Behavior of yellowfin (Thunnus albacares) and bigeye (T-obesus) tuna in a network of fish aggregating devices (FADs)

open access: yes, 2007
The influence of multiple anchored fish aggregating devices (FADs) on the spatial behavior of yellowfin (Thunnus albacares) and bigeye tuna (T. obesus) was investigated by equipping all thirteen FADs surrounding the island of Oahu (HI, USA) with ...
