Radiation causes dominant lethal mutations in the medaka (Oryzias latipes) (Shima and Shimada 1991). Mosquitofish (Gambusia spp.) from radionuclide-contaminated ponds in South Carolina differed from conspecifics in reference ponds, as judged by the frequency of DNA markers, and this is consistent with the hypothesis that these DNA markers may originate from genetic elements that provide a selective advantage in contaminated habitats (Theodorakis et al. 1998). Ionizing radiation at low-level chronic exposure reportedly has no deleterious genetic effects on aquatic populations because exposure is compensated by density-dependent responses in fecundity (IAEA 1976). However, this needs verification.

Phycotoxins accumulate in fish and shellfish because of the natural feeding habits of the respective organisms, rather than because of food handling or processing practices. The toxins causing the diseases discussed in this chapter are heat stable (Australia New Zealand Food Authority, 2001 Committee on Evaluation of the Safety of Fishery Products, 1991). Complete inactivation of saxitoxin (associated with PSP) requires at least ten minutes of exposure to 260°C dry heat. Brevetoxins (associated with NSP) were inactivated (i.e., to levels below the limit of assay detection using Japanese medaka [Oryzias latipes]) by exposure to 500°C heat for 10 to 15 minutes (Poli, 1988). Complete inactivation required 10 minutes exposure to 2760°C dry heat (Wannamacher, 2000).
