Age and growth of three species of Lake Victoria fish determined by means of otolith daily growth rings
Type: Journal Article
The sagittal otoliths of Lates niloticus, Haplochromis obesus, and Oreochromis niloticus from Lake Victoria were examined for daily growth rings using scanning electron microscopy. In the three species the increments were ...
Simulation of the effects of oxygen on food consumption and growth of Nile tilapia, Oreochromis niloticus (L.)
Type: Journal Article
Fish need oxygen for aerobic generation of energy for body maintenance, locomotion, feeding and biosynthesis. The rate of oxygen uptake of most fish is limited by diffusion through the gills, and gill surface area grows ...
