  Fish seed of the right quality and quantity remain a major challenge facing aquaculture in Nigeria. This study was conducted to evaluate the potentials for culturing the hybrid of Clarias gariepinus (♀)xHeterobranchus bidorsalis (♂) (Heteroclarias) to commercial size in earthen ponds. Three earthen ponds 0.02 hectares were stocked each with 330 fingerlings of Clarias gariepinus (♀)xHeterobranchus bidorsalis (♂) hybrid (popularly called Heteroclarias) on the 1st February, 2010. Mean weight at stocking was 7.50±1.50 g. The fish were fed 3% of their body weight two times daily with compounded artificial feed containing 45% crude protein. The changes in length and weight of the fish were measured fortnightly and the feed fed to the fish were accordingly adjusted to reflect the changes in weight. Temperature, dissolved oxygen, pH and total ammonia-nitrogen were measured in each pond. Survival rates, specific growth rate and condition factor were also determined. Survival at harvest (24 weeks after stocking) was 97.3% and the mean weight of the fish was 880±78.72 g (ranged, 610-1150 g). Standing crop at harvest was 282.48 kg/0.02 ha (14,124 kg ha-1). Growth of hybrid (Heteroclarias) was positively correlated with the number of weeks of the study (R = 0.9). Results demonstrated the potential of Heteroclarias for use in aquaculture and indicate that the fish species can be grown to commercial size within 24 weeks from fingerling stage under semi-intensive pond condition. The best time to selectively harvest the fish for maximum gain in terms of good growth and maximum profit on feed utilization is also 24 weeks.

  This study was conducted to assess the reproductive performance, growth rate and nutrient utilization capacities of pure breed Heterobranchus bidorsalis (H. bidorsalis ♀ x H. bidorsalis ♂) and its hybrid (H. bidorsalis ♀ x C. gariepinus ♂) (Clariabranchus) induced with synthetic hormone (ovaprim) and pituitary of male and female Heterobranchus bidorsalis. In this study, 3 female Heterobranchus bidorsalis, 3 male Heterobranchus bidorsalis and 3 male Clarias gariepinus were used for the experiment. One female H. bidorsalis induced with ovaprim produced eggs which were divided into two equal halves. Each half was fertilized separately by milt from H. bidorsalis and C. gariepinus to produce pure breed and hybrid, respectively. A similar crossing was done for the female H. bidorsalis induced with Male Pituitary Extract (MPE) and Female Pituitary Extract (FPE). Percentage fertilization and hatching rate of pure breed induced with ovaprim were significantly (p<0.05) higher than the other genetic crosses. The highest values for weight gain (5.46±1.58 g), average daily growth (0.39±0.11 g) and specific growth rate (1.04±0.16%/day) occurred in pure breed induced with MPE. The lowest values for these growth parameters were obtained in the hybrid induced with FPE. Feed intake, protein intake, feed conversion ratio and protein efficiency ratio varied significantly (p<0.05) among the treatments. This study has shown that the pure breeds and hybrids induced with ovaprim and MPE performed better than those induced with FPE. Therefore, they are recommended for commercial aquaculture.

  The growth of the aquaculture industry in Nigeria depends to some extent on the availability of fish seeds. This study was carried out to measure the optimum growth of Heterobranchus bidorsalis and the best time to crop under maximum utilization of feed in semi-intensive pond condition. Optimum growth performances of 330 fingerlings of artificially propagated Heterobranchus bidorsalis were investigated. The fingerlings were stocked in three 0.02 hectares earthen ponds on the 1st of February, 2010. Mean weight at stocking was 8.5±1.5 g. The fish were fed 3% of their body weight two times daily with compounded artificial feed containing 45% crude protein. Temperature, dissolved oxygen, pH and total ammonia-nitrogen were measured in each treatment. Survival rate, specific growth rate and condition factor of fish species were also determined. Survival at harvest (after 26 weeks) was 75.5% and the mean weight of the fish was 850±73.06 g. Standing crop at harvest was 10,580 kg ha-1. There was positive correlation (0.99) between growth of Heterobranchus bidorsalis and the number of weeks of growth study of the fish. Mean condition factor (K) was 1.24. Result demonstrated the potential of Heterobranchus bidorsalis for use in aquaculture. It also indicates that the fish species can be grown to commercial size within 26 weeks from fingerling stage under semi-intensive pond conditions. The best time to harvest the fish for maximum gain in terms of good growth and maximum profit on feed utilization is 26 weeks after hatching.

  The importance of seaweeds cuts across various environmental, ecologic, socio-economic benefits and services as food for man, in the phycocolloids and expanding phycosupplement industries, as sink for excess carbon dioxide and excess nutrients; for sustainable energy generation and as fossil fuel substitutes. In view of this, seaweeds could become an important economic niche for Nigeria and other coastal African countries provided adequate research is undertaken in studying their diversity, biochemical compositions and potentials for culture in order to harness the numerous opportunities which can be derived.

  The production of fish seed of good quality remains one of the major challenges of modern aquaculture in Nigeria and sub-Saharan Africa. This study was conducted to determine the survival rate, fertilization rate, growth performance and feed utilization of the reciprocal hybrids of Clarias gariepinus and Heterobranchus, bidorsalis. Two genetic crosses were made: C. gariepinus♀xH. bidorsalis♂ and H. bidorsalis♀xC. gariepinus♂. The experiment was conducted in two phases; the first phase was the artificial propagation of the fish species using synthetic hormone and rearing the fry for 14 days; the second phase was rearing the 14 days old fry for 35 days. The first phase of the experiment examined the survival of frys in each experimental unit (genetic cross) while in the second phase, growth and nutrient utilization were investigated. The result showed that the highest (%) fertilization (81.32±4.76%), hatching rate (73.89±4.45) and (%) survival (78.36±4.79%) occurred in H. bidorsalis♀xC. gariepinus♂ and the differences were significant (p<0.05). Percentage weight gain and specific growth rate were the two growth and nutrient utilization parameters that showed significant difference (p<0.05) between the two reciprocal hybrids. The result of this study shows that the reciprocal hybrids of C. gariepinus and H. bidorsalis can be used for commercial aquacultural practices.
