Recreational Harvest of Sharks and Rays in Western Australia Is Only a Minor Component of the Total Harvest
Recreational Harvest of Sharks and Rays in Western Australia is only a Minor Component of the Total Harvest Matias Braccini ( [email protected] ) Department of Primary Industries and Regional Development Eva Lai Department of Primary Industries and Regional Development Karina Ryan Department of Primary Industries and Regional Development Stephen Taylor Department of Primary Industries and Regional Development Research Article Keywords: elasmobranch, conservation, management, sheries, catch reconstruction Posted Date: February 23rd, 2021 DOI: https://doi.org/10.21203/rs.3.rs-225321/v1 License: This work is licensed under a Creative Commons Attribution 4.0 International License. Read Full License Page 1/20 Abstract Sharks and rays are of global conservation concern with an increasing number of species at risk of extinction, mostly attributed to overshing by commercial shing. Their recreational harvest is poorly known but it can be of similar magnitude to the commercial harvest in some regions. We quantied the recreational harvest of sharks and rays in Western Australia, a region with a marine coastline of > 20,000 km. We recorded 33 species/taxonomic groups but the harvest was dominated by dusky and bronze whalers, blacktip reef shark, gummy shark, Port Jackson shark, wobbegongs, and rays and skates. Most species caught were released (85% of all individuals), although gummy and whiskery sharks were typically retained. There was a clear latitudinal gradient of species composition with tropical and subtropical species of the genus Carcharhinus dominating in the north and temperate species of the families Triakidae, Carcharhinidae, Heterodontidae and Rajidae dominating in the south. The recreational harvest was negligible compared with commercial landings. -

STATUS OF AUSTRALIAN FISH STOCKS REPORT Sand Whiting (2018) Sand Whiting (2018) Sillago ciliata Jason McGilvray: Department of Agriculture and Fisheries, Queensland, Karina Hall: Department of Primary Industries, New South Wales STOCK STATUS OVERVIEW Jurisdiction Stock Fisheries Stock status Indicators Queensland Queensland ECIFFF Sustainable Commercial catch and CPUE, length and age, mortality rate New South Wales New South EGF, N/A, Sustainable Catch, effort and CPUE, Wales OHF length and age, mortality rate EGF Estuary General Fishery (NSW), N/A Not Applicable (NSW), OHF Ocean Hauling Fishery (NSW), ECIFFF East Coast Inshore Fin Fish Fishery (QLD) STOCK STRUCTURE Sand Whiting occur along the east coast of Australia and are most abundant in southern Queensland and northern New South Wales. Tagging studies have shown movement of adult fish between estuaries, but information on biological stock boundaries remains incomplete. The unknown nature of biological stock composition means no formal assessment of the entire biological stock has been completed. Separate assessments of Sand Whiting have been conducted in Queensland and New South Wales [Gray et al. 2000, Hoyle et al. 2000, Ochwada- Doyle et al. 2014, O’Neill 2000]. Here, assessment of stock status is presented at the jurisdictional level—Queensland and New South Wales. STOCK STATUS New South In New South Wales, Sand Whiting are mainly taken by the commercial Estuary Wales General Fishery (by the mesh netting and hauling sectors), with smaller catches reported by the Ocean Hauling Fishery [Hall 2015]. Annual commercial catches of Sand Whiting in NSW waters over the last five years have been well below the preceding 20 year average of 162 t [NSW DPI unpublished]. -
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. -

Fishing and fisheries of Moreton
https://moretonbayfoundation.org/ 1 Moreton Bay Quandamooka & Catchment: Past, present, and future Chapter 7 Industry Protected: Fishing and fisheries of Moreton Bay Abstract Moreton Bay is one of the most intensely used coastal systems in Australia and supports some of Queensland’s most productive fisheries, including Indigenous, commercial, recreational and charter sectors. This paper explores the economic and cultural value of these fisheries to the Moreton Bay region and the challenges they face. Fishing is recognised as one of Queensland’s oldest industries. Marine resources were harvested by Indigenous peoples long before European settlement and continue to form an important part of Indigenous culture today. Commercial fisheries operating within Moreton Bay are valued at $24m per annum, and target a variety of species groups including prawns, crabs, squid and finfish such as mullet, bream and whiting. Direct expenditure by the recreational sector in Moreton Bay is estimated to be ~$194m per annum, with fishers harvesting mud crabs, sand whiting, snapper, tailor and bream, among others. Despite the longevity of these sectors, a number of challenges exist. These include managing risks related to climate change, a growing urban population, and the need to mitigate environmental impacts from fishing and other marine activities. Interactions with other management sectors, including marine park planning and native title rights, will also need to evolve if we are to ensure a sustainable future for the fisheries of Moreton Bay. Keywords: charter fishing, indigenous fishing, industry, prawn, recreational fishing, trawl Introduction Moreton Bay is one of the most intensively fished regions in Queensland. Although it comprises just 3% of the Queensland coastline, it produces about 12% of Queensland’s fish catch ([i]) and supports some of the state’s most productive commercial and recreational fisheries ([ii]). -
