Pioneering Lobster Aquaculture In Rhode Island, Michael A. Rice Dec 2007

Pioneering Lobster Aquaculture In Rhode Island, Michael A. Rice

Michael A Rice

The 1898 establishment and operation of a lobster hatchery in Wickford Harbor under the auspices of the Rhode Island Commission on Inland Fisheries is reviewed. Dr. Herman Carey Bumpus a professor at Brown University and director of the United States Fisheries Commission undertook this effort to culture lobsters as a result of a decline in lobster landings, and concern for the stocks. Work at the hatchery led do considerable information about lobster reproductive and larval biology, and pioneering aquaculture methods for the species. By the mid-1920s, the hatchery was producing upwards of a million larvae per year and releasing them ...


Restoring Wildlife Habitat On Rat Island: Environmental Assessment Dec 2007

Restoring Wildlife Habitat On Rat Island: Environmental Assessment

US Fish & Wildlife Publications

Restoration of natural ecosystem function on Rat Island promises to re-establish native seabirds and other native species, thus returning this wilderness island to a healthy natural community. This restoration cannot occur until the island is cleared of the invasive non-native rats that now dominate the living community.

Introduced non-native species are a leading cause of extinctions in island communities worldwide. Increasingly, land managers are removing introduced species to aid in the restoration of native ecosystems. Rats are responsible for 40-60% of all recorded bird and reptile extinctions worldwide. Given their widespread successful colonization on islands and the resulting impact to ...

2006 National Survey Of Fishing, Hunting, And Wildlife-Associated Recreation

US Fish & Wildlife Publications

The National Survey of Fishing, Hunting, and Wildlife-Associated Recreation reports results from interviews with U.S. residents about their fishing, hunting, and wildlife watching. This report focuses on 2006 participation and expenditures of persons 16 years of age and older.

However, in addition to 2006 estimates, we also provide trend information in the Highlights section and Appendix C of the report. The 2006 numbers reported can be compared with those in the 1991, 1996, and 2001 Survey reports because they used similar methodologies. However, 2006 estimates should not be directly compared with results from Surveys conducted earlier than 1991 because ...

Evaluating Recruitment Of American Eel, Anguilla Rostrata, To The Potomac River (Spring 2007), Hank Brooks, Wendy A. Lowery, Aimee Halvorson, James Gartland, Marcel M. Montane

Reports

Harvests of American eel along the U.S. Atlantic Coast have declined in recent years, and similar patterns have been noted in the Canadian Maritime Provinces as well as in Europe with its congener, A. anguilla (Ciccotti et al., 4 1995). Fishery independent indices of abundance have also shown a decline in American eel populations in recent years (Richkus and Whalen, 1999; Geer, 2003; Montane and Fabrizio, 2006). Possible explanations for this decline include Gulf Stream shifts, pollution, overfishing, parasites, and barriers to fish passage (Castonguay et al., 1994; Haro et al., 2000). In addition, local factors such as unfavorable ...

Assessment Of The Flame Angelfish (Centropyge Loriculus) As A Model Species In Studies On Egg And Larval Quality In Marine Fishes, Chatham K. Callan Aug 2007

Assessment Of The Flame Angelfish (Centropyge Loriculus) As A Model Species In Studies On Egg And Larval Quality In Marine Fishes, Chatham K. Callan

Electronic Theses and Dissertations

This project sought to determine if flame angelfish (Centropyge loriculus) could serve as models in examination of environmental and dietary effects on egg quality in marine fishes. Evaluation of 21 marine ornamental species identified flame angelfish as being amenable to egg quality research, due to their rapid conditioning and frequency of spawning. At the onset of this project, accidental copper introduction to broodstock systems required assays to determine the effects of copper exposure on survival and reproduction. Flame angelfish exhibited accute sensitivity to copper, as 60% of fish exposed to 0.25mg/L died within 12 hours of exposure. Likewise ...


Shallow Water Fish Communities And Coastal Development Stressors In The Lynnhaven River, Donna M. Bilkovic, David Stanhope, Kory Angstadt Aug 2007

Shallow Water Fish Communities And Coastal Development Stressors In The Lynnhaven River, Donna M. Bilkovic, David Stanhope, Kory Angstadt

Reports

Coastal development pressures in the Mid-Atlantic have been attributed to significant negative impacts to aquatic ecosystems. The Lynnhaven River watershed, located in the southernmost extent of the Chesapeake Bay and encompassing Virginia Beach, is an example of a shallow-water tidal system under intense development pressure that is confronted with multiple and often conflicting coastal management issues. Rapid development in and around the City of Virginia Beach over the past few decades has led to the loss of natural buffers and habitat (e.g. oyster, wetlands and seagrasses), increased sedimentation, and degraded water quality. The Lynnhaven Ecosystem Restoration Project, led by ...

Estimating Relative Abundance Of Young-Of-The-Year American Eel Anguilla Rostrata In The Virginia Tributaries Of Chesapeake Bay (Spring 2006), Marcel M. Montane, Wendy A. Lowery, Hank Brooks, Aimee D. Halvorson

Reports

The Atlantic States Marine Fisheries Commission (ASMFC) adopted the Interstate Fishery Management Plan (hereafter referred to as FMP) for the American eel in November 1999. The FMP focuses on increasing coastal states’ efforts to collect American eel data through both fishery dependent and fishery independent studies. Consequently, member jurisdictions (including Virginia) agreed to implement an annual survey for YOY American eels. The survey is intended to “…characterize trends in annual recruitment of the YOY eels over time [to produce a] qualitative appraisal of the annual recruitment of American eel to the U.S. Atlantic Coast” (ASMFC, 2000). The development of ...

