The introduction of nonindigenous aquatic species into the Great Lakes is briefly reviewed. An estimate of the introduction and distribution of ballast water in the Great Lakes by overseas vessels during the 1995 shipping season follows. Recent studies of potential management practices and technologies for nonindigenous aquatic species introduction prevention are also briefly reviewed. With this background, the design of the ballast water filtration demonstration system and its installation onboard the St. Lawrence Seaway-sized bulk carrier M/V Algonorth is then described. This modularized, temporary system uses two automatic backwashing filters in series to filter the ballast water prior to its introduction into a 200 m 3 upper wing ballast tank prepared to serve as the filtration test tank. The filtered ballast water in the test tank will be compared to that in an identical upper wing non-filtration control tank. This system was fabricated and installed in the final two months of 1996 without taking the vessel out of normal service. Following initial testing during late 1996, the system was completed during the winter layup period. It is being utilized for the Phase II test program during the 1997 shipping season.
