Reproductive Biology of the Hybrid Coptodon guineensis x Coptodon zillii within Two Marginal Lagoons Invaded by Macrophytes in South Eastern of Côte d`Ivoire

Hybrids of Coptodon guineensis x Coptodon zillii are omnivorous species with a phytophagous tendency found in most of water bodies of Côte d`Ivoire. This study aims to better understand its reproductive biology and possible influence of macrophytes on the breeding season. A total of 608 fish were ca...

Zusammenfassung:Hybrids of Coptodon guineensis x Coptodon zillii are omnivorous species with a phytophagous tendency found in most of water bodies of Côte d`Ivoire. This study aims to better understand its reproductive biology and possible influence of macrophytes on the breeding season. A total of 608 fish were caught monthly from September 2017 to August 2019. The overall sex-ratio showed significant predominance of females in Ono (1:1.37; χ² = 7.10; P
