Inventory of fish caught by enclosure fishing in Sud-Ubangi (DR Congo)

Abstract

The aim of this study was to inventory the different fish species fished by using enclosure “Ndobo” in the Bomboma sector, to detect potential breeding species. The study found that 19 fish species belonging to 13 genera and 10 families dominated by Claridae with 31.6%. Only 6 species (about 31.6%) are already breeding by the pisciculturist. From an economic point of view, 3 listed species are among the species commonly bred in Democratic Republic of Congo, namely Parachanna obscura, P. insignis and Clarias gariepinus. Physical form (dimension et weight) and organoleptiques observations makes three species potential candidates for fish farming: two of Clarias genera namely C. sp (Limongo in Boba or Ngolo in Lingala) and C. sp (Okolo in Boba or Ngolo en Lingala) and one of Clariallabe genera: C. sp. (Motepa in Boba/Mongbangele in Lingala). Hence, there is a need to domesticate and to bred in ponds these species and evaluate their economic and zootechnic performances. That will enable to enrich piscicultural fauna with new species and then to diversify the fish production.
