WATCH: Scientists test method to save sharks incidentally caught in tuna purse seine net

A new video shows scientists testing a method to save sharks incidentally caught in a tuna purse seine net. 

ISSF tests best practices for bycatch mitigation and sharing these findings through scientific reports, info-graphics and now video. The findings of this particular video were encouraging, with electronic tag data showing that 100 percent of tagged sharks survived past 21 days post-release.

ISSF believes this could be a relatively simple way for fishers to prevent sharks from becoming entangled when they’re caught in nets, and to free them quickly without harm.
