Length-Weight Relationships of Luciobarbus pectoralis from the Menzelet Dam Lake of Kahramanmaras
M. Őzcan and U. Ispir
 
Abstract: Length-weight relationships are of great value in fisheries research as they are essential to convert length-frequency data into accurate populations estimates and are so often used in stock assessment methods. In this study, the length-weight relationships by sex of the Luciobarbus pectoralis population living in Menzelet Dam Lake (Kahramanmaras) were examined. Fish were caught with gillnets. A total of 150 samples were collected and analyzed. The length-weight relationship was estimated using the linear regression model W = aLb and condition factor, (K) determined using the equation K = 100.W/L3. Total length of samples ranged between 16.50-20.60 cm (male), 15.50-21.00 cm (female) and weight 30.81-61.64 g (male), 23.87-75.65 g (female) for L. pectoralis. The length-weight relationship of fishes were found as W = 0.067L1.778 for all specimens, W = 0.039L2.418 for male and W = 1.063L1.228 for females. Negative allometric growth was recorded for both sexes. The condition factor were varied as 0.731 (all individuals), 0.729 (male) and 0.732 (female) in L. pectoralis. The difference of length-weight relationship between L. pectoralis was not statistically significant (p and gt; 0.05). This study, in future has provided baseline information on the LWR and K of L. pectoralis that would be useful for fish biologists and managers to adopt the adequate regulations for sustainable fishery management in the natural water.
