Determination of Selectivity Monoflament and Multiflament Gillnets with Different Mesh Size for Horse Mackerel (Trachurus trachurus L., 1758)
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.
