    Description: The work was carried out using 48 samples of smoke-dried African catfish (Clarias gariepinus). Twelve samples each were obtained from high level market, Wadata market, Wurukum Market and North bank market respectively. Different media (SDA, MSA, EMBA, N.A, MCA), gram reaction and biochemical tests were carried out to confirm the presence of the pathogenic bacteria. There was a strong correlation between the bacterial count and water activity of the fish for all bacterial isolates. The micro-organisms isolated were Aspergilus niger, Mucor spp, Salmonella spp, Escherichia coli and Staphylococcus aureus which were indications of contamination from surrounding environment.

    Description: The shrimps were collected from three sampling sites: on the River Benue at Makurdi, Benue state, on the River Niger at Jebba and Lokoja and Idah at Kogi state from January to April, 2011. Macrobrachium felicinum and Atya gabonensis were sampled during this period, with Atya gabonensis occurring more abundantly. Condition factors of freshwater shrimps Atya gabonensis from the two water bodies in Nigeria range from 1.875for species in Jebba in March to 3.330 for Lokoja in March. The parameter ”b” of the length - weight relationship of the fresh water shrimps are less than three (rangingfrom 1.0233 for species from Lokoja in April to 2.7717 for species from Makurdi in Feburary). These values suggest negative allometric growth. The length frequency of freshwater shrimps sampled shows that peak populations of length groups occurred in April for species from Jebba and Makurdi while peaks occurred in January for species from Lokoja.Peak frequencies were observed in length of 4.0 - 5. 4cm and 8.5 - 9.9cm in January as well as 5.5 -6.9cm for species from Lokoja and in the group of 5.5 - 6.9cm in April for species from Makurdi and 7.0-8.4cm in April for both Makurdi and Jebba.
