Dolphin conservation in the Shannon Estuary

The Irish Whale and Dolphin Group, along with tourist and fishing boats, conducted 757 boat trips between 2009 and 2018, gathering 300,000 photographs for dolphin identification.

These images were processed and catalogued to collect data essential for conservation efforts.

By participating in this project, tourism boat operators can educate themselves and tourists about the importance of marine biodiversity, dolphin identification, and habitat protection in the Shannon Estuary.

Photo identification images are collected each summer by marine biology students from around the world. These volunteers spend several weeks accompanying research scientists on survey and dolphin tourism boats. The learning objectives include monitoring data such as dolphin population size, home ranges, distances travelled, reproduction rates, and calf survival until adulthood. 

Results

  • Creation of a boat survey protocol to ensure consistent and comparable data over time.
  • Completion of photo identification work, including matching and cataloging trips from 2005-2008, 2009-2011 and 2016-2018, as well as the creation of a Matching Guide.
  • Establishment of the home range of the Shannon dolphin population.
  • Identification of key foraging sites and important prey species, such as Atlantic salmon.
