O desenvolvimento pesqueiro mundial, a variabilidade dos recursos e a gestão

FAO regularly releases studies on the state of fish resources exploitation (The state of world fisheries and aquaculture)and the development of fisheries by geographic areas. The 1983 and 1985 editions provided interesting discussions on fisheries development trends in the world: the majority of sea-facing countries adopted legislation that extends the national jurisdiction on the waters off their coasts (usually indicated within 200 miles) and establishes exclusive economic zones (EEZs). The huge fluctuations in the abundance of some fish stocks are obstacles to fisheries development. This issue, as well as the need to improve research activities and management of fish stocks is also analyzed in this work. The author highlighted the situation of fisheries in the Western Indian Ocean, with particular attention to tuna fisheries and to inland water resources of Mozambique.

La colección de huevos del Museo de La Plata: especies de Eurasia, Oceanía, África y Norteamérica.

La difusión de datos de las colecciones biológicas es importante, sin embargo su divulgación es escasa. En esta publicación se informa sobre los huevos depositados en la Sección Ornitología del Museo de La Plata. Los mismos son producto de compras, donaciones o de ejemplares provenientes de cautiverio. El objetivo del presente trabajo es dar a conocer las especies de aves de Eurasia, África, Oceanía y América del Norte representadas en esta colección oológica. Esta colección cuenta con aproximadamente 3.800 huevos, 99 de los cuales pertenecen a aves de las regiones que ocupa este estudio. Se destaca Europa (n= 82), seguido por África (n= 6), Oceanía (n= 5), América del Norte (n=3) y Asia (n= 2). Los huevos de estas regiones representan a 17 órdenes, 37 familias y 72 especies; siendo el Orden Passeriformes el mejor representado con un total de 15 familias. El continente europeo es el mejor representado con un 77,5 % del total de las familias y un 87,7 % del total de las especies; con mayor número de ejemplares en los órdenes Passeriformes (n= 41) y Anseriformes (n= 8). Las colecciones son una valiosa fuente de referencia para diferentes tipos de estudios debiendo ser depositadas en lugares que permitan su correcta preservación y que estén a disponibilidad de quienes lo requieran.