Sampling A Littoral Fish Assemblage: Comparison Of Small-Mesh Fyke Netting And Boat Electrofishing, Carl R. Ruetz Iii, Donald G. Uzarski, Damon M. Krueger, Edward S. Rutherford Jul 2007

Sampling A Littoral Fish Assemblage: Comparison Of Small-Mesh Fyke Netting And Boat Electrofishing, Carl R. Ruetz Iii, Donald G. Uzarski, Damon M. Krueger, Edward S. Rutherford

Peer-reviewed scientific publications

We compared small-mesh (4-mm) fyke netting and boat electrofishing for sampling a littoral fish assemblage in Muskegon Lake, Michigan. We hypothesized that fyke netting selects for small-bodied fishes and electrofishing selects for large-bodied fishes. Three sites were sampled during May (2004 and 2005), July (2005 only), and September (2004 and 2005). We found that the species composition of captured fish differed considerably between fyke netting and electrofishing based on nonmetric multidimensional scaling (NMDS). Species strongly associated with fyke netting (based on NMDS and relative abundance) included the brook silverside Labidesthes sicculus, banded killifish Fundulus diaphanus, round goby Neogobius melanostomus, mimic ...

Detection Of Panulirus Argus Virus 1 In Caribbean Spiny Lobsters, Megan M. Montgomery-Fullerton, Roland Cooper, Kathryn M. Kauffman, Jeffrey D. Shields, Robert E. Ratzlaff

Collected Faculty and Staff Scholarship

Panulirus argus Virus 1 (PaV1) is a pathogenic virus that infects Caribbean spiny lobsters P. argus in the Florida Keys. We have developed a PCR detection assay for PaV1 for the purpose of studying the natural history of the virus and for monitoring the prevalence of infection. The detection of the virus in hemolymph and other tissues is based on the PCR amplification of a 499 bp product using specific primers designed from a cloned fragment of the PaV1 genome. The sensitivity limit for the assay was 1.2 fg of purified viral DNA. The PaV1 primers did not react ...

Kurt A. Rosentrater

Extrusion trials were conducted with varying levels of DDGS along with soy flour, corn flour, fish meal, vitamin mix, mineral mix and net protein content adjusted to 28% in a Wenger TX-52 twin screw extruder. The properties of extrudates obtained with experiments conducted in full factorial design with 3 levels of DDGS content, 2 levels of moisture content and 2 levels of screw speed were studied. Increasing the DDGS content from 20% to 60%, resulted in 36.7% decrease in the radial expansion leading to 159%, 61.4% increase in the unit density and bulk density of the extrudates. Increasing ...

The goal of this study was to investigate the effect of die nozzle dimensions, barrel temperature profile, and moisture content on DDGS-based extrudate properties and extruder processing parameters. An ingredient blend containing 40% distillers dried grains with solubles (DDGS), along with soy flour, corn flour, fish meal, whey, mineral and vitamin mix, with a net protein content adjusted to 28% was extruded in a single-screw laboratory extruder using seven different die nozzles. Increasing moisture content of the ingredient mix from 15 to 25% resulted in a 2.0, 16.0, 16.3, 22.9, 18.5, 32.5, and 63 ...


Virginia Shellfish Aquaculture Situation And Outlook Report : Results Of The 2005-2007 Virginia Shellfish Aquaculture Crop Reporting Survey, Thomas J. Murray, Michael J. Oesterling Jun 2007

Virginia Shellfish Aquaculture Situation And Outlook Report : Results Of The 2005-2007 Virginia Shellfish Aquaculture Crop Reporting Survey, Thomas J. Murray, Michael J. Oesterling

Reports

Continued growth of the shellfish aquaculture industry in Virginia has added significant value to the state’s seafood marketplace. Today, watermen continue to harvest both hard clams and oysters from the state’s public resources, albeit at diminished rates. At the same time, Virginia’s watermen-farmers are providing growing quantities of additional quality shellfish to consumers. Following the lead of the hard clam industry, there has been a significant transition to intensive aquaculture of native oysters in recent years. The once extensive oyster planting has disappeared primarily as a result of endemic oyster diseases and increasing wildlife predation of seed ...

Ecosystem Services Related To Oyster Restoration, Ld Coen, Rd Brumbaugh, D Bushek, R Grizzle, Mw Luckenbach, Et Al

VIMS Articles

The importance of restoring filter-feeders, such as the Eastern oyster Crassostrea virginica, to mitigate the effects of eutrophication (e.g. in Chesapeake Bay) is currently under debate. The argument that bivalve molluscs alone cannot control phytoplankton blooms and reduce hypoxia oversimplifies a more complex issue, namely that ecosystem engineering species make manifold contributions to ecosystem services. Although further discussion and research leading to a more complete understanding is required, oysters and other molluscs (e.g. mussels) in estuarine ecosystems provide services far beyond the mere top-down control of phytoplankton blooms, such as (1) seston filtration, (2) benthic–pelagic coupling, (3 ...

Annual Progress Report - 2006 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, Robert J. Latour, James Gartland

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 ...
