Abstract
The aim of this study which was carried out on different bottoms is to reveal that 4 different
sizes (2, 4, 6, 8 no) of straight and kirbed hooks on 4 tippets used on the Suez puffer Lagocephalus
suezensis to determine elimination by using the most used hooks in handline fishing between
September 2015 and March 2016 in Gökova Bay in the Aegean Sea. Throughout the fieldworks,
44 individuals of Suez Puffer have been caught. Total weights were ranged from 10.99 g to 86.29
g. 10.68 % (1525.55 g) of obtained total catch (14658.53 g) was captured with straight and kirbed
hooks. Total lengths were ranged from 8.2 cm to 16.2 cm and SL-W relation was significant
(R2
:0.97). The relationship between mouth size and SL was insignificant (R2
:0.40). Except two of
individuals which have been caught from eye and dorsal side, there was no vital wounds observed
on fish samples. The reactions to the bait after fishing lines casted in 4.42 min. (sd. 4.98 min.) and
over 50% of captured individuals were fished in less than 3 minutes. There was no statistical
difference found between two type of hooks (P<2.34). During the study, 60% of 44 fishes obtained
were caught with straight hooks and 40% with kirbed hooks. Consequently, as seen in the
percentages, given that 10.6% of the population in industrialized countries is interested in
recreational fishing, encouragement people to recreational fishing, thus, to fish pufferfishes by
specific recreational fishing methods is one of alternative ways to control of pufferfish population
in our waters.
