Quantifying potential propagule pressure of aquatic invasive species from the commercial shipping industry in Canada
We quantify and compare different measures of potential propagule pressure (PPP) of aquatic invasive species (AIS) from commercial vessels in Canada. We used ship arrivals and ballast water discharge volumes as proxies for PPP from ballast water organisms, and wetted surface area (WSA) as a proxy for hull fouling PPP, to determine their relative contributions to total PPP. Our study illustrates benefits and limitations of using different PPP proxies to estimate invasion risk.

In our study we quantified the PPP of AIS from shipping activities to all major Canadian shipping ports in the Atlantic, Great Lakes-St. Lawrence, and Pacific shipping regions. To our knowledge, this is the first such comprehensive analysis of propagule pressure on a national scale (but see DiBacco et al. (2011) for an analysis of ballast water zooplankton densities for vessels transiting Port Metro Vancouver and several East coast ports).

- Description
-
Data were grouped according to three major shipping regions in Canada: the Atlantic coast, GLSL and Pacific coast. Ports east of Quebec City were classified as Atlantic ports, as the limit of saltwater intrusion is usually at Quebec City or at Île D’Orléans, just west of Quebec City (Gobeil, 2006). In the Pacific region, Port Metro Vancouver sub-ports and regions (Fraser Port, Vancouver Port-Burrard Inlet, Roberts Bank, Port Moody) were treated separately in our analysis as they are geographically distinct and ballast water data were available for each sub-port.

We quantify and compare different measures of potential propagule pressure (PPP) of aquatic invasive species (AIS) from commercial vessels in Canada. We used ship arrivals and ballast water discharge volumes as proxies for PPP from ballast water organisms, and wetted surface area (WSA) as a proxy for hull fouling PPP, to determine their relative contributions to total PPP. For three regions studied, PPP proxies correlated significantly across ports and some vessel categories. Relative contributions of ship arrivals, ballast discharge, and WSAs to PPP, evidenced by non-significant correlations across these measures, varied across regions, ports, vessel types, and seasons. Flow-through (dominant on east and west coasts) and empty-refill (in Great Lakes-St. Lawrence region) were the major ballast water exchange methods employed by the vessels surveyed. These methods have different biological efficacy for AIS removal, influencing PPP. Our study illustrates benefits and limitations of using different PPP proxies to estimate invasion risk.
