"They Come, They Fish, and They Go:” EC Fisheries Agreements with Cape Verde and São Tomé e Príncipe

Fisheries agreements with the European Community (EC) are an important component of the fisheries sector in Cape Verde and São Tomé e Príncipe, constituting today a key source of income for the respective fisheries administration. In spite of this, and of the fact that these agreements have been renewed several times over the past decades, challenges remain in domains such as control and communication of fishing activities, follow-up of financial counterparts, and integration of European fleets’ operations with the Cape Verdean and Santomean economies. This paper analyzes the EC fisheries agreements with Cape Verde and São Tomé e Príncipe in terms of those domains, considering both the contents of the agreements and their practical implementation. The fisheries sector in each of these countries is reviewed, as are some of the fundamentals and criticisms of EC fisheries agreements. It is argued that the agreements with Cape Verde and São Tomé e Príncipe will not live up to the stated objectives of sustainability and responsibility in fisheries until improvements are made to the control of EC vessels, the follow-up of funds paid by the EC, and the size and diversity of benefits accruing to the fisheries and related sectors in the two countries

Ictiólogos de la Argentina: Aurelio Juan Santiago Pozzi

This series will include all those people who, by means of their contributions, great and small, played a part in the consolidation of ichthyology in Argentina. The general plan of this work consists of individual factsheets containing a list of works by each author, along with reference bibliography and, whenever possible, personal pictures and additional material. The datasheets will be published primarily in chronological order, although this is subject to change by the availability of materials for successive editions. This work represents another approach for the recovery and revalorization of those who set the foundations of Argentine ichthyology while in diverse historical circumstances. I expect this to be the beginning of a major work that achieves the description of such a significant part of the history of natural sciences in Argentina.

Os recursos de algas marinhas de importáncia económica na República popular de Moçambique com especial referéncia para Euchema (Florideae) em Cabo Delgado

Composition, abundance and environmental characteristics of the sea-weed resources of Mozambique were investigated along the whole Mozambican sea shore between May, 1979 and November, 1980. The limits of distribution of tropical algae were identified and located close to parallel 21 degree 00'S. Important concentrations of sea-weeds were found in the southern region, but only the Euchema resource in the coast of Cabo Delgado looked promising for commercial exploitation. Biological studies of Euchema were undertaken, the results of which permit the recommendation of a strategy for immediate harvesting which could yield 400-500 tons annually. Further proposals for the culture of sea-weeds are also included.

Lista de los peces de la provincia de Santiago del Estero.

Esta serie tiene como finalidad dar a conocer las especies presentes en los diferentes estados provinciales. Tomando como base los trabajos de López et al. (2003), Reis et al. (2003) y Liotta (2006), mencionamos para cada territorio los cambios y novedades posteriores a estas publicaciones. Además, las especies introducidas son señaladas en las tablas I y II. Consideramos que este modesto aporte contribuirá a precisar el conocimiento ictiofaunístico regional, ya que, además de las listas de especies, adjuntamos bibliografía de referencia y el marco biogeográfico e hídrico correspondientes, que podrán ser de utilidad para quienes hagan uso de este trabajo. Por otra parte entendemos que la participación de autores involucrados en la región considerada, le da un verdadero sentido federal a esta contribución, además de reforzar vínculos en los protagonistas de nuestra especialidad. En este nuevo número presentamos la provincia de Santiago del Estero que se encuentra limitada al noroeste por Salta, al norte y noreste por Chaco, al sudeste por Santa Fe, al sur por Córdoba y al oeste por Catamarca y Tucumán. A las 39 especies citadas por Liotta 2006 para la provincia de Santiago del Estero debemos agregar 2 citas, de las cuales 1 es introducida (Tabla II). En el listado no están incluidas 8 especies que requieren confirmación (Tabla III).
