The Vims Trawl Survey : Juvenile Atlantic Croaker, Brenda L. Norcross, Ginny H. Shaw

Reports

An index of juvenile croaker recruitment was developed to test proposed relationships between juveniles and environmental factors. The VIMS trawl survey data base is unique on the east coast because of its duration and continuity. No other data set exists that samples the same species in the same locality with concurrent physical data over a long period of time.

A Checklist Of Parasites Of California, Oregon, And Washington Marine And Estuarine Fishes, Milton S. Love, Mike Moser

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

This report is a summary of the published records of parasites found from the marine and estuarine fishes of California, Oregon, and Washington. Coverage has not been limited to the western United States, but rather includes parasite reports from throughout each fish's range. Included is a host-parasite list and parasite-host cross index.

We have produced this survey because we felt there was a need for a single source which would list all the parasites infecting marine and estuarine fish from California, Oregon, and Washington. Pertinent sources are scattered over a number of journals, covering many years. Workers find it time …

The Density Of Oysters And Shell Upriver From The Campostella Bridge In The Elizabeth River, Dexter S. Haven, James P. Whitcomb

Reports

This study estimates the density of oysters and oyster shells on that portion of the J. H. Miles Co. lease which lies within 450 feet of the upriver edge of the Campostella Bridge.

The Campostella Bridge is located on Route 460 on the Eastern Branch of the Elizabeth River (Figure 1). The area is restricted for shellfish culture by the Virginia State Health Department and salinities are high enough to favor the development of the oyster diseases Haplosporidium costalis (MSX) and Perkinsus marinum (Dermo). Because a combination of the effects of pollution and disease, the area has not produced commercial …

The Induction Of Tolerance To Heavy Metals In Natural And Laboratory Populations Of Fish, Wesley J. Birge, William H. Benson, Jeffrey A. Black

KWRRI Research Reports

Aquatic toxicity studies were performed on two natural populations of fathead minnows. One group of organisms was taken from a metal-contaminated flyash pond associated with a coal-fired power plant and the other group was collected from relatively uncontaminated hatchery ponds. Acute tests indicated that flyash pond fish were significantly more tolerant to cadmium and copper than were hatchery fish. At an exposure concentration of 6.0 mg Cd/L in moderately hard water, the median period of survival for flyash pond fish was 50.0 hr compared to 6.8 hr for hatchery fish. Both groups of organisms were about equally sensitive to zinc. …

Chronology Of Appearance & Habitat Partitioning By Stream Larval Fishes, Keith Floyd

Masters Theses & Specialist Projects

Larval fish were studied on the Middle Fork of Drake's Creek from 18 March 1982 to 9 September 1982. A total of 6,057 individuals representing 28 species and six unidentified cyprinids was collected. Micropterus sp. was the dominant species representing 33% of the total. Most of the remaining taxa were,generally,equally represented. Juvenile banded sculpins were the first larvae observed -- followed by darters, suckers, minnows, and sunfishes. The percid species, logperch, greenside darter, and Etheostoma (Ulocentra), illustrated the longest spawning periods, their larvae being taken from 24 March to 8 July. Maximum species occurrence was observed from 7 July …

Aquaculture--Now, Factory Fish Farming, Michael W. Fox

Aquaculture Collection

"Aquaculture 1983" was the title of a 5-day symposium and industry exhibit held in Washington, D.C., on january 9- 13,1983, sponsored by World Mariculture Society, Catfish Farmers of America, Fish Culture Section of the American Fisheries Society, U.S. Trout Farmers Association, Shellfish Institute of North America, and National Shellfisheries Association. While ecologists, economists, futurologists, and others have touted the virtues and potentials of intensive fish and shellfish farm- · ing, this growing industry in the U.S. may become blighted by the same problems that have come to afflict agribusiness' "factory farming" of crops, livestock, and poultry.

