Resource Assessment Report Temperate Demersal Elasmobranch Resource Of Western Australia, Matias Braccini, Nick Blay, S. A. Hesp, Brett Molony
Resource Assessment Report Temperate Demersal Elasmobranch Resource Of Western Australia, Matias Braccini, Nick Blay, S. A. Hesp, Brett Molony
Fisheries research reports
This document provides a cumulative description and assessment of the TDER and all of the fishing activities (i.e. fisheries / fishing sectors) affecting this resource in WA. Future Resource Assessment Reports will assess the Statewide Sharks and Rays Resource. The report is focused on the temperate indicator species (whiskery, gummy, dusky and sandbar sharks) used to assess the suites of demersal sharks and rays that comprise this resource. These species are primarily captured by demersal gillnets used in the TDGDLF that operate in the West Coast and South Coast Bioregions. For the North Coast bioregion, no commercial fishing for sharks …

Gulls, Martin S. Lowney, Scott F. Beckerman, Scott C. Barras, Thomas W. Seamans
Wildlife Damage Management Technical Series
Abundant gull (Figure 1) populations in North America have led to a variety of conflicts with people. Gulls cause damage at aquaculture facilities and other properties, and often collide with aircraft. Their use of structures on and near water results in excessive amounts of bird droppings on boats and docks. Their presence near outdoor dining establishments, swimming beaches, and recreational sites can lead to negative interactions with people. Large amounts of gull fecal material pollutes water and beaches resulting in drinking water contamination and swim bans. A combination of dispersal techniques, exclusion and limited lethal control may reduce damage to …
Detrital Protein Contributes To Oyster Nutrition And Growth In The Damariscotta Estuary, Maine, Usa, Cheyenne M. Adams
Detrital Protein Contributes To Oyster Nutrition And Growth In The Damariscotta Estuary, Maine, Usa, Cheyenne M. Adams
Electronic Theses and Dissertations
Oyster aquaculture is an expanding industry that relies on identifying and utilizing natural estuarine conditions for the economically viable production of a filter-feeding crop. The eastern oyster, Crassostrea virginica, is the principal species currently cultured in Maine. In addition to preferentially consumed phytoplankton, various detrital complexes (non-algal and/or non-living organic matter) may provide some nutrition to C. virginica between times of phytoplankton abundance. Here I investigated the importance of detrital proteins in supporting the growth of oysters cultured in the upper Damariscotta Estuary. Oyster aquaculture in this area is highly successful and previous reports indicate that labile detrital protein …
Changes In Hatchery Subsidies Of Chinook Salmon In The Salish Sea: Implications For Predators, Fisheries, And Conservation, Benjamin Nelson, Eric John Ward, Ole Shelton, Joseph H. Anderson
Changes In Hatchery Subsidies Of Chinook Salmon In The Salish Sea: Implications For Predators, Fisheries, And Conservation, Benjamin Nelson, Eric John Ward, Ole Shelton, Joseph H. Anderson
Salish Sea Ecosystem Conference
Historically, salmon hatcheries were designed to increase fishery production and to recover depleted native populations. As demands of human protein consumption increase and wild populations continue to decline due to anthropogenic impacts like climate change and habitat loss, hatcheries and stocking programs will be called on to provide food security and to supplement threatened populations. Since 1950 over 3.7 billion Chinook salmon have been released into the Salish Sea and its tributaries in Washington State and southern British Columbia. However, relatively little research has been conducted that considers the impact of hatchery subsidies on estuarine and nearshore marine ecosystems in …
The Jelly Team: Citizen Science At A Small Community Aquarium, Katy Kachmarik, Bri Gabel, Matt Wilson, Jessica Lotz, Elise Pletcher, Vanessa Hunt, Rus Higley
The Jelly Team: Citizen Science At A Small Community Aquarium, Katy Kachmarik, Bri Gabel, Matt Wilson, Jessica Lotz, Elise Pletcher, Vanessa Hunt, Rus Higley
Salish Sea Ecosystem Conference
