Controllable semi-open breeding cabin system

Abstract

The invention discloses a controllable semi-open breeding cabin system. The controllable semi-open breeding cabin system comprises a breeding cabin, a water inlet mechanism, a filtering mechanism and a fish outlet pipe; the water inlet mechanism comprises a water inlet pipe and a plurality of high-pressure water inlet pipes; the water inlet pipe is located on one side of the upper portion of the breeding cabin, and the high-pressure water inlet pipes are distributed in the circumferential direction of the top of the breeding cabin; the tail ends of the high-pressure water inlet pipes are connected with a jet pipe extending into the breeding cabin; a filtering mechanism is arranged at the bottom of the breeding cabin, and the outlet end of the filtering mechanism is located in external seawater; and the fish outlet pipe is arranged on the cabin wall of the breeding cabin, and a gate valve capable of being opened and closed is installed on the fish outlet pipe. According to the controllable semi-open breeding cabin system, on the premise that the marine environment is not damaged, the optimal culture growth environment is provided for rare fishes by utilizing the marine self-purification capacity of the deep sea and the flow field controllable capacity of the culture cabin, and high energy consumption required by operation of a closed circulating water culture system is effectively reduced; Aand the damage to the marine environment caused by pollutants generated by open type culture is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of deep sea fishery, in particular to a controllable semi-open breeding cabin system. Background technique [0002] With the continuous development of society and economy, the pollution of coastal marine environment has increased, the benefits of traditional farming methods have declined, and the diseases of farmed species have become serious. Against the backdrop of increasing rigid constraints on resources and the environment, how to increase the breeding density and unit water output and reduce the pollution of the breeding environment has become an urgent problem to be solved. The current development direction is to expand the breeding space in the open sea, vigorously develop the three-dimensional breeding in marine pastures, and the deep-water cage culture in the open sea as key tasks. Coordinating the development of marine fishery resources, supporting intensive marine aquaculture, optimizing the lay...
