Tunnel nets are used along the coast or in estuaries in southern Queensland to target many species. The net is constructed of two long wings and a central pocket or ‘tunnel’. The net is staked in position to form a large arrow shape, with the wing ends circling inwards to lead escaping fish back into the net. The net relies on fish encountering the net as they move with the receding tide. The fish become concentrated in the tunnel, which remains in the water at low tide. The tunnel section is finally lifted on board a dinghy and emptied.
