The Txori Argi fishing trawler in port. The Spanish flagged Txori Argi is the fifth largest tuna purse seiner in the world, contributing to the depletion of yellowfin tuna stocks across the Indian Ocean. The vessel operates with purse seines and takes advantage of Fish Aggregation Devices (FADs) to attract tuna. Unfortunately, FADs attract other marine species as well, and therefore create bycatch of Pacific silky and Oceanic whitetip sharks, vulnerable whale sharks, threatened sea
turtles and seabirds.
