2 April 30 - May 2, 2014 Washington State Convention & Trade Center Seattle, Washington Marine Birds and Mammals of the Salish Sea: Identifying Patterns and Causes of Change The Salish Sea in FishBase and SeaLifeBase MLD Palomares and N Bailly 1 May

3 Objectives of the study Document the marine biodiversity of the Salish Sea and its subecosystems in FishBase and SeaLifeBase; Complete this documentation at least for vertebrates.

4 The Salish Sea in FishBase and SeaLifeBase April 2014 version 2,280 marine species assigned to the Salish Sea based on about 100 references Biological data from 165 references

5 Compared with previous studies Number of species FishBase/SeaLifeBase 82 references all together Marine mammals Sea birds Pisces Tunicata Annelida Arthropoda Bryozoa Chlorophyta Cnidaria Ctenophora Echinodermata Mollusca Nemertea Ochrophyta Phoronida Platyhelminthes Porifera Rhodophyta Sipuncula Gaydos et al. (2008, 2011) Cowles (2005)

6 Salish Sea fishes in FishBase (n=238) Ray Troll Checked by Andy Lamb and Eric Taylor Checked against Peden (2002) Will be checked against Pietch and Orr 85% based on: Hart (1973), MacAllister (1990) Clemens et al. (1961) Favaro et al. (2010) Williams et al. (2010) 25 other orders Pleuronectiformes Scorpaeniformes Salmoniformes Perciiformes

7 Simple profiles Very low Lmax=233 cm TL=3.57 Low Lmax=96.7 cm TL=3.70 High Lmax=14.1 cm TL=3.31 Medium Lmax=39.2 cm TL=3.44

8 Trophic pyramid Trophic level estimates from diet composition and food items. Top predators: large species

9 Salish Sea marine species in SeaLifeBase Mike A. Yap, SeaLifeBase >90% based on : Macdonald et al. (2010);Lamb et al. (2011); Pacific Northwest Shell Club (2014); Schoch and Diether (2001); Marliave et al. (2011); Lambert and Austrin (2007); Gaydos and Pearson (2011); Backe et al. (2011); Elahi (2012); and Lambert (2000). Sea birds Nemertea Ochrophyta Porifera Tunicata Bryozoa Marine mammals Rhodophyta Cnidaria Echinodermata Mollusca Arthropoda Pisces Annelida

10 Trophic pyramid Trophic level estimates from diet composition and food items. Top predators: seabirds and cetaceans Also available for Puget Sound and Strait of Georgia

11 How about the Salish Sea?

12 Missing data in FishBase and SeaLifeBase 68% of fish species have biological data in FishBase; Only about 14% of non-fish metazoans, including some species with CR status in IUCN, have data in SeaLifeBase; groups not well covered are: Cnidaria, Annelida, Kamptozoa, Kinorhyncha, Nemertea, Platyhelminthes, Porifera and Sipuncula; Data gaps include diet composition studies in marine vertebrates (including fish), and maximum sizes and reproduction in invertebrates.
