A study of possible chemical mediators of a hypersensitivity reaction in teleost fishes.
… As a model of cutaneous anaphylaxis, chopped plaice skin was incubated with a fish Ringer saline in the presence of a fungal challenging agent, Epidermophyton floccosum. A mammalian smooth muscle contracting material was found to be released, reaching a maximum after sixty minutes incubation. …

Arsenic Speciation in Food
… in cod, dab, haddock, lemon sole, mackerel, plaice and whiting. Levels ranged between 1.0 mg kg-1 dry weight in the mackerel, to 187 mg kg-1 in the plaice. Mackerel also contained DMAA and possibly a lipid bound arsenic species. No degradation of arsenobetaine to more toxic species was …

Pathology of parasitic infections in marine teleosts
… response was induced by R. -johnstonel in plaice, and was composed mainly of cells of the macrophage series, which included epithelioid and giant cells. Fibroblasts and collagen deposition formed the periphery of the lesion which was Interpreted as a granuloma. Eggs released by this …

Ecological impacts of shrimp trawling on juveniles of selected benthic fish species in the southwestern Gulf of Maine
… Myoxocephalus octodecemspinosus , while American plaice, Hippoglossoides platessoides, was the dominant species in Site 2. Red hake, Urophycis chuss was abundant at both sites. There were also seasonal differences in the flux of fish at the two sites.</p><p>Correlation analysis showed the …

The determination and environmental significance of planar aromatic compounds in the marine environment.
… and PAHs in sediments and of CBs in mussels and plaice were determined in the Firth of Clyde. Pattern analysis and normalisation to particle size and total organic carbon identified 5 regions of sediments with different levels and patterns of planar aromatic compounds. The patterns and levels at …

Food Resource Utilization By Five Species Of Benthic Feeding Fish In Passamaquoddy Bay, New Brunswick
… winter flounder (Pseudopleuronectes americanus), plaice (Hippoglossoides platessoides), cod (Gadus morhua) and witch flounder (Glyptocephalus cynoglossus). After reducing the size of the data matrix by removing redundant variables (prey items), interspecific diet overlap and the degree to which …

Aspects of the biology of fish populations from the Medway Estuary, based on power station intake sampling with special reference to parasitism and pollution
… common species were investigated. The diets of plaice, Pleuronectes platessa L., flounder, Platichthys flesus (L.), whiting, Merlangius merlangus (L.) and pouting, Trisopterus luscus (L.) were monitored. Seasonal and/or age variations in food intake and feeding behaviour were considered in …
