The major constituents of the shelf cluster were English Sole
(Parophrys vetulus) and Petrale Sole.
Fish in other polluted waterways, including brown bullhead catfish and English sole
, also exhibit high levels of cancer.
In winter, following the development of the `dead zone' area, sandabs and English sole
go there to reproduce.
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
Sediment-dwelling English sole
living in and around Seattle's urban waterfront exhibit spawning anomalies that might compromise their reproductive success, a team of aquatic biologists finds.
It included the dinner menu for the event: olives, salted almonds, English sole
, mallard duck, beef a la Portuguese, Roquefort cheese.
In parts of Burrard Inlet, 80 percent of the English sole
have precancerous tumors and lesions, probably from fossil fuel hydrocarbons in the runoff.
Size-at-age data are not available for most species, but for English Sole
(Parophrys vetulus), the most common species, available aging data (senior author, unpubl.
The researchers compared DNA extracted from the gills of English sole
in the Duwamish River (which flows into the sound through a heavily industrialized area in south Seattle) to DNA taken from fish in the relatively clean Quartermaster Harbor.
Fecal samples collected in SFB indicate that harbor seals in this region feed on Pacific herring (Clupea pallasii), northern anchovy (Engraulis mordax), plainfin midshipman (Porichthys notatus), Pacific staghorn sculpin (Leptocottus armatus), white croaker (Genyonemus lineatus), yellowfin goby (Acanthogobius flavimanus), jacksmelt (Atherinopsis californiensis), and English sole
(Pleuronectes vetulus) (Torok, 1994).
Structural differences were identified in gill DNA from two groups of English sole
collected from Puget Sound, Washington, in October 2000.
(Parophrys vetulus), and blacksmelts (Bathylagidae).
