Ayvacık Barajı (Çanakkale) Alburnus chalcoides (Güldenstädt, 1772) Populasyonuna Ait Parametrelerin Belirlenmesi

Abstract

respectively. In the light of these values have been estimated there were not any over fishing pressure on the population which is exploited optimally.

Length-Weight Relationship, Condition Factor, and Gonadosomatic Index of Endemic Alburnus istanbulensis (Battalgil, 1941) in Two Different Habitats: Karamenderes River and Bayramiç Reservoir (Çanakkale, Turkey)

“…In reservoir habitats, the length and weight distributions of A. istanbulensis species are more variable. The weight and fork length ranges of specimens were found to be lower in the Bayramiç Reservoir compared to what was described in the literature for the reservoir (Çiçek et al, 2015;Saç & Okgerman, 2016). Except in Darlık Dam, the specimens' fork lengths were lower than in Bayramiç Reservoir (mean: 6.0±2.7 cm; min-max: 1.9-14.5 cm) (Gaygusuz et al, 2017).…”

“…There have been studies on A. istanbulensis species distribution (Sarı et al, 2006;Özuluğ, 2008;Geiger et al, 2014;Saç & Özuluğ, 2014;Boll et al, 2016;Gaygusuz et al, 2017;Saç & Özuluğ, 2017a,b,c;Sarı et al, 2019;Çiçek et al, 2020), maturity and gonadosomatic index (Tarkan et al, 2005;Tarkan et al, 2012;Hamzaoğlu et al, 2015), parasites (Kırcalar & Soylu, 2014), and feeding characteristics (Yalçın Özdilek & Jones, 2014;Yalçın Özdilek et al, 2019). However, there are limited studies on length-weight relationships and length-weight distributions (Tarkan et al, 2005;Tarkan et al, 2006;Saç & Okgerman, 2016;Gaygusuz et al, 2017;, and age distribution (Başdemir et al, 2010;Çiçek et al, 2015) with A. istanbulensis's former name (C. chalcoides and A. chalcoides). Since endemic species are important species in their distribution ranges, it is also important to define their biological characteristic in different habitats.…”