The efforts and successes of a community volunteer group, ‘The Jelly Team’, exemplify citizen science achievement at the Marine Science and Technology Center, the marine biology and aquarium facility of Highline College in Des Moines, Washington. With little professional direction or funding, these volunteers have succeeded in culturing Moon Jellies to provide an ongoing display in the public aquarium, and are now expanding their activities to culturing other species and looking to provide specimens to local schools. A popular display at the MaST public aquarium is a kreisel tank featuring Aurelia labiata, the Pacific coast species of the Moon Jelly. …
Coastal Ocean Dynamics And Primary Productivity Near Traditional Indigenous Clam Gardens In Fulford Harbour, Salt Spring Island, British Columbia, Fred Burgess
Salish Sea Ecosystem Conference
Along the Pacific coasts of British Columbia and Alaska, it has recently come back into knowledge that Indigenous communities traditionally built and maintained clam gardens in the intertidal zone by clearing rocks, aerating sediments, and/or building rock walls. Since 2014, Parks Canada has been working with First Nations advisors of the W̱SÁNEĆ and Hul'qumi'num Treaty Groups in the Gulf Islands National Parks Reserve on the restoration of two ancient clam gardens in the Fulford Harbour area, Salt Spring Island, British Columbia. Royal Roads University is a partner in this restoration project, and as part of the partnership this research involves …
Toxicity Testing Of Atlantic Salmon Aquaculture Chemotherapeutants On Spot Prawns And Benthic Invertebrates, Steven B. Barrett, Tooba Khan, Chris J. Kennedy
Toxicity Testing Of Atlantic Salmon Aquaculture Chemotherapeutants On Spot Prawns And Benthic Invertebrates, Steven B. Barrett, Tooba Khan, Chris J. Kennedy
Salish Sea Ecosystem Conference
Demand for protein sources is high in North America and growing throughout the world. Global declines in fisheries has encouraged coastal regions to embrace aquaculture as a means of reconciling the growing pressures on wild fish stocks with this demand. Intensive salmon farming practices result in periodic infestations with naturally-occurring parasitic copepods referred to as “sea lice”. To prevent productivity losses, a variety of chemical and physical treatments have been implemented through regulatory systems or emergency applications. One objective of this study is to determine if these chemo-therapeutic treatments pose a risk to other non-target marine organisms including crustaceans such …
Population Genetics Of Native Shellfish Aquaculture Species And Potential Genetic Risks Of Cultivation, Natalie Lowell, Lorenz Hauser, Brent Vadopalas
Population Genetics Of Native Shellfish Aquaculture Species And Potential Genetic Risks Of Cultivation, Natalie Lowell, Lorenz Hauser, Brent Vadopalas
Salish Sea Ecosystem Conference
Native shellfish aquaculture has many benefits, but interbreeding of hatchery and wild populations may pose genetic risks to wild populations. The type and magnitude of these risks depends in part on the genetic population structure of native shellfish species. Early genetic studies on marine shellfish provided little evidence for such structure. However, recent population genetic studies provide higher resolution, make use of both neutral and non-neutral molecular markers, and suggest some marine shellfish can exhibit population structure and even local adaptation. Here, we present preliminary results on genetic differentiation among populations of Crassadoma gigantea (the purple-hinged rock scallop) and Parastichopus …
Salmon Farms: Are We Making Progress, Alexandra Morton
Salmon Farms: Are We Making Progress, Alexandra Morton
Salish Sea Ecosystem Conference
Commercial finfish aquaculture has endured a turbulent thirty years since its arrival in British Columbia. The international record on the state of wild salmonid populations exposed to salmon farms is not encouraging as there is no region where salmon farming and stable wild salmonid populations coexist. The industry has made changes as it matures, reporting better siting, sea lice control and vaccines. However at the same time the number of fish per farm has risen to 1.7 million, adjacent commercial fisheries are largely closed, orca are increasing failing to carry offspring full term and First Nations are without food fish. …
