Killer whale ( Orcinus orca ) interactions with blue-eye trevalla ( Hyperoglyphe antarctica ) longline fisheries

International audience Over the past five decades, marine mammal interactions with fisheries have becomea major human-wildlife conflict globally. The emergence of longline fishing is concomitantwith the development of depredation-type interactions i.e., marine mammalsfeeding on fish caught on hooks....

The emergence of longline fishing is concomitantwith the development of depredation-type interactions i.e., marine mammalsfeeding on fish caught on hooks. The killer whale (Orcinus orca) is one of the speciesmost involved in depredation on longline fisheries.

The present study investigated killer whaleinteractions with two geographically isolated blue-eye trevalla (Hyperoglyphe antarctica)fisheries operating in temperate waters off Amsterdam/St. Paul Islands (Indian Ocean)and south-eastern Australia. These two fisheries differ in the fishing technique used(vertical vs. demersal longlines), effort, catch, fleet size and fishing area size.

In south-eastern Australia,the probability of occurrence of killer whale interactions during fishing days variedseasonally with a decrease in spring, increased with the daily fishing effort and decreasedwith the distance travelled by the vessel between fishing days.
