New system design for the cultivation of extractive species at exposed sites -Part 1: System design, deployment and first re-sponse to high-energy environments
The purpose of this publication is to perform a system analysis of new cultivation technology for exposed bivalve farming. The technical feasibility of the new construction, called Shellfish Tower, was assessed. The device has gone through several very different phases of development on its way to t...
