Ship ballast water and various effects on environment

Na gotovo svim današnjim prekooceanskim brodovima ugrađeni su tankovi balasta čija je svrha osiguravanje stabiliteta pri plovidbi kao i ispravljanje poprečnog ili uzdužnog nagiba broda, a posebno u uvjetima kada brod plovi bez tereta ili sa smanjenom količinom tereta. U balastne tankove ukrcava se voda/more iz okruženja, a s time i svi organizmi koji se u tom okruženju nalaze. Mogućnost njihovog preživljavanja tijekom putovanja, ispuštanja u novom području i prilagodbu na nove uvjete može uzrokovati poremećaje u cjelokupnom ekosustavu tog područja. Ovim radom ukazuje se na probleme nastale migracijom invazivnih vrsta diljem svijeta putem balastnih voda, kako se događaju i kako pojedini organizmi opstaju u lokalnim područjima, te njihov utjecaj na ekološke i ekonomske aspekte. Važnost pravovremene reakcije i organizacije u korist suzbijanja dodatnog širenja invazivnih vrsta kako bi se očuvala lokalna flora i fauna diljem svijeta. Napredak u tehnologiji nam svaki dan omogućuje nove spoznaje , pa tako i otkrivaju nove načine kod borbe protiv invazivnih vrstaAlmost all overseas ships today are equipped with ballast tanks, the purpose of which is to ensure stability during navigation and to correct the ships' transverse or longitudinal inclination, especially when the ship is sailing without cargo or with reduced cargo. Water/sea from the environment is loaded into the tanks, and with it all the organisms that are in that environment. The possibility of them surviving during the voyage, being released in a new area and adapting to the new conditions, can cause disturbances in the whole ecosystem of the area. This paper highlights the problems caused by the global migration of invasive species through ballast water, how they occur, and how certain organisms survive in local areas, as well as their impact on ecological and economic aspects. The importance of responding in a timely manner to combat the further spread of invasive species in order to preserve local flora and fauna around the world. Technological progress provides us with new knowledge every day and thus new ways to combat invasive species
