Western Rocklobster
Panulirus cygnus
Other Names
West Australian crayfish, western cray.
Family
Palinuridae (spiny lobsters).
Description, Location, Habitat and Harvesting Information
Available wild-caught, these marine crustaceans are closely related to Tropical Rocklobsters. Found from Shark Bay to Albany, WA they are endemic to Australia. They shelter under rocks, on ledges and among coral to depths of 200m, although commonly 35-60m. By far the most valuable commercial species in Australia (worth over half the value of total Australian finfish catch), they are caught mainly in pots and mostly exported live or frozen to Japan, Taiwan or China. They are less colourful than Tropical Rocklobsters, with reddish-purple shells (pale pink if freshly moulted), their antennae are very long and the flagella on the medium-length antennules between the antennae are also long and forked (though not as long as those on the Tropical). Rocklobsters are mostly active after dark and are carnivorous scavengers, feeding on bottom-dwelling invertebrates.
Season
Supplies peak from December to May, with closure from July to November.
Size and Weight
Commonly 8-10cm and 500g-1kg, though they have reached 5.5kg.
Price
High priced.
Relations
Eastern Rocklobster, Southern Rocklobster, Tropical Rocklobster, Champagne Lobster.
To Buy
Sold whole and as tails. Look for brightly coloured, firm, intact, lustrous shells, without any discolouration, particularly at joints, and a pleasant fresh sea smell. If possible buy live, avoid green (raw, dead) Rocklobsters (except for frozen tails) as it's hard to tell how long they’ve been dead.
To Store
Live crustaceans should be consumed as soon as possible after purchase. Place in a container, cover with damp paper or cloth and keep in the warmest part of the refrigerator, which is usually the crisper (optimum 5°C). Wrap dead Rocklobsters in plastic wrap or place in an airtight container. Refrigerate for up to 3 days or freeze for up to 3 months below -18ºC.
To Cook
Average yield is 35% of total weight (almost entirely in the tail) and up to 45% in small specimens. Has a sweet rich flavour, low oiliness and moist, medium-firm flesh, which is translucent when raw and white with orange tinges when cooked. Leg meat is often a little sweeter than tail meat. Shells turn red when cooked. The most humane, and easiest, method of killing any crustacean is to chill it in the freezer for about 45 minutes until it becomes insensible (but not long enough to freeze it). Once chilled, it should be killed promptly by splitting in half or dropping into rapidly boiling water. See

Cooking Methods
Steam, poach, deep-fry, pan-fry, stir-fry, bake, grill, barbecue, raw (sashimi). Rocklobsters from cooler waters (such as Western) are preferred for cooking. The firm flesh holds together well during most cooking methods. Undercook, rather than overcook, them, as they will continue cooking in the residual heat; overcooked Rocklobster will become tough and leathery. The carapace can be used to flavour stocks, soups and sauces.
