Body-Shell Dimension Relations and Growth Parameters of the Invasive Ark Clam (Anadara inaequavalvis) in Turkish Coast of the Black Sea

Abstract

In this paper, the relationship between bodyshell dimensions and growth parameters of ark clam (Anadara inaequavalvis Bruguière, 1789) were estimated for the Black Sea. At the end of this research, there was a significant relationship between body size and shell dimensions. In addition to this, the Von Bertalanffy growth parameters were found as L_∞=8.61 mm, K= 0.25 and t₀= -0.43 yr^-1. Mortality rates were also analyzed for the ark clam as Z= 0.95 yr^-1, M= 0.77 yr^-1, F= 0.18 yr^-1. This research is important in terms of the first study of bodyshell dimension relationships and mortality rates for Anadara inaequavalvis from the Black Sea. The ark clam can use a descriptor for the Good Environmental Status (GES) according to Marine Strategy Framework Directive (MSFD) 2^th Task Group in European Commission.

İşgalci Anadara inaequivalvis’in Vücut-Kabuk Boyutları İlişkileri ve Büyüme Parametreleri

Abstract

Bu çalışmada Karadeniz’de Anadara inaequavalvis (Bruguière, 1789)’in vücut-kabuk boyu ilişkileri ve büyüme parametreleri tahmin edilmiştir. Sonuç olarak, vücut ölçüleri ile kabuk boyutları arasında önemli bir ilişki gözlenmiştir. Buna ek olarak, Von Bertalanffy büyüme parametreleri L_∞=8.61 mm, K= 0.25 and t₀= -0.43 yr^-1 olarak bulunmuştur. Ayrıca, ölüm oranları Z= 0.95 yr^-1, M= 0.77 yr^-1, F= 0.18 yr^-1 olarak hesaplanmıştır. Bu çalışma, Anadara inaequavalvis’in vücut-kabuk boyutları arasındaki ilişki ve ölüm oranlarının tahmin edildiği ilk çalışma olma özelliği taşımaktadır. Bu tür Avrupa Komisyonu’nun Deniz Stratejisi Çerçeve Direktifi 2. Grup’ta İyi Çevre Statüsü’nün bir tanımlayıcısı olarak da kullanılmaktadır.
