SELECTIVE DSF (ISD+)
species identification for selective fishing
At Satlink, we adapt the latest acoustic studies to the fishing industry. This is how our innovative Selective DSF was born. It is a powerful technological tool aimed to contribute to the sustainability of tuna fishing around fish aggregating devices (FADs). Its unique double echo-sounder system allows fleets to obtain accurate information on the tonnage of fish present under the DSF and the composition of the different commercial tuna species. This is how it becomes the perfect aid to plan detailed fishing strategies and optimise fishing pressure, protecting stocks through efficient and sustainable fishing.
Its unique simultaneous double sounding system provides information on the composition of species under the DSF. It reports the percentage of the top three tropical tuna species, together with total estimated tonnes, for a more informed, efficient and sustainable fishing strategy.
A must for decision-making, it allows easy viewing of biomass movement under the DSF during key tuna fishing hours. During the two hours around sunrise, the buoy takes soundings every minute and creates a graph to report what is happening under the buoy.
New! The Selective DSF’s new motion sensor now sends information to easily identify situations such as the possible sinking or recovery of a buoy. Tilt and shock warnings, as well as status messages, help to know the status of the DSF in depth, at any time.
The most advanced technology in its field. By using the ‘chirp’ pulse, it distinguishes plankton and other interferences much more accurately, giving much more precise estimates. In addition, its more efficient energy management means that the DSF can sound more frequently and send a greater amount of information.
