| 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... |

| The analytical framework used throughout most of this study is directly inspired from transaction-cost economics, implying that a lot of attention is devoted to monitoring and enforcement costs involved in collective schemes. One of its most important contributions is to show that, with the help of these tools combined with conventional market power considerations, successes and failures of different groups of fishermen according to their technique and site of operation can be well accounted for. The outline is as follows. In Section 1, background information regarding Senegalese small-scale marine fisheries are provided and the methodology of the study based on cross-section data is shortly described. In Section 2, an historical sketch of all recent... |

| The Coastal Project developed at the INIDEP (Mar del Plata,Argentina) offers an analysis on the operative modality of coastal assessment surveys, proposing an information process useful to standardize data collection and processes of future surveys. The efficiency of the evaluation of strata used until the year 1993 was analyzed and a new stratification is proposed. The aim was to define area-strata of importance for the main coastal species, using the traditional stratification of the coastal ecosystem and the mew methodology. The reason for redefining strata is that a decrease was been detected in the number of traditional species and an increment on the biomass of non-commercial species and,associated with it, the development of new explotation areas.... |

| The simple surplus production model introduced is called Local Surplus Production Model (LSPM) because its only assumption is that the mean surplus production remains constant during a short period of years previous to the date of assessment. Its application requires only a short series (3-4 years) of values of an abundance index proportional to the mean real abundance of the resource. The model parameters estimate is performed in a Bayesian context using the SIR (Sampling Importance Resampling Algorithm) algorithm. Simple risk criteria to assess the Maximum Biologically Acceptable Catch and the risks associated to each hypothetical catch level considered are proposed. Application of the model to the whitemouth croaker (Micropogonias furnieri) resource is... |

| Assessment of abundance indexes for whitemouth croaker (Micropogonias furnieri) and brazilian flathead (Percophis brasiliensis) obtained with general linear models: Monte Carlo simulation and analysis of the interactions with the “year” factor. The effect of interactions with the year factor on the annual index of relative abundance obtained with general linear models applied to the cath per unit of effort data of whitemouth croaker and brazilian flathead commercial fleet was evaluated applying the Monte Carlo simulation. Levels on the relative percentage of variance explained by the interactions with the year factor (%RVEAÑO) were determined, above which loss of proportionality between the relative abundance series given by the index and the real series... |

| The spatial and temporal changes of the fish assemblage areas composition at the coastal ecosystem of the western South Atlantic (34 degree -41 degree S) during six springs (1981, 1983, 1994, 1995, 1998 and 1999), were examined. For each assemblage area the most common species and those species that discriminate it from adjacent assemblages areas within years, were identified. Within each area, also resident (common in all years) and facultative (contributing to less than 90% of similarity within any year) species, were studied. Also were identified what parameters control the main structuring of the fish community on the spatial and temporal patterns. In order to determine how the environmental factors influenced the fish community structure, the... |

| 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... |

| 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... |
