RELATION OF LENGTH, WEIGHT AND CONDITION FACTOR OF NILOTIC TILAPIA IN HIGH DENSITY CROPS

Abstract

This study analyzes the length-weight relationship and condition factor (k) of Nilotic Tilapia (Oreochromis niloticus) during the different stages or phases of its cultivation cycle, as well as determines other useful biometric variables for pattern analysis of the species’ growth. For this purpose, 2188 data were processed, obtained from three production processes under the same management conditions in a fish farming company located in the Maracayo district, municipality of Montería, Colombia. Data was collected using biometrics from the months of June through November, 2019. The results obtained when analyzing the length-weight relationship shows isometric growth in nilotic tilapia, with slight variation during the three stages of cultivation. The values of the condition factor K varied according to the phase, increasing as individuals’ weight grew. The correlation of some morphometric variables with environmental variables fundamentally associated with water quality was analyzed.
