External Morphology Of The Chorion Of The Annual Fishes Cynolebias (Cyprinodontiformes: Rivulidae), Marcelo Loureiro, Rafael O. De Sá

Biology Faculty Publications

Members of the family Rivulidae (killifishes) inhabit temporary bodies of freshwater in South and Central America (one species is also found in North America). The most remarkable characteristic of the family Rivulidae is that species have an annual life cycle with a drought-resistant egg during the dry season. Parenti's (1981) analysis of the order Cyprinodontiformes considered a single genus, Cynolebias, whereas Cos- ta's (1990) phylogenetic analysis of the family Rivulidae separates Cynolebias from Cynopoecilus. One of Costa's synapomorphies to separate Cynopoecilus is the unique structure of their egg's chorion, which is shared with Leptolebias and Campellolebias.

Fishery Independent Standing Stock Surveys Of Oyster Populations In Virginia 1996, Roger L. Mann, James Wesson

Reports

Extensive description of the Virginia oyster resource and history of its utilization has been given by Haven, Hargis and Kendall (1981), and more recently reviewed by Hargis and Haven (1988). These contributions, among many others, describe a state of continuing decline. The James River, Virginia has served as the focal point for the Virginia oyster industry for over a century, being the source of the majority of seed oysters that were transplanted for grow-out to locations within the Virginia portion of the Chesapeake Bay and much further afield in the Middle Atlantic states (Haven et al, 1981 ). The Rappahannock …

Juvenile Fish And Blue Crab Stock Assessment Program Bottom Trawl Survey Annual Data Summary Report Volume 1995, Patrick J. Geer, Herbert M. Austin

Reports

The Virginia Institute of Marine Science (VIMS) has conducted a trawl survey dating back to 1955. Over the years methods and objectives have varied according to funding sources and state and/or federal mandates. The present thrust of the program is to provide juvenile indices of relative abundance for recreationally, commercially, and ecologically· important fish and invertebrates. These measures of juvenile abundance are widely used as a key element in the management of the Atlantic States' coastal fishery resources. Estimates of juveniles (age-0) have proven to be a reliable and early indicator of future year-class strength. A review of previously available …

Juvenile Finfish And Blue Crab Stock Assessment Program York River Random Stratified Bottom Trawl Survey Data Summary Report Volume R1989-1990, Michael F. Land, Patrick J. Geer, Christopher F. Bonzek, Herbert M. Austin

Reports

The Virginia Institute of Marine Science (VIMS) has conducted a bottom trawl survey of some fashion since 1955. Historically, sampling has occurred as mid-channel transects at fixed locations spaced at approximately five mile intervals. In the early 1970's, work was performed on the Mobjack Bay and Piankatank River using the standard 30 ft. fishing gear from a large research platform, with a 16 ft. gear towed from an outboard skiff or Chesapeake deadrise at shallow stations (:$; 12 ft.). Linda Pushee Mercer initiated the first random survey of the York River in 1971-72, as part of the results of a …

Estimation Of Relative Abundance Of Recreationally Important Finfish In The Virginia Portion Of The Chesapeake Bay : Annual Progress Report July 1995 - June 1996, Patrick J. Geer, Herbert M. Austin

Reports

Measures of juvenile abundance are presently in wide use as a key element in the management of the Atlantic States' coastal fishery resources. Estimates of the relative interannual abundance of early juveniles (age-0) generated from scientific survey programs have been found to provide a reliable and early estimator of future year class strength (Goodyear 1985, Lipcius and Van Engel 1990). After a review of previously available indices of juvenile abundance for important fishery resource species in the Chesapeake Bay, the Chesapeake Bay Stock Assessment Committee (CBSAC), a federal/state committee sponsored and funded by the National Oceanic and Atmospheric Administration (NOAA), …

Density-Dependent Settler-Recruit-Juvenile Relationships In Blue Crabs, Aj Pile, R Lipcius, J Van Montfrans, R J. Orth

