“…We studied the potential impacts of SSWD in the Salish Sea, an inland marine ecosystem shared between British Columbia, Canada and Washington State, United States [18]. Based on subtidal sills and oceanic and freshwater flow patterns, oceanographers divide this 16,925 km 2 transboundary ecosystem into 6 sub-basins: the Strait of Georgia, Northern Straits, Whidbey Basin, Central Basin, Hood Canal, and South Puget Sound [19,20].…”

Sea star wasting disease devastated intertidal sea star populations from Mexico to Alaska between 2013–15, but little detail is known about its impacts to subtidal species. We assessed the impacts of sea star wasting disease in the Salish Sea, a Canadian / United States transboundary marine ecosystem, and world-wide hotspot for temperate asteroid species diversity with a high degree of endemism. We analyzed roving diver survey data for the three most common subtidal sea star species collected by trained volunteer scuba divers between 2006–15 in 5 basins and on the outer coast of Washington, as well as scientific strip transect data for 11 common subtidal asteroid taxa collected by scientific divers in the San Juan Islands during the spring/summer of 2014 and 2015. Our findings highlight differential susceptibility and impact of sea star wasting disease among asteroid species populations and lack of differences between basins or on Washington’s outer coast. Specifically, severe depletion of sunflower sea stars (Pycnopodia helianthoides) in the Salish Sea support reports of major declines in this species from California to Alaska, raising concern for the conservation of this ecologically important subtidal predator.

“…The objectives of the action agenda are heavily weighted toward achieving tangible habitat and restoration goals through the cleanup or remediation of environmental contaminants and the reduction of nutrient loadings. Further, numerous salmon recovery plans, the Georgia Basin Action Plan, and other restoration efforts are intended to bridge national and international jurisdictional boundaries in the Salish Sea (Gaydos et al 2008); however, none have incorporated the effects of disease into their restoration plans for marine fishes or other marine animals. These oversights are unfortunate, because massive disease epizootics repeatedly cause drastic population declines and extirpations in wild animal populations (Smith et al 2009), including populations of marine fishes (e.g., Jones et al 1997;McVicar 1999).…”

Enfermedades infecciosas en los peces del mar de SalishRESUMEN: Tal como sucede en las regiones marinas de otras partes del mundo, los peces del mar de Salish hospedan cantidad de patógenos, incluyendo nematodos, tremátodos, protozoarios, protistas, bacterias, virus y crustáceos. En este trabajo se hace una revisión de algunas de las enfermedades infecciosas mejor documentadas que muy posiblemente contribuyen a la pérdida significativa de peces en el mar de Salish y se discuten los factores ambientales y ecológicos que pueden influenciar los impactos de la enfermedad a nivel poblacional. La demostración de estas enfermedades y sus consecuencias en recursos críti-cos y amenazados, justifica expandir la vigilancia sobre patógenos e incorporar un pronóstico de enfermedades y herramientas de mitigación en los esfuerzos de restauración de ecosistemas.ABSTRACT: As in marine regions throughout other areas of the world, fishes in the Salish Sea serve as hosts for many pathogens, including nematodes, trematodes, protozoans, protists, bacteria, viruses, and crustaceans. Here, we review some of the better-documented infectious diseases that likely contribute to significant losses among free-ranging fishes in the Salish Sea and discuss the environmental and ecological factors that may affect the population-level impacts of disease. Demonstration of these diseases and their impacts to critical and endangered resources provides justification to expand pathogen surveillance efforts and to incorporate disease forecasting and mitigation tools into ecosystem restoration efforts.

“…Although prior studies suggest that rehabilitated harbor seal pups behave and likely survive similar to wild weaned pups, these results are not easily applied to San Juan County, which is part of a unique inland sea (Gaydos et al . ) where the harbor seal population is at or near carrying capacity (Jeffries et al . ).…”

Harbor seal (Phoca vitulina richardii) populations in the inland waters of Washington and British Columbia are at or near carrying capacity. Stranded pups often are collected and admitted to rehabilitation centers, and then released when they reach a weight of 22 kg and meet a variety of preestablished health and release conditions. While rehabilitation is common practice, it is unclear if rehabilitated seal pups behave like wild weaned pups. Using satellite transmitters, we compared movement patterns of 10 rehabilitated pups with 10 wild weaned pups. When released, rehabilitated seals were longer and heavier than wild pups, while wild pups had a larger mean axillary girth. No clinically different blood parameters were detected. On average, rehabilitated harbor seal pups traveled nearly twice as far cumulatively, almost three times as far daily, and dispersed over three times as far from the release site compared to wild weaned seals. Additionally, wild harbor seals transmitted nearly twice as long as did rehabilitated seals. These patterns suggest that learned behavior during the brief 3–4 wk nursing period likely enables wild harbor seal pups to move less daily and remain closer to their weaning site than rehabilitated pups.
