Hawaiian Islands False Killer Whale

Acoustically monitoring the Hawaiʻi-primarily based longline fishery for interactions with false killer whales. Establishing a take discount group and publishing a take reduction plan to cut back bycatch of Hawaiian false killer whales in industrial longline fisheries. The small size of the endangered major Hawaiian Islands insular false killer whale inhabitants poses a novel threat to this group.

The historical population dimension is unknown, although spotter planes within the late 1980s observed large aggregations of 350 to four hundred whales in a single space. Aerial survey sightings since then counsel that the principle Hawaiian Islands insular false killer whale inhabitants declined at a mean price of 9 % per yr through at least the early 2000s. The false killer whale has been identified to method and supply fish it has caught to people diving or boating. However, it additionally takes fish off of hooks, which typically results in entanglement or swallowing the hook.

Playful and active, false killer whales are quick swimmers and might frequently be seen surfing the bow waves of vessels or poking out of the water.

Information You Did Not Find Out About False Killer Whales

MHI insular false killer whales are also weak to fishery interactions. Few deaths or critical accidents resulting from fisheries interactions have been documented in this population, but correct estimates of the variety of fisheries interactions are not obtainable as a result of the inshore fisheries are not monitored. To reduce bycatch in the longline fishery of people from the MHI insular false killer whale inhabitants, the TRP beneficial, and in 2012 NMFS implemented, a 12 months-spherical closure of longline fishing within about 50 nautical miles of the MHI. The false killer whale is a big member of the dolphin household found in tropical, subtropical and warm temperate waters worldwide.
