Abstract

The study compared and assessed the diet and condition factors of two fish species, Oreochromis leucostictus and Cyprinus carpio, in Lake Naivasha. Fish samples were collectedmonthly using gill nets (35-70 mm mesh size) from July to December 2013. Stomach contents of allthe specimens were analysed using the point method. Results indicated that DETRITUS was the mostabundant food item in the diet of both O. leucostictus and C. carpio accounting for 50% and 63%, respectively, while benthic macroinvertebrates contributed the least with each fish having 2%.Rooting and digging behaviour of the carp probably led to both C. carpio and O. leucostictusingesting the suspended DETRITUS as their main source of food with C. carpio outcompetingO. leucostictus due to its prolific nature and better adaptability to benthic conditions. Fulton’scondition factor of all the fish samples had values of>1. A comparison of the two fish species showedC. carpio had a condition factor of 1.51 while O. leucostictus had 1.32. The higher condition factorof C. carpio in Lake Naivasha is an indication that the fish have better tissue energy reserves, greaterreproductive potential and higher survival rates compared to O. leucostictus with a lower conditionfactor.
