Aquatic animal temperature selection experimental system

Abstract

The invention discloses an aquatic animal temperature selection experimental system. The aquatic animal temperature selection experimental system is characterized by comprising an outer water tank (1), wherein an inner water tank (2) which is made of heat conduction materials is arranged along the axial direction of the outer water tank (1), the inner water tank (2) and the outer water tank (1) are not communicated with each other, an inlet end of the inner water tank (2) is communicated with a heating water tank (3) through a pipeline, a heater (4) is arranged inside the heating water tank (3), an outlet end of the inner water tank (2) is connected with a recovery water tank (5) through a pipeline, and the outer water tank (1) is connected with a cooling-water machine (6) through a water inlet and outlet pipe. The aquatic animal temperature selection experimental system is simple in structure, exquisite in design, capable of providing continuous water temperature changes, and capable of carrying out research on water temperature application ranges of aquatic animal adults and larvae such as fishes, shrimps, crabs, cephalopodas and the like from the ethology view.

Description

technical field [0001] The invention relates to an experiment system, in particular to an aquatic animal temperature selection experiment system. Background technique [0002] The temperature of aquaculture water is one of the important environmental factors that affect the growth, development, reproduction and other physiological activities of aquatic animals such as fish, shrimp and crab. Mastering the suitable temperature range of animals is not only an important content of biological research, but also a key technical link to ensure the success of breeding production. However, most of the current studies on the suitable temperature for the growth of aquatic animals are grouped by setting different temperature groups to raise them, and carry out post-growth measurements to count the results. This method is not only time-consuming and labor-intensive, but also its results are easily interfered by individual animal differences, feeding management or other factors, sometime...

AI Technical Summary

Problems solved by technology

This method is not only time-consuming and labor-intensive, but also the results are easily disturbed by individual animal differences, feeding management or other factors, sometimes resulting in large deviations in results

However, each breeding group needs to set the temperature artificially. If the temperature gradient is too large, the experimental results will be inaccurate; if the temperature gradient is too small, a large number of breeding devices and experimental animals will be required, which will greatly increase the cost and workload of the experiment.
