“…Indeed, in the stations of watercourses with a predominantly coarse substrate, biological diversity was found to be greater than that of the stations of watercourses with a predominantly muddy substrate. These observations corroborate the work of Liwouwou et al, 2018 in the Rembo Bongo, Ogooué and Nyanga watercourses, which conclude that in the watercourses at the head of the watershed, the assembly of coarse substrate is favorable to the aquatic life and maintaining greater biological diversity, reflecting the good ecological quality of the environment (Biram à Ngon et al, 2018). As a living and feeding environment, the coarse substrate of watercourses constitutes, with plant supports and woody debris, a favorable place of life for many species making up aquatic biocenoses, which promotes storage or the circulation of water, dissolved substances, organic matter and living organisms.…”

Monitoring of water quality and distribution of some benthic macroinvertebrates was carried out in a few control watercourses in the Mefou watershed, from August 2022 to June 2023 with the aim of identifying some ecological factors that influence the distribution of benthic organisms in forest areas. The evaluation of granulometric and physicochemical quality was carried out following the appropriate methods and the collection of benthic organisms following the multihabitat approach. The analysis of the particle size parameters shows that the coarse fraction dominates all the points explored, although the beginning of siltation was observed in the middle part of the Abouda and Fam rivers. Physico-chemical analyses revealed a relatively stable environment with well-oxygenated water, low values of organic pollution indicator parameters and low and constant temperatures throughout the watersheds. The analysis of the biological structure shows a total of 8483 individuals collected, all belonging to the arthropod phylum and the insect class. From the orders obtained, Hemiptera dominate the benthic fauna with 6 identified families. The organisational structure of the benthic community was analysed through the calculation of diversity and fairness indices and allows us to affirm that the benthic macroinvertebrate community is diverse and well organised.

“…Au Bénin, les poissons Schilbeidae font l'objet de beaucoup de capture dans la région du bas Ogooué(Mbega, 2004). SelonLiwouwou & al. (2013), les poissons Schilbe représentent entre 33 et 40% de la biomasse des poissons capturés au Bénin.…”

Cette étude a pour objectif de contribuer à la connaissance de la diversité ichtyologique ainsi que le mode d’exploitation des poissons Schilbeidae (Siluriformes) pêchés dans le Pool Malebo (fleuve Congo) en R.D Congo. La récolte de poissons s’est faite mensuellement entre Février et Septembre 2019 dans quatre stations de pêche à l’aide des filets maillants (50 à 100 m de long et 2,5 m de hauteur et de 8 à 50 mm de mailles), des épuisettes (0,5 à 2 mm de mailles) ainsi que des palangres de 50 m de long portant des hameçons de n° 7, 10, 11 et 13. Des échanges ont été engagés avec les pêcheurs œuvrant dans les stations retenues en vue de déceler le mode d’exploitation de poisson Schilbeidae. Les résultats obtenus montrent qu’il y a une diversité de poissons de cette famille. Huit espèces (Schilbe mystus Linné, 1758 ; S. intermedius Rüppell, 1832 ; S. zairensis De Vos, 1995 ; S. congoensis Leach, 1818 ; S. marmoratus Pellegrin, 1926 ; Parailia congica Boulenger, 1900 ; P. occidentalis Pellegrin, 1901 et Pareutropius mandevillei Poll, 1900) regroupées en trois genres (Schilbe, Parailia et Pareutropius) ont été identifiées dans le Pool Malebo. Les poissons des genres Schilbe (62 %) et Parailia (25 %) sont les plus abondants. Au niveau des espèces, Schilbe mystus (261 spécimens), S. intermedius (107 spécimens) et S. zairensis (26 individus) sont les plus représentatifs. En terme de richesse spécifique, les stations de Kinkole (8 espèces et H’ = 1,42) et Kinsuka (7 espèces et H’ = 1,205) sont les plus diversifiées. En termes d’abondance, les mois de Juillet, Juin, Mai et Août sont les plus propices à la pêche des poissons Schilbe mystus, S. intermedius, S. zairensis et Parailia occidentalis. Les enquêtes réalisées ont montré que ces poissons sont exploités régulièrement et, présentent une grande valeur économique. Toutes les tailles de poissons sont retenues lors de la pêche pratiquée avec des engins non sélectifs, ce qui présage une exploitation irrationnelle de poissons Schilbeidae dans le Pool Malebo. This study aims to contribute to the knowledge of the ichthyological diversity as well as the exploitation mode of Schilbeidae fishes (Siluriformes) fished in the Malebo Pool (Congo River) in D.R. Congo. The harvesting of fish was done monthly between February and September 2019 in four fishing stations using gillnets (50 to 100 m long and 2.5 m high and 8 to 50 mm mesh), dip nets (0.5 to 2 mm mesh) as well as longlines of 50 m long with hooks of n° 7, 10, 11 and 13. Discussions were held with the fishermen working in the selected stations in order to identify the mode of exploitation of Schilbeidae fish. The results obtained show that there is a diversity of fish in this family. Eight species (Schilbe mystus Linné, 1758; S. intermedius Rüppell, 1832; S. zairensis De Vos, 1995; S. congoensis Leach, 1818; S. marmoratus Pellegrin, 1926; Parailia congica Boulenger, 1900; P. occidentalis Pellegrin, 1901 and Pareutropius mandevillei Poll, 1900) grouped in three genera (Schilbe, Parailia and Pareutropius) have been identified in the Malebo Pool. Fish of the genera Schilbe (62 %) and Parailia (25 %) are the most abundant. At the species level, Schilbe mystus (261 specimens), S. intermedius (107 specimens) and S. zairensis (26 individuals) are the most representative. In terms of species richness, the stations of Kinkole (8 species and H' = 1.42) and Kinsuka (7 species and H' = 1.205) are the most diverse. In terms of abundance, the months of July, June, May and August are the most favorable for the fishing of Schilbe mystus, S. intermedius, S. zairensis and Parailia occidentalis. The surveys carried out have shown that these fish are exploited regularly and have a high economic value. All sizes of fish are retained when fishing with non-selective gears, which indicates an irrational exploitation of Schilbeidae fish in the Malebo Pool.
