These nets used in coastal waters less than m deep have entangled and killed thousands of dolphins and have caused catastrophic damage. Their future is in the hands of the New Zealand government. If it acts, as it has been urged to do by scientists locally and globally, and 1 bans gillnets and trawl nets in New Zealand waters less than m deep, and 2 encourages the use of alternative fishing methods that do not kill dolphins such as fish traps and hook and line fishing , the decline in dolphin numbers will stop and populations will have the chance to recover.
By adopting a whale or dolphin, by making a donation, or by fundraising for WDC, you can help us provide a safe future for the New Zealand dolphin.
Cephalorhynchus hectori. See all species. Male Female Calf Maximum length 1. Distribution map. We need the New Zealand government to prohibit the use of destructive fishing methods in the dolphins' home before they are wiped out forever. Join the campaign. Just 10, As many as The Dolphin Protection Consumer Information Act established a national tuna tracking program to ensure that tuna imported into the United States meets certain requirements to ensure the safety of dolphins during tuna fishing operations.
Under the Marine Mammal Protection Act , an unusual mortality event UME is defined as "a stranding that is unexpected; involves a significant die-off of any marine mammal population; and demands immediate response.

They face both bycatch and collision risks from smaller boats. They also live in shallow areas, above m feet. Some groups reside in small areas of about 30km If we use the same ratio for an adult male human of around 90kg lb , the average weight in the USA, his testes would weigh 2. Indeed, these small dolphins face many threats.
The biggest threat to their survival is by far fishing with bycatch and entanglements. Researchers even affirmed that entanglements caused a loss of genetic diversity in this species of dolphin. They also created several sanctuaries around the South Island to help the populations recover.
