“…Such haplotype and nucleotide diversity combinations are characteristic of populations that have all experienced rapid population expansion after a period of low effective population size (Grant and Bowen, 1998;Chen et al, 2004;Ball et al, 2007;Liu et al, 2009).

“…The European and North American cyprinids have been genetically characterized (Gilles et al, 2001;Turner et al, 2004). More recently, Muwanika et al (2012) used mitochondrial control region and cytochrome b sequences to study genetic diversity in Labeobarbus species in the Lake Victoria and Albertine basins in Uganda, and reported the presence of two divergent Barbus lineages in the Lake Victoria region. Due to high levels of sequence polymorphism, the control region is useful in population diversity studies (Chen et al, 1998).…”

Genetic diversity and population structure of the endangered ripon barbel,Barbus altianalis(Boulenger, 1900) in Lake Victoria catchment, Kenya based on mitochondrial DNA sequences

Summary Approximately 850 bp of the mitochondrial control region was used to assess the genetic diversity, population structure and demographic expansion of the endangered cyprinid Barbus altianalis, a species known to be potamodramous in the Lake Victoria drainage system. The 196 samples taken from the four main rivers draining the Lake Victoria catchment (Nzoia, Yala, Nyando and Sondu–Miriu) yielded 49 mitochondrial DNA haplotypes; 83.7% thereof were private haplotypes restricted to particular rivers. The overall mean haplotype diversity was high (0.93663 ± 0.008) and ranged between 0.566 (Sondu – Miriu) and 0.944 (Nzoia). The overall mean nucleotide diversity was low (0.01322 ± 0.00141), ranging from 0.0342 (Sondu – Miriu) to 0.0267 (Nzoia). Population differentiation tests revealed strong and highly significant (P ≤ 0.001) segregation of populations in the four river basins. FST values among the four river‐based populations ranged from 0.05202 to 0.44352. The samples formed two main haplotype networks based on a 95% parsimony criterion, each exhibiting a strong signature of past population expansion. The smaller network was restricted to the River Nzoia, whereas the larger network contained representatives from all four rivers; within this the central haplotypes were found in more than one river, whereas the peripheral haplotypes tended to be river‐specific. The degree of population differentiation and the number of river‐specific haplotypes are too high to be explained by recent anthropogenic impacts alone and suggest that the species has probably existed in the Lake Victoria catchment as two populations: the now ‘extinct’ migratory population and the extant river restricted non‐migratory populations.

“…Multi-modal and more ragged distributions are a signature for more stable populations (Rogers & Harpending, 1992), reported in a number of fish taxa including Labeobarbus spp. Rüppell 1835 (Muwanika et al, 2012), Barbus altianalis (Boulenger 1900) (Chemoiwa et al, 2013) and C. batrachus (Lee & Sulaiman, 2015). LKG, however, showed a uni-modal and less ragged distribution, while LNG had a multi-modal and more ragged distribution, suggesting a recent population expansion in LKG, while LNG was a stable population.…”

In order to improve the conservation and sustainable utilization of the African catfish Clarias gariepinus of the Yala Swamp in Kenya, genetic diversity and population structure of Lakes Kanyaboli and Namboyo populations of the species were studied using DNA sequences of the mitochondrial D-loop control region. Genetic diversity inferred as haplotype and nucleotide diversities and number of singletons and shared haplotypes was higher in the Lake Kanyaboli population (LKG) than the Lake Namboyo population (LNG) of C. gariepinus. Thirty-one haplotypes were inferred, of which 25 (80·6%) were private or singletons, while only six (19·4%) haplotypes were shared between LKG and LNG. Both populations were differentiated, with F value that was significantly different from zero (P < 0·05). Two clusters were inferred both from the maximum likelihood tree and the spanning networks of phylogenetic relationships of haplotypes. Mismatch distribution for total sample was multi-modal but individually, distributions were uni-modal in LKG, but multimodal in LNG. The mean ± s.d. raggedness index for both populations was 0·085 ± 0·098 and not significantly different from zero (P > 0·05). Individual raggedness indices were 0·015 and 0·154 for LKG and LNG respectively. Fu's F was negative for both populations, with LKG recording -14·871, while LNG had -2·565, significantly different from zero for LKG (P < 0·05), but the value for LNG was not significant (P > 0·05). Tajima's D was negative for both populations, with LKG recording -1·734, while LNG had -1·136. Standardized square differences (SSD) were 0·001 for LKG and 0·048 for LNG and non-significant between them (P > 0·05). Values between all populations were also not significantly different (P > 0·05), mean ± s.d. SSD 0·025 ± 0·033.
