A rapid growth technique of barbed bearded seabream

Abstract

The invention discloses a rapid cultivation technology of barbed bearded sea bream; it includes: culture pond treatment: select an oval culture pond, use disinfectant to sterilize the culture pond and culture tools, and then use seawater to clear it for standby; Putting in: adopt the ecological polyculture mode of cross-banded bearded seabream and sea bass; feed feeding: put bait into the breeding pond; absorb the bottom and change water continuously during the breeding period, and use aerated micro-flow water culture to ensure fresh water quality; timely grading: in When pouring and disinfecting the ponds, the slowest-growing individuals are individually selected and raised separately in other water bodies; the competition mechanism of "last place elimination" is adopted; disease prevention and treatment: the fish body is disinfected in dipping baths and ponds are poured during the breeding process. The present invention is a rapid, efficient and healthy cultivation technique for the barbed bearded seabream; the obtained barbed bearded seabream has a higher survival rate, higher body length and weight, higher nutrients and nutritional value, It also contains higher polyunsaturated fatty acids.

Description

A kind of fast growing technology of cross-strap sea bream technical field The invention belongs to the technical field of aquaculture, be specifically related to a kind of fast growing technology of cross-strap sea bream. Background technique Cross-banded sea bream (Hapalogenys mucronatus) is subordinate to Perciforms (Perciforms), Perciidae (Pomadasyidae), Hapalo genys, commonly known as sixteen, are offshore middle- and lower-level fishes that like to live in rocky places In the sea area of ​​​​the reef, it is a typical reef fish, feeding on small fish, crustaceans and shellfish. The cross-banded sea bream has fresh meat The advantages of beauty, high nutritional value, gorgeous body color and high economic value are favored by consumers and fishing enthusiasts. A marine fish with high edible value and ornamental value. At the end of the last century, with the overfishing and With the rapid development of the Hong Kong industry, the amount of wild resources of...

Problems solved by technology

The barbed bream can be put on the market with a weight of more than 3 taels, and the price is high; however, because the breeding technology of the barbed bream is not yet mature and standardized, there are a series of constraints such as slow growth rate and low survival rate of the barbed bream , seriously affecting the breeding benefits and industrial development of the barbed bearded seabream
