TRANSPORTABLE DEVICE FOR COLONIZING AND HARVESTING INVERTEBRATES AND ITS USE

摘要

The aim of the invention is to establish a colony of and harvest vagile benthic animals, in particular crabs, including on structured and inaccessible beds of bodies of water. To that end, the device (01) according to the invention has either side of a central hinge (06) two auxiliary hinges (11) by means of which frames (03) can be positioned at different opening angles (.THETA.) of the device (01) such that it can also be adapted to structured beds of bodies of water (02). The device (01) is hoisted and lowered in the collapsed or folded form, and is laid out in the folded or fully open form. Tubular components (15) improve drift and are particularly attractive as a habitat for crabs. The device (01) according to the invention can thus be used as an artificial reef to establish a colony and as a trap for effectively harvesting crabs in the immediate surroundings of wind turbines in offshore areas.
