Abstract

A juvenile female blue shark, Prionace glauca, 98 cm of total length and weighing 3 kg, was caught on 18 October 2008 off the Altınoluk coast. An adult female, 350 cm of total length and weighing 100 kg, was caught on 16 August 2009 off the Ayvacık coast. Available data suggest the following facts: (1) the rarity of the blue shark in the studied area; (2) P. glauca enters fishery in the studied area in the first year of life; and (3) coastal trammel- and gill-netting is a serious threat to the survival of the young populations of the species in Edremit Bay.
