Sažetak
Fish farming induces high nutrient loading into the surrounding water that negatively affects the ecosystem. In recent years the occurrence of benthic mucilaginous aggregates has become an increasing problem along the Adriatic Sea coastline. The appearance of these benthic aggregates shows a seasonal pattern becoming noticeable in the field as yellowish tufts in early spring and go on until the end of summer, forming, under favorable environmental conditions, extensive patches at the bottom. The macroscopic development is caused by few filamentous and associated species: Nematochrysopsis marina (Feldmann) Billard and Chrysonephos lewisii (Taylor), two fast growing multicellular benthic chrysophytes, together with a free-living form of the brown alga Acinetospora crinata (Carmichael ex Harvey) Kornmann. The colonial coral Cladocora caespitosa is the only coral that could form reef-like structure in the Mediterranean Sea. The C. caespitosa bank near Kudica Islet (Central Adriatic Sea) occurs at depths from 12 to 16 meters and covers an area of about 150 m2. The bank is 500 m away from the tuna farm cages. Because of the algal bloom the coral bank was covered with a thick carpet of algae every spring and summer. Light deprivation will starve a coral, which is dependent on its symbiotic zooxanthellae to generate food photosynthetically. From 2001 to 2005 more than 90% of C. caespitosa colonies on the bank died because of smothering by algal blooms.
