Fisheries Report No 50 - Feasibility Trawling Activities In The Great Australian Bight By The Korean Trawlers Dong Ban 91 And Dong Won 509 During The Period 15.11.79 To 12.1.80, Michael H. Walker, Stuart J. Blight, Gerald M. Cliff

Fisheries Research Reports

Four Korean fishing trawlers operated in Western Australian waters, largely on the Northwest shelf, during 1979 under State/Commonwealth feasibility fishing arrangements. Two of these vessels, Dong Bang 91 and Dong Won 509, were given permission by Government, late in 1979, to conduct demersal trawling operations in the Great Australian Bight between longitudes 116°£ to 138°E and outside of 12 miles from shore.

Two observers from the Western Australian Department of Fisheries and Wildlife were involved with monitoring the activities of these vessels at sea in the Bight.

This report describes the operations of these Korean vessels in detail and represents …

Fisheries Report No 51 - 'Taiyo Maru 71" Demersal Trawling Cruise In Western Australian Coastal Waters South Of 21 S, July-September, 1979, D. I. Heald, M. H. Walker

Fisheries Research Reports

A Japanese demersal trawler, 'Taiyo Maru 771' was given special permission to conduct exploratory trawling in the period 73.7.79-16.9.79 off the Western Australian coast between 21°S Latitude and 35°30'S Latitude, an area which partly overlapped the fishing grounds for the western rock Lobster. The vessel was required to complete a catch, fishing effort and species composition log book issued by the Commonweath Department of Primary Industry. Two Western Australian Department of Fisheries and Wildlife observers on board monitored fishing operations for the entire duration of the cause and undertook research.

Details of each trawl conducted are given and discussed. Catch …

Fisheries Report No 57 - Exploratory Fishing For Spanish Mackerel In Waters Off Western Australia During The Period June 16 To October 16, 1981, K. Donohue, P. Edsall, J. Robins, R. Tregonning

Fisheries Research Reports

The results of catching Spanish mackerel (Scomberomorus commerson) by gillnet and troll lines during a survey extending from June 16 to October 16 1981 are presented.

The catch rate of mackerel obtained by trolling with six lines was found to be 14.35 times greater than that by gillnet, measuring 0.75 miles in length.

From the results presented, a professional fisherman should be able to assess the economic viability of fishing commercially for Spanish mackerel.

Analysis of biometrial and biological data on fish caught allowed determination of (a) length/weight relationship of (i) Spanish mackerel (ii) wahoo (Acanthocybium solandri); (b) sex ratios …

Wildlife Values Versus Human Recreation: Ruby Lake National Wildlife Refuge, Stephen H. Bouffard

United States Fish and Wildlife Service: Publications

Expanding human populations are making increased recreational demands on National Wildlife Refuges (NWR). The U.S Fish and Wildlife Service (FWS) is trying to accommodate these demands whenever possible. An important, but not primary objective of NWRs is to provide for various public uses, including recreation (U .S. Fish and Wildlife Service 1976a). The Refuge Recreation Act of 1962 (16 U.S.C. 460K-460K-4) authorizes the FWS to allow recreational uses on NWRs, National Fish Hatcheries and similar lands. This act specifies that all recreational uses must be secondary to the primary purpose of the refuge. While most refuge recreation programs do not …

Habitat Models For Land-Use Planning: Assumptions And Strategies For Development, Adrian H. Farmer, Michael J. Armbruster, James W. Terrell, Richard L. Schroeder

United States Fish and Wildlife Service: Publications

Wildlife managers have long recognized that management goals must be constrained by the availability and suitability of habitat. This recognition, combined with ever increasing land development pressures, has resulted in environmental legislation emphasizing systematic approaches to collection and analysis of habitat information. Wildlife planners have responded with a variety of approaches to the development of models that quantify habitat requirements.

Fisheries Report No 52 - The Present State Of The Western Australian Fishery For Australian Salmon, Michael H. Walker

Fisheries Research Reports

In 1975, following a number of years of research by the CSIRO Division of Fisheries and Oceanography, it was decided to conduct. a renewed programme cooperatively between CSIRO and W.A. Department of Fisheries and Wildlife. The results of the joint programmes will be presented elsewhere.

