Also available in:
No results found.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 on the Indonesian tu longline fishery in the Indian Ocean. The study was conducted during 2010 – 2011 following six commercial tu longline vessels based in Port of Benoa. The results showed that discards comp osition reach almost 20% from total catch. Those discards composition was domited by longnose lancetfish (32.73%) and pelagic stingrays (11.62%) which both species contribute almost half of total discards. Later followed by crocodile shark (6.07%), ske mackerel (0.41%), ocean sunfish (0.14%), olive ridley turtle (0.07%), with hammerhead shark, tappertail ribbonfish, false killer whale and leatherback sea turtle 0.02% each. Almost half of total catch are discards and half of discards are disposed dead or dying. These findings indicate the need for special magement to reduce the discards for tu longline in Indonesia. -
