Constant temperature system suitable for freshwater shellfish fry cultivation

Abstract

The constant temperature system comprises a water temperature control system, a water circulation system and a juvenile mussel breeding system which are arranged in a breeding area, the water temperature control system comprises an electric heating control facility and a water storage pool, and a thermistor is arranged in the electric heating control facility and used for controlling the water temperature; the water circulation system is provided with a reservoir, a lifting pump, a make-up pump and a water level controller, the water level controller can be used for controlling the make-up pump and the lifting pump to be started and stopped, and a water quality purification unit is arranged at the tail end of each juvenile mussel breeding pond in the juvenile mussel breeding system; the constant-temperature culture system for the fresh water shellfish fry can meet the requirement for water temperature in the culture process of various fresh water shellfishes, has a strong seasonal change response mechanism, and can effectively improve the survival rate of juvenile mussels and reduce the construction cost especially in winter and early spring stages. And secondly, the juvenile mussel breeding system has a purification effect on the water body in the circulation process, and the water body in the system can be recycled.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a constant temperature system suitable for artificial cultivation of freshwater shellfish. Background technique [0002] At present, there are many factors affecting the early growth and development of freshwater shellfish, and water temperature, as an important factor, not only has different effects on different species, but also has different effects on different growth and development stages of the same species. Existing research data show that the early developmental stage of freshwater shellfish is an important link in the entire growth and developmental stage, which is obviously affected by temperature. Appropriate water temperature can ensure the normal life activities of freshwater shellfish. When the water temperature changes, the pressure caused by the water temperature change can be reduced by tolerance and resistance within the tolerance range. Once th...
