Australian sea lions are found nowhere else on earth. But they were being caught in high numbers in gillnet fisheries off the South and Western Australian coastlines. With the support of the Australian public and working with our conservation colleagues, we secured protection for these much loved and vulnerable animals. Books at Amazon.

In May, Harcourt was a co-author of a study that analysed data on the whereabouts of bull sharks, using commercial fishing catch data and information . cuvier catch-rates in the Eastern Gulf of Shark Bay, Western Australia were consistently greater during the warm season (September-May), when surface water temperature was greater than 20°C, than during the colder months (June-August). In Sydney Harbour, water temperature also appeared to influence the rate of capture of C.
Australian Anchovies are pelagic schooling fishes found in depths from metres. The species mostly occurs in bays, inlets and estuaries, also adults are also found in offshore waters. Feeding. Feeds on zooplankton in the water column. Fisheries. Australian Anchovies are of minor commercial importance and are used as bait. Author. Dianne J. Study site and acoustic array. The study was conducted in the Georges River, in the southern Sydney metropolitan area (°S, °E). The river is 96 km long and drains a catchment of km 2, with the upper limit to the estuary being the Liverpool Weir 45 km Georges River estuary is primarily urbanised,, and has experienced substantial shoreline modification and heavy.

Much of the following history is drawn from The Commercial Fisheries of Temperate Western Australian Estuaries: Early Settlement toRCJ Lenanton, Western Australia’s estuaries have been fished for as long as there has been human habitation near them.
Between and96 species of finfish, 7 species of crustaceans and 12 species of mollusks contributed to the large commercial fishery in estuaries, protected coastal areas and open marine waters of temperate Western Australia.

This is a list of aquatic animals that are harvested commercially in the greatest amounts, listed in order of tonnage per year () by the Food and Agriculture s listed here have an annual tonnage in excess of 1, tonnes.
This table includes mainly fish, but also listed are crabs, shrimp, squid, bivalves, and a soft shell turtle. Commercial fishermen in Western Australia are pro- Catches are obtained either by locating and then hauling vided by the State Government with return books in schools of fish with nets or by setting unattended gill nets which the daily and monthly summaries of their catch overnight in areas where fish are likely to be caught, and effort have to be recorded.
The estuaries of Western Australia (also known as the Inlets of Western Australia) are located along the coastline of Western Australia. The coastline can be considered in three main sections: south, west, and estuarine features carry through all three regions.
Wetlands and estuaries of the south west region have very similar ecologies and occurrences of biota. Lenanton and Potter () estimated that in temperate Western Australia, estuarine opportunist commercial fisheries were worth $m per annum 7.
In Western Australia, these fisheries include Cobbler, Sea Mullet, Yelloweye Mullet, Australian Herring, Australian Salmon and Whiting. In these fisheries are estimated to have been worth.
Characteristics of the ichthyofaunas of south-western Australian estuaries, including comparisons with holarctic estuaries and estuaries elsewhere in temperate Australia: a review.
Australian Journal of Ecol – The rivers of south-western Australia and south-eastern Africa lie at similar latitudes, open into the Indian Ocean and frequently have estuaries that are periodically closed off from the sea by sand bars at their mouths.
The present study has compared the species, genera and families represented in the fish assemblages of estuaries in south-western Australia and temperate southern Africa, i.e.

Estuaries are especially vulnerable to the impacts of climate change because changes in climatic and hydrologic variables that influence freshwater and marine systems will also affect estuaries.
We review potential impacts of climate change on Australian estuaries and their fish. Geographic differences are likely because southern Australian climates are predicted to become warmer and drier.
Regional Estuaries Initiative. The Regional Estuaries Initiative is a four-year, $20 million Royalties for Regions funded program to improve the health of six Western Australian estuaries.
This is the biggest single investment that the state government has made in managing Western Australia’s regional estuaries. This book brings together, for the first time, a series of experts in various aspects of the eutrophication of shallow estuaries. It provides a comprehensive picture of our current state of knowledge of these systems.
The first half of the book contains case studies from Asia, Australia, Europe, and South Africa and covers both temperate and tropical waters. The second half contains chapters. Australia’s Commonwealth, state and territory governments manage fisheries in consultation with the fishing industry, scientists, economists and other user groups, such as those that represent traditional fishing, recreational fishing and environmental non-government organisations.

The Australian coastline extends approximately 34 kilometres (excluding all small offshore islands) and includes more than estuaries. Approximately 50 per cent of the Australian population resides within seven kilometres of the coast and ports and other coastal infrastructure are pivotal in supporting primary industries and tourism.
