Abstract Major El Niño events and oceanic heat waves are linked to the range expansion of many marine species. For the shores of the northeast Pacific, we compared range expansion in the European green crab, Carcinus maenas, which was introduced to San Francisco Bay prior to 1990, to that of the native lined-shore crab, Pachygrapsus crassipes, which has existed on the coast since at least the end of the last Ice Age (>10,000 years ago). The initial northern range limit of these species was central California and central Oregon, respectively. Both species increased their northern range along the open coast to northern Oregon, Washington and Vancouver Island after strong El Niño events. C. maenas, however, in just a matter of decades, successfully established populations in inlets on the west coast of Vancouver Island, and possibly also in the Salish Sea, while P. crassipes, in thousands of years, never has. We hypothesize that this difference in invasion success is due to the shorter larval duration of C. maenas, < 2 months, compared to that of P. crassipes, 3-4 months and timing of larval release, winter for both species. Because the residency times of water in the inlets of the west coast of Vancouver Island are ~1-2 months, they can act as an incubator for the larvae of C. maenas, while those of P. crassipes are likely flushed out to the open sea before they can complete their development.

Abstract Behrens Yamada, S., and Gillespie, G. E. 2008. Will the European green crab (Carcinus maenas) persist in the Pacific Northwest? – ICES Journal of Marine Science, 65: 725–729. A strong cohort of young European green crabs (Carcinus maenas) appeared in North American embayments from Oregon to the west coast of Vancouver Island following the strong El Niño of 1997/1998. Unusually, strong north-moving coastal currents transported crab larvae from established source populations in California to the Pacific Northwest. Since then, both coastal transport and recruitment of young green crabs have been weaker. Although it was predicted that green crabs would become extinct in the Pacific Northwest once the original colonists died of senescence at about age 6, this has not happened. Age-class analysis and the appearance of young crabs evidence the existence of local recruitment in the Pacific Northwest, especially after warm winters. An extensive survey by Fisheries and Oceans Canada found populations of green crabs on the west coast of Vancouver Island, with densities of >2 per trap in some inlets. However, no green crabs were found in the inland sea between Vancouver Island and the mainland. Therefore, outreach efforts should continue to prevent the establishment of this invader in those waters via ballast water or shellfish transport.

Rate Of Success

The European green crab (Carcinus maenas) is a destructive marine invader that was first discovered in Newfoundland waters in 2007 and has since become established in nearshore ecosystems on the south and west coast of the island. Targeted fishing programs aimed at removing green crabs from invaded Newfoundland ecosystems use Fukui traps, but the capture efficiency of these traps has not been previously assessed. We assessed Fukui traps usingin situobservation with underwater video cameras as they actively fished for green crabs. From these videos, we recorded the number of green crabs that approached the trap, the outcome of each entry attempt (success or failure), and the number of exits from the trap. Across eight videos, we observed 1,226 green crab entry attempts, with only a 16% rate of success from these attempts. Based on these observations we believe there is scope to improve the performance of the Fukui trap through modifications in order to achieve a higher catch per unit effort (CPUE), maximizing trap usage for mitigation. Ultimately, a more efficient Fukui trap will help to control green crab populations in order to preserve the function and integrity of ecosystems invaded by the green crab.
