A number of Australian native fish are known as "PERCH".
Many of these fish are excellent table fish and are being grown in aquaculture facilities for use as table fish. A number of these species are now well established as premium aquaculture species in many countries. Australia has many, as yet untapped, freshwater fish which will also find themselves aquaculture favourites.
There is no doubt barramundi are one of the most popular and well known of Australia's sport fish. All barramundi are born as males. They spend the early part of their lives in fresh water until they reach sexual maturity. They then migrate down stream to the mouth of the river system where they meet the females, most of which have been living in the sea. They spawn in the salt water then some of the males will follow the females out to sea and some will go back to the river. The males which go out to sea will change to females. Even barramundi which are unable to go out to sea will still change into females.
You should think very carefully before stocking your farm dam with barramundi. Their demand for food is difficult to meet. They need a good supply of live food, such as small fish, shrimp, crayfish etc. They do not forage for food or eat aquatic vegetation. One of the biggest problems will be when you want to add more fingerlings to your dam. Any barramundi remaining from earlier stockings will make a meal of the new fingerlings, of any species, which you introduce to you dam. Barramundi are generally not suitable for small dams.
IMPORTANT NOTE: If you stock barramundi fingerlings into farm dams in Queensland, you MUST stock the correct genetic strain. There are a number of genetic strains of barramundi. It is a breach of the Queensland fisheries regulations to stock the incorrect strain. You should only purchase fingerlings from a hatchery operating within the fisheries regulations, and ask if the strain is the correct one for your district. Ausyfish Pty. Ltd. supply the "southern" strain.
Australian Bass are predatory fish and require sufficient natural food to thrive. This means a good amount of aquatic insects and other aquatic life such as shrimp, crayfish, small fish and frogs. Bass are usually difficult to convert to artificial food. For these reasons stocking rates in farm dams should be relatively low, about, 200-300 per hectare, and only if there is plenty of food. In an aquarium it is much easier to convert bass to artificial food, especially if you start them on frozen blood worms.
Bass are excellent eating. It is rare for Bass to have a muddy or weedy flavour.
Bass are easy to catch on live bait such as yabbies (lobbies), or lures. Since Bass are highly predatory, should you wish to add more fingerlings in later years, the older fish will often eat many of the new fingerlings.
