Hydropower effects on Prochilodus magdalenae (Prochilodontidae) reproduction: evidence from endocrine response

Efectos de la generación de energía hidroeléctrica en la reproducción de Prochilodus magdalenae (Prochilodontidae): evidencia de la respuesta endocrina

Objective. Describe the endocrine response associated with the reproduction of a tropical potamodromous fish under changes in the flow discharge produced by hydropower in an Andean. Materials and methods. We analyzed Prochilodus magdalenae reproduction in individuals from two sectors of a Neotropical river basin: one with the natural flow and the other with a regulated hydrological regime. Results. In the sector of the basin with the natural flow we found that the production of hormones related with fish reproduction (FSH and LH) was correlated with the gonadosomatic index, while in fish experiencing hydropeaking due to hydroelectric operation no such correlation was detected. Conclusions. Hormone production associated to reproduction of the Potamodromous fish was sensitive to changes in water level and discharge. Then, fish exposed to hydropeaking would be receiving ambiguous stimuli that affect hormone production, reproduction synchronization with environmental cues, and ripening, which are essential for reproductive success.
