DISCARDS OF THE INDONESIAN TUNA LONGLINE FISHERY IN INDIAN OCEAN
Abstract: Incidental by-catch
and associated discarding are difficult to estimate on the basis of logbook
information because they are poorly reported by fishing masters and their
importance varies with several interrelated factors. The purpose of this paper
is to inform the commonly discarded fishes of the Indonesian tuna longline
fishery in the Indian Ocean. The study was carried out during 2010 – 2011
following six commercial tuna longline vessels based in Port of Benoa. Discards
composition was dominated by longnose lancetfish and pelagic stingrays which
composed almost half of total discards. Almost half of total catch are discards
and half of discards are disposed dead or dying.
