Aquatic animal toxicology experiment system and application

Abstract

The invention relates to an aquatic animal toxicology experiment system and application. The experiment system comprises at least one experiment group formed by a culture unit and a filtering and inflation unit, wherein the culture unit comprises a plurality of culture troughs and a sewage discharging and separating channel, and the lower portion of each culture trough is communicated with the sewage discharging and separating channel; the filtering and inflation unit comprises a water pumping mechanism, an inflation mechanism and a circulation water tank which is communicated with the sewage discharging and separating channel; filtering media are arranged in the circulation water tank, and sewage discharged by the culture unit enters the culture unit circularly through a culture unit water inlet pipe connected with the water pumping mechanism after being filtered by the filtering media and inflated by an inflation mechanism. The system can be applied to the experiment of toxicology of organic pollutants to aquatic animals, the experiment of influences of physical and chemical factor differences on physiology of the aquatic animals, breeding and culture of the aquatic animals and the like; compared with the prior art, the system can achieve liquid balance and automatic pollutant removal in multi-parallel treatment in high quality and reduce labor cost and human disturbance at the same time.

Description

technical field [0001] The invention relates to an aquatic animal exposure experiment device and its application, in particular to an aquatic animal toxicology experiment system and its application. Background technique [0002] At present, the methods of using zebrafish to carry out organic toxicology tests are as follows: (1) Rearing in separate containers in static water, setting up parallel groups (groups with the same concentration) and control groups, sucking out residual bait and feces regularly, and replacing the test solution. ②The animals were reared in a running water combination device divided into parallel groups, and each parallel group independently filtered residual bait and feces, and replaced the test solution. However, the above method ① is time-consuming to absorb dirt during the test process: during the test, some types of organic matter volatilize from the solution or adsorb on feces, residual bait, container walls, etc. The difference in the amount of...
