eastern crayfish, green lobster, marine lobster, pack-horse
rocklobster
Found only along the coast of New South Wales.
Caught in crayfish pots on the Continental shelf and close inshore.
Very good eating
Did you know? Crayfish can crawl forward at a very slow and awkward pace
but can swim backwards extremely fast to get away from
predators. Their spines point forwards to make them more
streamlined for swimming and harder to grab by predators.

Eastern Rock Lobster:
Rocklobsters
are highly sought after and therefore often highly priced.
Price is usually a reflection of available supply, not
quality. However, export grade rocklobster is always of high
quality and high price.
Rocklobster flesh is firm, with a
sweet medium and rich taste; it retains its shape in most
styles of cooking.
Poached, baked or barbecued, grilled, steamed, or sliced for
sashimi, rock-lobsters make an excellent seafood dish.
However, guard against over-cooking or the meat will become
tough and leathery. Rocklobsters have excellent presentation
potential, so take care not to damage the legs and head.
Traditional sauces to accompany rocklobster are thermidor
and New-burg, but suggestions for other complementary tastes
abound. Try sweet corn, citrus fruits, chillies, tarragon
butter sauces, garlic and white wine, or coconut mild
curries, or combine in quenelles and mousselines. Prepare as
a bisque or serve in a salad with other seafood, or on its
own with fresh green peppercorns and char-grilled pineapple.
If cooking rocklobster in liquid, try a court bouillon
instead of water.
How to humanely kill a Lobster for
cooking:
It is recommended that all crustaceans are immersed in a
salt water/ice slurry for a minimum of 20 minutes before
boiling, broiling, pithing or cutting. This ensures the
animal is immobilised before procedures that may cause pain
are carried out.
The salt water/ice slurry is made by first filling a
suitable container (such as an esky) with normal crushed
ice, then adding salt water (sea water salinity). The ratio
of normal ice to salt water should be 3:1, which will give
the consistency of wet concrete and a temperature of –1°C.
It is important that enough ice is provided to maintain the
temperature of the slurry.

Rock Lobster Commercial Fishing Data for 2010 / 2011
(Australia) In 2009–10, the value of rock lobster production
decreased by 11 per cent ($46 million) to
$368.8 million, following a 21 per cent decrease in the volume of rock lobster
production.
Rock lobsters are caught mainly in Western Australia, South Australia and
Tasmania.
In 2009–10, rock lobster production decreased by 2575 tonnes to 9628 tonnes as a
result
of lower production in Western Australia, South Australia and Tasmania, which
collectively
accounted for 91 per cent of the Australian total volume of rock lobster
production. The
decline was mainly attributable to the significant decreases in production in
Western Australia
and South Australia. In 2009–10, rock lobster production from these two states
combined fell
by 21 per cent (1946 tonnes) from 2008–09 to a total of 7501 tonnes.
Western Australian rock lobster has historically accounted for a larger share
(about 60 per cent
on average) of the total value of Australian rock lobster production, while
southern Australian
rock lobster generally accounted for over 30 per cent. However, since 2003–04,
the relative
share of western rock lobster in value terms has declined compared with southern
rock lobster.
The share of western rock lobster in value terms fell from 65 per cent in
2003–04 to 50 per cent
in 2009–10. In contrast, the share in value terms of southern rock lobster
increased from
30 per cent to 45 per cent over the same period.
Between 2008–09 and 2009–10, catches of both species declined. Although western
rock
lobster catch fell by 22 per cent (1690 tonnes), its value of production fell by
only 4 per cent
because of a 23 per cent increase in the average beach price. Southern rock
lobster catch
fell by a lesser amount, 365 tonnes (10 per cent). Combined with a 4 per cent
decrease in its
average beach price, this resulted in the value of southern rock lobster
production falling
by 14 per cent ($26.2 million) in 2009–10. Production of southern rock lobster
and western
rock lobster contributed $165.5 million and $184.1 million, respectively, to the
total value of
Australian rock lobster production in 2009–10.
