		The species is only found below 400 m above sea level in Tasmanian rivers flowing north into the Bass Strait (with the exception of the Tamar).
		The specific epithet gouldi commemorates the Australian naturalist John Gould.
		gouldi is very long-lived and reproduces slowly, with the result that fishing this species has had a great impact on its abundance, and also explains why the largest individuals now found are smaller than previously.

		Astacopsis gouldi was found in streams of all sizes surveyed.
		gouldi may be described as an intact system of densely canopied streams, of several stream orders including small headwaters, flowing through a relatively undisturbed, forested catchment.

		The Recovery Team for the threatened Tasmanian giant freshwater crayfish, Astacopsis gouldi, has in its Draft Recovery Plan followed a suggestion that the common name 'Lobster' be adopted during the recovery process.
		The argument, as I understand it, is that 'Lobster' has been a common name used for the species, particularly in northwest Tasmania, and that the term is appropriate because it generally refers to 'large crayfish with claws'.
		gouldi reinforces the image of this species as a food in the minds of recreational fishermen.

		The Tasmanian Giant Freshwater Lobster (Astacopsis gouldi) is the largest in the world and reaches over 5kg and 80cm in length.
		Due to overfishing the average size of the animal has been greatly reduced, even though it is now a fully protected species.
		The four genera of freshwater crayfish native to Tasmania are: Astacopsis (3 species), Parastacoides (14- 15 species and currently under revision), Geocharex (1 species) and Engaeus (the freshwater burrowing crayfish) which has fifteen species occurring Tasmania, thirteen of which are endemic.

		Due to the increase of access to lobster fishing areas in the last 20 years, the population of the Astacopsis gouldi has been in decline.
		The main reasons for such a nickname are not just for the fact that the Giant Freshwater Lobster is heading towards extinction, but it is also the largest animal and predator in its freshwater habitat, just like the Thylacine was on Tasmania's land.
		Reproduction in females occurs only every two years, making Astacopsis gouldi very vulnerable to disturbance of the environment or over fishing by humans.
