Abstract

In this study it was investigated that the selectivity of monofilament and multifilament gillnets with mesh sizes from 36 to 40 mm for fishing horse mackerel (Trachurus trachurus, L., 1758) between October 2001 and February 2002 inside harbour of Sinop. Selectivity parameters were estimated using the indirect method proposed by Holt (1963) method. A total of 3520 specimens were collected by experimental nets. 53.86% and 46.14% of them were caught by monofilament and multifilament gillnets, respectively. The common selection factor was found as 4.90 for monofilament and 4.84 for multifilament gillnets.

Özet

Bu çalışma, monofilament ve multifilament materyalden yapılmış 36 ve 40 mm ağ göz genişliğine sahip galsama ağlarının istavrit balığı (Trachurus trachurus, L., 1758) için seçiciliğini belirlemek amacıyla Ekim 2001 ve Şubat 2002 tarihleri arasında Sinop iç liman bölgesinde yürütülmüştür. Ağların seçiciliğinde dolaylı hesaplama yöntemi olan Holt (1963) metodu kullanılmıştır. Deneme ağlarıyla toplam 3520 adet balık yakalanmıştır. Balıkların %53.86’si monofilament ağlarla, %46.14’ü multifilament galsama ağlarıyla yakalanmıştır. Genel seçicilik faktörleri monofilament ağlar için 4.90, multifilament ağlar için 4.84 olarak bulunmuştur.
