Penaeus esculentus
Introduction '''''Penaeus esculentus''''' (the '''brown tiger prawn''', '''common tiger prawn''' or ''tiger prawn'') is a species of prawn which is widely fished for consumption around Australia.
Ecology Juvenile ''P. esculentus'' live in seagrass beds, and reach sexual maturity at a carapace length of around . Adults grow up to  long, and resemble ''Penaeus monodon'', albeit smaller and browner. They live offshore at depths of up to .
Distribution ''P. esculentus'' appears to be endemic to Australian waters, being found in warm waters from central New South Wales (near Sydney) to Shark Bay, Western Australia, chiefly at depths of . There is little population structure in the species, with only slight differentiation between regions east and west of the Pleistocene land bridge between Australia and New Guinea.
Fisheries and aquaculture Around  of brown tiger prawns are caught each year. Fisheries in Torres Strait are worth around A$24 million per year. It is closely related to ''Penaeus monodon'', with which it can hybridise. It has the potential to be used in aquaculture (shrimp farming) since, although it grows less rapidly than ''P. monodon'', it commands higher prices.
Taxonomic history William Aitcheson Haswell arrived in Australia in 1878, and began working in a marine zoology laboratory at Watsons Bay. In 1879, he described ''Penaeus esculentus'' in a paper in the Proceedings of the Linnean Society of New South Wales, basing his description on material in the Macleay Museum which had come from Port Jackson and Port Darwin, and noting that ''P. esculentus'' is "the common edible prawn of Sydney, and Newcastle, ''etc. ''".
