Their small size and the fact that they live in coastal environments is one of the reasons why they are endangered. 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.
Other things you can do Report any set nets or trawlers operating within an area closed to these types of fishing by phoning the Ministry of Fisheries MFish hotline: 4 POACHER - In areas where set net fishing is allowed, be careful where and how you use set nets. Stay with your net all the time and check it regularly. Remember it only takes a few minutes to drown a dolphin.
If dolphins are around, take your net out of the water immediately, and encourage others to do the same. Better yet, stop using set nets and only buy sustainable caught fish. With a population estimate of less than 55 Maui's every sighting is important Be boat smart around dolphins. New Zealand law makes it illegal to harass any marine mammal. Make sure you take any rubbish back to shore and please retrieve any abandoned 'ghost' nets that you come across Make sure your rubbish stays out of storm water drains.
Secure lids on bins and pick up any rubbish you see in the gutter or on the beach. Organise beach clean ups or join us for a scheduled event Make a donation to Project Jonah so that we can continue to give these animals a voice.
