Abstract: The collector habitat device comprises panels of non-biodegradable and/or synthetic fibrous material set in durable weatherproof frames and attached to a base; when placed in, the panels hang within the water column providing numerous parallel settlement surfaces for post-larvae. A float assembly, optionally attached to the opposite side of the base from the panels, allows the device to float just below the water's surface. The collector habitat device also incorporates a guard, surrounding the panels, with apertures to allow settlement-stage post-larvae access to the settlement surfaces, while preventing larger organisms and potential predators from gaining access. The collector habitat device also, optionally, incorporates an optionally removable/re-attachable reservoir hung below the guard; and an optional olfactory attractant delivery device.
