MURAT NEHRI (PALU-ELAZIĞ)’NDE YAŞAYAN CAPOETA TRUTTA (HECKEL, 1843) TÜRÜNÜN BAZI MERISTIK VE MORFOMETRIK ÖZELLIKLERI

Abstract

In the present study, some meristic and morphometric characteristics of 66 Capoeta trutta (Heckel, 1843) fish samples collected from Murat River (Palu-Elazığ) were examined. The samples were immediately preserved with ice and fixed with 5% formaldehid on arrival in the laboratory. Metric measurements were carried out with 0.01 mm sensitive calipers. Meristic characters were counted as number of the dorsal fin rays, number of the anal fin rays, number of the pelvic fin rays, number of the pectoral fin rays, number of scales on the lateral line and number of the pharyngeal teeth. The morphometric characters were measured as total length, fork length, standard length, predorsal length, postdorsal length, caudal peduncle length, body width, body height, snout length, head length, head width, eye diameter, mouth width, intertorbital length, distance between pelvic fin and anal fin, distance between pelvic fin and pectoral fin. Morphometric measurements as total length percentage and total length regression models and determination coefficients (r2) were calculated. Generally, a significant, high, positive correlation was found between total length and morphometric measurements (r2= 0.70-0.92, p<0.01).
