dc.description.abstractInvestigation into some aspects of the water quality and proximate composition of freshwater crab sudanonautes kagoroensis (Cumberlidge, 1991) in kubanni Reservoir, Zaria, Kaduna State, Nigeria was carried out between February and August 2010 using APHA and AOAC standard methods. Analysis of Variance (ANOVA) was used to compare the means of the physico-chemical parameters. Moisture, ash, fat, protein and carbohydrate content of the various component parts were first analysed by one-way analysis of variance (ANOVA).Where a significant difference (P≤0.5) was observed, Duncan Multiple Range Test was used to separate the means. Students T Test was used to test for significance in the condition factor of Sudanonautes kagoroensis between sexes with respect to seasons. The study revealed that the mean values of air temperature were (29.57oC±0.26 and 28.89oC ±0.24),water temperature (28.57oC ±0.26 and 26.78oC ± 0.19), dissolved Oxygen (6.49 ± 0.15 mgL-1 and 6.78 ± 0.11mgL-1), electrical conductivity (164.33 ± 2.75uScm-1 and 67.20 ± 2.59uScm-1), Water hardness (65.39 ± 1.27mgCaCO3L-1 and 69.95 ± 1.15mgCaCO3L-1), alkalinity (59.03 ± 0.75 mgCaCO3L-1 and 43.93 ± 1.14 mgCaCO3L-1 ), pH (10.07± 3.01 and 7.03± 0.07), P04-P(3.20± 0.12mgL-1and 3.86 ± 0.12mgL-1) No3-N (2.63 ± 0.11ugL-1 and 2.74 ± 0.11mgL-1) and TDS (68.83± 1.17 mgL-1and 43.67 ± 1.66 mgL-1) for dry and wet seasons respectively. Significant difference (P ≤ 0.05) was observed in the mean values of water temperature, electrical conductivity, hardness, phosphate phosphorus and total dissolved solids. There was no significant difference (P ≥ 0.05) in the air temperature, dissolved oxygen, alkalinity, pH and nitrate nitrogen. The study revealed that the water quality parameters was in the range of W.H.O recommended standard for the survival of aquatic organisms. It also revealed that crab was wide spread and abundant across the various stations of the reservoir. Abundance in terms of number was more during the wet season (140) than dry season (95), with maximum peak in the months vii of July and August (49 and 47) respectively. The Condition Factor (K) revealed that crab species were in good health condition. The male to female ratio showed that the females were greater in number than the males in the months of April, June, July and August. While the months of February and March had a higher male to females ration. The proximate composition analysis of crab revealed significant difference (P ≤ 0.05) in protein and lipid contents of the various body parts analyzed. There was no significant difference (P ≥ 0.05) in the carbohydrate, ash, and moisture contents of species from different locations. It is concluded that S. kagoroensis contained appreciable amounts of protein in line with WHO recommended values to be incorporated into human diet.en_US
