Method for cultivating scatophagus argus in indoor cement pool

Abstract

The invention provides a method for cultivating scatophagus argus in an indoor cement pool, and relates to scatophagus argus cultivation. The method comprises the steps of yearling cultivation, overwintering cultivation and adult fish cultivation, and is characterized in that juvenile fish is firstly placed in a cement pool net cage in a vinyl house for temporary rearing after transported to the destination, the adapted juvenile fish is placed in a cement pool for domestication cultivation, cultivation water adopts natural seawater in river mouth district, the salinity is 8-15, the cultivation water is filtered by 200-mesh bolting silk after secondary precipitation, the cultivation is performed until November to December, the water temperature is lower than 12 DEG C, scatophagus argus is transferred to the indoor cement pool for overwintering cultivation, seawater buoyancy No. 2 grains are fed by two times every day according to 1%-3% of fish weight during the overwintering cultivation, and the water temperature during the overwintering cultivation is kept higher than 12 DEG C; and the water temperature in the spring of next year is increased to be higher than 15 DEG C, yearlings are transferred to the cement pool in the vinyl house from the indoor cement pool for adult fish cultivation, the body length of adult fish is up to 8-10 cm, pool separation is performed, and fresh enteromorpha or filamentous algae are fed during daily management period.

Description

technical field [0001] The invention relates to money fish culture, in particular to a money fish indoor culture method. Background technique [0002] money fish ( Scatophagus argus Linnaeus ), also known as the golden drum fish, belongs to the genus of the genus Chrysalis in the suborder Perciformes. The money fish has a beautiful body, colorful colors and delicious meat. It is a rare seawater economic fish with ornamental and edible value. The money fish has strong environmental adaptability, disease resistance and stress resistance. It can not only grow and develop in seawater and brackish water, but also suitable for breeding in fresh water. It has become one of the important developed species in recent years. At present, many areas in Southeast Asia and my country's Guangdong and Guangxi are exploring the outdoor pond artificial culture and cage culture of money fish. These breeding methods are highly dependent on ambient water temperature and dissolved oxygen, which ...

Problems solved by technology

At present, many areas in Southeast Asia and my country's Guangdong and Guangxi are exploring the outdoor pond artificial culture and cage culture of money fish. These breeding methods are highly dependent on ambient water temperature and dissolved oxygen, which limits the increase in stocking density and is inconvenient for management and observation.

It is necessary to study the method of using indoor cement ponds for breeding to solve the above problems; it is necessary to regulate water quality factors such as water temperature and bait feeding to ensure its nutrient absorption, promote the growth and gonad development of money fish, and obtain high-quality parents; The problem of the low survival rate of fish transportation solves the problem that the parental stress response is strong to the point where the female fish stagnates and the male fish releases the semen by itself during artificial breeding
