Evaluating Growth, Reproductive Indices and Environmental Adaptability of the Common Carp (Cyprinus carpio) in Mechraa Sfa Dam, Tiaret Region, Algeria

Author

Abstract

This study evaluated the health and growth patterns of fish in the Mechraa Sfa Dam, Tiaret, in 2022. Analysis showed slight allometric growth, with the b-value below 3, indicating asymmetry. Statistically significant hepato-somatic, gonado-somatic (P< 0.05) highlighted variations in liver condition, reproductive health, and body form. The condition factor averaged 2.0476±1.2356, reinforcing the asymmetric growth pattern. The environmental parameters recorded no effect on the biological indices, except for a positive correlation of GSI with pH and dissolved oxygen as well as HIS with orthophosphate (r˃ 0.5). These findings establish a baseline for assessing fish health, supporting future conservation and fishery management efforts in the region.
