What You'll Learn
Australian snapper are carnivorous
Snapper are a sought-after species for recreational fishers in Australia, and they are also prized for their taste and texture as an edible fish. The species is found in coastal waters around the southern half of Australia, particularly in Western Australia, South Australia, Victoria, Queensland, and New South Wales. They are also found in smaller numbers off the coast of Tasmania.
The size and maturity of snapper vary across Australia, with females in Perth, WA, reaching maturity at approximately 58 cm and 5 to 6 years of age. During the spawning season, snapper can form large aggregations consisting of thousands of fish. The legal size limits for snapper vary by state, with Queensland having a minimum size of 35 cm and Western Australia requiring a minimum of 50 cm.
Snapper fishing in Australia requires knowledge of the local regulations, as there are bans and tight restrictions on when and where snapper can be fished in some states. Anglers are advised to release immature fish to maintain breeding stock and are encouraged to consider the slow growth rate of this species. Snapper aquaculture has become an important industry in recent years, with farmed fish exposed to more sunlight, resulting in darker colouration.

They eat crustaceans, molluscs, and worms
The Australasian snapper, or silver seabream, is a carnivorous species of porgie native to the coastal waters of Australia, New Zealand, the Philippines, Indonesia, mainland China, Taiwan, and Japan. They are highly prized as edible fish, known for their sweet sea taste and firm texture.
Snapper feed on a variety of organisms, including crustaceans, molluscs, and worms. They are adaptable and will quickly change their feeding habits if their primary food source becomes scarce, allowing them to target alternative prey. This makes them effective hunters, and they will eat most things in the sea, including smaller fish.
Crustaceans, such as crabs, shrimp, and lobsters, are a favoured food of snapper. They provide a good source of protein and nutrients for the fish, and their hard shells can help keep the snapper's teeth sharp. Molluscs, including mussels, clams, and squid, are also a part of the snapper's diet. These soft-bodied animals provide a good source of protein and are relatively easy for the snapper to catch.
Worms, such as sea worms and marine night crawlers, are another important food source for snapper. They are a rich source of protein and fatty acids, which can be beneficial for the fish's health and development. Additionally, worms can be found in a variety of marine habitats, making them readily available to snapper.
The diet of snapper can vary depending on the availability of food sources and the location. They are opportunistic feeders and will take advantage of whatever prey is most abundant in their environment. This adaptability allows them to thrive in a range of habitats and ensures their survival in changing ecological conditions.

They also eat smaller fish, urchins, jellyfish, and algae
The Australasian snapper, or silver seabream, is a carnivorous species of porgy found in the coastal waters of Australia, the Philippines, Indonesia, mainland China, Taiwan, Japan, and New Zealand. They are highly prized as edible fish and are popular among recreational fishers.
Snapper feed on a wide range of organisms, including crustaceans, molluscs, worms, and sea worms. They also eat smaller fish, urchins, jellyfish, and algae. Their diet consists of most things in the sea, and they are known for their adaptability. If one food source becomes scarce, they can quickly change their feeding habits to target different prey.
In terms of size, snapper can grow to around 1.3 metres in length and weigh at least 20 kilograms. They are usually pinkish to brown on their upper sides and silvery below. The body is covered in small bright blue spots, which are more obvious in smaller fish.
Snapper are found in the southern waters of Australia, from southern Queensland to the central coast of Western Australia. They are known to live in rocky areas and reefs at depths of up to 200 metres. They tend to school and migrate between reefs. Larger snapper are often found in estuaries and harbours, such as Port Phillip Bay, which is known for its seasonal snapper run.
The species is long-lived, with a lifespan of around 40 years in the wild. They reach sexual maturity at about 30 centimetres long, and a small percentage of males turn into females at puberty. Large individuals of both sexes develop a prominent hump on their heads.

They adapt their diet when food sources are scarce
The Australasian snapper, or silver seabream (Pagrus auratus/Chrysophrys auratus), is a carnivorous species of fish. They are known to feed on a wide range of organisms, including crustaceans, molluscs, mussels, worms, urchins, jellyfish, and algae. They are also known to eat smaller fish.
Snapper are adaptable and opportunistic feeders. If their primary food source becomes scarce, they will quickly alter their feeding habits to target alternative prey. This ability to adapt their diet allows them to survive in various environments and ensures the survival of their species.
In Australia, snapper are found along the southern coast, particularly in the waters off New South Wales, Victoria, Queensland, and Western Australia. They are a popular target for recreational fishers and are highly prized for their taste and texture. The species is slow-growing and long-lived, with individuals capable of reaching 40 years of age.
The adaptability of snapper is particularly evident during their spawning season. Spawning takes a lot of energy, and some fish will stop eating during this period. Once spawning is over, the fish compensate by feeding aggressively to regain their strength. This is a critical period for their survival, and they may alter their diet and feeding behaviour to meet their nutritional needs.
The ability of Australian snapper to adapt their diet when food sources are scarce is a testament to their resilience and survival instincts. This behaviour ensures their longevity and contributes to their presence in various habitats across Australia's southern coastline.

They feed more during spawning season
Snapper are a carnivorous species and will eat most things in the sea, including worms, mussels, crustaceans, kina, and smaller fish. They are also known to eat urchins, jellyfish, and algae. Their adaptability is notable, as they can quickly alter their feeding habits if one food source becomes scarce, allowing them to target different prey.
During the spawning season, snapper can form large aggregations consisting of thousands of fish. This season varies by location; in warmer waters, it occurs between April and October, while in cooler waters, it takes place between October and December. Spawning takes a lot of energy, and many snapper will stop eating during this time. As a result, they become skinny and are often called "slabby" after the spawning period.
However, before and after the spawning season, the snapper feed more to build up their energy reserves. They move into shallower waters and feed aggressively to prepare for the energy-intensive spawning period. This increased feeding helps them restore their condition after spawning, which involves releasing multiple batches of eggs to ensure the survival of their species.
In Australia, the spawning season for snapper occurs in inshore waters, and they are found along the south coast, particularly near Kiama, Berry, Gerringong, Gerroa, Huskisson, Vincentia, and Shoalhaven. They inhabit rocky areas and reefs up to 200 meters deep and are known to migrate between reefs. Larger snapper, often called "old man snapper," may enter estuaries and harbours, such as Port Phillip Bay, which is known for its seasonal snapper run.
