Gillnet and trammel net selectivity for Prussian carp (Carassius gibelio) in Marmara Lake, (Turkey)

Abstract

This study aimed to determine the selectivity properties of multifilament gillnets and trammel nets for Prussian carp (Carassius gibelio 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 Carassius gibelio 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 C. gibelio. In addition, C. gibelio was the second species by production rate in Turkey inland fisheries; therefore, it should be economically evaluated using different processing techniques.
