Yılmaz S., Polat N. 2009. Length–weight relations of Anatolian khramulya, Capoeta tinca (Actinopterygii: Cypriniformes: Cyprinidae), from Samsun Province, northern Turkey. Acta Ichthyol. Piscat. 39 (1): 39–41. Abstract. The parameters of length–weight relations for Anatolian khramulya, Capoeta tinca (Heckel, 1843) from 10 inland bodies of water of the Samsun Province, Northern Turkey were presented. The b values of the length–weight relations ranged from 2.5444 to 3.3517. For nine freshwater resources in Samsun, this study is the first reference on length–weight relation of Capoeta tinca . Keywords: fish, length–weight relation, Anatolian khramulya, Capoeta tinca , Samsun province, Turkey

Length–weight relations are useful in determining Capoeta tinca captured from 10 freshwater sites of the weight and biomass when only length measurements are above-mentioned province. available, and allow comparisons of species growth Capoeta tinca specimens were collected from 10 fresh - between different habitats and/or regions (Koutrakis and water sites in the Samsun Province. Three of these bodies Tsikliras 2003, Oscoz et al. 2005). of water (Çakmak and Derbent dam lakes, and Divanbaşı Anatolian khramulya, Capoeta tinca (Heckel, 1843) Pond) are lentic habitats while seven others (Gamlık, is a species of the family Cyprinidae and has a wide dis - Istavloz, Küplüağzı, Tersakan, Yakakent, Mertırmagı tribution in western Asia (Yıldırım and Aras 2000).

Fish were caught original distribution areas in Turkey are the rivers and with nets and electrofishing device in different periods, streams of the northern- and northwest Black Sea regions from July 2003 to February 2005.

Capoeta tinca can adapt very were measured to the nearest 0.1 cm fork length (FL) and easily to changes in aquatic environment, and occurs weighted to the nearest 0.1 g total weight ( W). both in lotic and lentic habitats. Furthermore, the species Length–weight relations were calculated using the has economic value as a commercial fish in natural and equation W = aL b, where W is the total weight of the fish man-made lakes. It is a herbivorous fish, but its nutrition [g], L is the fork length [cm], a and b are the parameters value is lower than that of other species like Esox lucius , of the equation (Bagenal and Tesch 1978). The parame - Sander lucioperca , or Silurus glanis . Despite that, it is ters a and b were estimated by linear regression of the consumed by people owing to its wide distribution, its transformed equation: log W = log a + b log FL. The tolerance to different habitats and its size (Ekmekçi and determination coefficient ( r2) was used as an indicator of Özeren 2003). the quality of the linear regression. In Turkey, length–weight relations of Capoeta tinca Length and weight descriptive statistics (number of were investigated in the Kızılırmak (Akgül 1987, Yılmaz specimens ( n), minimum and maximum fork lengths, and Gül 1999, Gül and Yılmaz 2002) and Sakarya mean fork length, standard deviation of the mean fork (Yılmaz et al. 1996) river basins, and Almus Dam Lake length, minimum and maximum total weights, mean total (Cengizler and Erdem 1994). No study has previously weight, standard deviation of the mean total weight) as been carried out, however, on length–weight relations of well as the parameters of the length–weight relation ( a, b, Capoeta tinca inhabiting many inland bodies of water in 95% confidence intervals of b, r2) of Capoeta tinca for the Samsun Province, northern Turkey. The aim of this each freshwater resource are given in Table 1. Sample study was to determine the length–weight relations of size ranged from 7 for Gamlık and Tersakan streams,
