Description

Aquaculture pond based on thermoelectric effect

Technical Field

The invention relates to the technical field of aquaculture, in particular to an aquaculture pond based on thermoelectric effect.

Background

The aquaculture industry is one of the agricultural production departments, which utilizes aquaculture techniques and facilities to perform aquatic economic animal and plant cultivation according to the ecological habits of cultivation objects and different requirements on the environmental conditions of water areas. According to different water area properties, the method is divided into a mariculture industry and a freshwater culture industry. According to the objects of cultivation and planting, the fish, shrimp, crab, shellfish, algae, gordon euryale seed, lotus root, etc. are divided into fish, shrimp, crab, shellfish, etc.

Most aquatic organisms have the defect that the requirement on water temperature and water quality is not strict, but the water temperature sudden change cannot be resisted. Different aquaculture objects have different suitable temperature ranges, and the temperature and the water temperature in different seasons have obvious changes, so that the water temperature needs to be flexibly and actively regulated and controlled to adapt to different aquaculture objects and environmental temperatures.

During aquaculture, the influence of sludge at the bottom of the pond on the aquaculture is large, and the sludge at the bottom of the pond generally needs to be stirred periodically to reduce oxygen consumption in water, particularly at the bottom of the pond. In fine days, the sludge is stirred to the surface layer of water, the oxygen in the upper layer is fully utilized, the decomposition of oxygen debt in the sludge is accelerated, the time oxygen consumption of lower layer water at night is reduced, fish floating is prevented, substance cyclic metabolism and alternating mixing of the upper water layer and the lower water layer are promoted, the decomposition of organic matters at the bottom of the pond is promoted, nutritive salt and trace elements deposited and adsorbed in the bottom sludge are released, and the accumulation of harmful substances in the pond is prevented. Generally, the method is carried out for 1 time in sunny days and windy days every 10-15 days so as to avoid causing pond flooding. After the cultivation in each period is finished, redundant sludge at the bottom of the pond needs to be removed, and quick lime is used for improving the bottom, so that adverse effects of the sludge on the subsequent cultivation are avoided.

The culture pond capable of automatically adjusting water temperature and facilitating sludge cleaning is urgently needed.