Conservation Measures In The Interim Fishery Management Plan For Atlantic Groundfish, Andrew P. Matykiewicz

Marine Affairs Theses and Major Papers

The conservation measures used in the Interim Fishery Management Plan for Atlantic Groundfish (IFMP) were analyzed. The management techniques used include a minimum mesh size, minimum fish size and haddock spawning area closure. However the mesh regulation does not adequately address the IFMP conservation objectives. Without amendment, the IFMP cannot prevent overfishing as it is required to do by the Magnuson Fishery Conservation and Management Act (MFCMA). The use of a non-numeric Optimum Yield (OI) for groundfish is inappropriate without a definition of overfishing and without a contingency plan to prevent overfishing.

California's Central Valley Wintering Waterfowl: Concerns And Challenges, David S. Gilmer, Michael R. Miller, Richard D. Bauer, John R. Ledonne

United States Fish and Wildlife Service: Publications

Few places on the North American continent can boast of the concentrations of migratory birds that winter in the Central Valley of California. Long before agriculture and industrialization came west, this great valley served as a major wintering ground for millions of migratory birds. Fall flights of waterfowl, shorebirds, waders, raptors, and passerines returned annually to inhabit the vast wetland, riparian, and grassland habitats which covered the valley floor (Dasmann 1966, Bakker 1971).
Major changes in the Central Valley during the last century have profoundly influenced its physical and biological features. Wetland, riparian, and grassland habitats have been devastated by …

Current Status And Management Challenges For Tule White-Fronted Geese, Daniel E. Timm, Michael L. Wege, David S. Gilmer

United States Fish and Wildlife Service: Publications

Since large, dark tule white-fronted geese (Anser albifrons gam belli Hartlaub) were first described in Texas over a century ago by Hartlaub (1852), and again 65 years later in California by Swarth and Bryant (1917), tule geese have been the subject of at least 14 studies in California and 8 attempts to locate summering birds in the Artic. Central questions of these efforts have been: Is the tule goose a distinct subspecies? What is their range and population size? How can the birds be identified? and What threatens their existence?
The purpose of this paper is to present the …

The Influence Of Habitat Variation On The Morphology And Physiology Of Plethodon Wehrlei (Fowler And Dunn) In West Virginia, Sharon Kay Gross

Theses, Dissertations and Capstones

High elevation, low elevation and cave populations of Plethodon wehrlei (Fowler and Dunn) in West Virginia were compared to determine the influence of habitat variation on morphology and physiology. Discriminant analysis of 14 external morphological characters and 11 skeletal characters revealed a similar morphology for the three populations. Comparisons of critical thermal maxima showed a positive correlation to habitat temperature. Dehydration studies revealed that the high elevation population was more resistant and tolerant to water loss than the cave and low elevation populations.

A Distributional And Taxonomic Study Of The Adults Of The Family Hydropsychidae (Trichoptera) In West Virginia, Toni Ann Phillips

Theses, Dissertations and Capstones

A survey of the adult Hydropsychiclae revealed 39 species, 14 of which were state records. The adult hydropsychids were collected from various locations throughout West Virginia. The most common species Hydropsychidae were Hydropsyche morosa, H. sparna, Cheumatopsyche analis, C. campyla, and Diplectrona modesta. Most of the species did not appear to be limited to any one particular drainage basin. Several species exhibited a preference for stream order (headwaters, middlereaches, large rivers). Aphropsyche monticola, Parapsyche apicalis, Cheumatopsvche wrighti, C, gyra, and Hydropsyche alhedra preferred the fast-flowing headwater streams in the higher elevations of the state. Macrostemum zebratum, Potomyia flava, Hydropsyche phalerata, …

