|Title:||Studies on perispawning mortalities in brown trout (Salmo trutta L.) from Loch Leven, Kinross, Scotland|
|Publisher:||University of Stirling|
|Abstract:||Investigations into perispawning mortalities in the brown trout (Salmo trutta L) population of Loch Leven, Kinross, revealed that death occurred as a result of infection with a particular species of Saprolegnia diclina Humphrey type 1. Increased surface area of infection was correlated with a decrease in ion and protein content of the blood and was further reflected by changes in the electrocardiogram pattern. These changes were essentially a widening of the QRS complex with inflection of the RS component, changes consistent with a decrease in certain ions in mammals. Histological changes associated with sexual maturity and fungal infection are described and compared with changes resulting from the administration of androgens to brown trout.|
