Sažetak
Recent climate change and increasing temperatures resulted in important impacts on mariculture and fishery in Adriatic waters. These impacts are expressed in different ways. Overall impact of climate change on the Croatian fishery and mariculture sector is complex, as the impacts are both nd positive. They include changes in the marine environment, changes in migration patterns of fish on the open sea (including pressure to migrate in cold water species), potential changes in the growing season and rearing time for farmed fish, and the potential increase of invasive species, which has increased catches of certain new species but threatened the production of others. Warm-water species in Adriatic are extending their range northward. Two factors influence these migrations: demographic expansions, which affect individual species, and climatic fluctuations, which shift species biogeographical boundaries. As an example bluefish, Pomatomu saltator were first recorded in 2004 un the Northern Adriatic, where it is was unknown to fishermen. The fish is a typical predator, preying mainly on grey mullets. It also appeared several years ago in the Neretva river estuary, where grey mullet fisheries are the most important segment of the local fishery. In only a few years, bluefish decimated grey mullets in the area. The most fragile maricukture species is flat oyster, Ostrea edulis, which suffer high mortalities when temperatures exceed 26C as already observed in Mali Ston Bay culture area. In Croatia and elswhere it is critical that adaptive managament practices should be implemented combined with an increased level of knowledge about likely impacts of climate changes in the short and long term.
