Experiment method and system for researches on seawater environmental stresses

Abstract

The invention discloses an experiment method and system for researches on seawater environmental stresses. According to the experiment method, a mother solution of the seawater environmental stresses is added to a culture water tank with a drop method and is uniformly mixed with surrounding seawater through a mixing device, and the shellfish culture environment is changed gradually. The system comprises an environmental stress device for accommodating the mother solution of the environmental stresses and a culture device located below the environmental stress device, wherein the environmental stress device comprises an airtight water storage tank provided with a water inlet sealing screw cap above, the lower side of the airtight water storage tank is connected with a gas inlet pipe and a liquid outlet hose respectively, and a speed-changing knob is further arranged on the water outlet hose; the culture device is a culture water tank accommodating seawater, and an oxygen inflating device is further arranged at the bottom of the culture water tank; the mother solution is mixed to the culture water tank through the liquid outlet hose in a suspended dripping manner. With the adoption of the experiment method and the experiment device, the living environment of bivalve mollusks can be truly gradually changed, other interference factors are avoided, and the accuracy and the precision of the experimental researches on the seawater environmental stresses are improved.

Description

technical field [0001] The invention relates to seawater environmental stress research, in particular to an experimental method and system for seawater environmental stress research. Background technique [0002] With the promotion of the intensive farming model, the aquaculture industry has developed rapidly. However, due to high-density breeding, increased frequency of feeding, abuse of disinfectants and drugs, and inappropriate management methods, etc., the pollution of the breeding water is increasing, and the breeding environment is deteriorating, causing the animals to be under the stress of various environmental factors. Under the circumstances, it leads to the breeding of animal diseases and the decline of breeding benefits, which seriously hinders the healthy development of the aquaculture industry. In order to ensure the sustainable development of the aquaculture industry, it is necessary to maintain an excellent breeding environment as much as possible so that th...
