Had an incredible sighting off Nanao Island Shantou, China of humpback dolphins. There are only 12 left of the local population and we spotted a group of 6 while driving! We stopped the car, caused minor traffic chaos but managed to get some photos including id's! My first car based survey!

In China invited by Shantou University attending the Pacific Science Congress and to build collaboration for marine megafauna research & conservation.

Our final paper for 2024: link.springer.com/article/10.1...
We provide rmax & fishing mortality for Endangered Spinetail & Bentfin Devil Rays. We demonstrate an approach to assess data-poor species. Urgent need to reduce catch of all devil rays to prevent species extinctions. @iucnshark.bsky.social

Need a festive season read in front of the fire?

We hope this paper published today In Marine Mammal Science will be of interest. We demonstrate the application of PAM and signature whistles to estimate abundance of bottlenose dolphins with comparable results to Photo-ID.

We hope this new paper will be useful for colleagues working in data poor areas or for anyone else thinking of using questionnaires to assess fisheries catch and bycatch. @sscmarine.bsky.social @seaaroundus.bsky.social
✨ New Publication ✨

📝 Our systematic review on questionnaire surveys investigating marine mammal bycatch is now available! Discover best practices for designing + conducting questionnaires to collect data that can be used to protect these species🐬 @perberggren.bsky.social

In other areas e.g. off the UK, development of offshore windfarms has had a positive effect on harbour porpoise occurrence. Wind turbines create a reef effect leading to increased foraging opportunities for whales and refuge from shipping and fishing activities: link.springer.com/article/10.1...

Hi, introducing myself to the bluesky community. I am a marine megafauna conservation biologist. I conduct research & develop low-cost methods for assessment of marine mammals, sharks & rays and methods to mitigate threats to these animals. Hoping together we can improve the marine environment.
