Geleneksel dip trol ağından kaçan tavuk balıklarının (Trisopterus minutus capelanus Lacepede, 1800) yaşama oranı

Bu çalışmada geleneksel dip trol ağından kaçan tavuk balığı (Trisopterus minutus capellenus Lacepède, 1800) için yaşama oranı tespitine çalışılmıştır. Denemelerde, geleneksel dip trol torbasından kaçan balıklar örtü torba yöntemiyle tekrar yakalanmış ve 7-8 m derinlikteki 5.4 m3 hacmindeki kafeslere yerleştirilerek balıkadamlar tarafından gözlenmiştir. Kafeslerde balık ölümlerinin devam etmemesi üzerine çalışmanın başlamasından 6 gün sonra kafes içerisindeki balıklar alınarak çalışma bitirilmiştir. Çalışma sonunda tavuk balığı için yaşama oranı %57olarak tespit edilmiştir

Survival rate of poor cod (Trisopterus minutus capelanus Lacepede, 1800) escaping from traditional bottom trawl

Survival rate of poor cod (Trisopterus minutus capelanus Lacepède, 1800) escaping from traditional bottom trawl. The survival rate of poor-cod (Trisopterus minutus capelanus Lacepède, 1800) escaping from traditional bottom trawl cod-end was examined. In this trial, escaping fish from traditional bottom trawl cod-end were recaptured with hooped cover cod-end method and retained in 5.4m3 cages at 7-8 meters depth. The cages were obtained by divers during the experiment. After six days commencement of experiment, the trial was terminated and fish were taken from cages hence, fish death was not occurring any more. As a result of this experiment survival rate of poor-cod, was determined %57.
