Sharks, rays, and chimaeras (hereafter ‘sharks’) face a high risk of extinction. Populations many species sharks rays have declined by over 70–90% in last few decades. Immediate action is required to halt population declines allow for recovery. Area-based measures are key biodiversity conservation but commonly do not focus on sharks, existing ones often fail provide them adequate protection. Target 3 the Kunming-Montreal Global Biodiversity Framework commits nations conserving 30% coastal...

The first updated and comprehensive checklist of Chondrichthyes from the southeast Pacific off Peru, based on revision scientific literature, is presented. group in Peruvian coast composed 115 species that include 66 sharks, 43 batoids, six chimaeras. We present nine new records one recent discovery obtained secondary sources. For some species, we also compiled extensions geographic distributions.

The smooth hammerhead (Sphyrna zygaena) is the third most captured shark species in Peru, a nation with one of largest fisheries Pacific Ocean. We sought to better understand trophic ecology this northern Peru by analyzing stomach contents. From 2013 through 2015, we collected 485 samples gut contents from sharks measuring 53-294 cm total length. Our results show that top predator diet dominated jumbo flying squid (Dosidicus gigas) and Patagonian (Doryteuthis (Amerigo) gahi). Smooth...
Abstract The identification of important areas (i.e., nursery grounds) is essential for the conservation most shark species. To assess whether Salas y Gómez Island serves as a area Galápagos Carcharhinus galapagensis , we conducted thorough literature review. Multiple lines evidence show that young‐of‐the‐year (YOY); inhabiting remote (1) present higher density around than surrounding deeper oceanic waters and in south‐eastern Pacific, (2) potentially display high fidelity to this area, (3)...
From December 2012 to June 2014, 796 Pacific guitarfish were caught in 183 fishing sets northern Peru. Catch occurred 86.3% of sets. Most individuals mature with a bias toward males. The mean total length for females and males was 83.4 cm, 91.1 respectively. capture per unit effort (CPUE) 12.6 ± 3.4 (km.12 h)
The stomach contents of thresher sharks ( Alopias spp.; 162–385 cm total length) were collected from five landing points in northern Peru during 2015. A 128 sampled, with 38 individuals identified as pelagicus and 90 aggregated to the genus level sp. prevent any misidentification. diet comprised 13 10 prey taxa for A. , respectively. Humboldt squid Dosidicus gigas dominated both groups, only minor differences relation size classes location. shows a high degree specialization average trophic...
Abstract.- This study provides baseline information on the feeding habits of five batoid species from genera Mobula and Myliobatis sampled small-scale driftnet fishery in northern Peru. The diets mobular, munkiana thurstoni consisted mainly euphausiids. Dietary niche breadth indicated a pelagic behaviour specialist trophic level secondary predator for both M. mobular munkiana. In contrast, chilensis peruvianus consumed mostly gastropods crustaceans. benthic chilensis.
Killer whales (Orcinus orca) are widely distributed in all ocean basins, however, their occurrence, distribution, and ecology the southeast Pacific, including Peru, is poorly defined. This study aims to describe occurrence of killer Peruvian waters, with additional description predatory behaviors. Between 2003 2018 there were 29 reports waters which at least 110 individuals observed, pod sizes ranging between 1 15 individuals. Most sightings occurred within continental shelf or close...
Abstract The Peruvian sea represents one of the most productive ocean ecosystems and possesses largest elasmobranch fisheries in Pacific Ocean. Ecosystem‐based management these will require information on trophic ecology elasmobranchs. This study aimed to understand diet, interactions role nine commercial species northern Peru through analysis stomach contents. A total 865 non‐empty stomachs were analysed. Off Peru, elasmobranchs function as upper‐trophic‐level consuming 78 prey items,...
Manta rays (Mobulidae), Mobula birostris and alfredi, are widely distributed in tropical temperate waters. Still, little is known about their movements ecological interactions (e.g. behavior diet). In Peru, M. has only been reported along the northern shore within Tropical East Pacific Marine Province. No official reports exist from central or south Peru Warm Temperate Southeastern On December 22nd 2015, a rare sighting of ~4 m disc width mobulid ray was recorded as video footage near...
El tiburón martillo (Sphyrna zygaena (Linnaeus, 1758)) es una de las especies elasmobranquios más utilizada para consumo humano en el Perú. Sin embargo, se desconoce los niveles mercurio que contiene su carne. Este trabajo tuvo como objetivo evaluar hallados músculo del y posible implicancia la salud humana. Además, determinar si existe correlación entre tamaño mercurio. Analizamos 27 muestras neonatos juveniles capturados norte La concentración varió 0.13 – 0.85 mg kg-1 peso húmedo. Se...
Batoids are among the least studied group of vertebrates and one most vulnerable to fishing. The rasptail skate, Rostroraja velezi, is a bycatch species in northern Peru for which there no studies on its diet. This research aims document diet R. velezi Peruvian coast determine if sex-based differences A total 74 stomachs were collected, 59 had stomach contents. cumulative prey curve showed reliability number samples collected. According prey-specific index relative importance, was dominated...
