Abstract

The invention relates to a fishpond. The fishpond comprises a fishpond body, a sealing cover seat is arranged on the inner wall of the fishpond body and is provided with a sealing cover, the sealing cover is of arch structure, and an evacuation valve is arranged at the top of the sealing cover; an oxygenation pipe is arranged in the fishpond body. Oxygen is fed by the oxygenation pipe and undissolved oxygen rises to the upper portion of the arch sealing cover. The sealing cover and the sealing cover seat are submerged in the water to form liquid seal, and closed pure oxygen space between the sealing cover and the water surface is formed. The problems that farming density in industrial fish farming is hard to improve, oxygenation equipment is complicated, energy consumption is high, pure oxygen utilization rate is low and farming operation is inconvenient are solved, and economic benefits of the aquaculture industry are increased.

Description

technical field

[0001] The invention relates to a fish pond, in particular to a fish pond and a high-density fish cultivation method, and belongs to the technical field of fish cultivation. Background technique

[0002] The dissolved oxygen content of the water body is the main limiting factor of the density of fish farming. In high-density fish farming, the continuous flow and exchange of the fish farming water body provides dissolved oxygen for the fish and takes away metabolic waste. The water exchange rate in the fish pond is limited by the fish's adaptation to the flow rate, and the fish culture density in ordinary flowing water is only 10-20kg / m 3 , Artificial oxygenation can increase the dissolved oxygen content in the water body and increase the density of fish farming. Mechanical aeration is commonly used in industrial fish farming. Under the condition of using air as the oxygen source, the density of fish farming can reach 30-50kg / m 3 ;Using pure oxygen as the ox...
