Length-Weight Relationships of Four Symphodus Species (Pisces: Perciformes) From Eastern Black Sea (Turkey)

Abstract

This study provides the length-weight relationships of four fish species that belong to the Labridae family from the Rize coast in the south-eastern Black Sea, Turkey; (Symphodus ocellatus (Linnaeus, 1758), Symphodus cinereus (Bonnaterre, 1788), Symphodus tinca (Linnaeus, 1758) and Symphodus roissali (Risso, 1810)). A total of 720 fish samples were collected with trammel net between June 2015 and May 2016. The sample sizes, minimum and maximum lengths and weights, length-weight relationships, parameters of a and b, ± 95% CI of b, r², growth type and statistical analyses of the relationship were determined. The b value estimates varied between 2.73 and 3.21. The r² value estimates varied between 0.76 (S. ocellatus) and 0.91 (other species).
