Sperm Quality of Bocachico (Prochilodus magdalenae) Subjected to Acute Exposure to Cadmium and Lead

Turkish Journal of Fisheries and Aquatic Sciences
Heavy metal contamination, particularly cadmium (Cd) and lead (Pb), threatens aquatic ecosystems in Colombia. This study evaluated the acute effects of Cd, Pb, and their combinations on sperm quality of the vulnerable endemic species Prochilodus magdalenae. Treatments included three Cd doses (0.2, 0.8, 1.4 μg/kg), three Pb doses (2.0, 8.0, 14.0 μg/kg),
