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...

Abstract A specimen of Prionotus punctatus was caught in Bahía Engaño, Chubut Province, Patagonia, Argentina. This extends the known distribution by 900 km and a 5.5° further south from its previous southernmost record. record increases number species genus fish diversity central Patagonia. The presence P. along with other recent reports tropical subtropical lineages Patagonia adds new evidence on ongoing tropicalization Patagonian Sea.

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

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...

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...

Neonates of the tope shark Galeorhinus galeus are captured in sport and recreational coastal fisheries from January to April each year Engaño Bay (42° 58'-43° 41' S), Chubut, Argentina. The presence these neonates is first evidence a pupping area for this south-west Atlantic Ocean. Knowledge areas chondrichthyans important establishing conservation measures appropriate fishing regulations.

The presence of the telescope fish Mendosoma lineatum in Patagonian waters Argentina is reported. second species Latridae recorded south‐west Atlantic Ocean and its Patagonia an addition to both ichthyological fauna Argentinean Sea Ocean.

Abstract Crabs are fundamental in coastal ecosystems due to their role nutrient cycling, habitat structuring, population control and as indicators of environmental health. Investigating the size distribution life stages these species is crucial for understanding ecology designing effective conservation strategies. This study provides data on stage ratios two populations local genus Cyrtograpsus (Decapoda: Brachyura: Varunidae) Playa Cangrejales intertidal. These endemic had not been...

This short report communicates the finding of a Deep-bodied pipefish, Leptonotus blainvilleanus, (Eydoux & Gervais, 1837) [Syngnathiformes, Syngnathidae] in shallow waters San Jorge Gulf, Patagonia Argentina, August 2010. It’s new record for its known distribution range coast South America. Photos and videos are available.

The presence of ladyfish Elops smithi in Patagonian waters is a new addition to the ichthyological fauna Argentinean Sea. This record represents southward extension its known distribution by 8 degrees latitude, ~1500 km. It another example more frequent arrival tropical or subtropical fish species waters.

There are records of seven species hagfishes in the Argentine shelf and continental slope, comprising most diverse region for this group Southwestern Atlantic. Here, authors report occurrence Myxine affinis knappi San Jorge gulf, adding two to ichthyofauna central Patagonia. A specimen M. (447 mm TL; hermaphrodite) was incidentally caught by Patagonian shrimp fishing fleet collected Fishery Observer Program Fisheries Secretariat Chubut Province, Argentina. Subsequently, a second (358 female)...
