“…This value is also lower in other species of the Clariidae family [8] in individuals of Clarias gariepinus (0.45) and Heterobranchus bidorsalis (0.44). On the other hand, it is higher than that observed in populations of Clarias gariepinus from Lokoja (0.12) and Asejire (0.40) in Nigeria [21]. The difference could be explained by the number of markers used and the level of diversity within the fish samples collected.…”

Clarias anguillaris is a wild species found in River basins in Mali. It is the species most commonly used in fish farming in community stockings. However, it excites little study on the genetic diversity of this species in the natural environment in Mali. The present study focused on the genetic diversity of Clarias anguillaris from the Bakoye River, a tributary of the Senegal River in Mali. A total of (8) microsatellite markers were applied to 47 samples taken at random from the River. The markers were Cga02, Cga03, Cga06, Cga10, Cba11, Cba19, Cba20 and Cma12. The number of alleles, the number of genotype, genetic diversity, Polymorphism Information content (PIC), observed and expected heterozygosity were determined. The results showed that the number of alleles ranged from 1 to 7, with an average of 4.25 per locus. The mean rate of observed heterozygosity was 0.34 lower than that of expected heterozygosity which was 0.48 indicating nonconformity of the Hardy-Weinberg equilibrium. The allele frequency ranged from 0.35 at the Cba19 locus to 1 at the Cba11 locus, with a mean of 0.62. Genetic diversity ranged from 0 for Cba11 to 0.75 for Cba19. The markers Cga02, Cga03, Cga06, Cba19, Cba20 and Cma12 were polymorphic with an average peak of 0.42. The phylogenetic tree presented two groups of genotypes showing diversity within the species. Group I comprised 60.42% of individuals and group II presented 39.58% with 3 subgroups (A, B and C). The genetic distance (0.05) indicates little differentiation between individuals.

A study was conducted at the Lay-Joy Fish Farm, Billiri, Gombe State Nigeria to evaluate the carcass proximate composition of Clarias gariepinus fingerlings fed different levels of Maca root powder as Phyto - additive. Five (5) isonitrogenous (40% crude protein) and isocaloric (1,732kcal kg-1 gross energy) diets were formulated, where Maca root powder in form of Phyto - additive was incorporated at 0.0g/100g (TM0), 0.25g/100g (TM1), 0.5g/100g (TM2), 0.75g/100g (TM3) and 1.0g/100g (TM4) inclusion levels, diet without Maca root powder (TM0), served as the control diet. The formulated diets were fed to Clarias gariepinus fingerlings (n = 300, 10.0±0.00g) in fifteen (15) rectangular white plastic tanks (n = 20) at a fixed feeding rate of 3% body weight twice daily between the hours of 8:00 - 9:00 am and 4:00 - 5:00 pm at regular interval and adjusted after every two (2) weeks of sampling for a period of twelve (12) weeks. Proximate analysis was carried out on a sample of the Clarias gariepinus fingerlings at the beginning of the experiment, at the end of the experiment three (3) Clarias gariepinus from each treatment were sacrificed and the carcass subjected to proximate analysis. Carcass crude protein value was highest in fish fed diet TM3 (72.00±1.32%) and least (67.80±1.96%) in the fish fed the control diet (TM0), carcass crude lipid value was highest in fish fed diet TM3 (14.70±1.19%) and least (14.07±2.45%) in the fish fed control diet (TM0), while the carcass crude fibre value was highest in fish fed control diet (TM0) (0.47±0.03%) and least (0.36±0.07%) in the fish fed diet TM3, carcass moisture value was highest in fish fed diet TM2 (1.64±0.07%) and least (1.41±0.04%) in the fish fed diet TM3, carcass ash value was highest in fish fed diet TM2 (11.15±2.03%) and least (10.00±1.67%) in the fish fed diet TM3 and the carcass nitrogen-free extract value was highest in fish fed control diet (TM0) (5.50±0.76%) and least (1.53±0.73%) in the fish fed diet TM3. The incorporation of Maca root powder as a Phyto-additive into the diet of Clarias gariepinus had no effect on the carcass proximate quality. Although there was a significant difference (p<0.05) in the carcass proximate composition of the Clarias gariepinus, no clear trends were noticed. Feeding Clarias gariepinus fingerlings with Maca root powder at 0.75g/100g feed inclusion level as Phyto - additive is recommended. However, further research should be carried out on other Phyto - additives on their efficacy in determining the carcass proximate composition of Clarias gariepinus.
