ABSTRACT:  "Spatial-Temporal Distribution of Micropogonias Furneri in the Uruguayan Coast "      Caterina Dimitriadis, Grupo de Investigación y Formación de Recursos Humanos en Biodiversidad, Centro Universitario Regional del Este (CURE), Universidad de la República, Maldonado
The spatial distribution and dynamics of fishing resources are a consequence of the action of different natural and anthropogenic factors such as environmental conditions, habitat degradation, and intensity of fishing effort. The estuarine area of the Río de la Plata and its oceanfront are characterized by a great variability in their environmental conditions, significantly influencing the distribution of the main fishing resources targeted by the artisanal and industrial fleets. The objective of this study is to analyze the spatial-temporal variation in the catches of Micropogonias furnieri, by the Uruguayan artisanal fishery in relation to fishing gear, fishing effort, and environmental variability (sea surface temperature, turbidity, depth and wind speed). GIS was used to build a database, which included 3,985 geo-referenced fishing events recorded between 2002 and 2010, linked to their corresponding catches and explanatory variables. Database was later modeled using a GLMM approach to investigate the effect of the considered factors on the spatial-temporal catch of the species. Likewise, the spatial structure of the variation of the resulting abundance index was analyzed to obtain predictive catch maps. It is expected that the results obtained will be a relevant input to define management measures at national and regional levels since because M. furnieri is also exploited by the artisanal fleets of Argentina and Brazil.
