Proximate analyses of some selected fish species in lake Geriyo, Yola, Adamawa state, Nigeria

Abstract

Crude protein, crude lipid and moisture content were determined from five fish species (Oreochromis niloticus, Clarias lazera, Lates niloticus, Citharinus citherus and Synodontis clarias) in both wet and corresponding dry samples. Standard analytical methods were used. Oreochromis niloticus had the least crude protein content (11.21% and 13.26%) in the wet and dry samples respectively. Lates niloticus had the highest crude protein content of 12.9% and 16.11% in the wet and dry samples respectively. There was no significant difference at P>0.05 between dry and wet sample and between the five species of fish sampled. Similarly, crude lipid content for O. niloticus was the lowest (3.0% and 3.4%) for wet and dry samples respectively. While Synodontis clarias showed the highest lipid content 5.6% and 13.1% for wet and dry samples respectively. Percentage moisture content was measured and O. niloticus showed the highest value of 82.08% while Synodontis clarias showed the lowest value of 65.78%. There was no significant difference at P > 0.05 between moisture content and all the five species of fish sampled.