The Effects Of Limited Food Availability On The Striped Bass Fishery In Lake Mead, John R. Baker, Larry J. Paulson

Publications (WR)

The original range of striped bass (Morone saxatilis) was along the Atlantic Coast. They were introduced into the lower Sacramento River in 1879 and are now also found along the Pacific Coast. A landlocked striped bass fishery was established in Santee-Cooper Reservoir, South Carolina, in 1954, and they have since been introduced into numerous other reservoirs, including Lake Havasu, Lake Mead and Lake Powell on the Colorado River. Striped bass were introduced into Lake Mead in 1969 in response to declines in the largemouth bass (Micropterus salmoides) fishery that occurred during the 1960s and in order to further utilize the …

Historical Patterns Of Phytoplankton Productivity In Lake Mead, Richard T. Prentki, Larry J. Paulson

Publications (WR)

Lake Mead was impounded in 1935 by the construction of Hoover Dam. The Colorado River was unregulated prior to then and therefore was subjected to extreme variations in flows and suspended sediment loads. Hoover Dam stabilized flows and reduced suspended sediment loads downstream, but Lake Mead still received silt-laden inflows from the upper Colorado River Basin. The Colorado River contributed 97% of the suspended sediment inputs to Lake Mead, and up to 140 x 1O⁶ metric tons (t) entered the reservoir in years of high runoff. Most of the sediments were deposited in the river channel and formed an …

Growth And Activity Of Juvenile Mosquitofish: Temperature And Ration Effects, Wayne A. Wurtsbaugh, J. Cech

Watershed Sciences Faculty Publications

The effects of constant temperatures (10, 15, 20, 25, 30, and 35 C) and ration size on the growth rates and activity of juvenile mosquitofish Gambusia affinis (mean wet weight, about 20 mg) were measured in laboratory experiments. On ad libitum rations of Tubifex spp. worms, food-consumption rates of mosquitofish were very high, ranging from 7% dry body weight/day at 10 C to 83%/day at 35 C. Growth increased from 0% dry body weight/day at 10 C to 21%/day at 30 C and declined slightly at 35 C. Gross efficiencies (100 growth/food consumption) increased from 0 at 10 C to …

Infectious Pancreatic Necrosis (Ipn) Of Salmonid Fishes, Phillip E, Mcallister

United States Fish and Wildlife: Staff Publications

Infectious pancreatic necrosis (IPN) is a viral disease principally associated with salmonids, although IPN and lPN-like viruses have been isolated from various nonsa1rnonid fish and marine invertebrates. Acute infection occurs in 1- to 4-month-old salmonids and can result in cumulative mortality approaching 100%. In contrast, fish 6 months o~d or older can undergo subclinical or inapparent infection, but experience no significant mortality. Survivors of the disease can become lifelong carriers of the virus. Epizootics of IPN have been reported worldwide, and several virus serotypes are recognized.

The disease known as IPN was probably first described by M'Gonigle (1941) as acute …

Furunculosis And Other Diseases Caused By Aeromonas Salmonicida, G. L. Bullock, R. C. Cipriano, S. F. Snieszko

United States Fish and Wildlife: Staff Publications

Aeromonas salmonicida is a gram-negative bacterium that usually produces a water-soluble brown pigment. It was first described by Emmerich and Weibel (1890) as the cause of salmonid furunculosis in Germany. Although the disease was first considered to be limited to salmonids, studies by the Furunculosis Committee (Mackie et al. 1930, 1933, 1935) showed that A. salmonicida also infected other fish species. Present indications are that A. salmonicida or its variants also produce other diseases, such as ulcerative disease of goldfish (Carassius auratus), erythrodermatitis of common carp (Cyprinus carpio), ulcer disease of trout, and systemic infections among …

Chemical Induction Of Spawning By Serotonin In The Ocean Quahog Arctica Islandica (Linne), M. C. Gibbons, J. G. Goodsell, M. Castagna, R. Lutz

VIMS Articles

Serotonin injected into the anterior adductor muscle induced spawning in the ocean quahog Arcrica islandica (Linne) when using either individual or mass spawning techniques. This represents the fir st successful attempt to induce the release of gametes in this species which historically has been unresponsive to conventional spawning stimuli. The gametes released were competent and fertilization occurred without treating the encapsulated eggs with ammonium hydroxide or other chemicals. Larvae were reared through metamorphosis to early juvenile stage.

The Origin And Extent Of Oyster Reefs In The James River, Virginia, Dexter S. Haven, James P. Whitcomb

VIMS Articles

The public oyster grounds (Baylor Survey Grounds) in the James River, VA, were studied with respect to bottom type and oyster density from 1978 to 1981. Approximately 10,118 ha (25,000 acres) were investigated using an electronic positioning system to establish station locations. Bottom types were determined using probing pipes, patent tongs, and an acoustical device. About 17.1% of the bottom was classified as consolidated oyster reef, and 47.5% was moderately productive mud-shell or sand-shell bottoms. The remaining 35.4% was rated as unsuitable for oyster culture. The surface configuration of oyster reef areas in the James River is similar to those …
