>I'm kind of surprised that ballast water isn't somehow sterilised
Ballast water probably has too much mass to be boiled cost-effectively. We're talking thousands of tonnes of water in some cases.
UV isn't a bad idea, but probably wouldn't work well for well-protected species like bivalve molluscs. Unfortunately, those are some of the most invasive species that we have -- see Zebra Mussels, for instance.
