| The study aims to discriminate juvenile and adult concentration areas of white croacker Micropogonias furnieri and striped weakfish Cynoscion striatus in two different areas: Argentine-Uruguayan Common Fishing Zone (AUCFZ) and El Rincón (Buenos Aires Prov., Argentina). The length structure and the relative abundance of these two species were analyzed with data from a research cruise carried out by R/V Dr.E.L.Holmberg during November 1994. Data of relative abundance in t/nm2 were considered to define distribution and concentration areas. 49 samples of white croaker and 41 striped weakfish from AUCFZ a, inside the area of Río de la Plata and in front of Montevideo coast, at depths lesser than 8 meters, while the adults were located in the northern coast of... |

| En la actualidad, existen pocos secretos en la pesca y sus sistemas, los métodos de trabajo, los diseños de embarcaciones y artes de pesca son en general muy conocidos pero debemos tener presente que muchas veces un sistema de pesca que produce gran rendimiento en una región y con determinada especie, no siempre dará los mismos resultados en otras regiones. El funcionamiento básico de los varios tipos de artes ha cambiado muy poco a través del tiempo, fuera del posible éxito de la pesca con electricidad no se han introducido nuevos métodos de pesca. En cambio, todos los artes de pesca se están modificando constantemente para poder aumentar su eficiencia mediante la aplicación de nuevos inventos y adelantos tecnológicos. en el diseño y uso de las artes de... |

| Whitemouth croaker Micropogonias furnieri fishery during three intensive fishing seasons in the outer area of the La Plata River (Argentina-Uruguay) is analyzed. Resource exploitation in the South Atlantic area shows a general retraction of the distribution range and an isolation of the La Plata River stock where most of the fishing effort concentrates. The species market evolution brought about, for Argentina and Uruguay, an important shift in its dynamics as of 1992, when the product insertion in Asiatic markets generated an important commercial attraction and a subsequent increase in the fishing effort by the argentine inshore coastal fleet. This caused a change in the fishery development in Argentina and the establishment, in winter, of a fleet... |

| Monte Hermoso (Province of Buenos Aires, Argentina) is a tourist town inhabited by a large number of artisanal fishermen. The aim of this study was to characterize, through a descriptive analysis, the operational activity of the artisanal fleet and quantify the catches landed per species. The ships, of a trucker type, are 6-9 m length equipped with a 40-90 HP outboard motor. The data analyzed derive from purchase slips furnished by a gatherer corresponding to the November 2009-October 2010 period. The target species were stripped weakfish (Cynoscion guatucupa) and patagonian smoothhound (Mustelus schmitti). The former was caught with hand line throughout the year, essentially between September-December. The latter was fished during March-April and... |

| Property rights are important institutions for regulating the use of valuable natural resources from coastal ecosystems. In this case study, we identify and analyze property rights and user patterns related to small-scale coastal fisheries in the Stockholm Archipelago, Sweden. User patterns and user groups have changed significantly over the last century, as commercial fishing has been increasingly replaced by recreational activities. Interviews with local resource users and owners of water properties in two different areas, Möja and Ornö parishes within the Stockholm Archipelago, revealed a very diverse pattern of property and user rights, with a large number of water and fishing rights owners. Recreational fisheries, including both... |

| Since the early works of Balthazar Osório, at the turn of the century, only few papers have been published on the ichthyofauna of São Tomé island. The papers dealing with these fishes were compilations of previous works or the results of a few scientific expeditions (e.g. "Galathea" and "Calypso"). In this paper, we present the results of several surveys carried out from the island over the last decade, together with an annotated revision of the known bibliography for the area. The result is an inventory of the coastal fish of São Tomé island. Our records (124 species belonging to 59 families) are based on fish captured, photographed or observed whilst diving and also on those landed by local artisanal fishermen. In this paper we report a total of 185... |

| Stripped weakfish is one of the ensemble of species known as “variado costero” most frequently landed. Considering that fact, determination of abundance indices is particularly relevant to apply assessment models and make recommendations to allow for a proper fishery management. The aim of this study was to obtain those indices of the species derived from research cruises carried out in the Argentine-Uruguayan Common Fishing Zone AUCFZ area (34°S-39°S) in the 1993-2006 period. In order to improve the traditional estimate accuracy modeling was used. To formulate the general linear models year, stratum, length, bottom salinity, depth factors and population data such as mean size and juveniles percentage were used. The percentages of variance explained in the... |

| Patagonian smoothhound (Mustelus schmitti) is one of the predominant cartilaginous fishes of the Argentine Sea (SW Atlantic Ocean). It is caught, mainly, in the coastal multispecific fishery with nearly other 30 bony and cartilaginous species. The group is known as ‘variado costero’. In this work the smoothhound abundance indices (CPUE) and standardized efforts for the 1992-2008 period in the area between 34~’S-42~’S were estimated. The General Lineal Model (GLM) and data derived from the argentine commercial fleet were used. Other aspects that could affect estimates and trends of the annual indices were also analyzed. Mean CPUE values estimated with the GLM, considered as annual standardized abundance indices, show an increasing trend as of 2000; the... |

| This chapter includes an economic analysis of the small scale fleet of the Mar del Plata harbour, Buenos Aires Province, Argentina. The original study was carried out at the request of the Skippers Fisheries Society to find out the relative efficacy and efficiency of homogeneous groups of associated vessels. Based on the information available, to tune the observed data, assess the relative efficacy and estimate the relative economic efficiency of the fleet, an ad hoc model was designed. Length, gross registered tonnage, engine power and number of crew members were considered and analyzed as structural variables for 1995, 1996 and 1997. No changes in variables for the period were observed so, the efficacy and efficiency analysis was carried out for the year... |
