Fisheries Report No 34 - The Status Of The Salt-Water Crocodile In The Glenelg, Prince Regent And Ord River Systems, Kimberley, Western Australia, A. A. Burbidge, H. Messel Jan 1979

Fisheries Report No 34 - The Status Of The Salt-Water Crocodile In The Glenelg, Prince Regent And Ord River Systems, Kimberley, Western Australia, A. A. Burbidge, H. Messel

Fisheries Research Reports

Counts were made of Salt-water Crocodiles (Crocodylus porosus) in the estuarine portions of the Glenelg, Prince Regent and Ord River systems of the Kimberley Division, Western Australia. During the survey 581 crocodiles were seen, including 143 hatchlings. The number of non-hatchling crocodiles in present the Glenelg system is estimated to be 200 to 259, in the Prince Regent 190 to 246 and in the Ord 235 to 306 (95% confidence limits).

The number of non-hatchling crocodiles present in the six Kimberley river systems now counted is estimated to be between 957 and 1243 (95% confidence limits) and we believe that …


Fisheries Report No 38 - The Shark Bay Prawn Fishery (1970 - 1976), J. W. Penn, R. W. Stalker Jan 1979

Fisheries Report No 38 - The Shark Bay Prawn Fishery (1970 - 1976), J. W. Penn, R. W. Stalker

Fisheries Research Reports

The existence of prawn stocks in Shark Bay, Western Australia, has been known since 1904 when the sailing ketch "Rip" on charter to the Western Australian Government, trawled large quantities of prawns from the area between Bernier Island and the mainland, Gale (1905). Although the Fisheries research vessel "Lancelin" trawled potentially commercial quantities of prawns from Shark Bay in the early 1950's, it was not until 1962 that a regular fishery was begun.

Today the prawn stocks of Shark Bay support Western Australia's largest and most consistent prawn fishery, having an annual production currently exceeding 2 000 tonnes. The catch …

Niobrara-Missouri River Fishery Investigations, Larry W. Hesse, Gene Zeurlein, Roger Vancil, Leonard Koziol, Brad Newcomb, Leigh Ann Retelsdorf

Nebraska Game and Parks Commission: Publications

The Niobrara River heads in the table lands of eastern Wyoming and flows 786 kilometers (km) eastward across Nebraska joining the Missouri River near the town of Niobrara, Nebraska. The Niobrara is the largest Missouri River tributary between the last two mainstem impoundments (Lake Francis Case and Lewis and Clark Lake). Fish movement up the Niobrara is prevented by Nebraska Public Power District's (NPPD's) Spencer Hydroelectric Dam, 63.3 km upstream from the river mouth. The lower reach of the river is turbid and carries a considerable load of sand, silt, and organic debris into the Missouri River. The mean annual …

Fisheries Report No 28 - The Western Rock Lobster Fishery 1974-1975, G. R. Morgan, E H. Barker Jan 1977

Fisheries Report No 28 - The Western Rock Lobster Fishery 1974-1975, G. R. Morgan, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster Panultrus eygnus is one of the most important single fisheries in Australia and an important export earner for the State. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and which are designed to limit the total effort to acceptable levels and to enforce a legal minimum size. It is thus important to constantly monitor the state of the fishery both to ensure that the effort is remaining within the accepted limits and that the regulations are adequately performing their function of maintaining reasonably stable …


Fisheries Report No 31 - Pecten Scallop Survey On Southern Geographe Bay, September 1976, D. I. Heald Jan 1977

Fisheries Report No 31 - Pecten Scallop Survey On Southern Geographe Bay, September 1976, D. I. Heald

Fisheries Research Reports

Reports of Pecten scallops in Geographe Bay in late 1975 were followed up by a preliminary stock survey in February 1976 using 1.22 m dredges and by a more extensive survey in September 1976 using 1.22 m and 2.25 m scallop dredges and a 0.5 m* Baird grab. Two very limited concentrations of scallops were located adjacent to rough ground. The best dredge catch rates were equivalent to 44 kg per hour per standard haul and the maximum grab catch was equivalent to a density of six scallops per square metre. The extremely rough terrain resulted in considerable damage to …

Fisheries Report No 24 - The Status Of The Salt-Water Crocodile In Some River Systems Of The North-West Kimberley, Western Australia, H. Messel, A. A. Burbidge, A. G. Wells, W. J. Green

Fisheries Research Reports

Counts were made of Salt-water Crocodiles (Crocodylus porosus) in the estuarine portions of four river systems in the northwest Kimberley, Western Australia - the Lawley, Mitchell, Roe-Hunter and Prince Regent. During the ten day survey 463 crocodiles were spotted, including 109 hatchlings. The maximum number of non-hatchling crocodiles present tin the four systems is estimated at 697. Very few large crocodiles were seen.

