İskenderun Körfezi'nde kullanılan paraketa takımlarında yem çeşidi ve iğne büyüklüğünün tür seçimine etkisi

Araştırma İskenderun Körfezi'nin güney kıyısında bulunan Arsuz (Uluçınar) kıyılarında Eylül 2000-Aralık 2000 tarihleri arasında yürütülmüş ve 30 operasyonda toplam 15.000 iğne ve eşit sayıda 14,10 ve 8 no'lu iğne grupları ile yem olarak subya ve sardalya kullanılmıştır. Çalışma esnasında iğne büyüklüğüne ve yem çeşidine göre değişen miktarlarda 20 familyaya ait 33 balık türü ve 1 tür yumuşakça yakalanmıştır, iğne büyüklüğü faktörü göz önüne alındığında, her 3 iğne numaraları ile avlanılan balık türlerinin av miktarları (adet) arasındaki fark istatistiksel açıdan önemli bulunmuştur. 14 no iğne ile en küçük boy gruplarındaki balıkların yakalandığı, 10 ve 8 no iğneler ile daha büyük boy grubunda balıkların yakalandığı saptanmıştır. Yakalanan toplam 1059 adet balığın 473 tanesi subya yemi ile 586 tanesi sardalya yemi ile yakalanmıştır. Yem faktörünün iğne faktörü ile olan ilişkisi incelendiğinde aralarındaki fark istatistiksel açıdan önemli bulunmuştur.

Effect on the species selectivity of different bait and hook size in longline in Iskenderun Bay, Eastern Mediterranean Sea

Research was carried out on the south of iskenderun Bay near Arsuz (Uluçınar) coast between September and December 2000. Three size of hooks; Number 14,10 and 8 were used for fishing with equal amount of hook and bait. Total thirty fishing operations were done and 15.000 hooks were used in these operations, thirty three fish species which belong to 20 different family and 1 mollusc fish were caught. With regards to size of hook significant differences were found between sizes no 8, 10 and 14. Most of the small fish were caught with No 14 hook; whereas relatively big sizes of fish were caught with hooks no 8 and 10. Total 1059 of fish were captured and of 473 fish were caught using squid as bait and rest of the fish was captured using sardine as bait on the hooks. In term of type of bait (sardine and squid) significant effect were found in no 8,10 and 14 hook. 63% and 70% of fish were almost caught using sardine as bait with no 10 and no 8 hooks respectively.
