Feeding Behavior of Subadult Sixgill Sharks (Hexanchus Griseus) at a Bait Station
RESEARCH ARTICLE Feeding Behavior of Subadult Sixgill Sharks (Hexanchus griseus) at a Bait Station Bryan McNeil1*, Dayv Lowry2, Shawn Larson1, Denise Griffing1 1 Seattle Aquarium, Seattle, WA, United States of America, 2 Washington Department of Fish and Wildlife, Olympia, WA, United States of America * [email protected] a11111 Abstract This is the first in-situ study of feeding behaviors exhibited by bluntnose sixgill sharks. Bait was placed beneath the Seattle Aquarium pier situated on the waterfront in Elliott Bay, Puget Sound, Washington at 20m of water depth. Cameras and lights were placed around the bait box to record sixgill shark presence and behavior while feeding.

Chapter 11 the Biology and Ecology of the Oceanic Whitetip Shark, Carcharhinus Longimanus
Chapter 11 The Biology and Ecology of the Oceanic Whitetip Shark, Carcharhinus longimanus Ramón Bonfi l, Shelley Clarke and Hideki Nakano Abstract The oceanic whitetip shark (Carcharhinus longimanus) is a common circumtropical preda- tor and is taken as bycatch in many oceanic fi sheries. This summary of its life history, dis- tribution and abundance, and fi shery-related information is supplemented with unpublished data taken during Japanese tuna research operations in the Pacifi c Ocean. Oceanic whitetips are moderately slow-growing sharks that do not appear to have differential growth rates by sex, and individuals in the Atlantic and Pacifi c Oceans seem to grow at similar rates. They reach sexual maturity at approximately 170–200 cm total length (TL), or 4–7 years of age, and have a 9- to 12-month embryonic development period. Pupping and nursery areas are thought to exist in the central Pacifi c, between 0ºN and 15ºN. According to two demographic metrics, the resilience of C. longimanus to fi shery exploitation is similar to that of blue and shortfi n mako sharks. Nevertheless, reported oceanic whitetip shark catches in several major longline fi sheries represent only a small fraction of total shark catches, and studies in the Northwest Atlantic and Gulf of Mexico suggest that this species has suffered signifi cant declines in abundance. Stock assessment has been severely hampered by the lack of species-specifi c catch data in most fi sheries, but recent implementation of species-based reporting by the International Commission for the Conservation of Atlantic Tunas (ICCAT) and some of its member countries will provide better data for quantitative assessment. -
On the Capture of a Pregnant Bluntnose Sixgill Shark Hexanchus Griseus (Chondrichthyes: Hexanchidae) from the Gulf of Tunis (Central Mediterranean Sea)
J. Black Sea/Mediterranean Environment Vol. 23, No. 2: 177-182 (2017) SHORT COMMUNICATION On the capture of a pregnant bluntnose sixgill shark Hexanchus griseus (Chondrichthyes: Hexanchidae) from the Gulf of Tunis (Central Mediterranean Sea) Khadija Ounifi-Ben Amor1*, Mohamed Mourad Ben Amor1, Jeanne Zaouali2, Christian Capapé3 1Institut National des Sciences et Technologies de la Mer, port de pêche, 2025 La Goulette, TUNISIA 2Département des Ressources Animales, Halieutiques et des Technologies Agroalimentaires, Institut National Agronomique de Tunisie, 43 avenue Charles Nicolle, cité Mahrajène, 1082 Tunis, TUNISIA 3Laboratoire d'Ichtyologie, case 104, Université Montpellier II, Sciences et Techniques du Languedoc, 34 095 Montpellier cedex 5, FRANCE *Corresponding author: [email protected] Abstract This study presents the capture of a large female Hexanchus griseus in the Gulf of Tunis, northern Tunisia. The total length (TL) of the specimen was 3.5 m and the wet-weight was 220 kg. It was carrying fertilized eggs in both uteri and was at the beginning of the gestation. The distribution of the species off the Tunisian coast and in the Mediterranean Sea is evaluated and discussed. Keywords: Gestation, eggs, total length, distribution, Tunisian waters, Mediterranean Sea Received: 21.02.2017, Accepted: 15.06.2017 Bluntnose sixgill shark Hexanchus griseus (Bonnaterre 1788) is a large shark species known to be widely distributed in boreal, temperate, warm temperate and tropical waters in the Pacific, Indian and both sides of the Atlantic Ocean (Cook and Compagno 2005). H. griseus is caught rather as bycatch in other targeted fisheries for food or recreational activities, thus it appears that some local populations have been severely depleted (Cook and Compagno 2005). -

Assessors & Morgan, D.L. Report Card Remarks Not commercially harvested in Australia Summary The Bignose Shark is a large bodied shark with a likely circumglobal distribution. It inhabits continental shelf edges throughout tropical and temperate marine waters. It is not targeted by fisheries, however it is Source: CSIRO National Fish Collection. Licence: CC By Attribution taken as bycatch in longline, trawl and gillnet fisheries in much of its distribution. It is mistaken for the Sandbar Shark (C. plumbeus) and therefore, little information on population trends have been recorded. Declines in abundance have been reported in the Northwest Atlantic, Maldives and Southeast Asia, causing concern for the status of this species in these regions. In Australia, the Bignose Shark is not commercially targeted and rarely caught. Therefore, globally the Bignose Shark is Data Deficient (IUCN) and within Australia is assessed as Least Concern (IUCN) and Sustainable (SAFS). Distribution The Bignose Shark is circumglobally distributed throughout tropical and temperate waters however, records are discontinuous (Compagno 1984, Anderson and Stevens 1996, Last and Stevens, 2009). It has been recorded throughout the Central Atlantic Ocean (United States, Cuba, Brazil), Mediterranean Sea, the Indian Ocean (South Africa, India, Red Sea, Sri Lanka) and Northwest Pacific Ocean (China, Thailand, Mexico, California, Peru) (Compagno 1984, Anderson and Stevens 1996, Last and Stevens, 2009). Within Australia it is found in from Cape Leeuwin (Western Australia) north and east to northern New South Wales (Last and Stevens 2009). -