Wild Commercial Fishery Of Arkansas, Tommie Crawford, Mike Freeze

Journal of the Arkansas Academy of Science

Arkansas' wild commercial fishery industry was surveyed to evaluate commercial fish products produced within the state. The total wild commercial catch for the period of 1 July 1980 to 30 June 1981 was approximately 8,680,124 kg with a value of $6,245,967. These values represent an increase of approximately 3% from the previous year. The bulk of the commercial harvest was made up of buffalo fishes (Ictiobus spp.), catfishes (Ictalurus spp), gars (Lepisosteus spp.) and carp (Cyprinus carpio). The number of commercial fishermen remained relatively unchanged from 1979-1980, with 3,843 licensed fishermen operating on the state's waterways. The number of licensed …

Effects Of Water Released From Stratified And Unstratified Reservoirs On The Downstream Water Quality, Stephen B. Smith

Journal of the Arkansas Academy of Science

Water quality samples were collected from the Little River system in Pine Creek Lake, Oklahoma, and Gillham Lake, Arkansas, and their associated tailwaters during the winter (reservoirs unstratified) and summer (reservoirs stratified) of 1980. Downstream water quality was not affected by reservoir water releases while the reservoirs were unstratified. When the reservoirs were stratified water quality in the tailwaters was dependent on the release depth of the water. The practice of flushing out a tailwater following an extended low flow period should be examined on a site by site basis. Anoxic water released from a reservoir may contain high amounts …

Evaluation Of Instream Flow Methodologies For Fisheries In Nebraska, Phil Hilgert

Nebraska Game and Parks Commission: Publications

Five instream flow methods were applied to a variety of streams within the state of Nebraska. These were (1) the Tennant method, (2) a modification of the Tennant method, (3) IFG1 A, a single cross-section average-parameter method, (4) the Incremental method, using the WSP hydraulic simulation program, and (5) the Incremental method, using the IFG4 hydraulic simulation program.

Each method was applied following standard published procedures, and instream flow recommendations were developed for the streams addressed using each method separately. Evaluation of the methods showed that the modification of the Tennant method overcame some of the deficiencies of the Tennant …

Habitat Use By Nesting And Roosting Bald Eagles In The Pacific Northwest, Robert G. Anthony, Richard L. Knight, George T. Allen, B. Riley Mcclelland, John I. Hodges

United States Fish and Wildlife Service: Publications

The American bald eagle (Haliaeetus leucocephalus) was designated our national symbol in 1782. Since that time, populations of the species have declined due to a combination of factors including habitat loss, shooting, and environmental pollutants. As a result, in 1978 the U.S. Department of Interior officially listed the species as endangered in 43 of the 48 contiguous states and threatened in Oregon, Washington, Michigan, Wisconsin, and Minnesota. The bald eagle is protected under the Endangered Species Act, Migratory Bird Treaty Act, and the Bald and Golden Eagle Protection Act. These pieces of legislation protect the species from direct …

Waterfowl Production At Malheur National Wildlife Refuge, 1942-1980, John E. Cornely

United States Fish and Wildlife Service: Publications

Malheur National Wildlife Refuge (NWR), Harney County, Oregon, is an important breeding area for Pacific Flyway Waterfowl. Trumpeter swans (Olor buccinator), Canada geese (Branta canadensis), and 14 species of ducks nest at Malheur NWR. The refuge is one of the most important redhead (Aythya americana) nesting areas in the western United States. Malheur NWR was established by President Theodore Roosevelt in 1908, primarily as a nesting area for migratory birds. The refuge also serves as an important migration stop for thousands of waterfowl and other migratory birds. Originally the refuge was called Malheur Lake …

Status Of The Habitat Evaluation Procedures, Mel Schamberger, William B. Krohn

United States Fish and Wildlife Service: Publications

The 1970s was a decade of increased awareness of environmental problems, and emphasis was placed on the development of procedures for predicting impacts of proposed developmental activities on natural systems. Impact assessment has evolved from a focus on species numbers, human use, species richness, and related methods to include the investigation of habitat as a supplemental or alternative approach to environmental planning, mitigation, species management, and impact assessment (Schamberger 1979, U.S. Fish and Wildlife Service 1980a, 1980b). The impetus for habitat-based assessment techniques came primarily from two sources: (1) environmental legislation requiring noneconomic project evaluations; and (2) an awareness within …

Influence Of Cooperative Wildlife And Fishery Units On Graduate Education And Professional Employment, Rollin D. Sparrowe

