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 This summary of its life history, dis- tribution and abundance, and fi shery-related information is supplemented with unpublished data taken during Japanese tuna research operations in the Pacifi c Ocean.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. -

Ribbon Reefs Dive Site Info
Ribbon Reefs - Dive Sites The Cod Hole The world-famous Cod Hole is home to numerous Potato Cod. These huge fish are quite used to divers, offering the chance to get up close and personal, and are quite willing to pose for a photo whilst visiting one of the many cleaning stations. Whilst usually docile and relaxed, the Cod feed allows divers to see the spectacle of these fish feeding in action. The shallows of Cod Hole offer excellent coral life to explore and the chance to search for many hidden treasures. Follow the terraced reef down for the chance to witness pelagic fish on their way past. Though susceptible to current on an incoming tide, this makes for an excellent drift dive. Marine Life • Giant Potato Cod • Flowery Cod • Spine Cheek Anemonefish • Lionfish • Pygmy Sea Horse • Reef Sharks • Red Bass • Nudibranchs • Lacey Scorpionfish • Ghost Pipefish Dynamite Pass Get the tides right and you are in for a thrilling drift dive along the reef wall of Cormorant Reef. Sit back, enjoy the ride and let Dynamite Pass blow your mind as a plethora of marine life passes right in front of your eyes. Marine Life • Reef Sharks • Lagoon Rays • Flounder • Green Turtles • Sweetlips • Mackerel • Soft Corals • Caverns The Snake Pit An isolated reef between Lizard Island and #10 Ribbon Reef. Living up to its name, this site is famous for the Olive Sea Snakes found here. These snakes tend to be curious of divers entering their domain and have been known to be fascinated with their reflection in a camera lens. -

Occurrence of Tumour (Odontoma) in Marine Fish Sphyraena Jello from the Southeast Coast of India
Vol. 108: 53–60, 2014 DISEASES OF AQUATIC ORGANISMS Published February 4 doi: 10.3354/dao02691 Dis Aquat Org Occurrence of tumour (odontoma) in marine fish Sphyraena jello from the southeast coast of India R. Vijayakumar, A. Gopalakrishnan*, K. Raja, K. Sinduja Centre of Advanced Study in Marine Biology, Annamalai University, Parangipettai, Tamil Nadu, India ABSTRACT: We examined the occurrence of odontoma in the marine fish Sphyraena jello sourced from 3 different landing centers (Cuddalore, Parangipettai and Nagapattinam) in Tamil Nadu (southeast India). A total of 19783 fishes were examined for odontoma presence, of which 2393 were affected with odontoma. The overall prevalence was 12.1% among the 3 stations. Fish landed at Parangipettai showed the highest peak prevalence of odontoma (16.8%) during the pre- monsoon, followed by Nagapatinam (9.1%) during summer 2011. The tumour lengths in premax- illa, supermaxilla and dentary bone were 1.1−3.6, 1.4−5.9 and 1.2−4.1 cm, respectively, and tumour widths were 0.3−1.9, 0.7−3.1 and 0.5−1.9 cm. Higher prevalence (0.206%) of tongue tumour along with odontoma was observed at Nagapattinam whereas it was lower (0.162%) at Cuddalore. Odontoma histopathology showed dense fibrous tissue with fine teeth roots. TEM analysis showed virus-like particles associated with odontoma. Radiography of the odontoma showed that the tumour masses were bony in nature and tissues were merged with upper and lower jaw.

Betanodavirus and VER Disease: a 30-Year Research Review
pathogens Review Betanodavirus and VER Disease: A 30-year Research Review Isabel Bandín * and Sandra Souto Departamento de Microbioloxía e Parasitoloxía-Instituto de Acuicultura, Universidade de Santiago de Compostela, 15782 Santiago de Compostela, Spain; [email protected] * Correspondence: [email protected] Received: 20 December 2019; Accepted: 4 February 2020; Published: 9 February 2020 Abstract: The outbreaks of viral encephalopathy and retinopathy (VER), caused by nervous necrosis virus (NNV), represent one of the main infectious threats for marine aquaculture worldwide. Since the first description of the disease at the end of the 1980s, a considerable amount of research has gone into understanding the mechanisms involved in fish infection, developing reliable diagnostic methods, and control measures, and several comprehensive reviews have been published to date. This review focuses on host–virus interaction and epidemiological aspects, comprising viral distribution and transmission as well as the continuously increasing host range (177 susceptible marine species and epizootic outbreaks reported in 62 of them), with special emphasis on genotypes and the effect of global warming on NNV infection, but also including the latest findings in the NNV life cycle and virulence as well as diagnostic methods and VER disease control. Keywords: nervous necrosis virus (NNV); viral encephalopathy and retinopathy (VER); virus–host interaction; epizootiology; diagnostics; control 1. Introduction Nervous necrosis virus (NNV) is the causative agent of viral encephalopathy and retinopathy (VER), otherwise known as viral nervous necrosis (VNN). The disease was first described at the end of the 1980s in Australia and in the Caribbean [1–3], and has since caused a great deal of mortalities and serious economic losses in a variety of reared marine fish species, but also in freshwater species worldwide. -
18 Special Habitats and Special Adaptations 395
THE DIVERSITY OF FISHES Dedications: To our parents, for their encouragement of our nascent interest in things biological; To our wives – Judy, Sara, Janice, and RuthEllen – for their patience and understanding during the production of this volume; And to students and lovers of fishes for their efforts toward preserving biodiversity for future generations. Front cover photo: A Leafy Sea Dragon, Phycodurus eques, South Australia. Well camouflaged in their natural, heavily vegetated habitat, Leafy Sea Dragons are closely related to seahorses (Gasterosteiformes: Syngnathidae). “Leafies” are protected by Australian and international law because of their limited distribution, rarity, and popularity in the aquarium trade. Legal collection is highly regulated, limited to one “pregnant” male per year. See Chapters 15, 21, and 26. Photo by D. Hall, www.seaphotos.com. Back cover photos (from top to bottom): A school of Blackfin Barracuda, Sphyraena qenie (Perciformes, Sphyraenidae). Most of the 21 species of barracuda occur in schools, highlighting the observation that predatory as well as prey fishes form aggregations (Chapters 19, 20, 22). Blackfins grow to about 1 m length, display the silvery coloration typical of water column dwellers, and are frequently encountered by divers around Indo-Pacific reefs. Barracudas are fast-start predators (Chapter 8), and the pan-tropical Great Barracuda, Sphyraena barracuda, frequently causes ciguatera fish poisoning among humans (Chapter 25). Longhorn Cowfish, Lactoria cornuta (Tetraodontiformes: Ostraciidae), Papua New Guinea. Slow moving and seemingly awkwardly shaped, the pattern of flattened, curved, and angular trunk areas made possible by the rigid dermal covering provides remarkable lift and stability (Chapter 8).
