What a brilliant idea. Everyone take what ever crap they have lying around and just go and dump it in the bay and call it an 'artificial reef'. Got an old boat or a few surplus milk crates - just go dump them in the bay and the fish will come. Does anyone really think this can end well? I fully support well designed and planned artificial reef structures which can support and grow fish populations in otherwise desolate areas of mud and silt. The destroyers of productive mangrove and estuaries should be the ones required to offset the losses with compensatory habitat. These ideas are getting traction but the pollies need pushing in the right direction. These ideas need to be built into the next marine park zoning plan for Moreton Bay and not just the simplistic' lock it all up' approach.
