Our action revolves around three principles:

Observe, Understand, Share.

The GEMM therefore functions as an observatory in itself, making it possible to understand and assess the way of life and behavior of marine mammals in their natural habitat and as a medium for exchanging , possibly comparing (biomimicry) and making the voice heard. voiceless.

In Polynesia, the GEMM was the first to draw up an inventory of the problems encountered by marine mammals in their sanctuary.

Different biases can be used to bring these principles to life. Science, but also art, philosophy, culture, information and ethics can be, separately or together, the object of our efforts.

In Polynesia as elsewhere in the world, we see a strong development of activities

whale and dolphin watching and approach in the wild. These activities most often surf on myths and legends involving these emblematic animals to promote non-reasoned and poorly framed approaches that disturb and tend to weaken populations of marine mammals - mainly the humpback whale, the bottlenose dolphin and the bottlenose dolphin. long bill - in Polynesia, disrupting their behavior , their way of life and their environment .

Since 2009, the GEMM has been carrying out voluntary monitoring of dolphins and whales affected by tourism in the Tuamotu and Society archipelagos. Detailed scientific monitoring was carried out in particular from 2009 to 2019 on the effects of diving tourism on the behavior of bottlenose dolphins in Rangiroa atoll.

The scarcity of marine fauna in Polynesia generates increasingly acute problems between fishermen and marine mammals, including depredation behaviors in which animals remove, partially or totally, bait or catch from fishing gear. Cetaceans can then be victims of accidental catches or reprisals from exasperated fishermen. Globally, the false killer whale represents two thirds of the species identified, killed or seriously injured in fisheries, exceeding in certain places

people's resilience. Pilot whales are not left out, since a decline in their populations has also been observed in Hawaiian waters. This

The problem is all the more important since mortality rates are often underestimated. The populations of small cetaceans are also very threatened according to the fishing techniques used (Bay of Biscay). Since 2012, the GEMM has been working on a better understanding of the problems of coastal and deep-sea depredations in the Society, Tuamotu and Marquesas archipelagos in partnership with CRIOBE, DRMM and certain captains of Polynesian fishing vessels.

Less well-known problems, such as famine , diseases and poisonings linked to pollution and global warming, would also deserve more efforts but especially resources that we do not have.
