“…Th is agrees with Kara et al (2011) who reported that morphological diversity among fi sh populations in diff erent habitats may not only be caused by genetic factors but also by environmental factors. Also, the multivariate analysis of variability in traits of Heterobranchus bidorsalis from three locations in Nigeria as reported by Agbebi et al (2009) indicated that fi sh from Gboko (Benue State) was characteristically separated from those obtained from Onitsha (Anambra State) and Jos (Plateau State). It was thus concluded that Gboko strains were unique and distinct.…”

-Th e study determined the variation in the morphological and meristic features among four populations of Clarias gariepinus Burchell, 1822 obtained from Owena Dam and River Oluwa in Ondo State and Rivers Omo and Ogbere in Ogun State, both in Nigeria. A total of ninety fi ve (95) and one hundred and twenty (120) fi sh specimens collected from Ondo and Ogun states respectively were measured using standard procedures and the results were analysed using Analysis of variance and multivariate analyses. Th e results obtained from the ANOVA and Principal Component Analyses of Clarias gariepinus from the four populations revealed heterogeneity for most of their characters. Th erefore, the morphological diff erences between the wild African catfi sh found in Ondo and Ogun state populations could be linked to genetic diff erences or environmental factors or a combination of both factors. Hence, this study concluded that the populations are diff erent which could imply high genetic diversity if molecular marker techniques are employed in further studies.

“…Although this species is exploited for table fish or for culture system stocking, there is a general lack of knowledge on the genetic variability of the different strains farmed in different parts of Cameroon [26]. According to [8], the culture of hybrids without proper genetic and economic evaluation rather invites more problems in the aquaculture sector. Proper identification is very crucial for proper fisheries assessment and management programmes.…”

Wild Clarias fish species are used for aquaculture in Cameroon, but information on their characterization is limited and mislabelling is rife. The purpose of this study was therefore to characterize wild and cultured Clarias fish specimens from Cameroon. Twenty-six (26) morphometric features, 3 meristic counts, some morphological observations and the cytochrome oxidase subunit I (COI) gene were used for the characterization. Based on gill raker count (GRC), specimens were separated into two principal groups. One group was tentatively identified as C. gariepinus and the second group as C. jaensis. However, because of the discrepancy in pectoral spines serration, the second group was referred to as C. aff. jaensis. Clarias gariepinus from Nkam and Mezam Rivers possessed the crescent vomerine while the cultured stock had interrupted vomerine and those from the Mungo River had both forms of vomerine. Based on phylogenetic tree, C. gariepinus from Mungo River was more diverse and ancestral compared to the other populations. Genetic identity of C. aff. jaensis with GenBank references was 92-94%. So the exact identity of the species remained unclear. Further studies are therefore needed to determine if these sequences represent an isolated branch of C. jaensis or if they belong to another species.
