Restoring Wildlife Habitat On Rat Island: Environmental Assessment

United States Fish and Wildlife: Staff 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

United States Fish and Wildlife: Staff 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 of …

Developmental Reproductive Effects Of Exposure To Pharmaceutical Steroids In The Aquatic Environment: Studies On Mosquitofish (Gambusia Affinis Affinis),Roach (Rutilus Rutilus) And Medaka(Oryzias Latipes), Taisen Iguchi, Yoshinao Katsu, Hiroshi Urushitani, Anke Lange, Charles R. Tyler

Journal of Marine Science and Technology

Pharmaceutical androgens and estrogens discharged into the aquatic environment are now known to induce adverse effects in fish and are a health concern for wildlife. Mosquitofish (Gambusia affinis) exposed to a pharmaceutical androgen, trenbolone, used to enhance cattle growth and found to pollute waters below feedlots in the USA, has been shown to alter the development of the anal fin of the females and disrupt gonopodium development in fry. In our work, we showed that altered gonopodium development was associated with disruption in the normal patterns of expression of 2 cloned androgen receptors. Furthermore, exposure to trenbolone at 1 µg/L …

Effects Of Elevated Seawater Co2 Concentration On The Meiofauna, Haruko Kurihara, Atsushi Ishimatsu, Yoshihisa Shirayama

Journal of Marine Science and Technology

An increase in atmospheric CO2 concentration leads to a rise in CO2 concentrations and a decrease in pH of the ocean surface water due to continuous gas exchange between air and seawater, which may have serious impacts on neritic marine organisms. In this study, we assessed the impacts of elevated CO2 concentrations on meiobenthic organisms by exposing them to seawater equilibrated with air (control: CO2 concentration 380 ppm) or CO2-enriched air (2,000 ppm higher than control, CO2 concentration predicted by the year 2300) for 56 days in microcosms. We observed no significant differences in the abundance of total meiofauna, nematodes, …

Adaptation To Deep-Sea Hydrothermal Vents: Some Molecular And Developmental Aspects, Florence Pradillon, Françoise Gaill

Journal of Marine Science and Technology

Alvinella pompejana is a polychaetous annelid inhabiting the surface of deep sea hydrothermal chimneys along the ridge of the east part of the Pacific ocean. The main characteristic of this emblematic species is its habitat, which is very aggressive considering its temperature. The exceptional thermotolerance of this species (up to 80°C) has been the subject of much controversy. This review is focused on the thermal adaptation of this worm regarding molecular data relative to its extracellular matrix and life history traits.

Neuroendocrinology Of Fish Metamorphosis And Puberty: Evolutionary And Ecophysiological Perspectives, Sylvie Dufour, Karine Rousseau

Journal of Marine Science and Technology

Metamorphosis and puberty are two major events of the postembryonic development in Vertebrates. Based on some examples from fish species, we review the definition, role and regulation of these events, analyze their common and different features, as well as their impact on the evolution and diversity of life cycles. The term of puberty, firstly defined in humans, has been subsequently extended to the first acquisition of the capacity to reproduce in all mammalian and non-mammalian vertebrates as well as in invertebrates. By definition, puberty occurs only once in the life cycle. However, some similarities may be found with other events, …

Simulated Migration Of European Silver Eel; Swim Capacity And Cost Of Transport, Guido Van Den Thillart, Arjan Palstra, Vincent Van Ginneken

Journal of Marine Science and Technology

An important aspect of the reproduction of European silver eels is the huge distance (ca 6000-km) they have to swim to reach their spawning grounds. So, obviously endurance swimming is a major requirement for successful reproduction. As migrating eels don’t feed, two major questions should be asked: 1) what are the energy costs to cross the Atlantic Ocean, 2) How much fat do eels need to cover the expenses. From swim tunnel experiments run for days till even 6 months we could determine the cost of transport (COT): 0.5 kJ km-1 kg-1. This amount is about 5 times lower than …

Role Of Sex Hormones In Sex Change Of Grouper, Masaru Nakamura, Mohammad Ashraful Alam, Yasuhisa Kobayashi, Ramji Kumar Bhandari

Journal of Marine Science and Technology

Groupers are commercially important coral reef fishes because of their excellent flavor and high price. Due to their sex changing nature, commercial aquaculture operations have not yet been developed for groupers. Sex steroids play a critical role in the initiation of sex change, but their exact function and mechanism of action are unknown. We have investigated the role of sex steroids in protogynous sex change using the honeycomb grouper, Epinephelus merra, for a number of years. Our studies have shown that sex steroids play a major role in sex change. In this review, we integrate our findings to better understand …

This document was developed to promote protection of Alaska’ wildlife from nonnative rodents, especially rats. If constitutes a statewide invasive rodent management plan, which is part of a multi-agency effort to minimize the impact of invasive species in Alaska. A literature search and interviews were conducted, and reviews were obtained from experts in Alaska and elsewhere. The plan summarizes resisting information relevant to Alaska and recommends a collaborative structure for undertaking strategic actions, the Alaska Rodent Action Team. It also identifies dozens of strategic actions that are needed to prevent and eradicate invasive rodents. These fall into six categories: legal …

Limb Regeneration After Multiple Autotomy And Coxae Removal In The Blue Crab Callinectes Sapidus, Jennifer Ambler

OES Theses and Dissertations

This study investigated limb regeneration in the juvenile blue crab, Callinectes sapidus, specifically the role of the coxa and pedal nerve innervation of the regenerative limb bud over time. The coxa is a leg segment that has been defined as the source of positional, cellular, and neuronal information needed for limb regeneration in brachyuran crabs. This study indicates that removal of coxae under regenerative and non-regenerative conditions did not deter limb regeneration. The coxa is not the exclusive location of limb regenerative information since limbs re-grew with normal positional and functional arrangement in 86% of crabs showing regeneration at removal …

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 wind-driven …

Managing The Recreational Catch Of Demersal Scalefish On The West Coast. Future Management Scenarios For Community Consideration, Jon Ford (Minister For Fisheries; The Kimberley, Pilbara And Gascoyne)

Fisheries management papers

This paper discusses the major issues around controlling the total recreational catch. It also considers some of the tools available to manage the catch to specific target levels. The sustainability of fish species must be a key driver. However, the impacts on the social amenity of recreational fishing must also be taken into account. Any particular tool, if used on its own and to its full extent, may be rather “blunt” in its application and its impacts unacceptable to large parts of the community. The most effective and acceptable management package will probably be a mix of tools, supported by …

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, fish exposed …

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 these …

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 U.S …
