An ecological engineering setting method for nearshore fish culture rock reef ponds

Abstract

The invention discloses an ecological engineering arranging method for an offshore fish type aquaculture ledge pond, and belongs to the technical field of aquaculture. The ecological engineering arranging method comprises construction of the pond wall and the surrounding wall of the pond, water system setting, arranging of a pollutant discharge reduction control system, arranging of an oxygenation and circulation system and arranging of a water quality and behavior monitoring system. According to the ecological engineering setting method, by the engineering setting of the pond wall and the surrounding wall of the offshore fish type aquaculture ledge pond, a substrate, water feeding and drainage systems, the pollutant discharge control system, the water quality and behavior monitoring system and the like, the resistance performance of the ledge pond for natural disasters is greatly improved, the pollution pressure on an environment in an offshore area due to aquaculture wastes in the ledge pond is reduced, factory management and high and stable yield of the offshore fish type aquaculture ledge pond are realized, and the aims of improvement of the quality and the effectiveness, transformation and upgrading of seawater pond aquaculture are fulfilled.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an ecological engineering setting method for rocky ponds for cultivating nearshore fish. Background technique [0002] The aquaculture area of ​​seawater ponds in my country reaches 457,000 hectares, and the aquaculture production accounts for 12.67% of the total aquaculture production ("China Fishery Statistical Yearbook", 2014). At present, seawater ponds in my country can be divided into large-scale extensive aquaculture ponds, small-scale intensive ponds, engineering ponds, and near-shore rock ponds according to their specifications, layout, and structural characteristics. Nearshore rock reef ponds are mostly distributed in intertidal coastal areas or estuary areas along the northern coasts of Shandong, Liaoning, Hebei, etc. Most of them were simply surrounded by early seaside fish ponds, mainly for fish farming. Fish culture in reef ponds has the advantages ...
