  • Blog Post: Making the best of a bad situation

    Unfortunately seabirds caught as byctach in pelagic longline fisheries are generally only brought onboard once they are already dead (they are hooked and drown during the set when lines sink into the water). In Uruguay birds killed at sea are returned to the laboratory for analysis. By doing so we can...
  • Blog Post: Experiments aboard commercial longline vessels in Uruguay

    In my most recent trip to sea, we set off for a period of eleven days from the port of La Paloma, located on the east coast of Uruguay. We had already partaken in various trips on this vessel, and so the crew already knew us well and they were happy to collaborate with our work again. We now have a much...
  • Blog Post: Collaborating with the crew to refine bird-scaring lines

    For this blog I am posting on behalf of my friend and colleague Rodrigo Forselledo: Rodrigo wrote the following: As Sebastian is enjoying a short period in the UK, I have taken on his ATF duties in Uruguay. On my first pelagic longline trip I started testing the new design of the bird-scaring...
  • Blog Post: Southern Brazil and Uruguay, a sea of similarities

    Last month I returned from my most recent trip, this time aboard on the FV Maria , the same longliner that I had worked with last winter. We spent 19 days at sea and conducted 15 longline sets. In order to minimize seabird interactions all these sets were performed with a tori line deployed and were...
  • Blog Post: Improving tori lines in Uruguay

    This last trip to sea was onboard a vessel dedicated to catching swordfish and tuna. My goal was to continue experimenting with the tori lines we have been designing and testing in pelagic fisheries in Uruguay. We conducted seven fishing operations, three with a tori line and four without. Despite...
  • Blog Post: Swings in fortune at-sea in Uruguay

    Continuing with the tori line experiments in the pelagic longline fishery, I headed back to sea but this time aboard the RS Aldebran, Uruguay’s research vessel. On this last trip we spent 20 days at sea, with a short break at the start due to a faulty hydraulic pump forcing us to return...
  • Blog Post: Modifications to Uruguayan bird-scaring lines

    The streamer line, also known as a bird-scaring or tori line is a mitigation measure that reduces seabird bycatch in longline fisheries. It is recommended that they be used in combination with night setting and line weighting. The efficiency of streamer lines has been demonstrated by our team in the...
