The Australian bass is a native predatory fish species commonly found in coastal rivers and streams along the east coast of Australia. It is a popular game fish among anglers and is known for its aggressive feeding habits, consuming anything within range, including golden shiners, shad, crawfish, salamanders, and various insects and worms. In the wild, their diet consists mostly of aquatic invertebrates and insects that fall onto the water surface, such as yabbies, shrimp, grasshoppers, and cicadas. In captivity, they can be fed live feeder fish, but their diet should be supplemented with insects and worms.

| Diet in freshwater | Insects falling onto the water surface, and a variety of organisms living on or near the bottom such as insects, crustaceans, tadpoles, and small fish |
| Food preference | Golden shiners, shad, crawfish, and salamanders |

What You'll Learn
Australian bass are not picky eaters
In the wild, Australian bass inhabit mostly deep rivers and estuaries. They are strong swimmers and can easily traverse rapids and fast-flowing water. At night, they display pelagic ("near-surface") behaviour and actively hunt prey in shallow water and at the water's surface. They are known to be aggressive and will feed until the food is hanging out of their mouths. They are also known to gorge themselves in preparation for the winter months.
The Australian bass is a small-to-medium-sized species of primarily freshwater fish found in coastal rivers and streams along the east coast of Australia. They are an important member of the native fish assemblages found in east coast river systems and are a very popular game fish species among anglers. They are closely related and similar in appearance to estuary perch but can be differentiated by white edges on their anal and pelvic fins and a relatively smaller mouth.
In terms of diet, Australian bass are known to be adaptable. While they may have preferences for certain foods, such as golden shiners, shad, crawfish, and salamanders, they will primarily eat what is available in their habitat. This includes a variety of live foods, such as insects like grasshoppers, cicadas, and worms, as well as aquatic invertebrates such as yabbies and shrimp. They are also known to eat pellets formulated for large predators.

They eat insects, crustaceans, worms, and small fish
Australian bass are not picky eaters. They are carnivorous and have a varied diet, including insects, crustaceans, worms, and small fish. They are native predatory fish and are extremely popular among anglers.
In estuaries, Australian bass feed on shrimps, insects, worms, and smaller fishes. They are known to eat aquatic insects, such as beetles and moths, and earthworms, including scrub worms. They also eat freshwater shrimp and small yabbies. In freshwater, they feed on insects that fall onto the water surface and other organisms living on or near the bottom, such as crustaceans, tadpoles, and small fish.
The stomachs of Australian bass found in Gippsland contained mostly shrimp and prawns, with some fish remains and aquatic insects. They are known to gorge themselves in preparation for the winter months, eating leeches, worms, and crayfish.
Australian bass food preferences change with the season and the relative abundance of minnows and other common baitfish, insects, and worms. They have been described as binge feeders, eating anything that comes within range until the food is hanging out of their mouths. They are strong swimmers and can easily traverse rapids and fast-flowing water, making them well-adapted to hunting in shallow water and at the water's surface at night.

They are predatory and eat live fish
The Australian bass is a predatory fish species with a varied diet. They are known to eat live fish, with small fish constituting a very small percentage of what a wild bass would eat. They are often fed live feeder fish in captivity, but this is not their primary food source in the wild.
In the wild, Australian bass are likely to encounter and eat a variety of organisms from the water's surface, including aquatic insects, shrimps, and other freshwater crustaceans, tadpoles, and small fish. They are opportunistic feeders and will eat anything that comes within range. They have been described as binge feeders, eating until their mouths are full, and then relaxing until they are hungry again.
The diet of Australian bass changes with the season and the relative abundance of different food sources. For example, during the winter months, they may gorge on certain foods to prepare for the leaner months ahead. Australian bass are also known to feed at night, displaying pelagic ("near-surface") behaviour as they actively hunt prey in shallow water and at the water's surface.
Australian bass are strong swimmers and can easily traverse rapids and fast-flowing water. They use their strength and agility to their advantage when hunting and can be found near sunken logs, river banks, and even in open water as they seek out prey. They are not picky eaters, and anglers have reported success in catching them with various types of bait and lures.

They eat aquatic invertebrates like shrimp and yabbies
The Australian bass is a native predatory fish and an extremely popular game fish species among anglers. It is carnivorous, and its diet consists of a variety of aquatic invertebrates and insects. Over 50% of its diet is made up of invertebrates such as shrimp and yabbies, as well as insects that fall on the water surface, like grasshoppers and cicadas. Bass will also eat worms, which are a less likely food source but are still nutritious.
In estuaries, Australian bass feed mainly on shrimp, insects, worms, and smaller fish. They also eat a variety of organisms living on or near the bottom, such as crustaceans, tadpoles, and small fish. In freshwater, they will feed on insects that fall onto the water surface. Bass are not picky eaters and will eat almost anything that comes within range. They are known to be binge feeders and will feed until their mouths are full.
The diet of Australian bass in the wild is supplemented with live food, such as insects like beetles and moths, earthworms, and freshwater shrimp and small yabbies. Bass can be trained to take fish strips from the hand, but their diet should be mostly made up of live food to mimic their natural diet.
The food preferences of Australian bass change with the season and the relative abundance of different food sources. For example, largemouth bass in creeks and streams will gorge themselves in preparation for the winter months, eating leeches, worms, and crayfish. Australian bass are strong swimmers and can easily traverse rapids and fast-flowing water, giving them access to a variety of food sources.

They adapt to the food available in their habitat
The Australian bass is a native predatory fish and an extremely popular game fish species among anglers. It is a small-to-medium-sized species of primarily freshwater fish found in coastal rivers and streams along the east coast of Australia.
Australian bass are not picky eaters and will adapt to the food available in their habitat. They have a varied diet, including insects from the water's surface and other organisms from the entire water column and the bottom, including aquatic insects, crustaceans, tadpoles, and small fish. In estuaries, they mainly feed on shrimps, insects, worms, and smaller fish. In freshwater, they will feed on insects falling onto the water surface, such as grasshoppers, cicadas, moths, and beetles, and other organisms living on or near the bottom, such as crustaceans, tadpoles, and small fish.
The stomachs of Australian bass in Gippsland, Victoria, were found to contain mostly shrimp and prawns, with smaller amounts of fish remains and aquatic insects. This adaptability to their environment and varied diet likely contribute to their popularity as a game fish species.
Additionally, Australian bass food preferences change with the season and the relative abundance of certain prey items. For example, largemouth bass in creeks and streams will gorge themselves in preparation for the winter months, feeding on leeches, worms, and crayfish. They are also known to be binge feeders, eating anything that comes within range until they are full. This adaptability to the food available in their habitat allows them to take advantage of the most abundant food sources at any given time.
