Australia's largest fish is the Murray Cod (Maccullochella peelii), a massive freshwater species native to the Murray-Darling Basin that can exceed 1.8 meters (6 feet) in length and weigh over 100 kilograms (220 lbs). Despite its name, it's not a true cod but an iconic apex predator crucial to its ecosystem and Indigenous culture.
The Murray Cod is Australia's largest freshwater fish. The biggest recorded was 1.8 m long and weighed 113 kg! The cod's size depends on its habitat, with those living in smaller waterways reaching at least 60 cm and between 3 kg to 4 kg. In larger waterways they grow to 100 cm or more and weigh up to 20 kg.
The calculations confirmed that Australia's longest single river is the River Murray at 2508 kilometres. However, if the longest tributaries of the Darling River, the Culgoa, Balonne and Condamine, are taken into account its total length increases to 2740 kilometres, making it Australia's longest waterway.
The "Big 5 fish" typically refers to the five most popular seafood species consumed in the UK: cod, haddock, salmon, tuna, and prawns, which make up about 80% of sales and consumption. However, the term can also refer to different concepts, like Australia's marine "Big 5" (whale sharks, humpbacks, manta rays, turtles, dugongs) for eco-tourism or a list of apex predators like large sharks in documentaries.
Barracuda. Known for their speed and sharp teeth, barracudas can be aggressive and have been known to attack humans, causing severe injuries - however it is thought that attacks are because it mistakes humans for a fish caught on spear.
The Dietary Guidelines for Americans states that to consume those higher amounts, children should only be fed fish from the “Best Choices” list that are even lower in mercury – these fish are anchovies, Atlantic mackerel, catfish, clams, crab, crawfish, flounder, haddock, mullet, oysters, plaice, pollock, salmon, ...
The Murray River, The Murray, Victoria, Australia.
Yes, bull sharks can enter the Murray River and have been sighted, especially near the mouth and in brackish lower sections like the Lower Lakes, as they tolerate fresh and saltwater, but they aren't common residents far upstream; they venture into rivers seeking food and often retreat to saltwater, though older reports suggest sightings much further inland before barrages were built, notes this Facebook discussion.
Where does the Congo river flow through? The Congo is the deepest river in the world. Its headwaters are in the north-east of Zambia, between Lake Tanganyika and Lake Nyasa (Malawi), 1760 metres above sea level; it flows into the Atlantic Ocean.
Greenland sharks are the longest-living vertebrates in the world. The oldest known individuals recorded by scientists have been about 400 years old, though with the large margin of error, it's possible that they could live for more than 500 years.
Salmon is widely recognised as the King of Fishes because of its strength, endurance and unique life cycle. Read why salmon is known as the King of Fishes, its migration strength, characteristics, nutritional value and importance.
Now, a groundbreaking study has revealed shocking new details about orcas hunting one of the ocean's most massive creatures—the whale shark. These apex predators have developed a specialized technique to target and kill the world's largest fish, and the findings might change what we know about orca behavior.
There's no single "best" fish, but top contenders for taste in Australia include Coral Trout, Barramundi, Snapper, King George Whiting, and Blue-Eye Trevalla, praised for their sweet, firm, white flesh, while Dhufish, Golden Snapper (Fingermark Bream), and Mangrove Jack are also highly rated for their delectable flavour and versatility, with many suggesting simpler preparations highlight their natural taste.
Remains of megalodon fossils have been found across Europe, Africa, the United States of America and Australia, suggesting that the species occupied all of the oceans, except for polar areas.
The biggest great white sharks can reach up to 20 feet long, but most are smaller. The average female is 15-16 feet long, while males reach 11-13 feet.
Brent Lodge pulled the dead freshwater crocodile out of the Murray River near the NSW-Victoria border. It had a hook in its mouth and had been partly skinned.
The most dangerous sharks in Australia, responsible for the majority of attacks, are the Great White, Tiger Shark, and Bull Shark, with the Bull Shark often cited as the most dangerous due to its aggressive nature, wide habitat (including freshwater rivers), and tendency to frequent shallow, populated coastal areas where humans swim. The Tiger Shark is also highly dangerous due to its large size and indiscriminate diet, while the Great White is notorious for its power and frequency in attacks.
To tell if a shark is near, watch for nature's signs like diving birds or agitated fish, notice unusual shadows or fins, and be aware of areas with fishing activity, but most importantly, listen to lifeguard warnings, avoid murky water, and observe sharks' behavior for signs of excitement or erratic movements, indicating you should calmly leave the water.
The river descends 1,070 metres (3,510 ft) over its 225-kilometre (140 mi) course. When at maximum capacity, the Broken River is the fastest flowing river in Australia. The town of Benalla, located adjacent to the river, was known as Broken River into the 1850s.
The total area of Australia waters is 8 914 134 km2 (Table 1). Of which, 70.4% is deep sea >1000 m (6 271 160 km2), 48% is deeper than the 3000-m abyssal boundary (4 246 601 km2), and 0.2% is hadal (>6000 m; 15 038 km2; Table 1).
Australia's only permanent river system is the Murray–Darling Basin, with the Murray River as its main stream, flowing from the Australian Alps through southeastern Australia to the Southern Ocean, providing vital water for irrigation and homes across three states. While many Australian rivers are ephemeral (seasonal), the Murray-Darling system is the continent's most significant and consistently flowing water source, supporting a vast, arid region.
The unhealthiest fish to eat are typically large, predatory species high in mercury like shark, swordfish, king mackerel, and imported tilefish, plus bluefin tuna, which are dangerous for brain/nerve health, especially for pregnant women and children; also, farmed salmon and some imported tilapia/catfish raise concerns for contaminants and antibiotics, while orange roughy and Atlantic cod are often cited for high mercury and overfishing/sustainability issues.
Oily fish – such as salmon and sardines – is also particularly high in long-chain omega-3 fatty acids, which can help to keep your heart healthy. Most of us should have more fish in our diet, including more oily fish. There is different advice for women who are pregnant or breastfeeding, and children and babies.
They are especially rich in selenium. Although both have enough Vitamin B12 to cover the daily need, sardines contain 3 times more of it than salmon. On the other hand, compared to sardines, salmon is richer in Vitamin D, as well as other B-complex vitamins such as Vitamins B3, B6, and B5.
