An estimated 30,000 humpback whales travel along the east coast of Australia as they migrate between their tropical breeding grounds and polar feeding grounds. Traditionally, these whales were only thought to eat when they arrived in Antarctica. However, in recent years, observations suggest an increasing abundance of whales stopping in Tasmanian waters to “have a snack” and refuel as they migrate.
The Tasmanian Whale Fluke Project is investigating the importance of Tasmanian waters to the migrating East Australian humpback whale population as a migratory stop over. To do this we collect images of humpback whale flukes and as well as behavioural observations from vessels of opportunity. The fluke is the underside of the whale’s tail and is unique to each individual whale, a bit like a giant fingerprint. Using these images, feeding observations, prey, and environmental data we aim to provide new insights into the residency times of humpback whales in Tasmanian waters and what drives these feeding events.
With climate driven changes in prey dynamics and the increasing risk of entanglements and vessel collisions, understanding local habitat use and feeding events is critical for the long-term management and protection of humpback whales in Tasmanian waters.
100% of funds donated to this project will be spent on deploying observers, acquiring field equipment to collect prey and environmental data, as well as the analysis and delivery of results to the scientific community and end users.
