Abstract

The invention relates to an industrial culture device capable of simulating a flounder paralichthys wild benthic environment. The industrial culture device comprises a culture pond, wherein a general blow-off hole is formed in the middle of the bottom of the culture pond; a hollow water level column for adjusting a water level is mounted on the general blow-off hole; a horizontal porous carrying platform for segmenting the bottom of the culture pond to form a lower blow-off layer space is arranged above the bottom of the culture pond; a sand filtering thin film covers on the upper surface of the porous carrying platform; a natural sea sand layer is arranged on the sand filtering thin film; an upper air guide pipe, which is connected with an air pump, is mounted on a peripheral side wall of the culture pond on the upper surface of the natural sea sand layer; and airflow blown out from an air guide hole of the upper air guide pipe passes through the upper surface of the natural sea sand layer, so that the natural sea sand layer is stirred. By adopting the industrial culture device provided by the invention, separation of blow-off and a habitat environment is realized and the quality of the habitat environment on an upper layer of a pond bottom is guaranteed, so that the condition of blind side melanism of flounder paralichthys is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of aquaculture equipment, in particular to a factory culture device for simulating the wild benthic environment of flatfish. Background technique [0002] Flounder is an important economic species of aquaculture in my country. With the development of factory farming, efficient and intensive production methods are increasingly recognized by farmers. The intensive factory-like production abandons the natural growth environment of farmed species, and captures the core elements to complete the optimal design of space and equipment. However, there are also certain practical problems: such as high-density farming brings resistance to stress compared with wild populations. The degradation of sex, the difference in the appearance of farmed fish and wild fish caused by the factory environment, etc. In order to simulate the wild benthic environment, it is necessary to practice a factory farming device that can simul...
