The status of shark and ray fishery resources in the Gulf of California: applied research to improve management and conservation [PDF]
, 2009 Seasonal surveys were conducted during 1998–1999 in Baja California, Baja California Sur, Sonora, and Sinaloa to determine the extent and activities of artisanal elasmobranch fisheries in the Gulf of California. One hundred and forty–seven fishing sites,

Survival of the blacktip shark, Carcharhinus limbatus
, 2020 Proportional survival (S) is a crucial life-history parameter in population dynamics, natural selection, and management of harvested stocks; variations in survival due to age, sex, or geographic region may have large effects on the success of managing fish stocks. The blacktip shark, Carcharhinus limbatus, is the most abundantly harvested shark species

Olfaction Contributes to Pelagic Navigation in a Coastal Shark. [PDF]
, 2016 How animals navigate the constantly moving and visually uniform pelagic realm, often along straight paths between distant sites, is an enduring mystery. The mechanisms enabling pelagic navigation in cartilaginous fishes are particularly understudied.

Speed‐dependent locomotor patterns during steady swimming in a demersal shark
Journal of Fish Biology, Volume 107, Issue 2, Page 394-405, August 2025.Abstract Swimming ability is critical for navigating complex benthic habitats, yet the biomechanical strategies demersal sharks employ to modulate body and fin movements across varying speeds remain largely unexplored. This study examines speed‐dependent kinematic patterns in the small‐spotted catshark (Scyliorhinus canicula), a benthic species with ...

How Fragmented Is eDNA? A Case Study on Shark DNA in Tropical Reef Seawater
Environmental DNA, Volume 7, Issue 4, July–August 2025.This study quantified mitochondrial eDNA fragment lengths in offshore tropical seawater using qPCR assays targeting amplicons from 119 to 15,727 bp in tiger shark (Galeocerdo cuvier). Copy numbers steeply declined with increasing fragment size, with successful amplification up to 1518 bp and a calculated mean undamaged fragment size of 256 bp.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 6, June 2025.ABSTRACT Fishing pressure is the primary threat to coastal elasmobranch populations, and understanding its impact requires long‐term regional data—often lacking in complex, small‐scale fishery settings. This is the case for Curaçao, a southern Dutch Caribbean island with an unmonitored artisanal fishery where, according to anecdotes, elasmobranchs have
