Abstract



The present study
compares size selectivity of commercially used hand-woven slack knotted codend
and three different alternative (40 mm square mesh, 44 mm and 50 mm diamond
mesh) machine woven codends for bogue (Boops boops) and common sole (Solea
solea). Hauls were conducted using covered codend method between 10 October and
16 December 2011 in Mersin Bay. Results show that alternative machine woven
codends are selective enough for bogue however, tested four codends are not
sufficient in releasing individuals under legal size for common sole.

Abstract



Bu çalışmada
ticari el örmesi ve gevşek düğümlü torba ile üç farklı alternatif fabrikasyon
torbaların (40 mm karegöz, 44 mm ve 50 mm baklava gözlü) boy seçicilikleri
kupes (Boops boops) ve dil balığı (Solea solea) için karşılaştırılmıştır.
Çekimler Mersin Körfezi’nde 10 Ocak - 16 Aralık 2011 tarihleri arasında örtü
torba yöntemi kullanılarak gerçekleştirilmiştir. Sonuçlar alternatif
fabrikasyon torbaların kupes için yeterli seçiciliğe sahip olduğunu bununla
beraber dil balığı için test edilen 4 torbanın da yasal boyun altındaki
bireyleri kaçırmada yetersiz kaldığını göstermektedir.
