Significance We conducted a systematic, high-resolution analysis of bottom trawl fishing footprints for 24 regions on continental shelves and slopes five continents New Zealand. The proportion seabed trawled varied >200-fold among (from 0.4 to 80.7% area depth 1,000 m). Within 18 regions, more than two-thirds remained untrawled during study periods 2–6 years. Relationships between metrics total trawling activity footprint were strong positive, providing method estimate where data are not...

Abstract The relationship between fish functional diversity and fishing levels at which its baselines shift is important to identify the consequences of in ecosystem functioning. For first time, authors this study implemented a trait‐based approach Argentine Patagonian Sea vulnerability spatiotemporal changes assemblages incidentally captured by trawling fleet targeting red shrimp Pleoticus muelleri (Spence Bate, 1888) 2003 2014. coupled seven trophic traits reconstructed assemblage for area...
In the Province of Chubut (43°S–47°S), from 2001 to 2005 an on-board observers program analyzed 18 903 fishing hauls captured at depths 19–104 m. Sport tournaments near Puerto Rawson, Chubut, were also monitored 2004 2006. The aim was document southward expansion five cartilaginous fish species and ten bony caught in Central Patagonian waters (Argentina): Psammobatis extenta, bergi, Atlantoraja castelnaui, Sympterygia acuta, Torpedo puelcha, Selene setapinnis, Oncopterus darwini, Dules...
RESUMEN. En el golfo San Jorge se desarrollan varias actividades economicas de relevancia, entre ellas dos pesquerias industriales: la pesqueria merluza comun (Merluccius hubbsi Marini, 1933) y langostino patagonico (Pleoticus muelleri Bate, 1888), ambas solapan espacial temporalmente. del opera una flota fresquera altura, compuesta por unas 20 embarcaciones, costera, 30 embarcaciones. esta pesca alrededor 10% lo capturado en stock sur merluza. congeladora tangonera 80 responsable mas 75%...
animales no objetivo o captura incidental (Kelleher 2008).En las pesquerías de arrastre camarón y langostino, la mayoría especies que componen son descartadas al mar (Stobuzki et al. 2001).A nivel mundial, estimaciones sobre el descarte señalaron estas pesquerías, en particular camaroneras tropicales, fueron por sí solas
Abstract Seabird bycatch in fisheries, and the development of effective mitigation to minimize this, have been subject increasing research attention over past three four decades. Trawl fisheries represent a particular challenge, as bird mortalities (especially highly threatened albatrosses large petrels, Procellariforms) occur primarily through difficult-to-detect collisions with warp net monitoring cables. Effectiveness bird-scaring lines (BSLs) measure can be fleet-specific, studies...
Chondrichthyans are usually caught incidentally in fisheries for species of high commercial value and then discarded on board or landed as by-products. On the coast Chubut province adjacent waters (43°00′S–44°56′S) a bottom trawl fishery has developed targeted at Patagonian shrimp ( Pleoticus muelleri ) common hake Merluccius hubbsi ). Since 2005, this been monitored by On-board Observers Program (POBCh). With aim advancing towards an ecosystem approach, POBCh not only collects information...
Resumen.-Varias especies de langostillas son reconocidas como recursos pesqueros potenciales en todo el mundo .La langostilla Munida gregaria es un componente importante las capturas incidentales pesquerías arrastre la Patagonia Argentina.Se evaluó frecuencia ocurrencia (FO), abundancia relativa (AR) y desti no M. en: a) flota congeladora tangonera (63579 lances), b) fresquera altura (5608) c) costera (584).Las mayores FO AR fueron registradas costera.Sin embargo, dada magnitud tangonera,...
Bottom trawl fishing is the most used worldwide gear generating large amounts of discards due to bycatch a variety species. Shrimp fisheries are recognized for their high incidence in global discards. In waters Patagonia Argentina (43°S - 47°S) an industrial shrimp fishery economic value developed whose target species Patagonian Pleoticus muelleri. The information presented this study comprises period 12 years (2003-2014) and it was gathered by On-board Observer Program. Program collects all...
[Introduction]: Bycatch and discards are a socio-environmental concern that threatens the sustainability of marine life fishing grounds. Approaches to this problem have focused on biological and/or ecological aspects. We considered it necessary explore from social dimension for purpose we explored representations. [Objective]: The aim study is representations bycatch in group businessmen workers capture stage Argentine industrial activity. ask how they evaluate discards, what their causes if...
Al menos unas 70 especies de aves marinas se alimentan en la plataforma continental argentina, que es posiblemente el área con mayor biomasa albatros mundo. La distribución las mar generalmente coincide pesquerías comerciales áreas elevada productividad marina, por lo sus interacciones pueden ser frecuentes y diversas. El abordaje del Mar Argentino considerando a como parte un enfoque integrado representa desafío. Algunos aspectos biología estas podrían actuar indicadores ambientales...
El trabajo describe y caracteriza las cámaras empresariales de la industria pesquera argentina en actualidad. Esta reviste especial importancia no solo por divisas que genera, sino también el mercado asociado a ella forma directa e indirecta. Sin embargo, actualidad, es escasa información disponible respecto del sector empresarial esta trascendente actividad económica. Las investigaciones actuales ciencias sociales sobre versan principalmente rol los asalariados, sus asociaciones gremiales...
