Shark species composition and catch variability in Guatemala’s artisanal Pacific fishery: A call for spatial and temporal management

M.B Chacón-Paz, Julio Sánchez-Jiménez, Elisa Areano, Juan Carlos Pérez‐Jiménez

Artisanal shark fisheries along the Pacific coast of Guatemala operate with minimal regulation, raising concerns about the sustainability of catches and the conservation of vulnerable species. In support of Guatemala’s National Plan of Action for Sharks, Rays, and Chimeras (NPOA-Guatemala), this study …

Improving Fishery Refuge Zones in Mexico through a comparative analysis of spatial fisheries management tools in the Americas

José Manuel Dorantes-Hernández, Hem Nalini Morzaria‐Luna, Juan Carlos Pérez‐Jiménez, Eva Virginia Coronado-Castro et autres

In Mexico, Fishery Refuge Zones (FRZs) are a spatial fisheries management tool grounded in Marine Spatial Planning principles, with a particular focus on small-scale fisheries. This study evaluates the implementation of FRZs through a comparative analysis with spatial fisheries management tools applied …

Integrating Social and Ecological Dimensions in Fisheries Sustainability: A Comparative Analysis of Assessment Frameworks

Leonora Fernanda Mondragón-Sánchez, Juan Carlos Pérez‐Jiménez, Edgar Tórres-Irineo

ABSTRACT Conventional fisheries assessments, traditionally based on production and structural models, have shown limitations in addressing the complexity of fisheries. Holistic approaches that integrate ecological, social, and governance dimensions are increasingly promoted under the ecosystem approach to fisheries (EAF) and the social‐ecological …

Closing the Gaps: Integrating Biological, Ecological and Taxonomic Data to Support the Identification and Conservation of the Atlantic Pygmy Devil Ray ( Mobula hypostoma )

Atlantine Boggio‐Pasqua, Kim Bassos‐Hull, Guy M. W. Stevens, Jorge Manuel Morales‐Saldaña et autres

ABSTRACT The Atlantic pygmy devil ray ( Mobula hypostoma ) is an endangered mobulid species whose conservation is hindered by taxonomic confusion and significant gaps in ecological and life history knowledge. Here, we present an integrative study that clarifies the species' taxonomic …

Habitat use of the Pacific eagle ray Aetobatus laticeps (Myliobatiformes: Aetobatidae) in a marine protected area of touristic importance, Banderas Bay, Mexico

Alejandra Castelo-Corona, Adrián Maldonado-Gasca, Juan Carlos Pérez‐Jiménez, Javier Tovar‐Ávila

Introduction: Aetobatids have low reproductive potential, with coastal and benthopelagic habits, which makes them vulnerable to anthropogenic activities. Despite this, the Pacific eagle ray Aetobatus laticeps is a poorly studied species, which makes it difficult to assess its populations to implement or …

Global manta and devil ray population declines: Closing policy and management gaps to reduce fisheries mortality

Betty J. L. Laglbauer, Nidhi G. D’Costa, Joshua David Stewart, Marta D. Palacios et autres

Significant progress has been made in advancing priority actions to conserve manta and devil rays, yet implementation and enforcement of protective measures often fall short, leaving most mobulid populations at risk of overfishing. Drawing on a literature review, fisheries databases, agency reports, …

First record and range extension into freshwater habitats of the Atlantic stingray Hypanus sabinus (lesueur, 1824) in southeastern Mexico

Raúl Enrique Hernández‐Gómez, I Valenzuela–Córdoba, Juan Carlos Pérez‐Jiménez, Manuel Mendoza‐Carranza

Records of elasmobranchs in freshwater in México are scarce. Although the Atlantic stingray ( Hypanus sabinus ) is well-documented in U.S. freshwater systems, its presence in Mexican waters is less documented and confined to estuarine environments. Then the aim of this work …

Contrasting vital rate contributions across interconnected populations of a highly vagile avian scavenger: A multisite modelling approach

Diego J. Arévalo‐Ayala, Joan Real, Antoni Margalida, Jaume Adrià Badia‐Boher et autres

Identifying the key drivers of population dynamics in long-lived species is critical for understanding their life history and guiding conservation. However, dispersal processes like immigration and emigration are often overlooked in long-term studies of highly vagile, transboundary species such as vultures, despite …
