It has been proposed that a wrecked aircraft, located on an island within a marine national park in East Africa, be sunk to form an 'artifical reef'. I am looking for information on the possible positive and/ or negative impacts this might have, as well as whether such project would increase fish production or simply aggregate existing fishes. In addition, a better understanding of any possible problems (e.g. contamination of the water by paints on the metalwork) and of how to select the most appropriate site are needed.
I have a good understanding of how to conduct BACI studies to reveal what the impact on the area is, should the object be sunk. But in order to decide whether this should even happen, I am first looking for information from previous projects of a similar nature. Any comments or references would be appreciated.
