Shark-catch composition and seasonality in the data-poor small-scale fisheries of the southern Gulf of Mexico

Shark-catch composition and seasonality in the data-poor small-scale fisheries of the southern Gulf of Mexico

Shark-catch composition and seasonality in the data-poor small-scale fisheries of the southern Gulf of Mexico Juan Carlos Pérez-Jiménez, Armando Wakida-Kusunoki, Chrystian Hernández-Lazo, Manuel Mendoza-Carranza ABSTRACT: Regional ecological information is relevant to the international management of vulnerable species such as sharks. On the basis of monthly fishery data (2007–2010) from two small-scale multispecies fleets, namely, the

Shark and ray community structure in a turbid, nearshore coral reef habitat

Shark and ray community structure in a turbid, nearshore coral reef habitat Arthur Yon, Mark G. Meekan, Samantha Andrzejaczek, Sarah Martinez, Conrad W. Speed ABSTRACT: The coastline of northern Australia may be a refuge for elasmobranchs threatened or extirpated from much of their former ranges across South-East Asia. In this study, we used baited remote

First observations of white sharks attacking a live humpback whale

First observations of white sharks attacking a live humpback whale

First observations of white sharks (Carcharodon carcharias) attacking a live humpback whale (Megaptera novaeangliae) Sasha Dines, Enrico Gennari ABSTRACT: To date, white shark (Carcharodon carcharias) feeding events involving large whales have largely been described only in terms of observed scavenging events. Scavenging occurs in all ecosystems and is usually associated with stochastic feeding events. In

Biological and population parameters of Tiger Shark landed in Tanjung Luar

Biological and population parameters of Tiger Shark Galeocerdo cuvier, landed in Tanjung Luar, West Nusa Tenggara Irwan Jatmiko, Suciadi Catur Nugroho ABSTRACT: Tiger shark is one of the important catch for small scale fisheries in West Nusa Tenggara. It is considered nearly threatened according the IUCN, thus information regarding to its estimated population is needed

First Record of the Longfin Mako Shark for Puerto Rico

First Confirmed Record of the Longfin Mako Shark (Isurus paucus) for Puerto Rico Mignucci-Giannoni AA, Cintrón-Nieves D, Franqui-Rivera G, Espinoza R, Orcera-Iglesias JM, Rivera-Ilarraza PJ, Rivera-Pérez CI, Rodríguez-Ferrer G. ABSTRACT: Isurus paucus (Longfin Mako) is a mesopelagic shark inhabiting tropical and subtropical waters. While records of Longfin Makos have been documented for the Western North

Performance of Two Survey Gears Targeting Elasmobranchs

Performance of Two Survey Gears Targeting Elasmobranchs

Performance of Two Survey Gears Targeting Elasmobranchs in a Shallow, Subtropical Estuary Grace Roskar, Michael P. McCallister, Matthew J. Ajemian ABSTRACT: Fishery‐independent surveys have become increasingly prevalent in recent decades for monitoring the population trends of highly mobile species like elasmobranchs (sharks and rays). Despite the utility of gear evaluations for streamlining costs and increasing

First study on age and growth of the deep-water Goblin Shark

First study on age and growth of the deep-water Goblin Shark, Mitsukurina owstoni (Jordan, 1898) Fabio P. Caltabellotta, Zachary A. Siders, Gregor Cailliet, Fabio S. Motta, Otto B. F. Gadig ABSTRACT: Due to poorly mineralizing structures, ageing deep-water elasmobranchs requires nonconventional techniques. The aim of the present study was to develop a reliable ageing technique

Tourism-driven ocean science for sustainable use: A case study of sharks in Fiji

Tourism-driven ocean science for sustainable use: A case study of sharks in Fiji C A Ward-Paige, J Brunnschweiler, H Sykes ABSTRACT: The oceans are in a state of rapid change – both negatively, due climate destabilization and misuse, and positively, due to strengthening of policies for sustainable use combined with momentum to grow the blue

Morphological deformities in the pelvic fin and clasper in Potamotrygon marquesi

Morphological deformities in the pelvic fin and clasper in specimens of Potamotrygon marquesi (Chondrichthyes: Myliobatiformes: Potamotrygoninae) João Paulo Capretz, Batista da Silva, André Luis da Silva Casas ABSTRACT: We report deformities in the pelvic fin and clasper skeleton in specimens of Potamotrygon marquesi from Acre, Northwestern Brazil. The malformations involve skeletal deformities in the pelvic
