Environmental Evaluation Report Onn Various Completed Channel Improvement Projects In Eastern Arkansas, Edward E. Dale Jr., Thomas M. Buchanan, Richard L. Meyer, Robert T. Huffman Jan 1975

Environmental Evaluation Report Onn Various Completed Channel Improvement Projects In Eastern Arkansas, Edward E. Dale Jr., Thomas M. Buchanan, Richard L. Meyer, Robert T. Huffman

Arkansas Water Resources Center Technical Reports

The objective of this report is to evaluate the beneficial and adverse effects that certain channel improvement projects have had on the natural or man-made environments of selected areas in eastern Arkansas. This evaluation will be used as a baseline for determining the immediate and long-term effects that a project may have on the existing environment of the Village Creek Basin.

Fisheries Report No 19 - The Western Rock Lobster Fishery 1973 - 1974, G. R. Morgan, E H. Barker Jan 1975

Fisheries Report No 19 - The Western Rock Lobster Fishery 1973 - 1974, G. R. Morgan, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster* 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 catches. Inherent …

Fisheries Report No 18 - Tuna Survey In Waters Off The Western Australian Coast During The Period August 1973 To August 1974, J. P. Robins Jan 1975

Fisheries Report No 18 - Tuna Survey In Waters Off The Western Australian Coast During The Period August 1973 To August 1974, J. P. Robins

Fisheries Research Reports

In September 1972, Markwell Ross Fisheries Pty Ltd (a subsidiary fishing division of Q.U.F. Industries Ltd) approached the Western Australian Department of Fisheries and Fauna (now Department of Fisheries and Wildlife) for assistance in the development and carrying out of a purse seining programme using the 25m rock lob­ster vessel F.B. Western Star.

Negotiation and agreement was reached, with the objective to under­take and carry out an investigation into the feasibility of developing a purse seine fishery for tuna in Western Australian waters. The Department of Fisheries and Wildlife (Development Section) supplied, on loan, capital fishing equipment (purse seine net, …


Fisheries Report No 16 - Notes On The Wildlife Of A Proposed Nature Reserve Around Lake Grace And Lake Chinokup, Western Australia, N. L. Mckenzie, W. K. Youngson Jan 1975

Fisheries Report No 16 - Notes On The Wildlife Of A Proposed Nature Reserve Around Lake Grace And Lake Chinokup, Western Australia, N. L. Mckenzie, W. K. Youngson

Fisheries Research Reports

During 1972 and 1973 plants and vertebrate animals were collected and recorded from a proposed 22 000 ha nature reserve centred on a chain of salt lakes in south-western Western Australia (33° 10' S - 33° 35' 8 and 118° 19' B - 118° 29' E).

The dominant plant species were collected, the structural formations desert bed and a vegetation map produced. Seven species of native terrestrial mammal and three species of bat were recorded.

Three of the terrestrial species are endemic to southwestern Western Australia, and two of these - Pseudomys occidentalis and Sminthopsis granulipes - are regarded as …


Fisheries Report No 17 - Some Aspects Of Tuna And Its Potential In The Oceanic Waters Off Western Australia, J. P. Robins Jan 1975

Fisheries Report No 17 - Some Aspects Of Tuna And Its Potential In The Oceanic Waters Off Western Australia, J. P. Robins

Fisheries Research Reports

In this report an endeavour has been made to describe very briefly the growth of the tuna fishery in Australia, world production, utilisation, price and future demand, tuna species descriptions, species occurrence around the Australian coast and the results of two aerial surveys for tuna off. the west and north-west coasts of Western Australia.
