Identifying features

Sand flathead have a long and narrow body with a broad, flattened head. They are a sandy brown or mottled colour above and white below with occasional reddish brown spots along sides.

There may also be dark bands across the body and a distinctive black spot on the tail. Scales are present even though they are covered with a protective slime. The lower spine on the gill cover is longer than the upper spine.

Tiger flathead and bluespotted flathead can be commonly mistaken for sand flathead.

Sand flathead can be distinguished from tiger flathead by the teeth and tail markings. Sand flathead have flat, raspy teeth and a dark blotch on the lower part of the tail. Tiger flathead have large canine teeth and no dark markings on their tail.

Sand flathead can be distinguished from bluespotted flathead by the gillcover spines and tail-markings. On sand flathead, the lower gillcover spine is longer than the upper. On bluespotted flathead the spines are similar length. Sand flathead generally have one large dark blotch on the lower part of their tail, while bluespotted flathead have multiple black/brown spots surrounded by white.

Responsible fishing tips

Sand flathead stocks are depleted. You can help by:

Releasing flathead in good condition. Use circle hooks and a dehooker to return undersize flathead to the water.
Never using undersize flathead for bait.
Targeting a mixed bag of sustainable species like Australian salmon, mullet and mackerel.
Giving your sand flathead fish frames to the Tassie fish frame collection program .

Find out about the Flathead for the Future program.

If you catch a tagged flathead, record the details, including size of the fish and location caught, and report it to the Institute for Marine and Antarctic Studies

Detailed Rules

Bag limits

D'Entrecasteaux Channel, Derwent River, Frederick Henry and Norfolk Bays - 2
Eastern Zone - 5
Northern/Western Zone - 10

An overall bag limit of 20 applies for sand and tiger flathead combined.

Size limits

All waters (except King and Flinder's Islands) - Legal size between 35-40cm

King and Flinders Island - Minimum size 35cm, no maximum size

Possession limits

On land

On land (regardless of the zone/s you fished in) - 10

An overall possesion limit of 30 applies for sand and tiger flathead combined.

On State waters (on-water possession limit)

D'Entrecasteaux Channel, Derwent River, Frederick Henry and Norfolk Bays - 2
Eastern Zone - 5
Northern/Western Zone - 10

You cannot possess more sand flathead than the on-water possession limit of the zone you are in unless you are following the rules for moving between zones.

Moving between zones

When moving between zones:

All sand flathead must meet the size limit of the zone you are entering.
You cannot possess more sand flathead than the on-water possession limit of the zone you are in, unless you are following transiting rules.

Transiting

You can transit the D'Entrecasteaux Channel, Derwent River and Frederick Henry and Norfolk Bays in possession of a maximum of five sand flathead per fisher, so long as you travel directly to a boat ramp or landing point without stopping (unless required to for safety reasons).

Example: If you launched in the Derwent River, fished in Storm Bay and caught four sand flathead per fisher, you can bring these fish back to shore via the Derwent River so long as you travel directly to your point of landing without stopping.

This means you cannot stop to fish once in the D'Entrecasteaux Channel, Derwent River and Frederick Henry and Norfolk Bays Zone as at least one fisher is in possession of more than two sand flathead (exceeding the on-water possession limit of the zone)

More Information

Habitat

Sand flathead are a bottom dwelling fish usually found in inshore waters all around Tasmania. They prefer shallow waters of around 0-25 metres depth and a weed free, sandy bottom.

Fishing information

Sand flathead are the most commonly caught recreational species in Tasmania, accounting for two-thirds of all fish caught. They are present around the state and are relatively easy to catch. They can be caught on a variety of baits and lures providing they are fished close to a sandy bottom as they don’t usually rise more than one metre from the bottom to take a bait. Flathead are often caught from a boat that is drifting slowly so the fish see the bait as it passes by. May also be encountered at night when spearing for flounder.

Handling

Beware of short, sharp spines on the flathead’s gill covers and dorsal fin.

Public Health advice

The Director of Public Health advises people to limits meals of Derwent caught scalefish including flathead due to heavy metal contamination - refer to the Department of Health and Human Services or phone their hotline on 1800 671 738.

Cooking

Low oil content with a pleasant, sweet flavour. Fine textured flesh which can dry out slightly with some cooking methods but remains moist and flaky when cooked in batter. The long shape of flathead means that it fillets well as most of the bones are at the head section of the fish. Also retains moisture well when cooked as whole fish. Suitable to bake in foil, shallow or deep fry, marinate, poach or steam. Popular as fish and chips.

Recipe - Easy Cook Flatties:

2 flathead fillets; 2 tbsp rice or plain flour; salt and pepper; 2 tbsp olive oil.

Place flour and salt and pepper in a plastic bag. Place fish fillets into bag and shake bag. Remove fillets dust off excess flour. Heat oil in a large frypan to medium heat. Place fish into pan, cook for 3 minutes then turn over and cook for a further 2 minutes.

Recipe - Beer Battered Flathead:

500 grams flathead fillets; ½ cup flour; salt; 1 tbsp oil; ½ cup beer and 1 egg white; stiffly beaten.

Mix flour and salt, gradually add liquid and stir until smooth. Leave for 10-15 minutes. Gently fold in egg white. Dip flathead fillets lightly in flour before dipping in the batter. Heat oil to 180°C for deep frying or shallow fry in a wide pan.

Black spots in flathead fillets

Have you noticed black flesh or spots in your sand flathead fillets? This is a phenomenon known as melanisation which is the subject of research at the Institute for Marine and Antarctic Studies. Read about their Black Fillets Project research Report.
