to determine the selectivity properties of multifilament gillnets and trammel
nets for Prussian carp ( <i>Carassius gibelio </i>
Bloch,1782) in Marmara Lake (Manisa, Turkey). A total of 36 fishing trials were
performed with three different stations on a monthly in 2012. Nets with same
mesh sizes (4, 6, 8 and 10 cm) and characters were used in gillnets and trammel
nets. SELECT method was utilized to estimate the selectivity parameters. Normal
scale and normal location model gave the best fit for gillnet and trammel nets
respectively. A total of 2234 <i>Carassius
gibelio </i> were caught ranges between 8.80-27.50 cm in total lengths. The
model length for 4 cm mesh size was estimated as 12.71 cm for gillnets and
12.04 cm for trammel nets. No statistical differences were found between
estimated model lengths for different sex groups. Model lengths are much higher
than first maturity size which 11.5 cm was given by different authors. This
situation makes it impossible combating with this invasive species. Therefore,
special fishing equipment or devices are needs to be investigated just for
caught <i>C. gibelio. </i>In addition, <i>C. gibelio </i> was the second species by
production rate in Turkey inland fisheries; therefore, it should be economically
evaluated using different processing techniques. </span> </p> <p> </p> </div>}, number={1}, publisher={Ege Üniversitesi}
