Dúlra has been actively involved in the following research reports

Basking sharks and plankton in the Erris region

This report focuses on a study of the marine plankton diversity and basking shark distribution within the coastal waters of the Erris region; which was conducted in the summer of 2009 by Dúlra Nature tours and Galway Mayo Institute of Technology.

Marine-wildlife in

Northwest Mayo

A joint effort to enhance the development of Eco-tourism & marine research on the Mullet penisula, which was conducted by Dúlra Nature tours and Machiel Oudejans.

Basking sharks and Eco Tourism in the Erris region

This collaborative study between Dúlra Nature Tours, Machiel Oudejans and members of the Erris Inshore Fishermen Association (EIFA), envisioned to bring together marine research and marine tourism to enhance and sustain both industries in a remote rural area

Bottlenose Dolphins Community Structure in

the North East Atlantic

An investigated of the social structure of bottlenose dolphins in the waters of northwest Ireland and present evidence for distinct inshore and off- shore social communities.  

Bottlenose dolphins in northwest Ireland

A bottlenose dolphin survey was conducted within the coastal waters of northwest Mayo between May and October 2008. The vessel based surveys were conducted using Dúlra na Mara.

Journal paper of bottlenose dolphin in NW Ireland

A research investigation of the distribution, abundance and movement patterns of the bottlenose dolphin in NW Ireland. 

The vessel based surveys were conducted using Dúlra na Mara.


Seaweed Farm

Dúlra has a foreshore licence for a 10 ha aquaculture site in Blacksod Bay with easy access to Blacksod pier, adjacent to the planned research field station. We foresee this as being a valuable study asset which would feed into the research activities of the Field Station. Dúlra foreshore licence permits us to grow nine different species of red and brown Algae. We are currently growing Alaria Esculenta ( Winged Kelp ) on site and our first harvest is due in spring 2019
