Hepatic Microsomal N-Hydroxylation Of Aniline And 4-Chloroaniline By Rainbow Trout (Onchorhyncus Mykiss), Steven P. Bradbury, J. M. Dady, A. D. Hoffman, M. M. Voit, D. L. Olson
Hepatic Microsomal N-Hydroxylation Of Aniline And 4-Chloroaniline By Rainbow Trout (Onchorhyncus Mykiss), Steven P. Bradbury, J. M. Dady, A. D. Hoffman, M. M. Voit, D. L. Olson
Steven P. Bradbury
N-Hydroxylation of aniline and 4-chloroaniline was quantified in rainbow trout microsomal preparations using h.p.l.c.-liquid scintillation methods. Radioactive phenylhydroxylamine and 4-chlorophenylhydroxylamine metabolites were identified by co-elution with non-labelled standards. The method provided resolution of metabolite standards, and quantification of both N-hydroxylated metabolites was achieved without derivatization. The maximum velocities at 25 degrees C were 33.8 +/- 1.40 and 22.0 +/- 0.98 pmol/min per mg for aniline and 4-chloroaniline N-hydroxylation, respectively. The Km values were 1.0 +/- 0.11 and 0.8 +/- 0.11 mM for aniline and 4-chloroaniline N-hydroxylation, respectively. These activities were not induced by treatment of the trout with Aroclor 1254 …
Computer Simulation Techniques To Assess Bias And Precision In The Roving Creel Survey Estimator, David L. Wade
Computer Simulation Techniques To Assess Bias And Precision In The Roving Creel Survey Estimator, David L. Wade
Biological Sciences Theses & Dissertations
Fisheries scientists use roving creel survey methods to estimate total catch and total effort of recreational fisheries. Bias in the roving creel estimators had been known to the scientific community, but it had not been quantified. I developed a roving-creel-survey computer simulation model to investigate the bias and precision of roving creel estimators, and estimated parameters for the model based on field observations from the blue crab (Callinectes sapidus) fishery of the Chesapeake Bay. The computer model was used to identify bias in roving-creel effort and catch estimators and to demonstrate survey methods that will reduce this bias. …
Biodepuration Of Polynuclear Aromatic Hydrocarbons From A Bivalve Mollusk, Mercenaria Mercenaria L, John T. Tanacredi Ph.D., Raul R. Cardenas
Biodepuration Of Polynuclear Aromatic Hydrocarbons From A Bivalve Mollusk, Mercenaria Mercenaria L, John T. Tanacredi Ph.D., Raul R. Cardenas
Faculty Works: CERCOM
Mercenaria mercenaria, exposed in vitro for 48 h to nine parent polynuclear aromatic hydrocarbons (PAHs) found in waste crankcase oil (WCCO) and analysed by multiparametric analysis over a 45- day depuration period in an activated carbon filtration aquaria system, did not depurate PAHs, but rather maintained them at detectable levels. Uptake of PAHs was shown to be directly related to clam weight. A cluster analysis of empirical results reaffirmed a biostabilization in PAH groupings in clam tissue over a 45-day depuration period and exhibited no evidence of a decreasing trend in total PAHs when subjected to ANOVA. Due to the …

Is Rainbow Trout Condition Influenced By Invertebrate-Drift Density?, Randall B. Filbert
Is Rainbow Trout Condition Influenced By Invertebrate-Drift Density?, Randall B. Filbert
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Users of the Instream Flow Incremental Methodology CTFIM) commonly assume that there is a positive linear relationship between available habitat (WUA) and stream fish biomass. However, several studies have shown a lack cf correlation between WUA and biomass. Such poor relationships may occur if other factors limit fish abundance. Food availability is a potentially important factor limiting abundance of stream fishes and can affect blomass by influencing fish condition (individual weight). I collected rainbow trout (Oncorhynchus mykiss) exposed to different levels of invertebrate-drift density to determine if condition was greater where food was more abundant. I also examined …

Oyster Spatfall In Virginia Waters: 1990 Annual Summary, Bruce J. Barber
Oyster Spatfall In Virginia Waters: 1990 Annual Summary, Bruce J. Barber
Reports
The Virginia Institute of Marine Science (VIMS) conducts surveys ofoyster spatfall (or "setting") in Virginia waters throughout the summer reproductive period. This survey provides an estimate of the potential of a particular area for receiving a "strike" or set of oysters on the bottom and helps define the timing of setting events. Information obtained from this effort is valuable to the Virginia Marine Resources Commission (VMRC) for its shell repletion program, and to private oyster growers, both of which are interested in maximizing the timing of shell planting. In addition, by maintaining a long-term data base, trends in spatfall throughout …
The Economic Impact Of Recreational Fishing In Western Australia., R. K. Linchner
The Economic Impact Of Recreational Fishing In Western Australia., R. K. Linchner
Fisheries management papers
The Minister for Fisheries commissioned Economic Research Associates to carry out a study of the economic impact of recreational fishing in Western Australia. Two surveys were conducted to determine how much recreational fishers spend during the year on goods and services in order to go fishing. One involved telephone interviews of 401 recreational fishers, who were selected from a stratified random sample of households in five major regions of the state. The other survey employed a self enumeration questionnaire sent to randomly selected licensed recreational fishers, as well as being made available on non-random self-selection basis through fishing clubs and …
Prospects For Fisheries Development In West Africa, Steven K. Ireland
Prospects For Fisheries Development In West Africa, Steven K. Ireland
Theses and Major Papers
The production of food is a primary concern for the countries of Africa. Marine fisheries can contribute toward alleviating undernutrition and provide employment opportunities in developing countries. In West Africa there are substantial marine fisheries resources but there is a need for development and improved management of these resources. Fisheries development efforts have thus far achieved limited success in the region. However, there is considerable potential for increasing the contribution of fisheries to economic development if the problems of fisheries development can be overcome.
Striped Bass Management In Rhode Island, Thomas N. Fetherston Ii
Striped Bass Management In Rhode Island, Thomas N. Fetherston Ii
Theses and Major Papers
The management of highly migratory marine species is a difficult and complex task. No creature better represents the myriad problems faced by those attempting interstate fisheries management than the striped bass of the Atlantic coast. Their high stock levels in the late 1960s attracted unprecedented attention from commercial and sport fishermen alike. The dramatic crash of these stocks in the late 1970s, subsequent attempts at coastwide management, eventual Federal intervention and finally the rebound of the Atlantic striped bass population is an interesting case study. This paper will focus on what transpired in the State of Rhode Island during this …

