Abstract |
Studies of the effect of inorganic and organic mercury on trout indicated that uptake was primarily via the gills in non-feeding fish. Organic mercury entered fish at a faster rate than inorganic mercury. Exposure of trout to 10 micrograms Hg/l (methyl form) had no effect on the gill oxygen consumption measured in vitro or on the plasma electrolytes. The hematocrit index increased significantly. Studies of the metabolism of iron by normal and iron deficient trout (made deficient by bleeding) indicated that the liver, spleen, and head kidney are the major iron storage organs. Liver iron was reduced by bleeding whereas splenic iron was unaffected. In iron deficient fish more radioiron appeared in erythrocytes than in normal controls. Studies of isolated-perfused gills revealed the presence of both alpha and beta adrenergic receptors and the data obtained indicate the functional surface area of trout gills can be regulated by changes in perfusion pathway through the gills. Use of perfused gills appears to be a very sensitive model to detect deleterious action of pollutants on fish. |