Populations were particularly small in the Lawley and Mitchell Rivers and the potential for recovery in this area is also small. Prospects for recovery in the Roe-Hunter and Prince Regent were a little better but further surveys …


Distribution Of Stream Pollution In Lake Water, Richard W. Tew, Samuel S. Egdorf, James E. Deacon May 1976

Distribution Of Stream Pollution In Lake Water, Richard W. Tew, Samuel S. Egdorf, James E. Deacon

Publications (WR)

Wastewater effluent-laden waters from Las Vegas Wash (LVW) form a density current that may be detected in Boulder Basin of Lake Mead at considerable distances from the wash estuary. This led to the suspicion that water from the inflowing stream [40 mgd (1.5 X 105 cu m/day)] might not be rapidly diluted in the enormous volume of the lake [19 mil acre-ft (2.3 X 1010 cu m)], but might persist as a recognizable entity to the vicinity of the intake of a major water source for populous Clark County, Nev.

Because of the detection sensitivity implicit in the …

Evaluation Of A Recreational Lake Rehabilitation Project, Clyde Brashier Aug 1975

Evaluation Of A Recreational Lake Rehabilitation Project, Clyde Brashier

2019: Dr. Clyde Brashier

Lake Herman, a recreational, shallow, warm water prairie lake near Madison, South Dakota drain in extensively cultivated watershed and acts as a siltation basin for a chain of four lakes. The lake is more than half silted in and since 1968 various rehabilitation efforts have been made, including the construction of silt traps and lake dredging.

Continuation of the monitoring of twenty plus chemical levels and biological populations of green algae, blue-green algae and diatoms has revealed two major changes: (1) ortho phosphate and total phosphorus levels (which increased markedly with the beginning of dredging) have decreased since dredging has …


Vegetation Development In Relation To Age Of River Stabilization Structures Along A Channelized Segment Of The Missouri River, John Arthur Vaubel Jun 1975

Vegetation Development In Relation To Age Of River Stabilization Structures Along A Channelized Segment Of The Missouri River, John Arthur Vaubel

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

During the summer of 1974, I sampled sites of vegetation representative of successional trends in plant communities along the Missouri River floodplain from Sioux City, Iowa, to Rulo, Nebraska. Five district community types listed from youngest to oldest are as follows: Salix spp. – dominated, Populus deltoides – dominated, Platanus occidentalis-Ulmus rubra – dominated, Tilia americana-Quercus rubra – dominated, and Quercus macrocarpa-Carya ovata – dominated vegetation.

The technique of relating vegetation succession to age of river stabilization structures was found to be useful and offered a quite precise method of developing a timescale …

Raising Wood Ducks, Richard L. Nelson Jan 1975

Raising Wood Ducks, Richard L. Nelson

Nebraska Game and Parks Commission: Publications

Numbered among Nature's most colorful creatures, wood ducks willingly accept a helping hand from man in establishing new homes. These birds adapt well to suitable habitat, and you can play an important part in bringing the wood duck to locations where they do not now nest. For groups or individuals who are willing to expend the effort necessary to undertake a wood duck restoration project anti see it to completion, it is an exceptional gift from today's generation to those of decades and centuries to come. Many areas in Nebraska provide suitable wood duck habitat, but do not have a …

The Gulf-Atlantic Waterway: Instrument To Increase Profit Margins In The Jacksonville Area, Jacksonville Area Chamber Of Commerce Research Department, Jay A. Smith

Waterways and wildlife

The purpose of this report is to reassess the economic value that the Gulf-Atlantic Waterway will have on Duval county. This will show the direct relationship on the Port and the indirect benefits to other segments in our economy. This is needed for three reasons: 1. The last economic study was completed by the Corps of Engineers with the assistance of Arthur D. Little, Inc., a national consulting firm, in 1962. So, it has been almost twelve years since an economic report has been started from scratch. 2. The economic reports in the past have been mainly concerned with cost/benefit, …

The Economic Value Of Natural Areas For Recreational Hunting, Kenneth Gene Holbrook Jan 1970

The Economic Value Of Natural Areas For Recreational Hunting, Kenneth Gene Holbrook

KWRRI Research Reports

The pressures of population growth, urbanization, and improved transportation are diminishing the availability of quality naturalistic sites for recreation while at the same time producing greater demands for their use. One cause contributing to the reduction in acreage in naturalistic areas is the construction of reservoirs. The recreational hunting value of the naturalistic area to be inundated should be considered as a negative consequence in the economic evaluation of a proposed reservoir site.

