Fisheries Research Report No. 118 - A Study Into Western Australia's Open Access And Wetline Fisheries, F Crowe, W Lehre, R C J Lenanton
Fisheries Research Report No. 118 - A Study Into Western Australia's Open Access And Wetline Fisheries, F Crowe, W Lehre, R C J Lenanton
Fisheries research reports
Western Australia's wetline fishery potentially includes every licensed fishing boat in the State and encompasses a number of inter-relationships between various boats and commercial fisheries. This study covers the 'wetline' or open access fishery, which encompasses those activities associated with the unrestricted Western Australian fishing boat licence (FBL). The activities associated with this fishery involve any commercial fishing which is not covered by fisheries legislation.
A separate section entitled 'So you want to go wetlining?' is provided at page 101 as an easy reference guide to industry and others interested in wetline fishing. It is recommended that it be read …
Fisheries Research Report No. 115 - Statistical Analysis Of Gascoyne Region Recreational Fishing Study July 1996, Neil R. Sumner, Richard A. Steckis
Fisheries Research Report No. 115 - Statistical Analysis Of Gascoyne Region Recreational Fishing Study July 1996, Neil R. Sumner, Richard A. Steckis
Fisheries research reports
A survey of recreational fishers in the Gascoyne region of Western Australia was conducted in July 1996 to provide information required by fisheries managers. Catch rates, attitudinal, demographic and economic information from boat-based and shore-based fishers was collected by Fisheries Officers. Pink snapper (Pagrus auratus) was the primary species caught by boatbased recreational fishers in the region. Various species of whiting were the predominant catch from shore-based anglers. Most fishers interviewed (80%) supported the introduction of an upper limit on the amount of fish and fillets that a person could take away from the Gascoyne region for personal or family …
Fisheries Research Report No. 114 - The Western Australian Scallop Industry, D C. Harris, L M. Joll, R A. Watson
Fisheries Research Report No. 114 - The Western Australian Scallop Industry, D C. Harris, L M. Joll, R A. Watson
Fisheries research reports
Five separate commercial fisheries target the saucer scallop, Amusium balloti (Bernadi 1861) in Western Australian waters. While the average annual catch from these fisheries is around 600 tonnes of scallop meat, past catches have been highly variable with annual landings ranging from 150 to 4,400 tonnes of meat worth between $2 and $59 million. Consequently, scallops represent one of the larger single-species fisheries operating in Western Australia (WA).
A. balloti has a distribution spanning most of the WA coast, from Broome in the north around to Esperance in the south. Despite this extensive distribution, saucer scallops tend to be restricted …
Fisheries Research Report No. 113 - Catch, Effort And The Conversion From Gill Nets To Traps In The Peel-Harvey And Cockburn Sound Blue Swimmer Crab (Portunus Pelagicus) Fisheries, Roy Melville-Smith, Mark Cliff, Sonia M. Anderton
Fisheries Research Report No. 113 - Catch, Effort And The Conversion From Gill Nets To Traps In The Peel-Harvey And Cockburn Sound Blue Swimmer Crab (Portunus Pelagicus) Fisheries, Roy Melville-Smith, Mark Cliff, Sonia M. Anderton
Fisheries research reports
Over the last few years, there has been considerable interest on the part of commercial fishers to move away from using gill nets, the traditional method for fishing for blue swimmer crabs in Western Australia (WA), to fishing with traps. Blue swimmer crab fisheries in WA are regulated by effort controls and most gill net fishers are restricted to hauling 1,000 metres (1,200 metres in the case of Cockburn Sound) of gill net per day.
The fieldwork in this study was initiated in March 1994 in Cockburn Sound and in January 1996 in the Peel-Harvey Estuary. It was aimed at …
A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck
A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck
All Master's Theses
Satus Creek provides critical habitat for the Yakima River Basin steelhead. A diverse community of riparian vegetation is important for healthy fish habitat; vegetation changes can affect shade, cover, channel structure, water quality, and food availability. The purpose of this thesis is to analyze and illustrate riparian vegetation change, both temporally and spatially, along three separate reaches of Satus Creek. A Geographic Information Systems approach was applied to assess the vegetation change by comparing plant species composition and density on 1949 and 1995 aerial photographs. The GIS approach allowed patterns and trends in the vegetation to be identified. In less …
1999 Wildlife Management Area Threatened And Endangered Species Inventory, Final Report, Robert F. Steinauer
1999 Wildlife Management Area Threatened And Endangered Species Inventory, Final Report, Robert F. Steinauer
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
This study was undertaken to determine the extent of threatened and endangered (T&E) species habitats and high-quality native plant communities on Nebraska Game and Parks Commission (NGPC) Wildlife Management Areas (WMAs). The Nebraska Natural Heritage Program (NHP) is responsible for environmental reviews of state projects that may impact threatened and endangered (T&E) species in Nebraska, including proposed management actions on state Wildlife Management Areas (WMA). These environmental reviews require a significant amount of NHP staff time, and frequently find no adverse impacts associated with the proposed management actions. This survey was undertaken to improve Nebraska Game and Parks Commissions (NGPC) …
Inventory Of The Central Mixed-Grass Prairie Ecoregion Of Kansas And Nebraska, Hillary Loring, Mike Bullerman, Kelly Kindscher
Inventory Of The Central Mixed-Grass Prairie Ecoregion Of Kansas And Nebraska, Hillary Loring, Mike Bullerman, Kelly Kindscher
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
An inventory of potential high quality mixed-grass prairie ranches and large properties within the Central Mixed-Grass Prairie Ecoregion of Kansas and Nebraska was conducted in the spring and summer of 1999. Emphasis during the inventory was placed on identification of relatively intact landscapes. Significant ranches within those untilled landscapes were visited. An interview of the owners or managers of those properties was coupled with a survey of the vegetation. Assessments of quality were based on species composition, continuity of ground cover, observations of livestock impact, and viability of the community types present.
The objectives of this study were to:
1) …
1999 Nebraska Central Mixedgrass Prairie Rapid Ecological Assessment, Mike Bullerman
1999 Nebraska Central Mixedgrass Prairie Rapid Ecological Assessment, Mike Bullerman
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
This document has been prepared in partial fulfillment of the 1999 Central Mixedgrass Prairie ecoregion [CMGP] Rapid Ecological Assessment [REA] contract between the Nebraska Chapter of The Nature Conservancy [TNC] and Michael J. Bullerman [“contractor”]. The contract provided for the survey of selected untilled landscapes within the Nebraska portion of the CMGP ecoregion, excluding the Sandhills. The objectives of this study were to:
1) Identify relatively intact CMGP landscapes within the state of Nebraska,
2) Determine the ecological condition, threats, unique features, and conservation potential of these landscapes,
3) Determine land use practices implemented by landowners,
4) Determine landowner attitudes …
