The study was designed to investigate the effects of frozen storage on the proximate composition and chemical indices of pike (Esox lucius) stored for a period of six months at À20°C. During storage the moisture, protein and fatty acid contents decreased and the ash, total volatile basic nitrogen (TVB-N) and peroxide value (PV) content increased significantly (P < 0.05). In the fresh samples the moisture, total protein and total lipid contents were 77.61%, 19.21%, and 2.3% respectively. At the end of the storage time the abovementioned parameters were measured as 75.98%, 16.95%, 0.9%, respectively. TVB-N and PV contents changed from 1.30%, 6.27, 0.18 in fresh samples to 2.21%, 15.12 mg/100 g and 1.73 meq o 2 kg À1 after six months frozen storage, respectively. Thirty fatty acids were found in pike fillets, with a higher percentage in fresh fish of polyunsaturated fatty acids (51.14%), saturated fatty acids (22.94%) and mono unsaturated fatty acids (22.61%). The PUFAs decreased to 31.67% at the end of the storage time. Although some changes in quality and nutritional value were observed in the pike fillets during frozen storage, the changes were within the acceptable range.U.S.

“…For this reason, Famoofo and Abdul 6 and Ajagbe et al 7 carried out biological assessments to determine the quality of populations of the species in different water bodies in Nigeria. Ikomi and Odum 8 in their studies give insight into the type of food consumed by Chrysichthys auratus in captivity, while Olele et al 9 probed into the chemical and biological properties of Chrysichthys furcatus from River Niger, Nigeria. All these efforts were made towards conservation and sustainable utilization of the stock.…”

Background and Objective: Knowledge of fish reproduction is crucial to survival and abundance for sustainable use. Thus, a study on the sex ratio, size structure and gonad somatic index (GSI) of Chrysichthys nigrodigitatus in Asejire Reservoir was conducted in Asejire Reservoir, Nigeria to provide information on aspects of reproductive biology for sustainable management. Materials and Methods:The 251 samples of Chrysichthys nigrodigitatus were randomly collected from fishers' catch for seven months covering the wet and dry seasons of 2022 to assess sex ratio, size structure and gonadosomatic indices following standard procedures. Data generated were analysed using descriptive and inferential statistics at α 0.05 . Results: Samples examined had a joint sex ratio of 1:1.5 indicating a more dominant female population across both seasons. The GSI value ranged from 0.53-9.75 (wet) and 0.31-10.69 (dry) while the correlation coefficient between the GSI and body weight was 0.45 (wet) and 0.20 (dry). The result revealed a positive correlation across all relationships except between the GSI and weight in the dry season. Conclusion: The study provides crucial reproductive insights for managing Chrysichthys nigrodigitatus and suggests exploring its aquaculture potential through additional research.
