Sažetak
Before eradication, at the end of 1997, one large and five small stations existed in the Starigrad Bay (43°10’54’’N-16°35’00’’E)(Hvar Island, Adriatic Sea, Croatia), covering 36 100 m2 of the affected surfaces of 122 500 m2 with 1955 m of the affected shoreline in total. In October 1977, eradication of border algae colonies was carried out at the central station, and complete eradication of algae was done at all of the remaining smaller stations. The purpose was to prevent further expansion throughout the bay. Eradication was done manually with the aid of a suction pump and by covering the colony with black PVC foil. The eradication process lasted 15 days, and included 8 divers (202 hours of total diving time). Manual extraction was utilised, and with the aid of a suction pump, 250 m2 of smaller individual colonies was extracted. In total, 512 m2 of the algae colonies was covered with black PVC foil ( aprox. 900 m2 of black PVC foil was used). In January 1998, the covered alga had completely disappeared. During the Summer 1998 the manually eradicated area had a sporadic reappearance of algae.
