Length-weight and length-length relationships for three endemic cyprinid species of the Aegean region (Turkey) with proposed standard weight equations.

Empirical standard weight equations and length-weight and length-length relationships were estimated for Barbus pergamonensis, Capoeta bergamae, and Ladigesocypris irideus, three endemic cyprinid species of Turkey that are still not widely studied. To the best knowledge of the authors, empirical standard weight equations for the three species and L-W parameters for L. irideus are given here for the first time. In this study, length and weight data for B. pergamonensis, C. bergamae, and L. irideus were collected throughout the watercourses of Muğla Province and were used to develop species-specific Ws equations. The results were for B. pergamonensis (total length [TL] range: 6-22 cm) log₁₀W_s= -5.713 + 3.718 log₁₀TL - 0.166 (log₁₀TL)³, for C. bergamae (TL range: 8-29 cm) log₁₀W_s= -5.224 + 3.311 log₁₀TL - 0.083 (log₁₀TL)³, and for L. irideus (TL range: 6-10 cm) log₁₀W_s= -13.298 + 12.116 log₁₀TL - 2.471 (log₁₀TL)³. This study also reported new maximum TLs for the three species, together with species-specific length-weight and length-length equations. [ABSTRACT FROM AUTHOR]
