Comparative study on African catfish hypophysation indices using ovaprim and chicken pituitary gland extract (CPGE) was carried out. Sixteen (16) African catfish brood stocks between 1100 and 2300 g in ratio 2:1 and four (4) numbers of layer birds (Gallus gallus domesticus) between 1200 and 2200 g in ratio 1:3 were used respectively. The experiment was batched into “A” and “B”. Batch ‘A’ was placed on ovaprim while batch ‘B’ was placed on CPGE. An indoor hatchery vat, measuring 0.6096 m x 1.8288 m x 0.3048 m each was used for the incubation. Digital measuring kits were used to monitor water quality parameters and measurement of the brood stocks weights independently. Brood stocks on ovaprim and CPGE treatments had the following mean hypophysation indices in these order: fecundity (11100±7690 and 17760±13863), latency period (9.53±0.54 and 9.77±0.49), fertilization percentage (94.03±5.90% and 90.6±10.11%), hatchability percentage (75.6±0.81% and79.35±10.27%), number of eggs produced (5889±657.37 and 9403.33±589.80), total number of larvae hatched (4717.33±1111.0 and 7111.33±506.64), SGR (0.67±0.31 and 1.1±0.31), and survival rate (64.81±0.71 and66.24±2.19) respectively. There was no significant difference (p = 0.05) in the mean values of fecundity, latency period, fertilization and hatchability percentages in both treatments but there was significant difference (p ≤ 0.05) in number of eggs produced and total number of larvae hatched in both treatments. The water quality parameters were within the range for induced breeding techniques and there was no significant difference (p= 0.05) in both experiments. Both ovaprim and CPGE had excellent results from the induced breeding of Clarias gariepinus and yielded good results. Therefore, CPGE could be recommended from the view point of excellent results and its availability from chicken slaughter houses as against ovaprim which are imported.

Chemical Characters

The CYP family enzymes are broadly used as biomarkers because of their pattern of expression. This study describes the application of in silico tools to predict the physico-chemical characters of CYP1A protein from the catfish, Clarias gariepinus. The nucleotide sequence analysis of C. gariepinus CYP1A gene showed higher similarity with C. batrachus and reflected in the phylogenetic tree. The comparative modelling results showed this CYP1A protein was highly similar with the 3-D crystal structure of human Cytochrome p450 1A1 (PDB: 1BE3). The prediction results depicted that most of the amino acids formed alpha helix. The predicted pI was 9.10, hydropathycity was -0.226, exposed and buried residues were 61.67, 38.33% respectively. Ramachandran plot analysis showed that most of the amino acids falling on the favoured region and exhibited right- handed alpha helices as the most stable secondary structure. Some amino acids were also found to form loops to interconnect different helices. The CYP1A protein was predicted to be localized in the mitochondrion of the eukaryotic cell.

Aim. Nutrients analysis of wild and farmed raised African catfish (Clarias gariepinus, Burchell, 1822) were studied. The comparative work was carried out to find out if habitat could affect the nutrient composition of the fish. Study design: Five live C. gariepinus were obtained for three wild location and three fish farm each (n=30). One-way analysis of variance was use to examine the nutrients composition across the study locations. Methodology: Five individual fishes were randomly selected from the forty individuals in a population obtained from six locations. They were sacrificed and cut into three (tail, middle and trunk) chunks. These were oven dried at a constant temperature of 105ºC using oven model LCON53CF. The samples were later blend using electric blender and kept in airtight nylon for further analysis. Standard methods were employed in the analysis of body nutrients. Results: A significant difference was observed in proximate composition of C. gariepinus on dry matter bases. The moisture and lipids content were lower in wild C. gariepinus (5.16±0.07;15.27+0.08%) than farm raised (5.25±0.10%;18.54+0.08%). The average protein and ash contents in farm-raised C. gariepinus were significantly (p<0.05) lower (66.23+0.08%; 5.00+0.07%) than wild C. gariepinus (67.24+0.09%;9.06+0.07%). Organoleptic study revealed differences in taste between wild and farm raised C. gariepinus (p<0.05). The amino acids profile showed little disparity in quantity in wild and farm raised C. gariepinus. No significant difference (p>0.05) was noticed in the mean values of amino acids in wild (4.21) and farmed raised (4.16) C. gariepinus. The percentage of saturated fatty acids was higher (56.24%) in farmed raised C. gariepinus than the wild stocks (44.53%) unlike the unsaturated fatty acids that was higher in wild (79.46%) than the farmed raised (54.03%). Conclusion: The study revealed that wild fish possess some nutritional advantages over the culture C. gariepinus.

The nutritional qualities of wild and cultured Clarias gariepinus from Oba Reservoir, Ikose, Ogbomoso, Oyo State, Nigeria, and the cultured fish from the Department of Fisheries and Aquaculture, Oyo State Ministry of Agriculture and Mineral Resources, Ogbomoso, Oyo State, Nigeria, were evaluated. The proximate composition, mineral element composition and essential amino acids profile of the sampled fish species were evaluated using standard laboratory procedures. The results of the proximate composition was observed to be high in cultured population compared to the Wild and there was a statistical significant difference in the amount of crude protein, fibres, carbohydrate, fat/lipid, ash and moisture contents across the two sampled populations (Wild; 17.94 ± 0.19, Cultured; 21.06 ± 0.51), t = -5.738, p-value =0.001. Mineral element content showed maximum amount of copper (Cu), Lead (Pb), Manganese (Mn) and Iron (Fe) in Wild population than in their cultured counterpart while the amount of Cadmium (Cd) and Nickel (Ni) observed in Wild population were undetected. It was also discovered that all amino acid analysed were found to be higher in the cultured group compared to the wild. There were varied levels of significant correlations among all the measured amino acids contents across the two sampled populations. This study showed that the proximate composition, elemental contents and amino acids profiles of both the cultured and wild fishes varies significantly and the results proofed that the cultured fish sample were more nutritious than the wild population, therefore, good monitoring system of Oba Reservoir should be encouraged with strict vigilance.
