Abstract
Over a five year period experiments on rainbow trout indicated that exposure to chromium and to forced exercise caused a transient increase in plasma cortisol. Exposure to ammonia (a) caused a decrease in the rate of total nitrogen excretion and in ammonia excretion (b) caused some histopathological changes in trout gills but oxygen transport by hemoglobin was unaffected (c) caused a very slight increase in urea excretion by trout but a very significant rise in goldfish. Hyperexcitability observed in ammonia-exposed trout was not noticeable in the more resistant goldfish. Ammonia may kill fish by prevention of excretion of normal amounts of endogenous ammonia. Experiments with isolated-perfused gills of trout have shown among other things that (a) gill blood flow patterns are significantly affected by epinephrine (b) when perfused with Ringer solution there was a small but significant loss of sodium into the bath solution (c) perfusion fluid sodium and epinephrine appear to control sodium uptake by the gill (d) transfer of dieldrin into the vascular system occurred only when plasma protein, or more probably plasma lipoprotein was present in the perfusion fluid (e) short term exposure to dieldrin, rotenone, malathion and MS-222 reduced perfusion flow rate through isolated gills but exposure to 1 mg/L methoxychlor was without effect. Decrease in flow rate correlated well with lamellar perfusion. (Author)
