Breeding method for siniperca chuatsi

Abstract

The invention discloses a breeding method for siniperca chuatsi. The method comprises the following steps that 1, a breeding pond is divided into a breeding area and a water quality control area by afirst purse seine, a first aeration device is installed in the water quality control area, the breeding area is divided into a concentration area and a growth area by a second purse seine, a second aeration device is installed in the growth area, and the total area of the breeding pond is A mu; 2, filter-feeding fishes and benthic fishes are put into the water quality control area and fed with filter-feeding fish feed and benthic fish feed; 3, 8-12 days later, siniperca chuatsi each of which is 6-12 g in specification is put into the concentration area, the putting quantity is 2,000-4,000 A, and the siniperca chuatsi is fed with siniperca chuatsi feed; 4, after the siniperca chuatsi is bred in the concentration area for 5-15 days, the second purse seine is removed. The breeding method forthe siniperca chuatsi can ensure that the water quality of a breeding farm is good and stable, and achieves a good breeding effect.

Description

technical field [0001] The invention relates to the field of fishery science and technology, in particular to a method for cultivating mandarin fish. Background technique [0002] Mandarin fish is one of the important freshwater aquaculture economic fish in southern my country. The feed protein consumed by mandarin fish is high, which will easily lead to the increase of water quality indicators such as ammonia nitrogen and nitrous acid in the water body, and make mandarin fish infected with parasites and bacterial diseases. Affect the growth of mandarin fish, cause hidden dangers in the safe breeding of mandarin fish, and greatly limit the development of mandarin fish breeding scale and industrialization. How to maintain the algae phase in the water body, control the transparency of the water body, and maintain the water quality of the farm are the key issues that need to be solved urgently for mandarin fish farming. Contents of the invention [0003] The purpose of the pr...
