Big step for the ecological balance of the oceans: new ballast water disinfection systems from Germany to curb the global spread of dangerous bio-invaders. According to conservative estimates, around 10 billion cubic meters of water in ship bellies are pumped. This so-called ballast water stabilizes the vessels, prevents the deformation of the hull and thus possible accidents in heavy seas with incomplete loading. The world’s oceans can be navigated so although safer, but the environmental and economic costs of global ballast water transports allow himself doesn’t even begin to appreciate. Bio invaders travel as stowaways as stowaways get to ballast water and travellers along the way that are anything other than welcome when you empty the tanks in their new, distant homeland. The Federal Environmental Agency (UBA) in German ports investigations each year around 2.2 million tonnes of ballast water from non-European regions to be drained. Average It took roughly 1 individual per gallon of ballast water, resulting in a possible entry of 6 million of foreign organisms per day in German waters.
Bacteria, algae, crustaceans, or even fish can colonize suddenly habitats by way of a ballast water tank journey, in which they usually never had to reach. With the local flora and fauna, many of the newcomers have an easy time and displace them from their habitats at sometimes breakneck speed. One of the biggest problems of the marine environment, the introduction of non-native species among the biggest problems of the marine environment. So species such as the American sword shell, spread in the North and Baltic Sea already the originating from the North American East Coast predatory Penilia of Mnemiopsis leydii, the ship Bohrwurm actually dishes large damage a shell -, because he eats away at domestic Woods. Substantial economic losses may arise in the fisheries, if strange jellyfish native fish food or the same Off to eat fish larvae.
