This is the final report for FIRTA project 1981-056. The principal objective has been to study the application of real-time satellite-derived sea surface temperature measurements in assisting particular fisheries located in southern waters of Australia. Initially proposed for a three year period from 1981 to 1984, the project was granted an extension into a fourth year. It has been jointly conducted by the School of Electrical and Electronic Engineering of the Western Australian Institute of Technology, and the Remote Sensing Section of the CSIRO Division of Groundwater Research.

This project was the first use of satellite near real-time imagery in the Australian fishing industry, and only became possible with the construction of a NOAA receiving station at WAIT. Overseas experience suggested satellite imagery could be of benefit to Australia, and in broad terms, the project set out to prove this. Three major steps were required in reaching that objective. First, to gather and process satellite data. Second, to obtain catch and related data from the fishermen concerned. Third, and most importantly, to compare the two and identify the correlations which would form the mechanisms for any long term operational service to the fishing industry.

The Norfolk Island domestic fishery survey was undertaken by Department of Primary Industry (DPI), Canberra on behalf of the Norfolk Island Legislative Assembly. Research undertaken on Norfolk Island during 1981 to 1983 was funded by the Fishing Industry Research Trust Account (FIRTA 81/49) with contributions from DPI for computing and research design, and the Norfolk Island Government for subsidized accommodation, transport and laboratory facilities.

The program followed consultation between the Norfolk Island Fishing Club, the Norfolk Island Legislative Assembly, the Department of Territories and DPI, Canberra in response to complaints from local fisherman that fish stocks were declining. Local fishermen considered that foreign fishing vessels (FFV's) in Norfolk Island waters had depleted continental shelf demersal fish stocks.

Information is presented here indicating that the decline in fish abundance in Norfolk Island waters is a normal response to increased fishing pressure from the growing domestic fishery. Furthermore, it is believed that the Norfolk Island continental shelf demersal fishery is approaching full exploitation.

The program was designed to provide a baseline for future fisheries management.

The program was designed to provide a baseline for future fisheries management.

The Norfolk Island domestic fishery survey was undertaken by Department of Primary Industry (DPI), Canberra on behalf of the Norfolk Island Legislative Assembly. Research undertaken on Norfolk Island during 1981 to 1983 was funded by the Fishing Industry Research Trust Account (FIRTA 81/49) with contributions from DPI for computing and research design, and the Norfolk Island Government for subsidized accommodation, transport and laboratory facilities.

The program followed consultation between the Norfolk Island Fishing Club, the Norfolk Island Legislative Assembly, the Department of Territories and DPI, Canberra in response to complaints from local fisherman that fish stocks were declining. Local fishermen considered that foreign fishing vessels (FFV's) in Norfolk Island waters had depleted continental shelf demersal fish stocks.

Information is presented here indicating that the decline in fish abundance in Norfolk Island waters is a normal response to increased fishing pressure from the growing domestic fishery. Furthermore, it is believed that the Norfolk Island continental shelf demersal fishery is approaching full exploitation.

The program was designed to provide a baseline for future fisheries management.

Since the spread of common carp into South Australia in the early 1970's, they have remained abundant in the River Murray and the lower lakes. With the continued high catch rates, there has been concern as to the effects carp may have on the environment and on native fish. This impact will be determined largely by the feeding habits of carp. Although carp are recognized as the most widely distributed freshwater fish, very little is known of their ecology in natural environments. overseas studies have suggested that carp feed by 'roiling' the mud and selecting food particles from the suspended matter. This study aimed to determine the diet of carp in Lake Alexandrina and to make inferences on the environmental effects carp may produce.
