As the name suggests, rubber sharks do not have sharp teeth, which makes them quite safe to handle. The posterior and upper part of the fish is gray in color with many small white spots. Sometimes rubber sharks can be almost black in color when taken from certain bodies of water. The underside is always white. The sex of a rubber shark can be determined by its external appearance. Male fish have a pair of appendages called claws, one at the base of each ventral fin. In sharks, measure from the posterior gill slit to the base of the caudal fin on each side of the body. They reach a size of up to ~1.9 m to 35 cm and females reach sexual maturity at the age of 5 years and 1.1 m in length. Litter sizes are typically around 14 puppies, but can also reach up to 57 puppies, and gestation periods include ~12 months, with a one-year reproductive cycle of rubber sharks caught on a range of baits, including pilchards, squid strips and legally sized mackerel, salmon and mullet fillets. Another very popular bait is eel portions or fillets. Some fishermen « cure » the eel by soaking it in brine beforehand.

Shark fishing in the metropolitan area is subject to restrictions on fishing gear. Fish, sharks and rays are very important marine resources and vital to the health of our marine ecosystems. We must all contribute to the fact that we will have fish, sharks and rays in the future. Rock lobster The last major rule change was in July 2017 for rock lobster, but details were not written down in the 2017 guide. It is required by law to mark your lobsters in stone. If possible, release the shark or skate while it is still in the water and cut the leash as close to the hook as possible. Revive the animal by running salt water over the gills, or if a shark is still in the water, move it back and forth. Use a soft, knotless net to land small sharks and rays. If you do not keep a shark or ray to eat, immediately put it back in the water. Southern fiddle rays often feed in sandy areas and seagrass beds – they feed on crustaceans (crabs, shrimp), small fish, molluscs and polychaete worms.
They crush hard-shelled prey such as crabs and mollusks with small blunt teeth in their powerful jaws. An education and awareness program will be conducted to inform fishermen about these new rules. Most large rubber sharks are caught at the southern end of Port Phillip Bay in areas such as the Coles Canal near St. Leonards, Mud Island, Queenscliff`s Simmons Canals and Sorrento Canal. At the central and northern ends of Port Philip Bay, rubber sharks are often caught in most areas where snapper can be expected. In the western port, they can be caught in various shallow places and deep water. A rubber shark with a little more legal minimum length can weigh about two kilograms. The majority of rubber sharks caught by anglers are estimated to be between 3 and 10 kilograms, with much larger specimens caught between 15 and 20 kilograms and more with increasing regularity in recent years. Many anglers choose to release these large fish unharmed, as they usually raise females. In sharks, measure from the posterior gill slit to the base of the caudal fin on both sides of the body. The ethical and humane treatment of sharks and rays is crucial for their survival and protection.
There have been some changes in different species in Port Phillip Bay, with the youngest focusing on rays, rays and banjo sharks. The community was concerned about the treatment of banjo sharks and rays, with evidence that they had been abused and injured on docks, piers and docks. Leave the shark or skate unharmed in the water as soon as possible. There are about 65 different species of sharks and rays in South Australia. As with all sharks, rays and chimaeras, the sexes are separated and fertilization takes place outdoors. Females give birth to litters of 2 to 5 puppies in autumn after a gestation period of 12 months. Puppies are born in teaspoons of 21-25 cm. Rubber sharks are an oceanic species known to travel long distances. They can be in a variety of water depths and can easily enter waters less than a meter deep in shallow bays and coastal beaches, especially under cover of darkness. They are often found in deep-water channels. body flattened with an oval to diamond-shaped disc; triangular muzzle short and wide; a row of large spiny teeth along the middle of the intervertebral disc to the first dorsal fin; Long, broad tail with two dorsal fins of similar size, upper tail lobe well developed, lower lobe short. Cheeks with lots of small blunt teeth.
A large damp cloth over the eyes of a shark or a disembarked ray keeps them cool and quiet. When catching and reintroducing sharks and rays, it is important to consider human safety as a top priority. Some of these animals are potentially dangerous. All sharks or rays that have not been caught for consumption must be returned to the water immediately. Simple handling instructions apply. Never lift a shark or shark by the tail. The poison in a raised beard is poisonous. Caught as bycatch while trawling in the Great Australian Bight. Southern fiddle rays are also caught in southeastern Australia in the Danish seine and hook and net fishery.
Catches are relatively low, and the species is usually thrown back alive and is thought to have a high survival rate after release. Large rubber sharks are very powerful. When fishing from a boat, a medium to heavy rod should be equipped with a coiled coil with a breaking load line of 8-15 kg. A heavier guide up to 1.5 meters long is completed by one or two 6/0 suicide hooks. The weight of the lead should be sufficient to keep the bait on the bottom in any stream. The best time to catch rubber sharks is at night, especially at rising tide, but they can also be caught during the day. Trout fishing On Saturday, September 2, 2017, updates on changes to trout fishing took place. These rule changes complement the current rules, these changes are as follows: If you fish and accidentally catch a ray or ray, put it back in the water as soon as possible without hurting or suffering. Ideally, store it in water to carefully remove the hook or cut the leash as close to the hook as possible. When catching a stingray, minimize handling and do your best to stay safe.
Do not place rays on hot, dry surfaces. If you need to bring the ray to a pier/pier, moisten the pier and put wet towels to help you.
