Antimicrobial activities of plants can also be explored using their different parts because they abound more in some of these parts than others. Extracts (hot water, cold water and ethanolic) of black pepper (Piper guineese) were used to preserve catfish (Clarias gariepinus) post-slaughter by dipping in separate bowls. The leaf extracts were more effective and ethanol the best solvent of extraction. Ethanolic extract of the leaves extended the shelf life of the fish from 20hours in the unpreserved sample to 36hours; it was followed by the ethanolic extract of the seeds (32hours). This observation makes black pepper seeds and leaves extracts useful natural preservatives for fish.
