Fisheries Queensland. Freshwater fish stocking. 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. Recreation, sport and arts. 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. To prevent stonefish stings, sturdy footwear should be worn on reef flats, or while wading on soft-bottom substrates adjacent to rocky or weedy areas.

Australia has a highly diverse marine fish fauna, however the number of freshwater species is relatively few for such a large continent.
Fishing around Queensland... Fishing.
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. 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. 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. Bag and size limits - saltwater.
Overfishing – the plundering of our oceans. 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: Mangroves of Australia. The Fish Files. Ocean Fish Pictures. Australia's Biodiversity - A Summary. 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. Kennedy, M. Home.
