The length-weight relationships of two flatfish species (Solea solea Linnaeus, 1758 and Pegusa lascaris Risso, 1810) caught in the Middle Black Sea coasts

Abstract

The study was performed between September 2015 and August 2016 with trammels nets having a different mesh sizes (32 mm, 36 mm and 40 mm), which are extensively used in Middle Black Sea coastal fisheries. Common sole (Solea solea L., 1758 and Pegusa lascaris R., 1840) are caught as by-catch in the area with trammel nets. The average length of the species caught in the study were 18.8±2.04 cm for S. solea and 14.8±1.55 cm for P. lascaris. The average weight of the S. solea and P. lascarais were 38.7±24,4 g and 29.7±12.39 g, respectively. The length-weight relationship of S. solea and P. lascarais caught with trammel nets on the shore of Middle Black Sea were calculated as W=0,0028L3,4226 (R2=0,9228, N=528) and W= 0,0049L3,2117 (R2= 0,913, N=558), respectively. The findings, which were presented for the first time for sole fish species in the Middle Black Sea, are expected to be a source for future studies.

Orta Karadeniz (Sinop) kıyılarında avlanan iki dil balığı türünün (Solea solea Linnaeus, 1758 ve Pegusa lascaris Risso, 1810) boy-ağırlık ilişkilerinin belirlenmesi

Öz

Bu çalışma, Orta Karadeniz kıyı balıkçılığında yoğun olarak kullanılan farklı ağ göz açıklığına sahip (32 mm, 36 mm ve 40 mm) fanyalı uzatma ağları ile Eylül 2015-Ağustos 2016 tarihleri arasında gerçekleştirilmiştir. Bölgede uzatma ağları ile yapılan avcılıkta dil balıkları (Solea solea L., 1758 ve Pegusa lascaris R., 1840) hedef dışı tür olarak avlanmaktadır. Araştırmada avlanan türlerin ortalama boyları sırasıyla 18,8±2,04 cm ve 14,8±1,55 cm, olarak saptanmıştır. Türlerin ortalama ağırlıkları ise S. solea için 38,7±24,4 g, P. lascaris için 29,7±12,39 g olarak belirlenmiştir. Orta Karadeniz kıyılarında uzatma ağları ile avlanan S. solea ve P. lascaris dil balığı türlerinin boy-ağırlık ilişkileri sırasıyla W=0,0028L3,4226 (R2=0,9228, N=528) ve W= 0,0049L3,2117 (R2=0,913, N=558) şeklinde hesaplanmıştır. Bu çalışma dil balığı türleri için Orta Karadeniz’deki ilk veri niteliği oluştururken, yapılacak diğer çalışmalara kaynak oluşturması hedeflenmiştir.
