| influence of a thermal discharge on parasites of a cold-water flatfish, pleuronectes americanus, as a bioindicator of subtle environmental change. | a study was conducted to ascertain the influence of a thermal discharge on the health and parasites of a coastal cold-water flatfish, the winter flounder (pleuronectes americanus), a species sensitive to environmental change. flounder were sampled in spring 1998 and 1999 beneath the plume and at reference sites north and south up to 1 km from the discharge. species diversity and estimates of abundance of macroscopic algae, invertebrates, and fish were also recorded. after capture by scuba divers ... | 2007 | 18163365 |
