Pac Sci 29(4): 349-352.0030-8870http://hdl.handle.net/10125/1513Toxicity studies of various bivalves at Port Moresby were carried out by mouse bioassay. Crassostrea echinata was found to lose paralytic shellfish poison after 3 weeks in a closed seawater system, although toxin is retained for a much longer period in vivo. Four bivalve species tested were as toxic at 10 meters depth as they were at 2 meters. Toxin was not distributed evenly through the tissues of bivalves investigated.en-USArticle
