Ichthyotoxicity

Outcomes of antibacterial and antipredatory screening tests. Results for the ichthyotoxicity tests indicate the number of fish (out of three) killed within the 1.5 h exposure period, and the time of first mortality.

Ichthyotoxicity among respective pavoninins did not differ much, all being lethal to Japanese killifish at 5-10 ppm.

Blooms of the marine microalga Fibrocapsa japonica (Raphidophyceae) are suggested to lead to the diminution of fish stocks, but the exact mechanism(s) involved in ichthyotoxicity is still unclear.
