Parasites as Indicators of English Sole (Parophrys vetulus) Nursery Grounds
Juvenile English sole (Parophrys vetulus) utilize Yaquina Bay, Oregon as a nursery during at least a portion of their first year of life, but the possibility of the existence of additional nursery grounds offshore has not previously been examined. During 1971, young-of-the-year first appeared in Yaquina Bay in February, were abundant from April to September, and most emigrated to offshore areas...
متن کاملMultiplication of Trypanosoma pacifica (Euglenozoa: Kinetoplastea) in English sole, Parophrys vetulus, from Oregon coastal waters.
Multiplication of Trypanosoma pacifica was common in the fish host from observations of live flagellates and Giemsa-stained blood smears. Multiplication began with the elongation of the kinetoplast, thickening of the posterior portion of the body, and appearance of a new flagellum near the kinetoplast. The new flagellum was very rigid when less than 3 microm in length, but it became flexible as...
متن کاملXenoestrogen exposure and effects in English sole (Parophrys vetulus) from Puget Sound, WA.
Vitellogenin, a yolk protein produced in the liver of oviparous animals in response to estrogens, normally occurs only in sexually mature females with developing eggs. However, males can synthesize vitellogenin when exposed to environmental estrogens, making the abnormal production of vitellogenin in male animals a useful biomarker for xenoestrogen exposure. In 1997-2001, as part of the Washing...
متن کاملBiomarkers Signal Contaminant Effects on the Organs of English Sole (Parophrys vetulus) from Puget Sound
Fish living in contaminated environments accumulate toxic chemicals in their tissues. Biomarkers are needed to identify the resulting health effects, particularly focusing on early changes at a subcellular level. We used a suite of complementary biomarkers to signal contaminant-induced changes in the DNA structure and cellular physiology of the livers and gills of English sole (Parophrys vetulu...
متن کاملConsistent associations between hepatic lesions in English sole (Parophrys vetulus) and polycyclic aromatic hydrocarbons in bottom sediment.
A consistent and statistically significant association between prevalence of hepatic neoplasms in free-living sole (Parophrys vetulus) and levels of anthropogenic polycyclic aromatic hydrocarbons in bottom sediment from sites of fish capture was documented in a series of studies conducted over a period of 7 years in Puget Sound, Washington. This result strengthens the evidence supporting a caus...
