Effect of Cobalt on Sperm Motility in an Endangered Trout Species, Salmo coruhensis

摘要: Experiments were designed to examine the in vitro effect of cobalt on sperm motility endangered trout species (Salmo coruhensis). Sperm samples diluted an immobilizing solution, and activated a motility-activation solution that was supplemented with at concentrations 1, 10, 100 1000 mg/L. The percentage motile duration determined. Cobalt 1–100 mg/L had positive compared control group, while concentration 1000 mg/L resulted decreases these parameters (p < 0.05). percentages 0, 83.33% ± 0.25%, 88.33% ± 0.34%, 89.00% ± 0.57%, 90.00% ± 0.87% 42.50% ± 0.45%, respectively; time durations over which remained 72.00 ± 0.63, 74.83 ± 0.28, 77.40 ± 0.47, 81.14 ± 0.78, 50.25 ± 0.67 s, respectively. This study has shown significantly enhanced (p < 0.05) 10 100 mg/L, relative controls, decreased
