Biological and genetic structure of Epinephelus costae (Steindachner, 1878) population in Iskenderun Bay, eastern Mediterranean Sea
Servet Ahmet Doğdu
TL;DR
This study examines the genetic and biological health of Epinephelus costae in Iskenderun Bay, finding the population to be stable.
Contribution
The study provides new biological and genetic data on E. costae in the eastern Mediterranean, including growth parameters and haplotype diversity.
Findings
The population has high haplotype diversity (0.9379) and low genetic diversity (0.0332 ± 0.0028).
Age 2 individuals dominate the population (31.69%).
The population is found to be in stable condition based on genetic and biological analyses.
Abstract
This study aimed to status of the Iskenderun population of Epinephelus costae, an important fish species in the Mediterranean Sea ecosystem, by providing detailed data on its genetic structure using mtDNA COI gene region and biological parameters as length-weight relationship, age-growth characteristics, von Bertalanffy growth parameters. A total of 325 specimens were studied from Iskenderun Bay in the eastern Mediterranean (Türkiye), ranging in length from 16.7 to 43.5 cm. For genetic studies using the mtDNA COI gene region, 30 samples were selected from different size groups representing the population. Age 2 represented the majority of the population (31.69%). The value of “b” of the length-weight relationship was higher than “3” (3.0839). The results for the von Bertalanffy growth parameters were observed as Lα = 125.8 cm; k = 0.0570 year −1; t0 = − 2.2410 year. Fulton’s condition…
