Seasonal discards and by-catch of striped venus clam (Chamelea gallina) (Mollusca, Bivalves) fishery in the black sea

Öz:
Karadenizin Türkiye kıyılarında beyaz kum midyesi, Chamelea gallina, avcılığı yapan hidrolik direç donanımlı teknelerin mevsimsel ıskarta ve hedef dışı av miktarları tespit edilmiştir. Bu çalışmada kullanılan veriler araştırmacılar tarafından Eylül 2009 ve Nisan 2010 tarihleri arasında ticari av teknelerinden elde edilmiştir. Elde edilen sonuçlara göre Karadenizde hidrolik direçlerin ürettikleri ıskarta miktarları karaya çıkarılan ürünün %36sına tekabül etmektedir ve bunun yaklaşık %19u asgari av boyunun (<17 mm) altındaki kum midyesi bireylerinden oluşmaktadır. Çalışma süresince toplam 38 tür tespit edilmiştir ve keşiş yengeci (Diogenes pugilator) ile deniz salyangozu Rapana venosa tüm istasyonlarda her mevsim elde edilen iki ana ıskarta türdür. Kışın ve ilkbaharda yapılan çekimler, tür çeşitliliği ve homojenlik değerleri açısından sonbaharda yapılanlara göre önemli derecede farklıdır.

Karadeniz de beyaz kum midyesi (Chamelea gallina) avcılığında mevsimsel ıskarta ve hedef dışı av

Öz:
Seasonal discards and by-catch of hydraulic dredges targeting striped venus clams, Chamelea gallina, from the Black Sea coasts of Turkey were determined. Data presented in this study were collected by researchers aboard between September 2009 and April 2010. Results indicated that discards were 36% of the landed product, of which 19% was composed of undersized (<17 mm) clams. During the study, a total of 38 species were identified and the hermit crab (Diogenes pugilator) and the gastropod Rapana venosa were the two main species captured as discard from all sampling stations in every season. Species diversity and evenness index values, of winter and spring hauls were significantly different from autumn ones.
