Chapt 9C5. Copepod Crustaceans, page 9C5- 7 juvenile salmon prey species Harpacticus uniremis, which occurs in the arctic and as far south as the English Channel in the Atlantic (Kask et al. 1982) and La Jolla, California in the Pacific (Gunnill, 1982). Settling plates appear to be a good way to sample the diversity of harpacticoid and other epibenthic/epiphytic copepods. In each case where we had dock sweep samples to compare with settling plate samples, more species were collected from the settling plates. Only one species, the algal blade dwelling Scutellidium arthuri was found only in the dock sweep samples. Reduced numbers of copepod taxa in the dock sweep samples was probably due to low and/or highly fluctuating surface salinities and/or temperatures. This assertion is supported by the fact that dock sweep samples taken in harbors with high freshwater input (e.g., Valdez, Seward) had extremely low taxa numbers, and those without much freshwater (Homer, Shotgun Cove) had the highest number of taxa. One species of harpacticoid copepod that we found in dock sweep collections, Leimia vaga, may be regarded as “probably introduced”. This species, which was described from Nova Scotia, is also abundant in many estuaries in Oregon and Washington, where it is restricted to brackish reaches (J. Cordell, unpublished data); however, this species was not reported from the Nanaimo estuary by Kask (1982). The fact that L. vaga has restricted habitat requirements and apparently disjunct populations on the Pacific coast may indicate that it has been introduced. Although a number of Asian planktonic copepods have become established in California, Oregon, and Washington estuaries (e.g., Cordell and Morrison, 1996, Orsi and Ohtsuka, 1999), we found no introduced species in the vertical haul samples. In fact, overall planktonic copepod diversity was quite low, and almost all of the copepod numbers were made up of only three taxa: Acartia longiremis, Pseudocalanus spp., and Oithona similis. Also, we did not encounter several taxa that have been previously reported from ballast water arriving to Prince William Sound (Ruiz and Hines, 1997; Hines et al., 1998; Chapt. 3 Biological Characteristics of Ballast Water). As with dock-associated harpacticoids, our shallow sampling depths that were probably subject to large fluctuations in salinity and temperature may have decreased diversity of planktonic copepods in our samples.
