The maximum mean length of K. pelamis (65±2 cm) was measured in summer (2010-2011) and minimum mean
length (55±2 cm) was recorded in autumn (2008-2009). The maximum mean weight (3200±309 g) was obtained
in summer (2010-2011) and minimum mean weight (1750±259 g) was recorded in autumn (2007-2008) (Table 1).
