Effects of short-term capture on the physiology of white sharks
Effects of short-term capture on the physiology of white sharks Carcharodon carcharias: amino acids and fatty acids Austin J. Gallagher, Lauren Meyer, Heidi R. Pethybridge, Charlie Huveneers, Paul A. Butcher ABSTRACT: Empirical evaluations of how overexploited marine fishes respond to capture stress (physiologically and behaviourally) have become increasingly important for informed fisheries management. These types
Fisheries and conservation assessment of sharks in Pacific Panama
Fisheries and conservation assessment of sharks in Pacific Panama Hector M. Guzman, Roberto Cipriani, Angel J. Vega, Jorge Manuel Morales‐Saldaña ABSTRACT: 1. In Panama, shark fisheries were initially developed in the 1980s and progressively increased in production in the 1990s mainly due to the high demand for shark fins and meat from the international Asian
A new strategy proposal to monitor ray fins landings in south‐east Brazil
A new strategy proposal to monitor ray fins landings in south‐east Brazil Rebeca Almeida Marques, Tainá Guimarães Julio, Antonio Mateo Sole‐Cava, Marcelo Vianna ABSTRACT: 1. Statistical fisheries data are usually obtained during landings, through rapid fish classification and their categorization under the trade names given to species or groups of species. However, species classification is

Ecological redundancy between coral reef sharks and predatory teleosts
Ecological redundancy between coral reef sharks and predatory teleosts Shanta C. Barley, Timothy D. Clark, Jessica J. Meeuwig ABSTRACT: Reef sharks may be ecologically redundant, such that other mesopredatory fishes compensate for their functions when they decline in number, preventing trophic cascades. Oral jaw gape, hereafter referred to as gape, determines maximum prey size in

Population productivity of shovelnose rays
Population productivity of shovelnose rays: Inferring the potential for recovery Brooke M. D’Alberto, John K. Carlson, Sebastián A. Pardo, Colin A. Simpfendorfer ABSTRACT: There is recent evidence of widespread declines of shovelnose ray populations (Order Rhinopristiformes) in heavily fished regions. These declines, which are likely driven by high demand for their fins in Asian markets,
