Abstract: In this study, length-weight relationship for 10 fish species (Cyprinus carpio (common and mirror carp), Anatolichthys iconii, Atherina boyeri, Carassius gibelio, Pseudophoxinus egridiri, Pseudorasbora parva, Sander lucioperca, Seminemacheilus ispartensis and Vimba vimba) in Lake Eğirdir were assessed. Samples were obtained monthly from January 2010 to June 2011 of Lake Eğirdir, in Turkey. Moreover, for 3 Anatolian endemics species ( A. iconii, S. ispartensis and P. egridiri) determined for the first time new maximum lengths are recorded. Keywords: Endangered fish, fishbase, growth type, lake Eğirdir, red list, Turkey. Eğirdir Gölü’nden 10 Balık Türünün Boy-Ağırlık İlişkisi Öz: Bu çalışmada; Eğirdir Gölü’nde 10 balık türünde (Cyprinus carpio (pullu ve aynalı sazan), Anatolichthys iconii, Atherina boyeri, Carassius gibelio, Pseudophoxinus egridiri, Pseudorasbora parva, Sander lucioperca, Seminemacheilus ispartensis ve Vimba vimba) boy- ağırlık ilişkisi değerlendirilmiştir. Türkiye'de Eğirdir Gölü'nden Ocak 2010'dan Haziran 2011'e kadar aylık olarak numuneler alınmıştır. Ayrıca ilk kez belirlenen 3 Anadolu endemik türü ( A. iconii, S. ispartensis ve P. egridiri) için yeni maksimum uzunluklar kaydedilmiştir. Anahtar kelimeler: Büyüme tipi, Eğirdir gölü, fishbase, kırmızı liste, nesli tükenmekte olan balık, Türkiye. INTRODUCTION Eğirdir Lake, which is a tectonic lake, is located at about 924 m from sea level with a total surface area of 500 km 2 and the second largest freshwater in Turkey (Lahn, 1948; Numann, 1958). Information of length-weight relationships are principal in fisheries sustainability and population dynamics (Tarkan & Vilizzi, 2016). In addition, length-weight relationship with the expressed fish growth is isometric or allometric (Le Cren, 1951; Ricker, 1975; Pe´rez-Bote & Roso, 2012). Length-weight relationship parameters (a and b), gives the possibility to estimate the size of fish by weight, the calculation of the index condition, in different habitats populations of morphology and to compare their life cycle (Britton & Davies, 2007; Yılmaz et al., 2007; Yılmaz et al., 2010; Pe´rez-Bote & Roso, 2012; Giosa et al., 2014; Alagoz Erguden, 2015; Yoğurtçuoğlu & Ekmekçi, 2015; * : https://orcid.org/0000-0002-2108-1853 : https://orcid.org/0000-0002-0416-3670 : https://orcid.org/0000-0002-7897-1734 : https://orcid.org/0000-0002-7342-9380 : https://orcid.org/0000-0002-2307-3611 : https://orcid.org/0000-0002-7482-6353 : https://orcid.org/0000-0001-5349-1497 *Sorumlu yazar: Meral APAYDIN YAĞCI Koyunculuk Araştırma Enstitüsü Müdürlüğü, T.C.
