... In-tank sampling points facilitate to access ballast water directly from a tank through ballast tank manholes, sounding, or air pipes. In-line sampling points comprise the ballast water pumps and pipelines of the ship (Consult, 2013), and have been used in a number of previous studies (David and Perkovič, 2004;David et al., 2007;Gollasch, 1996;Rosenthal et al., 1999). The present study used the in-tank sampling method, in which three samples were taken from a manhole. ...

... The concentration of viable zooplankton organisms observed is in a similar range as documented in other ballast water studies considering ballast water uptake sampling (Lavoie et al. 1999;Gollasch et al. 2000;Olenin et al. 2000;McCollin et al. 2007bMcCollin et al. , 2008Simard et al. 2011;Maranda et al. 2013;Briski et al. 2015). ...

Testing Ballast Water Management Systems: Challenge Water Conditions During More Than 100 Test Voyages

... While it is true that aquaculture has been a minor source of exotic species introduction in the marine environment by comparison with ballast water in ships (Gollasch et al., 1999), a number of exotic aquatic vertebrates have been introduced as a result of fish farming. In response to an increased awareness of the risks posed by species movements, various international codes of practice, such as those developed by EIFAC, ICES and FAO (Turner, 1988;ICES, 1995;FAO Fisheries Department, 1997), and a range of regulations and laws have been introduced, greatly reducing the risk of unwise introductions. ...

... Findings of larger organisms in ballast tanks do therefore indicate that species were either pumped on board as eggs or younger larvae and were growing inside a tank, or that reproduction has possibly even occured inside a ballast tank. In fact, Gollasch, Rosenthal, et al. (2000) found by daily samplings of the same ballast tank on an approximately 3-week voyage an increasing number of copepods in a tank and they concluded that reproduction occurred inside the tank during this voyage. ...
