What's at Stake

False killer whales are suffering because of Hawaii’s longline fisheries. Earthjustice is in court to ensure that these majestic creatures are protected from death and serious injury.

Case Overview

In 2004, under pressure from an Earthjustice lawsuit, the National Marine Fisheries Service finally re-classified the Hawaiʻi-based longline fishery as "Category 1"—a designation for fisheries that annually kill and seriously harm marine mammals at unstainable rates—due to its excessive incidental take of Hawaiʻi's false killer whales.

According to the Marine Mammal Protection Act, this recategorization should have triggered the rapid creation of a team that would ensure improvements are made in the fishery to avoid killing or seriously injuring false killer whales. The National Marine Fisheries Service has failed to do so, claiming inadequate funding.

Earthjustice is involved in a long-standing court battle to ensure that appropriate actions are taken to protect this incredible imperiled species.

New regulations will trigger area shutdown after second fatal hooking

In response to the fatal hooking of a false killer whale in February, the National Marine Fisheries Service has warned that a second fatal hooking would trigger the shutdown of more than 100,000 square nautical miles of fishing water south of the Hawaiian Islands for the remainder of 2013. This is a condition of regulations established at the beginning of the year that also require the use of weaker hooks and thicker lines, which are less likely to endanger these animals, which are protected by the federal Marine Mammal Protection Act.

Agency agrees to new long-line fishing rules

The National Marine Fisheries Service has settled a lawsuit filed by environmental groups over accidental bycatch of the false killer whales when Hawaiian fishermen are fishing for tuna and swordfish. The agency has promised to set rules to prevent the deadly effects of long-line fishing on the rare dolphin species being killed at three times the sustainable rate.

Protecting False Killer Whales from Longline Fishing

The federal agency charged with protecting marine mammals settled a court case by pledging to finalize and implement protections for false killer whales by November 30, 2012. False killer whales (Pseudorca crassidens, which are actually large dolphins) have suffered unsustainable levels of death and serious injury in the Hawaiʻi-based longline fisheries.
