Fisheries Report No 60 - Amateur Net Fishing Survey Of Two Western Australian South Coast Estuaries In January 1981, D. I. Heald

Fisheries Research Reports

Following the return of the administration of fishing activities in Wellstead estuary and Beaufort Inlet to the Western Australian Government in October 1980, a survey of the amateur net fishing in these two estuaries was undertaken in January 1987, The purpose of the survey was to document usage, species catches and size composition of fish caught in respect of mesh size used and the success rate of amateur net fishermen as compared to their expectation. At the time of the survey, Wellstead estuary had been closed to the sea for 13 months and Beaufort Inlet for 27 months and the …

Fisheries Report No 63 - Assessment Of Artificial Feeds For Battery Culture Of A Freshwater Crayfish, Marron (Cherax Tenuimanus) (Decapoda: Parastacidae), Dr N. Morrissy

Fisheries Research Reports

Performance of juvenile crayfish, 0.1-5 g, on a variety of commercial crustacean feeds was tested under conditions of individual housing ("battery culture"), where sources of additional feed were minimized (detritus), or eliminated (cannibalism) Survival was close, or equal, to 100% over 50 day test periods, a reflection of optimal battery conditions rather than feeding, since survival over 100 days for an unfed (control} group was also 100%. No ecdysiad mortality, or trauma, occurred with crayfish, up to 10g, in compartments of area 75 cm. Growth performance in tests was rated by separate ratios for ecdysial increment and frequency, relative to …

Fisheries Report No 64 - The Western Rock Lobster Fishery 1977 - 1978, R. S. Brown, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster Panulirus cygnus 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 fishing 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 …

Fisheries Report No 67 - The Western Rock Lobster Fishery 1978 - 1979, R. S. Brown, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster Panulirus cygnus is one of the most important single fisheries in Australia and an important export earner for the State. Western Australia produced a record 11 388 tons in 1978/79, out of a total Australian catch of rock lobster of 15 400 tons. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and Hancock (1981) and which are designed to limit the total fishing effort to acceptable levels and to enforce a legal minimum size. It is thus important to constantly monitor the state of …

Fisheries Report No 62 - The Commercial Fisheries Of Temperate Western Australian Estuaries: Early Settlement To 1975, R C.J. Lenanton

Fisheries Research Reports

This report provides a quantitative description of the commercial estuarine fisheries of temperate Western Australia. An account is given of the Long series of historical events which influenced the development of the fisheries and led to their current status. All available catch and effort data covering the years 1898 - 1975 are presented. The use of this long series of historical catch and effort data as an aid to the management of the estuarine fisheries resources is discussed. It is emphasised that interpretations of these data cannot be undertaken effectively without a knowledge of factors such as Life history strategies, …

Vegetation Changes In Four Study Areas At Indiana Dunes National Lakeshore, Kathryn Ann Kerr

Masters Theses

The sampling transects at Indiana Dunes were established to show the pre-burn condition of the vetetation and to monitor the long term effects of burning. However, one year of monitoring showed changes in vetetation that further substantiate the need for the burning program.

Miller Woods (Transect A) has burned frequently in recent years. The one year without fire showed little change in the herbaceous layer. The few notable herbaceous changes might indicate a transition to a more mesic community, but should be viewed skeptically because of the wet season in 1982.

Nearly half of the small shrub species at Miller …

Annean Station Management Plan, A A. Mitchell

Resource management technical reports

Annean Station's carrying capacity has been estimated at 8,340 sheep on its 168,539 hectares. The halophyte pastures of Carnegie Land System were in good condition while those of Mileura Land System were in poor condition. The wandarrie pasture of the Belele Land System was in fair to poor condition. This system comnprises 34 per cent of Annean's area and is estimated as capable of presently carrying 2,900 stock.

Fisheries Report No 59 - Potential Fisheries Capability Of The Ord In The Short, Medium And Long Terms, Dr N. Morrissy

Fisheries Research Reports

This report examines the history, future and problems of various methods for development and exploitation of the fisheries resources of the Ord.

The primary resource is the array of native fish and crustacean species, with the possible introduction of other desirable or noxious species being a subject for consideration.

Water resources, supporting these species, are the remaining natural Ord River downstream from the Diversion Dam at Kununurra, the stillwaters of Lake Kununurra and Lake Argyle, and, for aquaculture, the controlled distribution of water supply over the flat land of the irrigation system (Fig. 1). Another recognized resource is the climatic …

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 …

Use Of Hydroelectric Dams To Control Evaporation And Salinity In The Colorado River System, Larry J. Paulson

Publications (WR)

The main stem reservoirs on the Colorado River comprise one of the largest and most heavily used freshwater bodies in the nation. These reservoirs (Lake Powell, Lake Mead, Lake Mohave and Lake Havasu) can store up to 53,590,400 acre-feet of water at their maximum capacities. Nonetheless, local water shortages still exist in some areas of the Colorado River Basin. There is also concern that salt concentrations are approaching levels that could severely affect municipal and agricultural uses. Water shortages will become even more acute as demands for water increase with continued urban and agricultural development in the basin. Water conservation …

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 …

Mammals Of The Northern Great Plains, J. Knox Jones Jr., David M. Armstrong, Robert F. Hoffmann, Clyde Jones

University of Nebraska State Museum: Mammalogy Papers

For the purposes of this book, the Northern Great Plains are defined as the states of Nebraska, North Dakota, and South Dakota. As a physiographic concept, the northern part of the great interior grasslands of North America is, of course, much broader in geographic extent than the Dakotas and Nebraska, but the three states lie in the heart of the region, and thus the title for this work seems appropriate. Our expectations in writing Mammals of the Northern Great Plains were to provide a comprehensive, yet semitechnical, treatmeat of free-living mammals that would prove useful to specialist and nonspecialist alike. …
