Aggregation behavior is one of the important features in the ecology of tuna species, which makes them susceptible to fishing gears such as purse seines targeting aggregating fish (Hilborn 1991).As a primary target species of tuna purse seines, skipjack not only have a tendency to form single or multi-species free schools in nature (Stöcker …

The use of FADs has been increasing since the mid 90's and are becoming more common all over the world. For instance, nowadays, approximately 70% of purse seine tropical tuna fisheries depend on FAD (Hallier & Gaertner, 2008). FADs may be an effective method for more efficient tuna fishing, but these devices are said to be one of …

Abstract. In the past two decades, drifting fish aggregation devices (FADs) have revolutionized pelagic fisheries, and are now responsible for the majority of tuna purse seine catches. Here, we argue that by taking advantage of the same proven aggregative properties, FADs could be used to enhance the benefits provided by blue water marine ...
