The International Maritime Organization and U.S. Coast Guard have implemented regulations to reduce introductions of non-indigenous species via ballast water (BW). For phytoplankton, regulations limit discharges to less then 10 live/viable cells mL-1 (size 10-50 μm), ignoring other size fractions. Additionally, challenge conditions of 100 (shipboard) and 1000 (land-based) cells mL-1 are required in BW management system certification testing. How these requirements correspond to natural phytoplankton populations is poorly re
