Rate Of Growth As A Method Of Assessing Water Quality, George L. Johnston

Masters Theses

A study of the Embarras River basin was conducted to determine if rate of growth could be used as an indicator of water quality. Six species of sucker were collected from five locations using hand seines and electrofishing gear from December 1970 to December 1971. Tests of eighteen water quality parameters were conducted from November 1970 to November 1971.

The fish were measured and scale samples taken. The rate of growth of the fish taken at the five stations was analyzed and compared using the single classification analysis of variance. Condition factors were also compared.

Although there was some difference …

Fisheries Report No 12 - Results Of A Biological Survey Of A Proposed Wildlife Sanctuary At Dragon Rocks Near Hyden, Western Australia, N. L. Mckenzie, A. A. Burbidge, N. G. Marchant

Fisheries Research Reports

In 1972, three visits were made to an area of vacant crown lam 30 kilometres south-south~east of Hyden, Western Australia.

A preliminary survey was made in April 1972 and following this recommendations were made on the equipment and staff required for a detailed survey of the vegetation and animals.

From the 30th July to the 4th August 1972, a team from the Fauna Research Branch of the Department of Fisheries and Fauna began a detailed fauna survey.

Between the 20th August and the 25th August 1972, the fauna survey was continued am a botanist from the Western Australian Herbarium undertook …

A Conceptual Draft Of A Dynamic Hydro-Biological Model For Lake Mead, L. G. Everett, Bureau Of Reclamation

Publications (WR)

Food and energy transformation in an aquatic system must be understood in order to develop a simulation approach. This report provides a comprehensive study of an aquatic ecosystem. The objectives of this report are to show: (1) the biological relationships in an aquatic system (2) the role of nutrients in the biological cycle (3) the role of abiotic factors in a limnetic environment (4) the status of the art of "Eutrophication modeling".

Fisheries Report No Vii (7) - Results Of A Biological Survey Of The Millstream Area, A. A. Burbidge Dr

Fisheries Research Reports

Millstream has long been recognised as an unique and outstanding area, both scenically and from a biological aspect. The area of prime interest consists of a series of deep pools in the bed of the Fortescue River (about 15 miles long including Gregory Gorge) and the springs and streams which feed them. Most of the springs are in the sides of the river bed but one of the largest is about 1% miles to the south. This feeds a swift flowing stream running north into the river bed.

The first Europeans to see the area were the exploring party led …
