Microbiological quality of fresh catfish raised in ponds fertilized with raw sterilized poultry manures
A total of 2,800 catfish (Clarias gariepinus) were stocked in fourteen (14) 5 by 4 m2 earthen ponds in NJFFR Integrated Farm, New Bussa, Niger State. Raw and sterilized poultry manure of 0.13 to 0.52 kg/m3 concentrations were used to fertilize the ponds with the unfertilized ponds serving as control. The following bacteria were isolated from the poultry manure; Escherichia coli, Aeromonas hydrophila, Salmonella typhi, Shigella dysenteriae and Staphylococcus aureus. The microbial loads of samples increased with increase in concentration of manure. The fish samples from the 0.13 and 0.26kg/m3 sterilized manure fertilized ponds had no count in their fish flesh unlike others. However, the fish from the control ponds had the least with 0.68 log10 CFU/g while that of fish harvested from 0.52 kg/m3 raw manure fertilized ponds had the highest with 2.24 log10 CFU/g. Pathogenic enteric organisms like S. typhi, S. dysenteriae and A. hydrophila were not present in the fish flesh of the fish from the sterilized manure and control samples. The study revealed that fish samples from sterilized manures were better in terms of microbial safety for fish productions; hence sterilized manure is recommended for use in fish production to ensure the microbial safety of the fish, handlers and that of the consumers.
