Effects Of The Toxins Of The Ectoproct, Lophopodella Carteri, On Oxygen Consumption In Gill Tissues Of The Bluegill, Lepomis Macrochirus, Barbara Harper Green
Master's Theses
Large and small bluegill, Lepomis macrochirus, were exposed to homogena tes of Lophopodella carteri, an ectoproct that contains substances toxic to some gilled vertebrates. Oxygen consumption tests on the excised gill tissues of the bluegill indicated that the ectoproct toxins caused a lowering of oxygen consumption of the gill tissues. Oxygen consumption of the gill tissues of the smaller fish was reduced to a greater extent than that of larger fish. An inverse relationship was found be tween the temperature of the medium and the period of time for death to occur. It is proposed that the toxins cause physiological …

Effects Of The Toxins Of Lophopodella Carteri (Ectoprocta), On Blood Lactate And Electrolytes Of Lepomis Macrochirus (Bluegill), Robert Fisher Dance
Master's Theses
Specimens of bluegill (Lepomis macrochirus) were exposed to homogenates of Lophopodella carter, an ectoproct that contains substances toxic to some gilled vertebrates. The homogenates caused significant decreases in blood Na+ and Cl - and a significant increase in lactate. Potassium levels were unaffected. It is proposed that these changes in blood. properties were caused by damage to ion transport mechanisms of the gill epithelium.