United States Fish and Wildlife Service: Publications

In June 1982, several private conservation organizations will join the Iowa State University, and the Iowa Conservation Commission, in a 50-year celebration of the Cooperative Research Unit concept. The first Cooperative Wildlife Research Unit began there in 1932 in response to a recognized need for trained biologists and scientific information in the field of wildlife conservation. The unique partnership between federal, state, university, and private entities that resulted, evolved into the current nationwide program. There are currently 21 wildlife units, 26 fishery units, and 3 combined fish and wildlife units at 31 universities in 29 states (Figure O. The Fishery …

Biological and physical data were collected from nine habitats on the Missouri River near Washburn, North Dakota. Sampling was conducted from mid-July to mid-October 1979 to compare the relative values of the habitats for fish and macroinvertebrates.

Aquaculture In Recirculating Cooling Water From An Electric Generating Plant, John G. Woiwode, Ira R. Adelman

Journal of the Minnesota Academy of Science

Recirculating cooling water from an electric generating plant accumulated dissolved and suspended solids up to ten times that of the make-up water from the Mississippi River. Channel catfish (Ictalurus punctatus) and tilapia (Tilapia mossambica) were grown in the cooling water, in clear well water, and in a mixture of the two for seven months as part of an investigation of the use of cooling water for commercial aquaculture. Health of both species was generally excellent In test and control waters; growth was commercially acceptable; bioaccumulation of contaminants was negligible. Organoleptic quality was not acceptable, although the cause of the off-flavor …

Warmwater Fish Community Of A Cool Tailwater In Arkansas, Richard A. Frietsche

Journal of the Arkansas Academy of Science

A diverse warmwater fish community has persisted in the Lake Greeson tailwater, despite hydropower releases of cold hypolimnetic water. Forty-eight species of fish were collected by electrofishing in the upper 16.1 km of the tailwater. Hydropower releases have reduced the abundance of some of the warmwater sport fish in the upper tailwater, and their populations are probably maintained in part by recruitment from downstream. Angling effort has been diverted from the warmwater sport fish populations to a put-and-take trout fishery.

Water Quality And Benthic Invertebrate Communities In Lake Greeson Tailwater, Stephen B. Smith

Journal of the Arkansas Academy of Science

The Little Missouri River below Lake Greeson, Arkansas, was sampled for water quality and benthos during summer 1979. The hydropower turbine water intakes, 20 m below the lake surface, released hypolimnetic water into the tailwater. Downstream water temperatures, total organic matter, and total inorganic matter varied considerably and benthic invertebrate communities immediately below the dam were stressed by waters released for power generation. Detrimental effects from altered temperature and flow regimes had decreased by 16.1 km downstream, where invertebrate communities were typical of less stressed environments.

Optimum Yield And The Fcma: Uneven Distribution Of Management Burden, Herrick J. Johnson

Marine Affairs Theses and Major Papers

Until the establishment of the Fishery Conservation and Management Act of 1976 (FCMA), fish outside the United States' twelve mile fishery zone were, according to international law, common property and belonged to the nation or individual that caught them. This common property law was based on the concept that fish resources were so large that no amount of fishing would interfere with the right of others to catch fish. Modern technology, however, has created equipment that enabled foreign and domestic fishermen to over-fish the resource. A reduced domestic catch led coastal fishermen to support a bill that unilaterally extended the …

A Quantitative Description Of Migratory Behavior Of The Brown Shrimp (Penaeus Aztecus) With Applications In Fisheries Management, Anne Madolyn Babcock

OES Theses and Dissertations

A quantitative description of the migratory behavior of the brown shrimp, Penaeus aztecus, was established using the density approach. A theoretical time density was estimated by the proportion of catch and catch per boat hour NOAA-NMFS fisheries statistics collected in Pamlico Sound, the Neuse River, and Core Sound. A clear quantitative description of brown shrimp migratory timing is found in the time densities. The impact of various physical tactors on the progress of the fishery in time and space can be objectively evaluated by using the time density statistics as dependent variables in modeling efforts. The distributions also enable …
