Predation and food limitation as causes of mortality in larval herring at a spawning ground in British Columbia

Creator:: Purcell, Jennifer E. and Grover, Jill J.
Abstract:: We quantified both in situ predation on Pacific herring (Clupea haregus pallasi ) larvae by soft-bodied zooplankton, and microzooplankton prey of herring larvae in Kulleet Bay, Vancouver Island, British Columbia. Samples were collected at 0 to 5 m depth daily at peak larval hatching from 14 to 21 April 1985....

Mass Abundances of Abnormal Pacific Herring Larvae at a Spawning Ground in British Columbia

Creator:: Purcell, Jennifer E., Grosse, Daniel, and Grover, Jill J.
Abstract:: Abnormalities including contortion of the body and reduction of the jaws and pectoral fins occurred among 2-25% of the yolk-sac Pacific herring larvae Clupea harengus pallasi collected in 1985 from Kulleet Bay, a spawning area on Vancouver Island, British Columbia. An additional 4-68% of the post-yolk-sac larvae had underdeveloped lower...

Predator and shelter-size effects on coral reef fish and spiny lobster prey

Creator:: Eggleston, David B., Lipcius, Romuald N., and Grover, Jill J.
Abstract:: Population dynamics of coral reef fishes and spiny lobster appear to be determined by variable recruitment interacting with post-settlement processes, particularly predation. The risk of predation may be modified by the scaling between prey and shelter size, which enhances the protective capacity of a reef. We experimentally tested these predictions...

Effects of the 1997-1998 El Niño on early-juvenile Pacific hake Merluccius productus: age, growth, abundance, and diet in coastal nursery habitats

Creator:: Grover, Jill J., Buckley, Troy W., and Woodbury, David
Abstract:: The effects of anomalous oceanographic conditions on growth, abundance, spawn-date distributions, and diet of early-juvenile Pacific hake Merluccius productus were examined in nursery grounds off the coast of central California, USA. Spring collections from 2 consecutive years of El Nino conditions, 1997 and 1998, 1 year of La Nina conditions,...

Long Term Trends and Sources of Sound in United States Waters

Creator:: Haver, Samara M.
Abstract:: Passive acoustic monitoring is a valuable tool for observing the status of marine environments. Comparisons of underwater soundscapes over temporal and spatial scales can provide data to inform marine conservation efforts, including protection of threatened and endangered species. This dissertation utilizes passive acoustic data collected via a broadly spaced array...

Evaluation of a Selective Flatfish Trawl and Diel Variation in Rockfish Catchability as Bycatch Reduction Tools in the Deepwater Complex Fishery off the U.S. West Coast

Creator:: Hannah, Robert W., Parker, Steven J., and Buell, Troy V.
Abstract:: We tested the potential of a selective flatfish trawl to reduce bycatch of slope rockfish in the upper continental slope bottom-trawl fishery (250–500 m) on the U.S. West Coast. The trawl we tested differed from typical slope trawls in that it was a low-rise, two-seam trawl with a severely cut...