VIMS Articles

Current theory on the population dynamics of marine species with complex life history patterns posits that a suite of physical and biotic forces (e.g., habitat structure and density-dependent predation or emigration) control survival and abundance in early life history, particularly after settlement. We have conducted a long-term sampling effort accompanied by a series of field and laboratory experiments examining the joint effects of habitat type, body size, and population density upon abundance and survival of early juveniles of the blue crab, Callinectes sapidus. In addition, the chance occurrence of a tropical storm during one set of experiments provided an opportunity …

Juvenile Finfish And Blue Crab Stock Assessment Program York River Random Stratified Bottom Trawl Survey Data Summary Report Volume R1991-1994, Micheal F. Land, Patrick J. Geer, Christopher F. Bonzek, Herbert M. Austin

Reports

The Virginia Institute of Marine Science (VIMS) has conducted a bottom trawl survey of some fashion since 1955. Historically, sampling has occurred as mid-channel transects at fixed locations spaced at approximately five mile intervals. During the 1970's, the need for a random stratified survey of the main stem Bay and tributaries was realized and subsequently implemented. This program had a very large spatial coverage in various depth strata, but was very limited in its temporal component. Sampling occurred on a semi-annual basis primarily in January and February, and again in July (Wojcik and Van Engel, 1988a.) Based on previous results …

Rare And Endangered Plants At Gateway National Recreation Area: A Case For Protection Of Urban Natural Areas, Richard Stalter, Michael D. Byer, John T. Tanacredi Ph.D.

Faculty Works: CERCOM

The diversity of native plant species in urban environments is usually overlooked when biodiversity levels are considered. Inventories of native plants reveal many to be rare species surviving the harsh conditions encountered in urban ecosystems. Knowledge of their existence and an inventory of their distribution will assist in maintaining these populations. Protection strategies for rare plant species are outlined for urban National Parks.

Histopathology Of The Thymus Of Coho Salmon Oncorhynchus Kisutch Experimentally Infected With Renibacterium Salmoninarum, E Flano, Sl Kaattari, B Razquin, Aj Villena

VIMS Articles

We report on the histopathological changes occurring in the thymus of coho salmon Oncorhynchus kisutch experimentally infected with Renibacterium salmoninarum. Coho salmon were intraperitoneally infected, and the thymi were collected weekly from 1 to 7 wk post-infection, and processed for ultrastructural study. The thymus appeared to be infected only in fish collected at 6 and 7 wk post-infection. The first stage of the infection was characterized by the presence of a low number of bacteria scattered in the connective tissue of the capsule. Further progression of the thymic infection was characterized by the rupture of the capsular-thymic barrier, and by …

Conference organizers and/or faculty included University of Colorado School of Law professors Betsy Rieke, David H. Getches, Michael A. Gheleta and Charles F. Wilkinson.

All across the country--in Congress, in state legislatures and in urban and rural communities--people are discussing why we should or should not protect biodiversity and how best to do so. Since the Endangered Species Act is up for reauthorization, a variety of reform proposals are being debated. Speakers--including natural resource scholars, experts from the private and nonprofit sectors, and government officials--will examine the rationale for biodiversity protection, the legal framework of the Endangered Species Act, and …

Irrigation, Power, And Salmon: The Case For Voluntary Water Transfers In The Columbia Basin, Eric Kuhner

Center for Urban Studies Publications and Reports

This paper begins with a brief history of water law in the west, illustrating the roots of conflict over water allocation. A more detailed examination of activities in the Columbia Basin follows, describing the many parties affected by issues of water use and the overlapping institutional structures that govern the river and its water.

Sources of pressure to change the current pattern of water use are then considered. These include requirements to protect endangered salmon runs and the change over time in the relative values of water for power production and irrigation. This section demonstrates how changes in the value …

Offshore Constitutional Settlement 1995, H. G. Brayford, G. E. Lyon

Fisheries management papers

The Offshore Constitutional Settlement OCS is a legal arrangement between the Commonwealth and State Governments, and defines control over the fisheries which operate off each State of Australia. For the Western Australian coast, the first set of arrangements took effect in 1987. The OCS of 1995 specifies five arrangements, under which the fisheries inside the 200 nautical mile approximately 370 km limit of the Australian Fishing Zone AFZ come under either State, Commonwealth, or joint control.
