Efficient ecological culture method of black carps

Abstract

The invention discloses an efficient ecological culture method of black carps. The efficient ecological culture method is characterized by comprising the following steps: 1, pond treatment: reconstructing a pond to build a modern ecological pond; 2, fingerling stocking: selecting a suitable stocking density to stock black carp fingerlings, and stocking silver carp fingerlings and bighead carp fingerlings together with the black carp fingerlings; 3, feed feeding: feeding feeds by adopting a fixed point feeding mode, feeding floating pellet feeds, and controlling the feeding amount, the feeding time and the feeding temperature; and 4, culture management: paying attention to oxygenating, improving the water quality, maintaining the water depth and preventing diseases. The culture method optimizes the culture mode, improves the culture environment, and effectively improves the yield and the quality of the black carps and bighead carps raised together, thereby improving the culture benefits and the ecological benefits.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an efficient ecological breeding method for herring. Background technique [0002] In my country, the aquaculture output of the four major carp herring, grass carp, silver carp and bighead carp accounts for about 80% of the total output of freshwater aquaculture species, and they are important food materials for people's daily life. As one of the four major fishes, herring is commonly known as green grass carp, green head, black green carp, etc. It is a carnivorous fish and is an important fishery resource in the middle and lower reaches of the Yangtze River and lakes along the river. The main breeding areas are in Hubei, Jiangsu, Zhejiang and other places. Mainly pond culture. Herring has large individuality, tender meat, large but few thorns, and high nutritional value. It is favored by consumers, so the breeding area is also expanding. According to statistics, in 2013, t...

Problems solved by technology

[0003] Traditional herring ponds are mostly earthen ponds. With the accumulation of time, the ridges of the ponds are prone to aging and collapse, and the bottom of the ponds is too deep. The pond breeding capacity is getting smaller and smaller, and the breeding environment is getting worse.

At the same time, due to the fact that traditional herring farming often feeds sinking pellets, coupled with the backward farming model and management technology, the phenomenon of "emergency medical treatment" is serious, resulting in frequent breeding diseases and outbreaks of diseases, which in turn cause breeding benefits and ecological problems. The phenomenon of low efficiency
