The significance of fouling investigations for the estimation in the construction of marinas

Abstract

       In the Veruda Bay (Pula), due to the intention to construct new marinas, investigations were undertaken at the time of anchoring of navigable objects, in situ, at the entrance, in the middle and in the inner part of the bay.

       Quality, intensity and dynamics were of a typical port character, with dominant bioindicators of organic pollution (Hydroides elegans, Janua pseudocorrugata, Balanus amphitrite amphitrite).

       On the basis of biological characteristics and ecological indices, high pollution level signs were found in the inner part of the bay, where dystrophic and eutrophic conditions were noticed. Therefore, this part of the bay is not recommended for the extension of boat berths.
