Marine mammal entanglement, or “by-catch,” is a global problem that results in the death of hundred of thousands of whales, dolphins, porpoises and seals every year. For large whales, the impact is typically not immediate as the animals can pull gear off the ocean floor and swim off with it.

Conservationists, Maas told The Dodo, have been notifying the New Zealand government for years that the dolphin was struggling for its survival. But like many storylines around endangered species, there’s a loop that inevitably takes place. “You go through these cycles where there’s denial of your findings by the detractors,” says Maas. “Then you produce evidence and scientific facts. And if you are lucky, you make incremental progress. And then the cycle starts again: denial, refusal, new evidence and incremental progress.”
Of the 30 cases last year, seven whales were disentangled and released free of lines, seven were found dead, two were observed to self-release and the remaining entangled whales had an unknown fate. Most recent entanglements have occurred with Dungeness crab gear, although lobster and spot prawn gear as well as gillnets have also been identified.

Highly endangered North Atlantic right whales number about 500 individuals. They’re so-named because their slow-moving, shore-hugging habits and tendency to float when dead made them the “right” whale to kill. They were hunted to near extinction by the early 1900s.
