Yellowfin Whiting (Sand Whiting)
Shore / EstuaryYellowfin whiting — also called sand whiting in WA — are an excellent-eating fish of sandy shallows and estuary flats. Often caught alongside King George whiting; target them with light tackle and worm or prawn bait.
Overview
Yellowfin whiting are a reliable year-round target on Perth's sandy shallows and estuary flats. While they don't have quite the same prestige as King George whiting, they're excellent eating and often more willing to bite. A great species for a relaxed session with light tackle.
Identification
Sand whiting, western sand whiting, yellowfin
Plain silvery-white with a pale olive back, no spots and no lateral stripe — the giveaway is the yellow wash through the pelvic and anal fins that gives the fish its name. Slim pointed head and a small underslung mouth for working the sand. It's most often confused with western school whiting, which carries a dusky mid-body stripe and stays smaller, and with juvenile King George whiting, which are covered in rows of brown spots. On the flats the shorthand holds: spots means KG, stripe means school whiting, plain silver with yellow fins means yellowfin.
How to Catch
Tube worms, beach worms, prawns, yabbies (nippers)
N/A — bait-only species. Occasionally taken on very small soft plastics but bait is the way to go.
Running sinker rig with a size 4–6 long-shank hook and a small ball sinker. Use light fluorocarbon leader (4–6lb). The lighter the rig, the more bites you'll get.
Fish sandy shallows and estuary flats with light tackle and fresh bait. Cast into gutters and depressions where whiting feed, and be ready for a subtle bite. Like KGs, yellowfin whiting are gentle biters — keep the rod in hand and feel for the tap. Walk the beach and fan-cast to find fish rather than sitting in one spot.
Bite throughout the day, with peaks around dawn and dusk. Rising tide over sandy flats is ideal. They're active year-round but fishing can be easier in the warmer months when they're on the shallow flats.
Up to 1.5kg, commonly 300–600g
Year-round
Size & Growth
A typical flats fish is 25–32 cm and 250–450 g. A good yellowfin is over 35 cm and around 600 g, and a 40 cm-plus fish is genuinely big — the 1.5 kg headline size is exceptional. They're moderately long-lived, more than a decade for a big fish, and slow down considerably once mature. There's no legal minimum size, so it's on you to put back anything too small to bother cleaning; under about 25 cm they're barely a mouthful. The Peel-Harvey and the Swan flats tend to produce a bigger average fish than the open beaches.
Diet & Habitat
Yellowfin whiting eat marine worms, nippers (yabbies), small crabs, shrimp and bivalves, hoovering the sand in ankle-to-knee-deep water. They favour warm, shallow, sheltered sandflats and estuary basins — often so shallow you'll see tails and wakes on a calm morning — and drop back into the adjacent gutters as the tide falls. In WA they're found from about Shark Bay down to the south coast, with the Peel-Harvey, Leschenault, Mangles Bay and the sandy shallows of the Swan the standouts. Warmer months push them right up onto the flats; in winter they sit deeper in the channels and are harder to find.
WA Size & Bag Limits
| Minimum size | No minimum size |
|---|---|
| Bag limit | 30 per whiting species (excluding King George whiting) |
| Counts toward | Whiting sit in the statewide "all other species of finfish" category, whose TOTAL mixed daily bag is 30 — shared with herring, garfish and mullet. So 30 is also the practical ceiling across the whiting group. |
No minimum size. Daily bag limit: 30 per individual whiting species excluding King George (Family Sillaginidae) — the limit applies to each species in the group. All of them then count within the statewide "all other species of finfish" TOTAL mixed daily bag of 30, which is shared with Australian herring, garfish and mullet, so 30 is the practical ceiling across the whole group rather than 30 of each on top of one another.
Eating Quality
Excellent eating — very close to King George whiting and, on a decent-sized fish, hard to tell apart on the plate. Sweet, mild, fine-flaked white flesh with no bloodline and very little fishiness. Smaller fish are best scaled, gutted and pan-fried whole; anything over about 30 cm fillets cleanly and is worth the knife work. Dust in seasoned flour and fry in butter, or crumb and deep-fry — they're the classic fish-and-chips whiting. Because they come out of warm shallow water they go off faster than you'd expect, so get them on ice and eat them within a day or two. They freeze passably if skinned, portioned and vac-sealed, but the texture softens and the sweetness fades, and fresh is the whole point of the species.
Perth Tips
Palm Beach, Mangles Bay, and the shallows inside the Dawesville Cut are good spots. Prawns or beach worms are your best bait. A long rod (10ft+) helps with casting distance on the flats.
