An engineered pond recirculating aquaculture system for flounder and flounder

Abstract

A flounder and flatfish engineering pond recirculating aquaculture system belongs to the technical field of marine aquaculture. The system comprises a water storage pond, a back water treatment pond, a coarse filtration pond, a conjoined combination aquaculture pond, a water feeding and drainage system, an oxygen supply device and a water quality monitoring system. On the one hand, the system still uses a traditional earthen pond aquaculture mode for culturing flounder and flatfish to grow in an environment similar to the wild so as to improve the quality of farmed flounder and flatfish. Meanwhile, engineering and systematic arrangement and layout are performed on the outdoor culture earthen pond to achieve factory and information management of flounder and flatfish pond culture, the output of farmed flounder and flatfish such as bastard halibut can reach to 1000-2000kg / mu (one mu equals about 1.667square meters), increasing 5-10 times of the output of traditional large single pond culture, and the culture efficiency and economic and ecological benefits are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of marine aquaculture, and in particular relates to an engineered pond circulating aquaculture system for flounder and flounder. Background technique [0002] my country has a vast area of ​​mariculture ponds, with a breeding area of ​​413,000 hectares, and the aquaculture production accounts for 13.35% of the total mariculture production ("China Fishery Statistical Yearbook", 2011). At present, most of the marine fish culture ponds in my country are set up and constructed according to the shrimp culture ponds. Most of the ponds are large and have simple overall structures, lack of facilities and equipment, and can only be used for extensive farming. Because large ponds are not easy to manage, residual bait, feces, etc. Too much deposition due to failure to discharge in time can easily lead to problems such as water quality deterioration and disease occurrence, and the breeding efficiency and benefits are low...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an engineered pond recirculating aquaculture system for flounder and flounder, to meet the requirements of the country for low-carbon eco-friendly aquaculture, and to solve the problem of unreasonable structure of flounder and flounder breeding ponds in my country For the problems of unreasonable resource utilization and low breeding efficiency, the present invention includes a conjoined combined culture pond composed of 6-8 small single ponds connected in series and in parallel, which can realize the informatization and industrialization of pond culture of flounder and flounder At the same time, it can realize the recycling of pond aquaculture water, ensure the daily water exchange rate of aquaculture ponds reaches more than 50%, and greatly improve the efficiency of aquaculture
