Synthèse Bibliographique sur des Paramètres Biologiques et Zootechniques du Poisson-chat Africain Clarias gariepinus Burchell, 1822

Abstract

This review article set out the inventory of the various scientific and technical contributions on the biological and zootechnical parameters of the catfish Clarias gariepinus. Several years of research shows that Clarias gariepinus is of great importance in fisheries and aquaculture in Africa and around the world, judging by the wealth of knowledge produced. The information provided in this review was collected from scientific articles, books and handbooks, technical reports, thesis, dissertations, and proceedings. The authors, through an inventory of the various scientific and technical contributions from 1971 to 2017, reported the biological characteristics of C. gariepinus, its diet and nutrition, its reproduction, its growth performance, its breeding systems and devices and some diseases to which it is subject. The biological characteristics of the African catfish were analyzed based on its description, taxonomic classification, habitat, ecological requirements and geographic distribution. The diet of the species has been addressed within its natural environment, in rearing and through nutritional needs and constraints. Reproduction of the species includes, age at first sexual maturity, incubation

Biological impact of in-situ exposure of catfish (<i>Clarias gariepinus</i> Burchell, 1822) to agricultural pesticide residues in the Tabalak pond

“…According to the synthesis of Géoffroy et al (2019), the values obtained are within the limits tolerated by Clarias gariepinus, notably from 8 to 35°C for temperature; between 6 and 9 for pH. This species adapts well to low dissolved oxygen levels ranging from 6.5 to 8 mg/l or even 3.5 mg/l (Eding and Kamstra, 2001;Brougher et al, 2005).…”

Human Endoparasites Present in the Digestive Tracts of Two Species of Cichlidae Fish: Oreochromis Niloticus (Linnaeus, 1758) and Tilapia Tholloni (Sauvage, 1884) Caught in the Malebo Pool (Congo River), D.R. Congo

“…The presence of the different species of endoparasites identified in the digestive tract of fish Oreochromis niloticus and Tilapia tholloni is explained by the ingestion of water and food contaminated by different types of the parasites in the fish food chain (Edéa et al, 2019). Fish are intermediate hosts for most endoparasites (Nchoutpouen & Fomena, 2011;Koné, 2015;Falaise, 2017).…”

“…This can result in a decrease in immune system activity, which can lead to the sudden onset of disease. Fry and juveniles are the most vulnerable; they need to develop their immunity (Edéa et al, 2019).…”
