GB/T 21806 Chemical Fish Juvenile Growth Test
3 Terms and Definitions
Terms and definitions defined in GB/T 21806 apply to this document.
4 Information required for the test substance
The information required for the test substance includes.

j) Rapid biodegradation test results.
5 Principles of the method
The rare larvae of the exponential growth stage were weighed as the test fish and put into the test container, and were placed in the test container at the sub-lethal concentration of the test substance.
Exposure to flow-through test conditions or semi-static test conditions over a range of degrees. The test period is 28d. Feed every day, the amount of bait is based on the test fish
The initial mass is calculated, and the feeding amount is allowed to be recalculated after 14 days. At the end of the experiment, the experimental fish were weighed again, and the index was estimated by the regression model.
Concentrations ECx, such as EC10, EC20 or EC30, which change from x percent (x%) growth rate, were analyzed for their effect on growth rate. In addition, you can also
The lowest observable effect concentration (LOEC) and no observable effect concentration (NOEC) were determined by comparison with the control group.
