On the diel rhythm of motor activity in perch [Translation from: Informatsionnyi Byulleten Biologiya Vnutrennikh Vod No.30, 12-14, 1976]

The river perch (Perca fluviatilis L.) is most active in the daytime hours, and displays seasonal changes of diel rhythm with a break of the rhythm in spring and autumn. In the present work data were obtained on the motor activity of 3 perch measuring l8-20 cm, caught by net in the littoral of a reservoir and spawned under laboratory conditions. The degree of intensity of movement of perch was judged by special experiments. The results are summarised in this short paper.

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.