This study utilized hunting data collected by the Kentucky Department of Fish and Wildlife, from the 120 Kentucky counties to estimate the economic, value of the average …


Some Ecological Relations Of Fairy Shrimps In Alkaline Habitats Of Nebraska, D. B. Mccarraher Jan 1970

Some Ecological Relations Of Fairy Shrimps In Alkaline Habitats Of Nebraska, D. B. Mccarraher

Nebraska Game and Parks Commission: Staff Research Publications

Ecological studies on the distribution of fairy shrimps have been made from 246 sites in the sandhills region of Nebraska. New records for Nebraska have been established for Artemia salina, Branchinecta campestris, B. lindahli, B. mackini and Cyzicus mexicanus. Seasonal populations of shrimp have been located in habitats containing permanent fish populations. Water mineralization was the dominant environmental condition related to the distribution of phyllopods with sodium and potassium compounds predominating in the strongly alkaline lakes. Several of the Artemia lakes were classified as hydroxide sites. Many of the alkaline ponds, where B. lindahli and B. campestris flourish, are …


The Ocean Resource: A Scenario For Its Control, Ronald Poitras Dec 1969

The Ocean Resource: A Scenario For Its Control, Ronald Poitras

Marine Affairs Theses and Major Papers

As man expands his horizons on planet earth, he is beginning to turn increasingly to the oceans as a source of resources, and at a pace commensurate with the growth of his needs and his technical ability. Traditionally the deep sea has always been a "no man's land," an unlimited source of space to be traversed and used infrequently. A scarcity of natural resources and an abundance of human extensions (i.e. technology) are together making deep ocean seclusion a thing of the past. Increasing use of a particular resource is a limited space sooner or later implies an increasing need …

Fisheries Report No V (5) - Report On Marron In Farm Dams (Cherax Tenuimanus), N M. Morrissy

Fisheries Research Reports

A programme of selling marron (Cherax tenuimanus) to country dwellers for stocking farm dams, has been carried out by the Pemberton Trout Board for the past few years with considerable financial gain. In this case permission to sell the marron was granted by the Department of Fisheries and Fauna so as to encourage the provision of stocks of this large, freshwater crustacean for farmers in the dryer inland areas of the Southwest which are remote from sources of fresh fish and from natural stocks of marron.

The marron, however, have been sold indiscriminately, upon request, without any advice as to …

The Effect Of A Large Reservoir On Local Government Revenue And Expenditure, Clyde T. Bates Jan 1969

The Effect Of A Large Reservoir On Local Government Revenue And Expenditure, Clyde T. Bates

KWRRI Research Reports

Development of a large multi-purpose reservoir within the area of their jurisdiction may affect property ta.x revenue and expenditure of county governments and school districts. Privately owned land sold to a federally sponsored reservoir is not subject to property taxes because of the doctrine of intergovernmental immunity. Local officials often assume that this loss of assessment will reduce their tax revenue and thereby their fiscal ability to provide an acceptable level of government services. They may also expect the influx of construction workers or the disruption of existing facilities to increase the cost of providing these services. The study approaches …


Patterns Of Land Use Change Around A Large Reservoir, Billy R. Prebble Jan 1969

Patterns Of Land Use Change Around A Large Reservoir, Billy R. Prebble

KWRRI Research Reports

Reservoirs are built to control floods, provide water for irrigation and municipal supply, generate electric power, augment low flows for navigation and water quality control, and provide improved fishing and recreation opportunity. A reservoir is justified if the benefit it provides to society exceeds the cost to develop it. Much research has been done to determine the benefit of a water resources development to society as a whole. Some research has explored the benefit of such a facility to a region. Very little research exists on the effects of a reservoir on the immediately surrounding area.

It seems reasonable that …
