Bronze Whaler
Surf / OffshoreThe bronze whaler — 'bronzie' — a powerful coastal shark caught right around the WA coast from the beach, rocks and boat. Bronze-flanked, fast and strong, it's a prime land-based-game target off the South West and lower west surf beaches and headlands. Taken on big baits, it tests heavy tackle to the limit. Handle with real caution — this is a large, dangerous animal.
Overview
Bronze whalers (Carcharhinus brachyurus) are the classic coastal shark of WA's beaches and headlands — heavy-shouldered, bronze-backed, and built for power. They range right around the WA coast, following bait schools and salmon runs into the surf zone, and they're the headline target for the state's land-based-game (LBG) anglers who fish big baits off South West and lower west beaches and rock platforms. They also turn up regularly as a boat capture and as a tackle-testing bycatch for anglers chasing mulloway and other big fish off the beach. A hooked bronzie means long, dogged runs and a serious test of gear and angler. As a large shark, every capture demands respect and careful, safe handling — they are dangerous at the leader and on the sand.
Identification
Bronzie, copper shark, narrowtooth shark, cocktail shark (small fish)
A classic requiem shark: bronze to olive-grey above, sharply white below, with a moderately pointed snout, a large first dorsal set behind the pectorals, and no ridge of skin between the dorsal fins — which separates bronzies from dusky whalers, the other big coastal whaler in WA, which has one. The upper teeth are narrow and hook-shaped rather than broad triangles. The identification that matters most is the one people get wrong in a hurry: white sharks are totally protected, and they carry a blunt conical snout, black eyes, broad serrated triangular teeth and a hard keel on the tail wrist.
How to Catch
Large fish baits — whole tailor, salmon, mullet or eel, fish heads, salmon and tuna frames, stingray flaps
N/A — bronze whalers are a bait-fished species
Heavy land-based-game or boat gear. A long heavy mono or single-strand wire trace (the latter to prevent bite-off) running to a strong 10/0–12/0 hook, beneath a rubber-banded balloon or float to drift the bait out, or a heavy running-sinker rig to anchor it on the bottom. 24kg–37kg outfits, heavy leaders and a quality reel with plenty of line are the norm. Use circle hooks for cleaner jaw hook-ups and easier release.
From the beach or rocks, drift or cast a large bait out past the gutters, often floated under a balloon on an onshore breeze, and wait — bronzie fishing is a patient, big-bait game often worked at night. Set the drag heavy and be ready for a long run. From a boat, a berley trail and floated baits bring them up. When the fish is at the leader, control it carefully; never bring a green shark onto the sand or into the boat. Most anglers tag and release.
Caught year-round, with the warmer months (and the autumn salmon run, which draws sharks into the surf) the most productive in the south. Night sessions on the beach are classic. Onshore winds, swell and a berley or bait trail concentrate fish; tide changes around dusk and after dark are prime.
Up to 3m and 200kg+, commonly 1.5–2.5m
Year-round (warmer months best in the south)
Size & Growth
Beach and headland bronzies commonly run 1.5–2.5 m; a three-metre fish is a big one and the heaviest animals push past 200 kg. They are slow-growing, late-maturing and produce small litters of live young, which is a poor combination under fishing pressure and part of why a maximum size limit applies in the West and South Coast bioregions — the big breeding animals have to go back. Length is usually eyeballed on the sand rather than measured, so if a fish looks anywhere near the limit, treat it as over it and release it in the wash instead of dragging it up for a photo.
Diet & Habitat
Bronze whalers follow food: salmon, mullet, tailor, herring and other schooling fish, plus squid, small sharks and rays. They work the surf zone and the gutters right up against the beach, around headlands and rock platforms, through bays and out to the shelf, moving inshore whenever bait moves inshore — which is why the autumn salmon run down the lower west and South West turns the surf into shark water. They occur right around the WA coast but are most associated with temperate water, from the metropolitan beaches south through Mandurah, Bunbury and Augusta and around to Albany and Esperance.
WA Size & Bag Limits
| Maximum size | 700 mm interdorsal fin length (West and South Coast bioregions) — large bronzies must be released |
|---|---|
| Bag limit | 3 (the shared sharks and rays limit) |
| Counts toward | Counts within the statewide sharks and rays mixed daily bag of 3, separate from the large pelagic finfish bag. Sharks must be carried whole or trunked for identification. |
Bronze whalers are whaler sharks and fall within the statewide sharks and rays mixed daily bag of 3 (separate from the large pelagic finfish bag). In the West and South Coast bioregions a maximum size limit applies to whaler sharks (700mm interdorsal fin length), so large bronzies must be released. Sharks must be carried whole or trunked for identification.
Eating Quality
Edible but not prized, and in WA overwhelmingly a sport-and-release fish. Small whalers are what gets sold as 'flake', and handled properly the flesh is white, dense and boneless — fine battered or in a curry. Handled badly it reeks of ammonia, because sharks carry urea in the flesh that breaks down after death: bleed the fish immediately, get the flesh off the carcass within an hour or two, and soak the fillets in milk, brine or acidulated water before cooking. The health advice matters more than the recipe. Shark is high in mercury, and Australian food-safety advice is to limit shark or flake to about one serve a week with no other fish that week, and less again for pregnant women and young children. The maximum size limit means the big ones go back regardless.
Perth Tips
South West and lower west surf beaches and headlands are the land-based-game grounds, with the autumn salmon run a reliable drawcard. This is a dangerous animal — never put hands near the mouth, never drag a green shark up the sand, and have proper trace pliers, a de-hooker and gloves. Tag and release is the norm; if you must handle one, keep it in the wash, work fast, and put it back. Fish with a partner for LBG sessions.
