摘要

The pike is one of the most valuable freshwater fish species in Turkey. This study was carried out in order to estimate the selectivity properties of gillnet used in pike (Esox lucius L., 1758) fishing in ?ivril Lake, Turkey. The study was performed between January 2005 and December 2005 and selectivity estimates were based on six different monofilament gillnet mesh sizes (i.e. 4, 5, 6, 7, 8 and 9 cm). The SELECT method was used to estimated the selectivity parameters. According to the bi-normal model, optimum model lengths for 4, 5, 6, 7, 8 and 9 cm mesh sizes were determined as 20.99, 26.24, 31.49, 36.73, 41.98 and 47.23 cm respectively. When considering minimum landing size, the findings of the study showed that the use of gillnets of mesh size less than 8 cm should be prohibited for the fishing of E. lucius in ?ivril Lake.
