Özet
Bilimsel ve ticari olarak trollerin sualtı geometri ve performans değerlerine ihtiyaç duyulmaktadır. Performans verilerini toplamak için, sualtı dalış araçları (kızaklar) ve teknikleri, kendi üzerine veya merkezi ünitede kayıt yapabilen elektro-mekanik ve elektro-akustik cihazlar, echo-sounderler, sonarlar ile kablolu ve kablosuz net-sonda sensör (sinyal vericiler) sistemleri geliştirilmiştir. Makalede, cihaz ve yöntemlerin kayıt şekli sınıflandırmada esas alınmıştır. Son yıllarda, sensörlerden akustik telemetri ile gönderilen bilgilerin, bilgisayar destekli ekranlara veya görüntü kabinlerine ulaştırılması en çok tercih edilen yöntemdir. Net-spnda olarak adlandırılan bu sistemle, trolün farklı yerlerine yerleştirilen sensörler saybsinde, amaca uygun değişik bilgiler toplanmaktadır. Bu cihazlar ile geleneksel dip trol ağlarının performans sonuçlan ortaya çıkarılıp, ağların kusurları ve yetersizlikleri giderilmeye çalışılmalıdır. Dip trollerinin, her koşulda geometri-performans verileri incelenerek en uygun trol çekim protokolü oluşturulmalıdır. Bütün bu çalışmaların sonucunda, yüksek performans sergileyen standart ağ ve çekim yöntemi belirlenmelidir.
Geometry-performance measuring at trawling gear. There is a need for under-water geometry and performance values of trawl both for scientific and commercial reasons. To obtain performance values, under-water towed vehicles (sledges), diving technique, electro-mechanic and electro-acoustic instruments that can self record or log the data on a central unit, echo-sounders, sonars and, cabled or cable free net sonde sensor systems have been developed. Classification in this study has based on type of recording of the instruments and methods. Transfer of the information from sensors via acoustic telemetry to software-supplied monitors and cabinets is the most preferred method of recent years. This system, known as net-sonda, is able to collect various information according to the purpose via sensors mounted in different parts of the trawl. With the help of these systems, performance values of conventional trawls should be investigated, and gear faults and defects need to be solved. Geometry-performance values of bottom trawl gears need to be investigated in all possible towing conditions and the most convenient towing protocol should be established. As a result of these studies, standard gear and towing method which show a high performance should be determined.
