Actions To Implement And Complement The National System For The Prevention And Management Of Introduced Marine Pests In Western Australia, Fred E. Wells, Justin I. Mcdonald

Fisheries research reports

Introduced marine pests are regarded as one of the critical environmental issues worldwide which can damage the marine environment, including that of Western Australia. Most introduced species cause no apparent harm. A small minority of introduced species become pests, but these few can cause substantial economic and ecological damage.


Development Towards Commercialization Of Marine Fish Larvae Feeds – Microdiets: Final Frdc Report - Project 2004/258, Sagiv Kolkovski, John Curnow, Justin King Jun 2010

Development Towards Commercialization Of Marine Fish Larvae Feeds – Microdiets: Final Frdc Report - Project 2004/258, Sagiv Kolkovski, John Curnow, Justin King

Fisheries research reports

The project specifically focused on developing formulated diets for marine fish larvae, specifically targeting more physical aspects of microdiets such as feeding methods, feed availability and particle recognition. A commercially ready microdiet formulation was developed that achieved better ingestion, digestion and survival for yellowtail kingfish than other commercially available diets. Two manufacturers of aquaculture feeds showed interested in the formulations, however neither of the companies have started producing the diet commercially.


Virginia Shellfish Aquaculture Situation And Outlook Report : Results Of The 2009 Virginia Shellfish Aquaculture Crop Reporting Survey, Thomas J. Murray, Michael J. Oesterling Jun 2010

Virginia Shellfish Aquaculture Situation And Outlook Report : Results Of The 2009 Virginia Shellfish Aquaculture Crop Reporting Survey, Thomas J. Murray, Michael J. Oesterling

Reports

Virginia’s shellfish aquaculture industry continues to add significant value to the State’s seafood marketplace. While Virginia’s watermen harvest hard clams and oysters from the State’s public resources, they also grow shellfish for consumers. In recent years, following the lead of the hard clam industry, there has been a significant transition toward intensive aquaculture of native oysters. The once-extensive oyster planting has disappeared primarily as a result of endemic oyster diseases and wildlife predation of seed oysters. It has been replaced by an expanding aquaculture sector, which is based on improved culture techniques and disease-resistant oyster seed. While these trends are …

Annual Report - 2009 Data Collection And Analysis In Support Of Single And Multispecies Stock Assessments In Chesapeake Bay: The Chesapeake Bay Multispecies Monitoring And Assessment Program, Christopher F. Bonzek, James Gartland, Raemarie A. Johnson, Robert J. Latour

Reports

Historically, fisheries management has been based on the results of single-species stock assessment models that focus on the interplay between exploitation level and sustainability. There currently exists a suite of standard and accepted analytical frameworks (e.g., virtual population analysis (VPA), biomass dynamic production modeling, delay difference models, etc.) for assessing the stocks, projecting future stock size, evaluating recovery schedules and rebuilding strategies for overfished stocks, setting allowable catches, and estimating fishing mortality or exploitation rates. A variety of methods also exist to integrate the biological system and the fisheries resource system, thereby enabling the evaluation of alternative management strategies on …

Effects Of Variable Oceanographic Conditions On Forage Fish Lipid Content And Fatty Acid Composition In The Northern California Current, Marisa N. C. Litz, Richard D. Brodeur, Robert L. Emmett, Selina S. Heppell, Rosalee S. Hellberg, Linda O'Higgins, Matthew S. Morris

Food Science Faculty Articles and Research

Lipids and fatty acids (FA) were investigated in 4 species of forage fish: northern anchovy Engraulis mordax, Pacific sardine Sardinops sagax, Pacific herring Clupea pallasi, and whitebait smelt Allosmerus elongatus, for their ability to serve as biological indicators of ocean conditions in the California Current large marine ecosystem (CCLME). Samples were collected during the oceanographically contrasting years of 2005 and 2006. Upwelling was severely curtailed in the spring and early summer of 2005, leading to delayed biological productivity, whereas upwelling was relatively normal in spring 2006. Principal components analysis described 78% of the variance within the …

Mangrove species are uniquely adapted to tropical and subtropical coasts, and although relatively low in number of species, mangrove forests provide at least US $1.6 billion each year in ecosystem services and support coastal livelihoods worldwide. Globally, mangrove areas are declining rapidly as they are cleared for coastal development and aquaculture and logged for timber and fuel production. Little is known about the effects of mangrove area loss on individual mangrove species and local or regional populations. To address this gap, species-specific information on global distribution, population status, life history traits, and major threats were compiled for each of the …

Multi-Host Model-Based Identification Of Armillifer Agkistrodontis (Pentastomida), A New Zoonotic Parasite From China, Shao-Hong Chen, Qin Liu, Yong-Nian Zhang, Jia-Xu Chen, Hao Li, Ying Chen, Peter Steinmann, Xiao-Nong Zhou

Harold W. Manter Laboratory: Library Materials

Background: Pentastomiasis is a rare parasitic infection of humans. Pentastomids are dioecious obligate parasites requiring multiple hosts to complete their life cycle. Despite their worm-like appearance, they are commonly placed into a separate sub-class of the subphylum Crustacea, phylum Arthropoda. However, their systematic position is not uncontested and historically, they have been considered as a separate phylum.

