Length-weight relationship and condition factor as an indicator of growth and feeding intensity of Sea bream (Sparus aurata L, 1758) given feed with different protein contents

The aim of this study is to investigate the relationship between the length-weight and the condition factor of gilthead sea bream (Sparus aurata L., 1758) fed with three types of feed with different levels of crude protein (A: 38% Crude Protein (CP) and 18% Crude Lipid (CL); B: 42% CP and 18% CL; and C: 45% CP and 18% CL). The length-weight relationship of the fish in groups A, B and C was determined as W=0.051*TL^2.63, W=0.046*TL^2.67 and W=0.046*TL^2.68 respectively and there was no statistically significant difference between the groups (p>0.05). There was negative allometric growth in all experimental groups. The lowest mean value in the groups according to Fulton's condition factor (CF) was found in group B (1.66±0.17), and the highest mean value was found in group C (1.71±0.18). It was determined that there was no statistically significant difference between the groups (p>0.05).
