Although the shipping industry has received considerable attention as a dispersal mechanism for aquatic nuisance species, many invasions have been linked to other mechanisms of transfer. These authors assessed species introduction risks associated with seven mechanisms of transfer: seafood companies, aquaculture operations, bait shops, stores that sell ornamental species, research and educational organizations, public aquariums, and coastal restoration projects. They administered a survey of such places in coastal Massachusetts and inquired about (1) their proximity to saltwater and methods of handling live imports; (2) the type and quantity of marine species being imported; and (3) the organization's familiarity with marine invasions. Significantly, no single mechanism of transfer stood out as a primary risk, although most types of operations had characteristics or used handling practices that could facilitate introductions.
