A comparison of red-cell fragilities of electronarcotized and chemically anaesthetized freshwater bream, oreochromis mossambicus

A comparison of hematology, plasma chemistry, and injuries in Hickory shad (Alosa mediocris) captured by electrofishing or angling during a spawning run

“…Fish collected by EF in this study had significantly lower RBC, HGB, and PCV values compared to angled fish, which was likely the result of increased hemolysis. Exposure to certain electrical currents may increase the osmotic fragility of shad RBC compared to the stress related to angling . Electric currents may disrupt the membrane permeability and Na/K pumps in RBC resulting in erythrocyte swelling (eg, increase in MCV) and increased cell lysis .…”

“…Exposure to certain electrical currents may increase the osmotic fragility of shad RBC compared to the stress related to angling . Electric currents may disrupt the membrane permeability and Na/K pumps in RBC resulting in erythrocyte swelling (eg, increase in MCV) and increased cell lysis . Moderate effects of EF may result in increased PCV but not HGB if RBC swelling occurs without marked hemolysis.…”

“…41 Electric currents may disrupt the membrane permeability and Na/K pumps in RBC resulting in erythrocyte swelling (eg, increase in MCV) and increased cell lysis. 41 Moderate effects of EF may result in increased PCV but not HGB if RBC swelling occurs without marked hemolysis. However, EF may also not be accompanied by any PCV or HGB changes.…”
