Obsolete - AFSC/RACE/GAP/Orr: NPRB_1016 An annotated checklist of the marine macroinvertebrates of Alaska and a retrospective analysis of the groundfish trawl database.

A comprehensive species list of marine invertebrates of Alaska has been lacking. The checklist of Austin (1985) treated the marine invertebrates of the southern coast of Alaska to California and since then many new species have been described, many range extensions have been discovered, and considerable changes in higher-level systematics have been made. The checklist we compiled lists over 3,500 species and includes the currently accepted scientific name and its significant synonyms, common names, type localities, geographic and depth distributions, a general statement of abundance in Alaska when known (e.g., rare, uncommon, common, abundant), and general remarks. This checklist will serve as a foundation for future species-specific research. Updated species lists are necessary to reflect the current state of biodiversity knowledge and are thus essential for conservation planning and management. To monitor and predict future changes to marine life, the distribution and abundance of marine species need to be better understood, and this can only be achieved with reliable identifications based on a sound taxonomy. The current status and future directions of Alaskan marine invertebrate biodiversity are briefly discussed.

User must read and fully comprehend the metadata prior to use. Applications or inferences derived from the data should be carefully considered for accuracy. Acknowledgement of NOAA/NMFS/AFSC, as the source from which these data were obtained in any publications and/or other representations of these, data is suggested.

This checklist is focused on macroinvertebrates, a term used loosely here to refer to an invertebrate that is large enough to be seen without the use of a microscope or, specifically, one that is retained on a 0.5 mm sieve. Macroinvertebrates that are typically encountered through trawling are emphasized. Some groups, such as the nematodes, oligochaetes, copepods, and uniramians, which qualify as macroinvertebrates were not included because of their poor representation in trawls, as well as a general lack of knowledge about these groups. The statement of abundance is primarily based on data obtained from the Alaska Fisheries Science Center (AFSC) trawl catches, augmented with information from other accounts. When noted, abundance refers only to the presence of the species in Alaska and is not noted when abundance is unknown or uncertain. Full citations are provided for publications listed in the introduction of each major taxonomic group and for references used in the ¿Remarks¿ section under selected species. No attempt was made to include full taxonomic citations for each valid name or synonym. Information gleaned from online databases was checked against either original sources or the secondary literature in order to ensure accuracy. Some published species lists developed from surveys of geographical regions did not indicate how species were identified. These species were not included without additional documentation from other sources.
