equipment of aquatic products, in particular to hatching and seedling raising methods and production equipment of tilapia. Background technique [0002] Tilapia is an excellent species recommended by the Food and Agriculture Organization of the United Nations. It has high yield, strong disease resistance, wide appetite, and is easy to breed. Industrialization and export earnings have been formed in my country, especially in the south of my country, where breeding is very extensive. The seed breeding method of tilapia at present mainly is to breed naturally in ponds by female and male broodstock, and fish fry are artificially fished in ponds with dip nets after hatching. This kind of operation is blind, and it is difficult to clean the fish fry in the pond manually; the broodstock still has the habit of eating eggs and fry in the pond; Competing with adult fish for bait, water, and fertilizer seriously ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the present situation that the current tilapia fry production process only relies on natural self-production, low production efficiency, short production season, and low technological content, the present invention provides a tilapia hatching method and production line equipment, which can carry out multi-season, all-weather , large-scale, automatic control hatching factory production
