Turner A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy University of Washington 2015 Reading Committee: Kenneth P. Sebens, Chair Megan N. Dethier Daniel E. Schindler Program Authorized to Offer Degree: Biology ii University of Washington Abstract Effects of fish predation on benthic communities in the San Juan Archipelago Kevin R. Turner Chair of the Supervisory Committee: Professor Kenneth P. Sebens Department of Biology Predation is a strong driver of community assembly, particularly in marine systems. Rockfish and other large fishes are the dominant predators in the rocky subtidal habitats of the San Juan Archipelago in NW Washington State. Here I examine the consumptive effects of these predatory fishes, beginning with a study of rockfish diet, and following with tests of the direct influence of predation on prey species and the indirect influence on other community members. In the first chapter I conducted a study of the diet of copper rockfish. Food web models benefit from recent and local data, and in this study I compared my findings with historic diet data from the Salish Sea and other localities along the US West Coast. Additionally, non-lethal methods of diet sampling are necessary to protect depleted rockfish populations, and I successfully used gastric lavage to sample these fish. Copper rockfish from this study fed primarily on shrimp and other demersal crustaceans, and teleosts made up a very small portion of their diet. Compared to previous studies, I found much higher consumption of shrimp and much iii lower consumption of teleosts, a difference that is likely due in part to geographic or temporal differences in prey availability.

Encrusting individuals were mostly small (84%); medium-sized specimens accounted for 11% and large for 5%. On the cephalothorax, most were observed in branchial (661) and orbital areas (240).

  • Urchin Rocks-NW Island Transect Study 2020
    The Long-term Effect of Trampling on Rocky Intertidal Zone Communities: A Comparison of Urchin Rocks and Northwest Island, WA. A Class Project for BIOL 475, Marine Invertebrates Rosario Beach Marine Laboratory, summer 2020 Dr. David Cowles and Class 1 ABSTRACT In the summer of 2020 the Rosario Beach Marine Laboratory Marine Invertebrates class studied the intertidal community of Urchin Rocks (UR), part of Deception Pass State Park. The intertidal zone at Urchin Rocks is mainly bedrock, is easily reached, and is a very popular place for visitors to enjoy seeing the intertidal life. Visits to the Location have become so intense that Deception Pass State Park has established a walking trail and docent guides in the area in order to minimize trampling of the marine life while still allowing visitors. No documentation exists for the state of the marine community before visits became common, but an analogous Location with similar substrate exists just offshore on Northwest Island (NWI). Using a belt transect divided into 1 m2 quadrats, the class quantified the algae, barnacle, and other invertebrate components of the communities at the two locations and compared them. Algal cover at both sites increased at lower tide levels but while the cover consisted of macroalgae at NWI, at Urchin Rocks the lower intertidal algae were dominated by diatom mats instead. Barnacles were abundant at both sites but at Urchin Rocks they were even more abundant but mostly of the smallest size classes. Small barnacles were especially abundant at Urchin Rocks near where the walking trail crosses the transect. Barnacles may be benefitting from areas cleared of macroalgae by trampling but in turn not be able to grow to large size at Urchin Rocks.

    DISTRIBUTION, ABUNDANCE, AND DIVERSITY OF EPIFAUNAL BENTHIC ORGANISMS IN ALITAK AND UGAK BAYS, KODIAK ISLAND, ALASKA by Howard M. Feder and Stephen C. Jewett Institute of Marine Science University of Alaska Fairbanks, Alaska 99701 Final Report Outer Continental Shelf Environmental Assessment Program Research Unit 517 October 1977 279 We thank the following for assistance during this study: the crew of the MV Big Valley; Pete Jackson and James Blackburn of the Alaska Department of Fish and Game, Kodiak, for their assistance in a cooperative benthic trawl study; and University of Alaska Institute of Marine Science personnel Rosemary Hobson for assistance in data processing, Max Hoberg for shipboard assistance, and Nora Foster for taxonomic assistance. This study was funded by the Bureau of Land Management, Department of the Interior, through an interagency agreement with the National Oceanic and Atmospheric Administration, Department of Commerce, as part of the Alaska Outer Continental Shelf Environment Assessment Program (OCSEAP). SUMMARY OF OBJECTIVES, CONCLUSIONS, AND IMPLICATIONS WITH RESPECT TO OCS OIL AND GAS DEVELOPMENT Little is known about the biology of the invertebrate components of the shallow, nearshore benthos of the bays of Kodiak Island, and yet these components may be the ones most significantly affected by the impact of oil derived from offshore petroleum operations. Baseline information on species composition is essential before industrial activities take place in waters adjacent to Kodiak Island. It was the intent of this investigation to collect information on the composition, distribution, and biology of the epifaunal invertebrate components of two bays of Kodiak Island. The specific objectives of this study were: 1) A qualitative inventory of dominant benthic invertebrate epifaunal species within two study sites (Alitak and Ugak bays).
