Abstract

This study aimed to determine the spatial and temporal variation of species diversity and CPUE in trawl fisheries in the Central Aegean Sea (Sığacık Bay). The study also aimed to evaluate changes in some biometric parameters (mean and frequency of length) depending on the season and depth for three important commercial species (Parapenaeus longirostris, Nephrops norvegicus and Illex coindetii). Monthly trawl samplings were carried out in three depth strata (0-200; 201-400 and 401-600 m) between May 2008 - April 2009. A total of 111 species were identified including 74 Osteichthyes, 13 Chondrichthyes, 18 Cephalopods and 6 Crustaceans. The highest species diversity and catch per unit effort (CPUE) values were obtained at 201-400 m strata. Among these, Osteichthyes had the highest frequency and CPUE values in all strata and seasons. Summer was the season with the highest CPUE in all groups followed by a decrease until winter due to openning of trawl fisheries in the Autumn. The mean carapace length of P. longirostris, the target species in Sığacık Bay trawl fisheries, increased with depth and this species was more abundant at the 201-400 m strata.

Sığacık Körfezi'ndeki (Orta Ege Denizi, Türkiye) Demersal Topluluklarının Mekansal ve Zamansal Özellikleri

Abstract

Bu çalışma, Orta Ege Denizi'nde (Sığacık Körfezi) trol balıkçılığında tür çeşitliliği ve CPUE'nin mekansal ve zamansal değişimini belirlemeyi amaçlamıştır. Çalışmada ayrıca üç önemli ticari tür (Parapenaeus longirostris, Nephrops norvegicus ve Illex coindetii) için mevsime ve derinliğe bağlı olarak bazı biyometrik parametrelerin (ortalama boy ve boy frekansı) değişiminin değerlendirilmesi de amaçlanmıştır. Aylık trol örneklemeleri Mayıs 2008 ile Nisan 2009 tarihleri arasında 3 derinlik katmanında (0-200; 201-400 ve 401-600 m) gerçekleştirilmiştir. 74’ü Osteichthyes, 13’ü Chondrichthyes, 18’i Cephalopoda ve 6’sı Crustacea grubunda olmak üzere toplam 111 tür tespit edilmiştir. En yüksek tür çeşitliliği ve birim çaba başına av miktarı (CPUE) değerleri 201-400 m derinlik katmanında elde edilmiştir. Gruplar arasında, tüm katmanlarda ve mevsimlerde en yüksek frekans ve CPUE değerlerine Osteichthyes grubu sahiptir. Yaz mevsimi, tüm gruplarda CPUE'nin en yüksek olduğu mevsimdir ve sonrasında sonbaharda başlayan balıkçılığın etkisiyle değerler kışa kadar düşmüştür. Sığacık Körfezi trol balıkçılığında hedef tür olan P. longirostris'in ortalama karapaks boyu derinlikle birlikte artmış ve bu tür 201-400 m derinlik katmanında daha bol bulunmuştur.
