I am working on the interaction of Irrawaddy Dolphins and fishing gears in a bay in the Philippines. Too much number and kinds of gears sometime accidentally entangle and kill dolphins. I need suggestions from experience on management approach that would keep dolphins from entangling in nets and ropes at the same time will not greatly affect the source of income of the fishers?
Hi Benjamin,
I've worked on studies on the west coast of Canada where whales have been a problem in some gears (especially gill nets) and one solution has been to use 'pingers'. These emit sounds that deter marine mammals, and are used throughout North America. If you do a web search for marine mammals and pingers, you'll find quite a bit of info.
Good Luck.
Thank you Arvind and Shawn. Yes, I will go through these references and web sites. This are valuable inputs! We hope to move on this situation and help save and manage fishers and dolphins. Will keep in touch.