Methodology/Principal Findings: An appraisal of Armillifer agkistrodontis was performed in terms of morphology and genetic identification after its lifecycle had been established in a multi-host model, that is, mice and rats as intermediate hosts, and snakes (Agkistrodon acutus and Python molurus) …

Shark Bay Prawn And Scallop Fisheries: Final Review Report, Western Australia. Department Of Fisheries Apr 2010

Shark Bay Prawn And Scallop Fisheries: Final Review Report, Western Australia. Department Of Fisheries

Fisheries management papers

The Shark Bay Prawn Fishery and Shark Bay Scallop Fishery operate in the same general areas of Shark Bay (although there are some differences in their areas of operation). The interrelationship between trawling activities for the two target species (prawns and scallops) has raised both management challenges and industry conflicts over time. Harvest level settings for each fishery (in the form of effort levels and the timing and/or location of fishing) are independently set, on the basis of recruitment and abundance surveys of each target species. However, each industry sector strongly believes that the interactions between the fisheries arise because …

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2009 Annual Report, John E. Olney, Brian Watkins, Eric J. Hilton Mar 2010

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2009 Annual Report, John E. Olney, Brian Watkins, Eric J. Hilton

Reports

Concern about the decline in landings of American shad (Alosa sapidissima) along the Atlantic coast prompted the development of an interstate fisheries management plan (FMP) under the auspices of the Atlantic States Marine Fisheries Management Program (ASMFC 1999). Legislation enables imposition of federal sanctions on fishing in those states that fail to comply with the FMP. To be in compliance, coastal states are required to implement and maintain fishery-dependent and fishery-independent monitoring programs as specified by the FMP. For Virginia, these requirements include spawning stock assessments, the collection of biological data on the spawning run (e.g., age-structure, sex ratio, and …

Reports

Concerns regarding the status of fishery-independent data collection from continental shelf waters between Cape Hatteras, North Carolina and the U.S. / Canadian border led the Atlantic States Marine Fisheries Commission’s (ASMFC) Management and Science Committee (MSC) to draft a resolution in 1997 calling for the formation of the Northeast Area Monitoring and Assessment Program (NEAMAP) (ASMFC 2002). NEAMAP is a cooperative state-federal program modeled after the Southeast Area Monitoring and Assessment Program (SEAMAP), which has been coordinating fishery-independent data collection south of Cape Hatteras since the mid-1980s (Rester 2001). The four main goals of this new program directly address the …

The Efficacy Of Sanctuary Areas For The Management Of Fish Stocks And Biodiversity In Wa Waters, James W. Penn, Warrick J. Fletcher Feb 2010

The Efficacy Of Sanctuary Areas For The Management Of Fish Stocks And Biodiversity In Wa Waters, James W. Penn, Warrick J. Fletcher

Fisheries research reports

Debate concerning the relative benefits of marine protected areas (MPAs) for the management of marine resources can often reflect unrecognized differences in the scope, scale and definitions of the objectives being sought by various Government or community bodies. There can also be different opinions on the level of protection required for an area to be considered an ‘MPA’ and functional definitions for both the biological diversity and ecosystems within these areas are often lacking. This paper seeks to outline the relative efficiency and effectiveness of MPAs, especially no-take sanctuary areas, compared to other strategies currently employed to help achieve the …

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Relatively few evaluations of aquatic macroinvertebrate and fish communities have been published in peer-reviewed literature detailing the effect of varying residual basal area (RBA) after timber harvesting in riparian buffers. Our analysis investigated the effects of partial harvesting within riparian buffers on aquatic macroinvertebrate and fish communities in small streams from two experiments in northern Minnesota northern hardwood-aspen forests. Each experiment evaluated partial harvesting within riparian buffers. In both experiments, benthic macroinvertebrates and fish were collected 1 year prior to harvest and in each of 3 years after harvest. We observed interannual variation for the macroinvertebrate abundance, diversity and taxon …
