Acute effects of kaolinite suspension on eggs and larvae of some marine teleosts.

To evaluate the effects of suspended inert particles on the early life stages of the eggs and larvae of four marine fish species, Pagrus major, Acanthopagrus schlegeli, Oplegnathus fasciatus and Parapristipoma trilineatum were exposed to kaolinite suspensions up to 10,000 mg l-1. Hatching success and developmental rates of eggs all species were not significantly affected by 10,000 mg l-1 suspension over a 24-h exposure period. Exposure of larvae of each species to suspensions ranging from 32 to 10,000 mg l-1 for 1, 3 and 12 h, however, resulted in over 50% mortality at 1000 mg l-1 for 12 h.
