This paper analyzes the changes related to coastal management in the period 2009-2019 in public policies, regulations, competencies, responsibilities, institutions, instruments, training, capacity building, financial resources, scientific knowledge, environmental information and education, and citizen participation. Among the most significant advances are the determination of the limits of the continental shelf, the more precise regulation in the reformed Civil and Commercial Code, the formulation of a Federal Coastal Management Strategy and several sectoral strategies, the creation of the first marine protected area, the increase of the postgraduate courses related to coastal management, and the expansion of the environmental contents to all levels of the education sys...

The objective of this study is to evaluate the bioecology of franciscana in the Rio Negro mouth (41º 3.6' S, 63º 50.4' W), Patagonia, Argentina. Franciscana were observed year round on 431 occasions from January 2002 to January 2004 off Rio Negro mouth totalling 117 groups. Land-based and boat-based observations were conducted. Group dispersion, group size, group composition, behaviour and presence of predators were recorded. Group size ranged from one to five (X = 1.692, SD = 0.7391, n = 117). The group dispersion most frequently observed was 0 DL (n = 28), (X = 1.4, SD = 0.7473, n = 51). The presence of calves was recorded in January 2002 and 2004 (n = 2) and juveniles were observed in September 2003 (n = 1). Behavioural data on movement, feeding, resting and milling were quantified and the most frequent behaviour was travelling (n = 40, 34.19%). Four killer whales were observed in the study area for a day, Two days prior to the appearance of the killer whales, franciscana were recorded in the area, however for two days following, they were not observed. This observation may suggest killer whales as a potential predator of this species in the Rio Negro mouth. Biological data collected on this population of Franciscana indicates habitat in the mouth of the Rio Negro is of prime importance. Rio Negro artisanal fishermen have only recently begun using gillnets, however gillnets have proved to be a hazard for other populations of franciscana as incidental catches are known from throughout its distribution Therefore long-term potential impact of gillnets on franciscana in this area may be high and monitoring is strongly recommended. This is the first long-term study of the species in the Rio Negro mouth.
