Abstract:
In this study, comparison of the missed fish, hooking efficiency, injury rates and
mortality potential of circle hooks and common octopus hooks for Smith Delagoa
Treadfish Bream has been conducted. The Smith Delagoa Treadfish Bream was
captured along Terengganu coastal water. The terminal set up for both hook were
standardized for all the angler. Upon detecting a strike, angler's fishing with octopus
hooks was instructed to set the hook whereas those fishing with circle hook were told
to reel in any slack and to apply constant pressure to the line. While capture, the
anatomical location of the hook were recorded. Ease of hook removal was
categorized using the slight modifications. After assessing ease of hook removal, the
recorder looked for the presence of blood and recorded responses as either none,
little or serious. In the present study, 25.67% fish captured on circle hooks were less
bleeding and were more easily to remove from the hook than those were captured on
octopus hooks with 48.94 %. Majority of fish landed with circle hook were hooked
at side jaw with 42.66% while 45.82% fish landed by octopus hooks were hooked at
gullet. Results showed that mortality potential rate of circle hook were lower than
octopus hook with 18.81% for circle and 43.66% for octopus.
