Comparison of microbiological and proximate analysis of Synodontis nigrita, Chrysichthys nigrodigitatus and Mormyrus rume in Olomore market, Abeokuta, Ogun State, Nigeria
The study was carried out to compare the microbiological and proximate analysis of fresh Synodontis nigrita, Mormyrus rume and Chrysichythys nigrodigitatus sold at Olomore market, Abeokuta, Ogun State. This fish are always available at Olomore market and other market around Abeokuta and its environment. The protein, carbonhydrate, moisture, and ash of the fishes was based on the method of analysis of the Association of Official Analysis (AOAC:1990). Data for each sp. were subjected to analysis of variance (ANOVA). The Results show no significant difference in moisture content of Chrysichthys nigrodigitatus (70.99 ~c 1.09%), Mormyrus rume (67.30 ~c 4.08%) and Synodontis nigrita (67.33 ~c I.99%). The crude protein content of Chrysichthys nigrodigitatus (12.10 ~c 0.74%) Mormyrus rume ( 15.48 ~c 1.63%) and Synodontis nigrita (I0.73 ~c 0.61%). For carbohydrate content we have Chrysichthys nigrodigitatus (1.15 ~c 0.13%9), Mormyms rume (2.09 ~c 0.20%) and Synodontis nigrita (2.04 ~c 0.10%). Fat content of Chrysichthys nigrodigitatus (7.15 ~c 1.29%) Mormyrus rume (8.97 ~c I.9%) and Synodontis nigrita (8.62 ~c 0.89%) and for ash content of Chrysichthys nigrodigititus (6.33 ~c 0.69%), Mormyrus rume (4.89 ~c 0.21%) and Synodontis nigrita (8.85 ~c 0.27%). For crude protein there was different (p < 0.05) same with fat content, ash content, and carbohydrate content (p< 0.05) unlike moisture content and dry matter content which is (28.57 ~c 1.55%), (32.50 ~c 4.08%) and (32.67 ~c 1.99%) in Chrysichthys nigrodigitatus, Mormyrus rume and Synodotis nigrita. Result showed total bacteria count from (1.9 to 3.8 x 10<sup>6</sup> cfu/ml) from Chrysichthys nigrodigitatus while (2.8 to 4.7 x 10<sup>6</sup> ur cfu/ml) was obtained for Synodontis nigrita and (2.6 to 3.8 X 10<sup>6</sup>cfu/ml) for Mormyrus rume. The micro-organism isolated were pseudomonas spp; Escherichia spp; Klebsiella spp; omomls spp, Escherichia spp., Klebsiella spp., Staphylococcus spp., Proteeus spp. and Micrococcus spp. On biochemical characterization the following bacteria was isolated Pseudomonas spp., Escherichia spp., Klebsiella, spp. staphylococcus spp., Proteus Micrococcus spp.
