Fisheries Queensland. Freshwater fish stocking | Recreation, sport and arts | Queensland Government. Freshwater fish stocking in Queensland is the process of releasing young fish (fingerlings) into dams, weirs and rivers to enhance and maintain fisheries, provide mosquito control and assist threatened fish species to recover. Fish are stocked in Queensland public waters by approximately 70 community-based fish stocking groups that have stocking permits. The Stocked Impoundment Permit (SIP) scheme provides funding for stocking groups at 32 dams in Queensland.
Fish stocking groups also raise funds in the community to stock non-SIP dams, weirs and rivers. Impounded waters such as dams need to be continually restocked because, in most circumstances, stocked species will not reproduce there. Most of the popular dam fisheries in Queensland are stocked each year with fingerlings to ensure the fishery remains successful into the future.
Stocking your own dam When choosing species to introduce it is best to check which drainage division your region is classified under. Recreational fishing | Recreation, sport and arts | Queensland Government. Stonefish - Queensland Museum. Stonefish are the most venomous of all fishes. They are found throughout shallow coastal waters of the northern half of Australia. The fish usually lies motionless, often partially buried in the substrate and perfectly camouflaged among surrounding coral, rocky reef, rubble, or aquatic plants. The stonefish has 13 sharp strong dorsal fin spines that are contained within a sheath of thick skin. At the base of each spine there are two venom glands that discharge their contents along ducts in the spine. When disturbed, the fish erects its spines, but maintains its position on the sea floor. Stings usually occur to the feet of swimmers or waders who have ventured away from clean sandy substrate and closer to the more complex bottom structure preferred by the stonefish.
Multiple spines can often penetrate affected limbs, resulting in more extensive envenomation. Photo: Ian Banks Total length to 47 cm, common to 28 cm. Freshwater fishes - Queensland Museum. Australia has a highly diverse marine fish fauna, however the number of freshwater species is relatively few for such a large continent. The arid climate and inconsistent rainfall throughout much of the country has not provided for the development of extensive or complex freshwater systems.
Freshwater environments are largely restricted to the coastal fringe of the north and east of Australia. These are the areas that have the most diverse freshwater fish communities. About 300 species of native and foreign introduced freshwater fishes occur in Australia. Most of these were recently derived from marine ancestors. Many of the 30 introduced species have established permanent breeding populations.
The attached list of fishes (183 KB) includes all species that may be found in freshwater throughout Queensland.

It’s a funny old game you know – it’s the single most popular hobby, sport and pastime in the world… by a long shot. Every day people head out to ponds, rivers, lakes and oceans for pleasure, sport or survival to hook, net or spear a fish.
And everyone remembers their first fish. Mine came on a family holiday in the east of England, a 2.2lb European chub. Not a big fish by a long shot, but hugely memorable when you’re eight years old. I still remember the snatch on the line, the accelerated heart beat (mine), the game of tug and war that went on until finally the invisible force materialised as a splash on the water’s surface. I’ve never been good at it but, from the first, I was hooked! Dotted throughout Queensland are stunning inland lakes, lots of them – and where there’s water, there’s usually fish. Our first stop is near the town of Gin Gin. We arrive at Lake Monduran, the first of our freshwater locations, as the eastern horizon is turning tangerine.
Until then, Ben. Animal species fish. Declared fish habitat areas (Department of National Parks, Sport and Racing) A declared fish habitat area (FHA) is an area protected against physical disturbance from coastal development, while still allowing legal fishing. Queensland's FHA network ensures fishing for the future by protecting all inshore and estuarine fish habitats (e.g. vegetation, sand bars and rocky headlands) contained within declared FHAs, which play the key role of sustaining local and regional fisheries.
List of Fish Species -- Fish Photos. NSW fish species. Identifying Fishes - Fishes of Australia. Fishes can be hard to identify. They range in size from tiny gobies less than a centimetre in length to the enormous whale shark. Not only do they come in wide variety of shapes and colours, males and females often differ, and juveniles may appear very different from adults of the same species. Fishes have many features that aid fish identification including · Body shape · The number, shape and position of the fins · Fin ray counts · Head length · Snout length and shape · Eye size · Specific markings such as spots and stripes · Scales – yes/no, small/large?
Fishes can be identified by looking at lots of images, or you can use a variety of identification aids known as keys. We have developed two interactive keys to assist you with your identifications. The first is a simple FISH FAMILY FINDER which will enable you to work out what kind of fish you have. Author: Dianne J. Bag and size limits - saltwater.
Bag limit: The maximum number of fish or invertebrates per person per day. A maximum daily bag limit of 20 applies to any fish or invertebrate not included in the tables below. Protected and threatened species cannot be taken. * Bag limit comprised of any single species or a combination of listed grouped species. Possession limit: The maximum number of fish a person is allowed to have in their possession at any one time. For all saltwater species except; Australian Bass and Estuary Perch, Flathead (except Dusky), Bream and Tarwhine, Tailor, Luderick, Trevallies and Blue Swimmer Crab, the daily bag limit is also the possession limit. Finfish Bag and Size limits Invertebrates Bag and Size limits + All lobsters, crabs, bugs and crayfish carrying eggs must be returned to the water.

The extent of overfishing The global fishing fleet is 2.5 times larger than what the oceans can sustainably support – meaning that humans take far more fish from the ocean than can be replaced naturally. As a result: 24% of fish species are overexploited, depleted, or recovering from depletion 52% of the world’s fisheries are fully exploited and have no ability to produce greater harvests several important commercial fish populations have declined to the point that their survival is threatened.Factors contributing to overfishing It is through poor or no management, not a lack of awareness, that overfishing continues. Contributing factors to the current level of overfishing include: As coastal and pelagic (open ocean) fisheries around the world have declined, fishing effort has shifted to the deep sea and previously unexploited fish species.
Here, overfishing can quickly deplete local fish populations, even during a single season. Mangroves of Australia. Animals of the mangroves There are at least 70 different species of Crustaceans in Australian mangroves, of which about 65 percent are crabs and the rest prawns and shrimps. Over 70 species of fish are known from Australian mangrove creeks and rivers, most spending at least some part of their lifecycle in that protective environment. Mudskippers are one of the few fish which live only on tropical mangrove shores.
At least 100 species of molluscs are found in Australian mangroves. About 75 percent of these are gastropods (snails) which feed on microscopic plants the remainder being bivalves. The best-known of these is probably the mangrove oyster which colonises the trunks and aerial roots of the trees in large colonies. Mud Lobster are believed to eat tiny pieces of organic matter in the mud. At least 24 species of polychaete worms are known to live in the mangrove mud. Insects are the most diverse and numerous of all animal groups in the mangroves. Fishnet | The Fish Files. Ocean Fish Pictures. Australia's Biodiversity - A Summary | The Wilderness Society. Australia - the only country in the world which spans an entire continent and its biota - has an unparalleled opportunity for conserving a significant part of the world's biodiversity.
Australia is the only megadiversity nation on Earth which is a developed nation with a low population density - the only country in the world with a high level of economic ability for biodiversity protection, without the population pressures that could compete with biodiversity protection for land use. We have more species of higher (vascular) plants than 94% of countries on Earth, and more non-fish vertebrate animals (mammals, birds, reptiles and amphibians) than 95% of the world's countries.
We have more species of mammals than 93% of countries, more birds than 79% of countries, more amphibians than 95% of countries, and more reptiles than any other country on Earth. Even more telling are the number of endemic species in Australia - species which occur nowhere else on Earth. Beattie, A.J. (ed.) 1995. Home.
