Sydney East Fad - Deployed


Thunder

Recommended Posts

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.

Are the FADs simply rope and buoy in Australia or are they like the overseas ones where they attach some older ropes under the surface so it has a bigger floating reef "footprint". Guess the blokes spearing around them last year could have told me or were they just collecting all the lead and jigs?

Thanks Mariner

The photos ( can't find them now) I have seen from OS show that the buoy supports a couple of "mini Reefs" in the top of the water column made up of old rope etc that "reefs"up quicker to create more diverse FAD quicker and also support more fish at different depths. They had a larger buoy and a couple of suppoty buoys like 20 and 50 feet under water. Act like a mini reef rather than just a reference point for fish. Ones in the aussie photos just look like buoy on a rope unless the Port Maq trial was trailing a underwater sheet webbing net to give more surface area.

Cheers

You drinking beer in Syd yet?
