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),

Causes and consequences of recent degradation of the Magdalena River basin, Colombia

Limnology and Oceanography Letters, Volume 7, Issue 6, Page 451-465, December 2022., 2022
Abstract The Magdalena River in Colombia is one of the world's largest (discharge = 7100 m3 s−1) tropical rivers, hosting > 170 aquatic vertebrate species. However, concise synthesis of the current ecological and environmental status is lacking. By documenting the anthropogenic stressors impacting the river on time scales ranging from centuries to ...

Ultra‐acute exposure to cadmium does not impair whitefish sperm motility

Journal of Fish Biology, Volume 99, Issue 3, Page 1130-1134, September 2021., 2021
Abstract Cadmium (Cd) exposure can impair the traits of aquatic animals associated with reproduction. In natural lakes Cd is typically detected at concentrations below 0.001 mg l−1. The authors investigated the impact of ultra‐acute Cd exposure on sperm motility in European whitefish (Coregonus lavaretus).
