Description
Technical field
The present invention relates to aquatic animal and expose experimental provision and application, especially relate to a kind of aquatic animal toxicological experiment system and application.
Background technology
1. the method that current use zebra fish carries out organic matter toxicological test has is that capacitance divider hydrostatic is raised, and arranges parallel group (same concentrations group) and control group, the residual bait of timing sucking-off, ight soil, and changes testing liquid.2. adopt and divide the flowing water combination unit of parallel group to raise, every parallel group of independent filtration residual bait, ight soil, and change testing liquid.But said method 1. in test process soil pick-up time-consuming: during test, Partial Species organic matter volatilizees or is adsorbed in ight soil, residual bait, chamber wall etc. in test process from solution, the difference etc. of parallel group of each container difference soil pick-up, respectively replacing solution amount, all can cause solution concentration in each parallel group of container that larger variation occurs, test solution concentration in parallel group of each container is caused to form difference, serious reduction repeated test effect.Said method 2. in process of the test pollutant easily from solution volatilization or be adsorbed in ight soil, residual bait, chamber wall etc., parallel group of each container absorb residual bait ight soil respectively, parallel group of each container can not carry out solution equilibrium very well, solution concentration in parallel group of each container is caused to fluctuate equally, reduce repeated test effect, sucking-off residual bait ight soil workload is large.If volatile contaminant toxicity test, in experimentation method 1. with method 2. pollutant volatilization easily cause indoor pollution, threaten experimenter healthy.
Chinese patent CN201821759U discloses the aquatic organism cultivating system of a kind of drip water-feeding type for toxicological experiment, comprise support, supporting layer, cultivation flume, return flume, purification tank for liquid waste, the filtering cloth jar with multilayer supporting layer, and water-supply-pipe and control valve; Be provided with water storage box at cradle top, formed the dribble-feed inlet pipeline of cultivation flume by hydraulic pipeline and control valve; Unidirectional cultivation water system is formed again by drainpipe and purification tank for liquid waste outside cultivation flume and breeding trough; Described supporting layer is provided with the water bath of water temperature in controllable breeding trough, and described cultivation flume is placed in water bath; In addition, water bath water inlet, the water bath overflow plate of described water bath by water bath is arranged, and the water bath backflash mated with water bath, water bath return duct, filtering cloth jar form temperature control circulator bath system; Described cultivation flume top is furnished with charge valve.Water system in this patent is that the solution concentration of toxicological experiment is then consistent, and cannot realize parallel exposure in groups by being connected on connection water-supply-pipe on each cultivation flume and control valve forms top-down water system.And this system does not have dirt-collecting unit, the clean stable of exposed environments cannot be ensured, be unfavorable for breeding of aqueous bio.
