Length-Weight, Length-Length Relationships and Condition Factor of Picarel, Spicara smaris (Linnaeus, 1758) Sampled from Aegean Sea and Black Sea

Abstract

In this study, length-weight relationship (LWR), length-length relationship (LLR) and condition factor (K) of Spicara smaris (Linnaeus, 1758) collected from Aegean Sea and Black Sea during 2023-2024 fishing season were determined. A total of 116 samples (Aegean Sea N=56, Black Sea N=50) were obtained from commercial fishermen. The mean (±SD) total length and weight of samples varies between 15.47±0.98 cm, 34.82±6.45 g, and 12.35±1.40 cm, 20.01±8.93 g for Aegean and Black Sea, respectively. The slopes (b values) of the total length–weight regressions indicated (-) negative allometric growth to (+) positive allometric growth in localities. In addition, LLRs were calculated by using the linear regression model. LLRs were also highly significant (P
