In Argentina, the franciscana dolphin is one of most vulnerable cetaceans regularly entangled in coastal artisanal fishery nets. The aim this paper to estimate species' incidental mortality on Southern coast Buenos Aires province through interviews with captains fishing vessels, period 2006-2009. Franciscana bycatch was reported for gillnets and shrimper gear all year round but it occurred more frequently between October February, at 5 km offshore 10-20 m depth. estimated mean annual 107...
The Franciscana dolphin (Pontoporia blainvillei) is facing significant threats in the Southwestern Atlantic Ocean, largely due to entanglement artisanal fishing nets, which makes it most threatened species region Its conservation calls for a standardised methodology that enables detection and monitoring of populations on longer temporal scale. This study represents first acoustic wild dolphins Argentina, focusing understanding their diel patterns activity relationship with environmental...
The present study provides information about the diet composition of franciscana dolphin, Pontoporia blainvillei, from southern Buenos Aires coast, Argentina.From 2003 to 2011 we collected 66 dolphins that were incidentally entangled in artisanal fishing nets.We analyzed stomach contents and estimated prey size order evaluate overlapping with fisheries.We identified 11 species contents; only two them important diet, striped weakfish, Cynoscion guatucupa, squid, Loligo sanpaulensis.Almost all...

Line transect aerial surveys are widely used for estimating abundance of biological populations, including threatened species. However, estimates obtained with data collected from aircraft often underestimated because visibility bias and in group sizes a fast-moving platform. An assessment multiple sources were carried out Brazilian coastal waters by experiments on survey platforms (i.e., boat, airplane helicopter). These studies focused evaluating (perception availability bias) potential...
The franciscana dolphin ( Pontoporia blainvillei ) is a small coastal endemic to the south-western Atlantic Ocean. Incidental captures in fishing gillnets possibly greatest conservation concern for this species, and occurs within most of its geographical distribution. aim paper determine biological parameters by-caught from artisanal fisheries southern Buenos Aires province, Argentina. Between 2003 2009, carcasses 54 incidentally captured franciscanas were collected. age, sexual physical...
Knowledge of growth patterns an animal species is fundamental to understand their life history. This information also used help define population boundaries threatened cetaceans, such as the Franciscana dolphin, Pontoporia blainvillei . A total 108 dolphins incidentally captured in artisanal fishing nets estuarine and marine coastal waters northern part Management Area IV (North FMA IV), Argentina, were studied. The objective present paper was study age parameters Franciscanas from North...
Marine plastic pollution is projected to increase globally in the next few decades. This holds true for South America where number of species that interacts with plastics increasing. In this study, we explore first time potential certain charismatic marine turtles, mammals and seabirds as indicators Río de la Plata (RdP), one largest most important estuarine areas Southwest Atlantic. Through a revision published studies integrated unpublished data, summarize on interaction region evaluate...

In this paper, we analyze the occurrence, abundance, and type of plastic debris (PD) present on digestive tracts 65 white croakers (Micropogonias furnieri) catches from Rio de la Plata Estuary System (RLPES). Eighty percent individuals analyzed had ingested PD, which 156 were thread-like plastics (FO = 83.9 %) 30 fragments 16.1%). The average number pieces per tract was 2.83 ± 3.14. Microplastic represented 85% majority these <2 mm, preeminent color blue. RLPES is area Southwest Atlantic...
