The emphasis has been on fishes generally but these studies have also contributed greatly to our knowledge of chondrichthyans in the region, as well as across the broader Indo–West Pacific. An annotated checklist of cartilaginous fishes of the Philippines is compiled based on historical information and new data. A Taiwanese deepwater trawl survey off Luzon in 1995 produced specimens of 15 species including 12 new records for the Philippines and a few species new to science. -

Frequently Asked Questions
atlaFrequentlyntic white Asked mQuestionsarlin 2007 Status Review WHAT ARE ATLANTIC WHITE MARLIN? White marlin are billfish of the Family Istiophoridae, which includes striped, blue, and black marlin; several species of spearfish; and sailfish. White marlin inhabit the tropical and temperate waters of the Atlantic Ocean and adjacent seas. They generally eat other fish (e.g., jacks, mackerels, mahi-mahi), but will feed on squid and other prey items. White marlin grow quickly and can reach an age of at least 18 years, based on tag recapture data (SCRS, 2004). Adult white marlin can grow to over 9 feet (2.8 meters) and can weigh up to 184 lb (82 kg). WHY ARE ATLANTIC WHITE MARLIN IMPORTANT? Atlantic white marlin are apex predators that feed at the top of the food chain. Recreational fishers seek Atlantic blue marlin, white marlin, and sailfish as highly-prized species in the United States, Venezuela, Bahamas, Brazil, and many countries in the Caribbean Sea and west coast of Africa. White marlin, along with other billfish and tunas, are managed internationally by member nations of the International Commission for the Conservation of Atlantic Tunas (ICCAT). In the United States, Atlantic blue marlin, white marlin, and Atlantic sailfish can be landed only by recreational fishermen fishing from either private vessels or charterboats. WHAT IS A STATUS REVIEW? A status review is the process of evaluating the best available scientific and commercial information on the biological status of a species and the threats it is facing to support a decision whether or not to list a species under the ESA or to change its listing. -

The most suitable methods for processing and inter- preting these calcified structures for age estimation have not been clearly defined. Methodological differences between unvalidated ageing studies are of particular concern for highly migratory species because multiple researchers in dif- ferent regions of the world may conduct age estimates on the same species or stock. This review provides a critical overview of the methods used in previous fin spine ageing studies on billfishes and provides recommendations towards the development of a standardized protocol for estimating the age of striped marlin, Kajikia audax and white marlin, Ka- jikia albida. Three on-going fin spine ageing studies from Australia, Hawaii, and Florida are used to illustrate some of the considerations and difficulties encountered when developing an ageing protocol for highly migratory fish species. -

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. -

Species Composition, Commercial Landings, Distribution and Conservation of Stingrays (Class Pisces: Family Dasyatidae) from Pakistan
INT. J. BIOL. BIOTECH., 18 (2): 339-376, 2021. SPECIES COMPOSITION, COMMERCIAL LANDINGS, DISTRIBUTION AND CONSERVATION OF STINGRAYS (CLASS PISCES: FAMILY DASYATIDAE) FROM PAKISTAN Muhammad Moazzam1* and Hamid Badar Osmany2 1WWF-Pakistan, 35D, Block 6, PECHS, Karachi 75400, Pakistan 2Marine Fisheries Department, Government of Pakistan, Fish Harbour, West Wharf, Karachi 74000, Pakistan *Corresponding author: [email protected] ABSTRACT Stingrays belonging to Family Dasyatidae are commercially exploited in Pakistan (Northern Arabian Sea) since long and mainly landed as bycatch of trawling and bottom-set gillnet fishing, In some areas along Sindh and Balochistan coast target stingrays fisheries based on fixed gillnet used to main source of their landings. It is estimated that their commercial landings ranged between 42,000 m. tons in 1979 to 7,737 metric tons in 2019. Analysis of the landing data from Karachi Fish Harbour (the largest fish landing center in Pakistan) revealed that 27 species of stingrays belonging to 14 genera are regularly landed (January 2019-December 2019). Smooth coloured stingrays (Himantura randalli/M. arabica/M.bineeshi) contributed about 66.94 % in total annual landings of stingrays followed by cowtail and broadtail stingrays (Pastinachus sephen and P. ater) which contributed 24.42 %. Spotted/ocellated/reticulated stingrays (Himantura leoparda, H. tutul, H. uarnak and H. undulata) contributed and 5.71 % in total annual landings of stingrays. Scaly whipray (Brevitrygon walga) and aharpnose stingray (Maculabatis gerrardi) contributed about 1.95 % and 0.98 % in total annual stingray landings of stingrays, respectively. Three species leopard whipray (Hiamntura undulata), round whipray (Maculabatis pastinacoides) and Indian sharpnose stingray (Telatrygon crozieri) are reported for the first time from Pakistan coast. -
Assessing Sharks and Rays in Shallow Coastal Habitats Using Baited
Assessing sharks and rays in shallow coastal habitats using baited underwater video and aerial surveys in the Red Sea Thesis by Ashlie J. McIvor In Partial Fulfilment of the Requirements For the Degree of Master of Science King Abdullah University of Science and Technology Thuwal, Kingdom of Saudi Arabia May, 2020 2 EXAMINATION COMMITTEE PAGE The thesis of Ashlie Jane McIvor is approved by the examination committee. Committee Chairperson: Prof. Michael Berumen Committee Members: Prof. Burton Jones, Dr. Darren Coker, Dr. Julia Spaet [external] 3 © May, 2020 Ashlie J. McIvor All Rights Reserved 4 ABSTRACT Years of unregulated fishing activity have resulted in low abundances of elasmobranch species in the Saudi Arabian Red Sea. Coastal populations of sharks and rays in the region remain largely understudied and may be at risk from large-scale coastal development projects. Here we aim to address this pressing need for information by using fish market, unmanned aerial vehicle and baited remote underwater video surveys to quantify the abundance and diversity of sharks and rays in coastal habitats in the Saudi Arabian central Red Sea. Our analysis showed that the majority of observed individuals were batoids, specifically blue-spotted ribbontail stingrays (Taeniura lymma) and reticulate whiprays (Himantura sp.). Aerial surveys observed a catch per unit effort two orders of magnitude greater than underwater video surveys, yet did not detect any shark species. In contrast, baited camera surveys observed both lemon sharks (Negaprion acutidens) and tawny nurse sharks (Nebrius ferrugineus), but in very low quantities (one individual of each species). The combination of survey techniques revealed a higher diversity of elasmobranch presence than using either method alone, however many species of elasmobranch known to exist in the Red Sea were not detected. -
