Brown Tiger Prawn (Penaeus Esculentus)
I & I NSW WILD FISHERIES RESEARCH PROGRAM Brown Tiger Prawn (Penaeus esculentus) EXPLOITATION STATUS UNDEFINED NSW is at the southern end of the species’ range. Recruitment is likely to be small and variable. SCIENTIFIC NAME COMMON NAME COMMENT Penaeus esculentus brown tiger prawn Native to NSW waters Also known as leader prawn and giant Penaeus monodon black tiger prawn tiger prawn - farmed in NSW. Penaeus esculentus Image © Bernard Yau Background There are a number of large striped ‘tiger’ prawns waters in mud, sand or silt substrates less than known from Australian waters. Species such as 30 m deep. Off northern Australia, female brown the black tiger prawn (Penaeus monodon) and tiger prawns mature between 2.5 and 3.5 cm grooved tiger prawn (P. semisulcatus) have wide carapace length (CL) and grow to a maximum of tropical distributions throughout the Indo-West about 5.5 cm CL; males grow to a maximum of Pacific and northern Australia. The brown tiger about 4 cm CL. Spawning occurs mainly in water prawn (P. esculentus) is also mainly tropical but temperatures around 28-30°C, and the resulting appears to be endemic to Australia, inhabiting planktonic larvae are dispersed by coastal shallow coastal waters and estuaries from currents back into the estuaries to settle. central NSW (Sydney), around the north of the continent, to Shark Bay in WA. This species is Compared to northern Australian states, the fished commercially throughout its range and NSW tiger prawn catch is extremely small. Since contributes almost 30% of the ~1800 t tiger 2000, reported landings have been between prawn fishery (70% grooved tiger prawn) in the 3 and 6 t per year, with about half taken Northern Prawn Fishery of northern Australia. -

Scientific review, however, does not constitute an endorsement of the Seafood Watch® program or its recommendations on the part of the reviewing scientists. Seafood Watch® is solely responsible for the conclusions reached in this report. 2 About Seafood Watch® Monterey Bay Aquarium’s Seafood Watch® program evaluates the ecological sustainability of wild-caught and farmed seafood commonly found in the United States marketplace. Seafood Watch® defines sustainable seafood as originating from sources, whether wild-caught or farmed, which can maintain or increase production in the long-term without jeopardizing the structure or function of affected ecosystems. Seafood Watch® makes its science-based recommendations available to the public in the form of regional pocket guides that can be downloaded from www.seafoodwatch.org. The program’s goals are to raise awareness of important ocean conservation issues and empower seafood consumers and businesses to make choices for healthy oceans. Each sustainability recommendation on the regional pocket guides is supported by a Seafood Report. Each report synthesizes and analyzes the most current ecological, fisheries and ecosystem science on a species, then evaluates this information against the program’s conservation ethic to arrive at a recommendation of “Best Choices,” “Good Alternatives” or “Avoid.” The detailed evaluation methodology is available upon request. In producing the Seafood Reports, Seafood Watch® seeks out research published in academic, peer-reviewed journals whenever possible. -

Bourne fed.] North Pacific Workshop on stock assessment and management of invertebrates. Can. Spec. Publ. Fish. Aquat. Sci.92. Two species of squat lobsters, Cerv/mumdct johni. Porter, and Pleuroncodes monodon, Milne Edwards, family Galatheidae. are harvested commercially off Chile. A commercial fishery began by exploiting the first spe cies bur. has gradually shifted to harvesting the second. The fishery for Pleuroncodes began in 1966 off San Antonio {L. 33°3S"SJ but has gradually moved southward and now extends to Talcahuano (37°S). There are two possible explanations for this shift in fishing area; (1) increased fishing pressure, and (2) changes in the natural environment. Some support for the second explanation is seen by simultaneous changes observed in other species which may be due to cyclic changes in the environment. Data on the fishery has been collected from 1%b to the present from the area between Coquimbo (30°S) and Talcahuano by the Fisheries Development Institute of Chile (Instituto de Fomento Pesquero, IFOP) by monitoring the fleet at landing ports and from research surveys. -
