Danio rerio Experimental Exposure, Stress and Fecundity - AB experiment. The number of pairs of zebrafish spawned, eggs laid and hatched and the percent viable larvae surviving to 5 days post-fertilization (dpf) at wks 8, 13, and 20 post-exposure (PE) to Stress, Pseudoloma, Pseudoloma and stress and control conditions (no stress and no Pseudoloma). Tank A and B indicate replicate tanks within the same treatment.
