Abstract

The invention provides a fish farming system and a method for water treatment of fish farming. The fish farming system includes a machine shop which is provided with multi-row fishpond groups and every row of the fishpond group is provided with a plurality of fishpond units, and a plurality of microbial treatment systems are connected with the fishpond units. The microbial treatment systems utilize the aquaculture water in the fishpond units to cultivate beneficial microorganism PGRP which has antagonistic effect on the pathogen. And then return the clean water to the fish pond units. A water outlet is arranged at the bottom of each fishpond unit. Every fishpond unit is provided with two inlets, wherein one of the inlets is connected with a high-level reservoir containing a mixture of groundwater and seawater, and the other inlet is connected with the microbial treatment system. The fish farming system and method for water treatment of fish farming has the advantages of water saving and pollution reduction, which is capable of effectively reducing the intakes of seawater and underground hot water, decreasing the amount of aquaculture waste water, achieving the effect of water-saving and pollution-reducing. The fish farming system and method for water treatment of fish farming provides strong support for the implementation of water ecological civilization construction in coastal areas.

Description

technical field [0001] The invention relates to the field of coastal culture, in particular to a fish culture system and a method for treating fish culture water. Background technique [0002] Half-smooth tongue sole (Cynoglossus semilaevis Gunther) is a unique economic fish in the Bohai Bay area. Salt range 14-33‰. [0003] Semi-smooth tongue sole has less natural resources, delicious taste, high meat yield, smooth taste, long-cooked fish meat without aging, no fishy or peculiar smell, high protein and rich nutrition. Semi-smooth tongue sole grows fast, has a low food level, can tolerate low oxygen, and has few diseases. It is suitable for breeding turbot and flounder in greenhouses. It is currently the most promising seawater species for industrialization and earthen pond farming. [0004] The existing factory farming model has a large amount of groundwater extraction [0005] At present, in the coastal industrialized farming process in the Bohai Bay area such as Tianji...
