Port Jackson Shark, Heterodontus Portusjacksoni
Published Date: 1 March 2019 Port Jackson Shark, Heterodontus portusjacksoni Report Card Sustainable assessment IUCN Red List IUCN Red List Australian Endemic to Australia Global Least Concern Assessment Assessment Assessors Huveneers, C. & Simpfendorfer, C. Abundant species that is taken as bycatch but has high post-release Report Card Remarks survival Summary The Port Jackson Shark is an abundant shark Source: Mark Norman/ Museum Victoria. Licence: CC by Attribution endemic to southern Australian waters. It is a large bycatch of several fisheries across its range, however most individuals are returned to the water alive. Studies have shown that the species is highly resilient to capture stress from gillnet, trawl, and longline gear, suggesting high post-release survival rates. Although there was a localised decline of the population in Bass Straight between 1973 and 2001, this trend has been reversed. In addition, an ecological risk assessment showed that the Port Jackson Shark is at low risk from several fisheries because of its low catch susceptibility. The effects of fisheries on the Port Jackson Shark in other areas are likely negligible. Habitat modification and other environmental factors do not appear to be a threat to the population. Therefore, the Port Jackson Shark is assessed as Least Concern (IUCN) and Sustainable (SAFS). Distribution The Port Jackson Shark is commonly found on the southern Australian continental shelf from Byron Bay (New South Wales) south through Victoria, South Australia, and to Houtman Abrolhos (Western Australia), including Tasmania. Records from York Sound (northern Western Australia) and Moreton Bay (Queensland) are questionable. There is a single record of one individual from New Zealand (Last and Stevens 2009). -

Little is known on its population status elsewhere. Considering northern Australia represents the majority of the Nervous Sharks distribution it is assessed as Least Concern (IUCN) and in Australia, Sustainable (SAFS). Distribution The Nervous Shark is found on continental and insular shelves in tropical and sub-tropical waters of northern Australia, southern Papua New Guinea and the Solomon Islands (Last and Stevens, 2009). Within Australia, it is found from Shark Bay (Western Australia), through the Northern Territory and Queensland to Moreton Bay (White and Potter 2004, Last and Stevens 2009, Gutteridge 2012). Stock structure and status In Australia there is currently no information on population size, structure, or trend for the Nervous Shark. It is considered to be sustainably harvested by commercial fisheries in Australia. It is abundant in regional coastal waters of Western Australia (Shark Bay) (White and Potter 2004) and Northern Territory (Darwin Harbour) (Lyle 1987). -

The SSC's Action Plans, Occasional Papers, newsletter Species and other publications are supported by a wide variety of generous donors including: The Sultanate of Oman established the Peter Scott IUCN/SSC Action Plan Fund in 1990. The Fund supports Action Plan development and implementation. To date, more than 80 grants have been made from the Fund to SSC Specialist Groups. The SSC is grateful to the Sultanate of Oman for its confidence in and support for species conservation worldwide. The Council of Agriculture (COA), Taiwan has awarded major grants to the SSC's Wildlife Trade Programme and Conservation Communications Programme. This support has enabled SSC to continue its valuable technical advisory service to the Parties to CITES as well as to the larger global conservation community. Among other responsibilities, the COA is in charge of matters concerning the designation and management of nature reserves, conservation of wildlife and their habitats, conservation of natural landscapes, coordination of law enforcement efforts as well as promotion of conservation education, research and international cooperation. -
Is the Collapse of Shark Populations in the Northwest Atlantic Ocean and Gulf of Mexico Real
perspective conservation Is the collapse of shark populations in the Northwest Atlantic Ocean and Gulf of Mexico real? ABSTRACT Increasing fishing pressure on sharks stocks over recent decades has resulted in declines of many populations and led to increasing concerns for their conservation. The extent of these declines, however, has been highly variable—the result of the level of fishing, ocean condi- tions, and the life history of individual species. Two recent articles have described the collapse and possible extirpation of shark populations in the northwest Atlantic Ocean and Gulf of Mexico. Herein, we examine the results of these two papers commenting on the data sets used, comparing them to other available data sets, and critically evaluating the analyses and conclusions. We argue that these conclusions have been overstated because: (1) the analyses were based on a limited number of data sets, (2) the data sets themselves are inadequate to describe the status of all shark populations in the northwest Atlantic Ocean and Gulf of Mexico reported in these studies, (3) available data sets that could produce different conclu- sions were not utilized, (4) some factors were not taken into account that could have biased the results, (5) there were no alternate hypotheses presented evaluating other causes of the perceived decline, and (6) the authors did not consider any current stock assessments, which in several cases report the status of sharks to be considerably healthier than asserted. Introduction George H. Burgess Sharks are generally regarded to exhibit slow growth, late Lawrence R. Beerkircher maturity, and low reproductive output, making them particularly Gregor M. -

Novel Use of Pop-Up Satellite Archival Telemetry in Sawsharks: Insights Into the Movement of the Common Sawshark Pristiophorus Cirratus (Pristiophoridae)

Page 1/20 Abstract Background Understanding movement patterns of a species is vital for optimising conservation and management strategies. This information is often dicult to obtain in the marine realm for species that regularly occur at depth. The common sawshark (Pristiophorus cirratus) is a small, benthic associated elasmobranch species that occurs from shallow to deep-sea environments. No information is known regarding its movement ecology. Despite this, P. cirrata are still regularly landed as nontargeted catch in the south eastern Australian sheries. Three individuals were tagged with pop-up satellite archival tags (PSATs) off the coast of Tasmania, Australia, to test the viability of satellite tagging on these small elasmobranchs and to provide novel insights into their movement. -
