Three deepwater fish aggregating devices (FADs) were built, two of which have been deployed along the South coast of Curacao. the objective of the program is to develop duriable FADs which could be anchored at various sites along the coast of Curacao on a permanent basis. The effectiviness of these FADs and their usefulness to the local feet of trolling vessels were evaluated. A Simrad EA300P portable precision echo sounder with a 49KHz transduces was used. The buoys are made of FRP materials and have a spar buoy design. In this report, design considerations, construction detals and deployment methods which may be of use to others are empatized.
