This study investigated the level of seabird mortality caused by domestic trawl fleet (freshies) for hake (among other less important targets) operating in waters off central Patagonia (37–48°S), analyzing effect environmental and operational variability on interactions. With a total 135 vessels, is one largest Argentina. Specifically tasked observers were placed onboard trawlers during summer winter seasons years 2006 2007. The type number interactions (i.e. contacts with fishing gear)...
The incidental mortality of albatrosses Diomedeidae and petrels Procellariidae by longline fishing vessels, has been assessed analysed in several areas the globe. We provide first direct estimates rates along Argentine Shelf shelf break. estimated by-catch rate for whole period (1999-2001) was 0.04 birds/1,000 hooks, with a maximum 0.20 hooks observed 1999. Annual captures averaged 1,160 birds; however, large variation indicates that annual may be order thousands, around 10,000 seabirds...
Seven species of the family Sciaenidae have been reported inhabiting bottom waters Río de la Plata estuary. Of these juvenile stripped weakfish (Cynoscion guatucupa), king (Macrodon ancylodon), whitemouth croaker (Micropogonias furnieri) and banded ground drum (Paralonchurus brasiliensis) are by far most abundant. These also important prey several top-predator among large fishes, seabirds mammals. In this study we provide new information regarding otolith morphology body size relationships...
Abstract During the last centuries, populations of marine megafauna—such as seabirds, turtles, and mammals—were intensively exploited. At present, other threats such bycatch pollution affect these species, which play key ecological roles in ecosystems apex consumers and/or nutrient transporters. This study analyses distribution six megafaunal species (Chelonia mydas, Caretta caretta, Dermochelys coriacea, Thalassarche melanophris, Otaria flavescens, Arctocephalus australis) coexisting...
El sistema fluvio-marino del Río de la Plata (SFMRP) es un ambiente complejo, dinámico y altamente productivo dentro cual las aves marinas tienen particular relevancia. Este sistema, gran importancia ecológica, meteorológica oceanográfica para región, propicia el desarrollo actividades humanas que traen aparejados problemas conservación. En este trabajo caracterizamos los ensambles su relación con ocurren en área desde una perspectiva ambiental. Dentro ensamble (ca. 74 especies) SFMRP,...
Bycatch in commercial fisheries remains a significant environmental issue, with global implications for biodiversity and ecosystem integrity. Despite various mitigation measures available, their adoption by Argentina is inconsistent. This study examines the social factors influencing implementation of bycatch within Argentina's offshore bottom trawl fleet. Through qualitative analysis 29 stakeholder interviews—including fishers, executives, government managers, researchers, NGOs—four main...
ABSTRACT The continental shelf and shelf‐break of the Southwest Atlantic are among most productive biodiverse regions globally. Incidental mortality from fishing activities poses a significant threat to seabird populations in this area. overlap between operations distributions leads bycatch, particularly longline fisheries where seabirds get hooked during setting or hauling operations. This study is first Argentina assess incidental considering cryptic mortality. We estimated potential...

Abstract Seabirds, particularly albatrosses, are among the most threatened birds as a result of their continuous exposure to anthropic pressures including interaction with commercial fisheries, climate change and pollution. Several studies that have focused on spatial distribution foraging seabirds identified certain level segregation between age classes. The black‐browed albatross Thalassarche melanophris is abundant species in South‐west Atlantic Ocean main pelagic seabird interacting...
La importancia de la plataforma continental argentina no está solamente vinculada con su extensión sino también elevada productividad, lo que hace sea utilizada como área alimentación por un importante número y biomasa predadores tope marinos se reproducen en costa sectores insulares alejados del continente. Entre estos tope, las aves pelágicas destacan sus extraordinarias habilidades vuelo extensos viajes o migratorios varios miles kilómetros. distribución estas (y otros marinos) a largo es...
We studied the diet of Southern Caracara (Caracara plancus) at Mar Chiquita Biosphere Reserve, Buenos Aires province, Argentina. identified 3033 prey items (two invertebrate and five vertebrate classes) corresponding to 116 types, from 158 remains 558 pellets collected pairs caracaras. Overall food-niche breadth species level was 11.5 (N = 110 species), majority were insects (69.5%), followed by mammals (23.9%) birds (5%). This pattern noted in spring summer; autumn winter, dominated sample...
Sexual differences in maximum diving depths and the composition of diet Antarctic Shag (Phalacrocorax bransfieldensis) were investigated at Harmony Point, Nelson Island, South Shetland Islands, Antarctica, during 1995–1996 1996–1997 breeding seasons. The mean depth estimated by capillary-tube gauge technique was 37.8 m which, when compared with other studies, reflects good food availability shallow waters around Point. Females dived significantly deeper than males also reached dive...
