Elasmobranch Biodiversity, Conservation and Management Proceedings of the International Seminar and Workshop, Sabah, Malaysia, July 1997
The IUCN Species Survival Commission Elasmobranch Biodiversity, Conservation and Management Proceedings of the International Seminar and Workshop, Sabah, Malaysia, July 1997 Edited by Sarah L. Fowler, Tim M. Reed and Frances A. Dipper Occasional Paper of the IUCN Species Survival Commission No. 25 IUCN The World Conservation Union Donors to the SSC Conservation Communications Programme and Elasmobranch Biodiversity, Conservation and Management: Proceedings of the International Seminar and Workshop, Sabah, Malaysia, July 1997 The IUCN/Species Survival Commission is committed to communicate important species conservation information to natural resource managers, decision-makers and others whose actions affect the conservation of biodiversity. 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. -

Tewes, Kulka, D.W. Graham, R.T. Bizzarro, J.J. Fordham, Ebert, S.V. Carlson, D.A. J.K. Kyne, P.M. Edited by and Caribbean Chondrichthyans Executive Summary This report from the IUCN Shark Specialist Group includes the first compilation of conservation status assessments for the 282 chondrichthyan species (sharks, rays, and chimaeras) recorded from North American, Central American, and Caribbean waters. The status and needs of those species assessed against the IUCN Red List of Threatened Species criteria as threatened (Critically Endangered, Endangered, and Vulnerable) are highlighted. An overview of regional issues and a discussion of current and future management measures are also presented. A primary aim of the report is to inform the development of chondrichthyan research, conservation, and management priorities for the North American, Central American, and Caribbean region. Results show that 13.5% of chondrichthyans occurring in the region qualify for one of the three threatened categories. These species face an extremely high risk of extinction in the wild (Critically Endangered; 1.4%), a very high risk of extinction in the wild (Endangered; 1.8%), or a high risk of extinction in the wild (Vulnerable; 10.3%). -

Status of Shark Fisheries in the Maldives
IOTC–2011–WPEB07–56 Status of Shark Fisheries in the Maldives Hussain Sinan, Fisheries Management Agency, Ministry of Fisheries and Agriculture, H. Whitewaves, Malé, Republic of Maldives M. Shiham Adam, Marine Research Centre, H. Whitewaves, Malé, Republic of Maldives R. Charles Anderson, P.O. Box 2074, Malé, Republic of Maldives Summary Maldivian fishermen have exploited sharks on a small scale for centuries if not millennia. They traditionally targeted large sharks (particularly large tiger sharks), which have enormous livers, from which oil was obtained to treat their wooden fishing boats. Shark meat and fins were of limited interest. That changed between the 1960s and the early 1980s, with the introduction of new fishing techniques (notably longlining for reef and oceanic sharks, netting for reef sharks, and deep vertical longlining for gulper sharks) and the development of new overseas markets for shark products (especially shark fins, but also dried shark meat and squalene-rich liver oil). All of these fisheries prospered, but only for a short time. The deepwater gulper shark fishery went into decline within 5 years, and was effectively finished by the early 1990s. Reef sharks were also soon overexploited, and this fishery was in decline by the mid-1990s. The oceanic shark fishery (which exploited the initially much more abundant oceanic sharks) lasted longer, but even here catch rates were declining by the 2000s, causing many fishermen to desert the fishery. Reef sharks are of great economic importance to diving tourists, and this led to conflict of interest between tourism operators and shark fishermen. Various shark fishery management measurements failed to halt the decline of reef shark abundance. -

5th Meeting of the Scientific Committee Shanghai, China, 23 - 28 September 2017 SC5-DW09_rev1 Ecosystem approach considerations: Deepwater chondrichthyans (sharks, rays and chimaeras) in the Western SPRFMO Area Clinton Duffy1, Shane Geange1 & Tiffany Bock2 1 Department of Conservation 2 Ministry for Primary Industries 1 23 Aug 2017 SC5-DW09_rev1 1. Purpose of paper This paper provides a characterisation of the catch of chondrichthyans in New Zealand bottom fisheries in the SPRFMO Area and information on potential risks to deepwater chondrichthyan species from SPRFMO bottom fishing. Chondrichthyans, particularly those which predominantly occur or complete most of their lifecycle below 200 m depth, are known to have life history characteristics which make them especially vulnerable to fishing pressure. 2. Background About half of chondrichthyans are considered deepwater species, of which around half are sharks (predominantly squaloid dogfishes, Order Squaliformes, and catsharks, Order Carcharhiniformes, Families Pentanchidae and Scyliorhinidae)), with the remainder being skates (predominantly Arhynchobatidae, Rajidae, and Anacanthobatidae), and holocephalans (Kyne & Simpfendorfer 2007). There are currently 177 species reported from the SPRFMO Area that are known to regularly occur below 200 m depth (Appendix 1). Chondrichthyans generally exhibit relatively slow growth rates, late age at maturity, low fecundity and low natural mortality. Knowledge of the growth and reproductive parameters of most deepwater species is generally poor or completely lacking. For the limited number of deepwater species for which sufficient life history data is available, their estimated intrinsic rebound potential values (i.e., ability of a species to recover from fishing pressure) fall at the lower end of the chondrichthyan productivity scale, and include the lowest levels observed (Kyne & Simpfendorfer 2007). -

CASE Chairperson Before the House Committee on ENERGY & ENVIRONMENTAL PROTECTION Monday, June 22, 2020 9:30 AM State Capitol, Conference Room 325 In consideration of SENATE BILL 2717, SENATE DRAFT 1 RELATING TO SHARK PROTECTION Senate Bill 2717, Senate Draft 1 proposes to establish an offense of knowingly capturing, possessing, abusing, entangling, or killing a shark in state marine waters, along with penalties and fines; and provides certain exemptions. The Department of Land and Natural Resources (Department) supports this measure, subject to the following comments and proposed amendment. The Department recognizes the important role sharks play in maintaining healthy marine ecosystems, and the detrimental impact from significantly depleting their populations in our waters. The Department also recognizes the importance of these species for native Hawaiian cultural beliefs and practices, as well as their value for ocean recreation and tourism. The Department supports regulating the take of sharks and rays, and will implement this measure by adopting regulations through the administrative rulemaking process to evaluate and apply scientific management principles, give due consideration to public interests, and carefully craft language to avoid conflict with existing state and federal laws.
