Catalog of
foto-identification

Of the total record of sightings of humpback whales through boat monitoring, 39 individuals were identified through the photo-identification technique, using only photographs of the caudal fin.

In some cases, during the sighting it was not possible to take a photograph of the caudal fin of the individuals. In this case, there is a record of dorsal fins, which could help photo-identification in the following winter migration season of the humpback whale.

Wounded or
collision-damaged whaled

During the monitoring by boat this season, specimens of humpback whales have been observed on occasions with marks of wounds or mutilations on their caudal fin.

The concentration of boats, the non-compliance with the established distances or the lack of speed control of the boats are factors that can affect the physical well-being of these large mammals, hence the great importance of generating greater awareness among the sector that offers this type of tourist service, the local community and occasional visitors.

From our field of action we want to contribute by making a special mention about the sightings of individuals who presented this type of marks, with the purpose of opening and continuing in the coming seasons a line of work on this issue, providing information and reports on human impacts on marine life.
