gillnet selectivity of saddled seabream </span> <i> <span style="font-size:12px;"> </span> </i> <span style="font-size:12px;">( </span> <i> <span style="font-size:12px;">Oblada melanura </span> </i> <span style="font-size:12px;">), common

mm mesh size (nominal bar lenght) have been determined. Fishing trials were
carried out in Noth Aegean Sea from March 2008 to February 2010. Selectivity
parameters were estimated using the Select method. Most suitable selectivity
models were calculated as log-normal for saddled seabream </span> <i> <span style="font-size:12px;"> </span> </i> <span style="font-size:12px;">( </span> <i> <span style="font-size:12px;">O.

Optimum catch
lengths for 20, 22, 23 and 25 mm mesh size were 11.15, 12.27, 12.83 ve 13.94 cm

15.3, 16.83, 17.59 and 19.12 cm for saddled seabream </span> <i> <span style="font-size:12px;"> </span> </i> <span style="font-size:12px;">( </span> <i> <span style="font-size:12px;">O. melanura </span> </i> <span style="font-size:12px;">)
and 26.68, 29.35, 30.68 and 33.35 cm </span> <i> <span style="font-size:12px;"> </span> </i> <span style="font-size:12px;">for Mediterranean horse
mackerel </span> <span style="font-size:12px;">( </span> <i> <span style="font-size:12px;">T. mediterraneus </span> </i> <span style="font-size:12px;">) </span> <i> <span style="font-size:12px;">, </span> </i> <span style="font-size:12px;">respectively.
These findings may help us to understand that using higher than 23 mm stretched
mesh size with gillnets which have been used for commercial bogue fisheries
around north Aegean Sea is important for sustainability of fisheries. </span> </span> </p> <p> </p> </div>}, number={1}