Possibilities For A Common Fisheries Development And Management Policy For The Organization Of Eastern Caribbean States (O.E.C.S.), Daven C. Joseph
Theses and Major Papers
The fisheries resources within the EEZs of countries in the Organization of Eastern Caribbean States is not being exploited at their maximum sustainable yield. Fisheries development has however been hampered by a history of these states, little or no sectoral development planning. If member states are to realize any increased socio-economic growth in the fisheries sector, it is imperative that a common fisheries management and development strategy be implemented by these states, in an effort to rationalize the use of scarce financial and technical resources. Such a strategy would involve the pursuance of common goals and objectives and the provision …
The Gulf Of California As A Large Marine Ecosystem, Patricia A. Morrissey
The Gulf Of California As A Large Marine Ecosystem, Patricia A. Morrissey
Theses and Major Papers
Large marine regions characterized by unique bathymetry, hydrography and productivity, within which marine populations have adapted reproductive, growth, and feeding strategies constitute large marine ecosystems (LME) (Sherman and Alexander, 1986). The Gulf of California a semi-enclosed sea off the western coast of Mexico qualifies as a LME as it presents physical and biological characteristics not found in the adjoining Pacific. This area sustains the largest commercial fishery in the country which is the sardine fishery. the sardine population resident in the Gulf of California has coupled its reproductive and migration strategies to the environment of this region. Fluctuations of the …

Malaysia And The Law Of The Sea, Mohd Fadzil Shuhaimi
Theses and Major Papers
The new legal regime of the oceans has brought many changes in the Malacca Strait. The most recent one in the enactment of the Malaysian Exclusive Economic Zone Act 1984 as corollary to its proclamation on the Exclusive Economic Zone in 1980. A year later, the Fisheries Act 1985 was enacted by Malaysia as a result of increasing needs to address new issues in fisheries protection and management in the Malaysian fisheries waters. The conclusion of the 1982 United Nations Convention on the Law of the Sea, among other things, has improvised the concept of transit passage in the straits …

Factors Influencing The Role Of Women In Indonesian Fisheries Development, Melissa A. Upton
Theses and Major Papers
Gender consideration is an essential component of fishery development activities. The purpose of this thesis is to help guide planners and decision-makers who are concerned with understanding the role of women in fisheries development in general as well as in the Republic of Indonesia. Thus, it is partially based upon field research conducted in Indonesia among fishing communities which are representative of different types of fisheries. Justification for research concerning the role of women in the fisheries sector and the reasons why women should be included in development policy and planning are presented in Chapter I. The general research setting, …

Mariculture Management For Pohnpei State, Federated States Of Micronesia, Kevin Brooks Foster
Theses and Major Papers
The Marine Resources Division of Pohnpei State, Federated States of Micronesia is currently engaged in development activities that include the establishment of family scale mariculture projects for community members of remote villages and outer islands. The goal of this undertaking is to supplement subsistence and income generation ventures for community members through the wise use and exploitation of the marine environment. These aims may be jeopardized unless a management plan is devised that reflects the customary marine resource practices as embraced by islanders from each community. The intent of this thesis projects is to devise a mariculture management model that …

Watershed Sciences Faculty Publications
Juvenile rainbow trout Oncorhynchus mykiss stocked in midelevation reservoirs in Utah inhabit shallow nearshore areas and are vulnerable to predation from piscivorous fish and birds. We determined the use and importance of nearshore habitats by (1) measuring habitat selection by, prey availability to, and feeding of juvenile rainbow trout in two reservoirs with populations of predators, and (2) measuring survival and growth rates in the presence and absence of cover in a pond experiment where adult brown trout Salmo trutta were predators. In the reservoirs juvenile rainbow trout (60–120 mm standard length) were abundant in complex inshore habitats but avoided …

Baylor Grounds were defined by a survey of the natural oyster beds in Virginia conducted by Lt. J.B. Baylor, USN, and completed in 1894. The original purpose of the survey was to set aside naturally productive oyster beds for protection from private leasing, which was a controversial concept at the time. Hence the commonly used term 'Baylor Grounds' is synonymous with Virginia's public oystering grounds in the present day. Other surveys, conducted later, have added to the original Baylor acreage, resulting in an estimated 243, 000 acres of public oyster grounds in Virginia. For further information on the oyster industry …
