FAD Module
A fish aggregating (or aggregation) device (FAD) is a man-made object used to attract ocean going pelagic fish such as marlin, tuna and mahi-mahi (dolphin fish). They usually consist of buoys or floats tethered to the ocean floor with concrete blocks. Over 300 species of fish aggregate around FADs in the open ocean around the world; the reasons behind aggregation are numerous and vary for each particular fish species. Fish tend to move around the FADs in orbits of differing dimensions, as opposed to remaining stationary underneath the buoys. They are deployed for use by both recreational and commercial fisheries and there are several types; natural drifting FADs (such as logs) and man-made FADs which can either be drifting or moored so that they float at the surface or lie subsurface. Subsurface FADs last longer due to less wear and tear from surface tension, but have the disadvantage of being harder to locate. You can find the photos from Ege University FAD Project, which the modules is using that I design for.
