Avaliação dos consumos de materiais estratégicos para a conservação dos engenhos de pesca artesanal de Moçambique e Estudos de constituiçāo tipologia e distribuiçāo de alguns engenhos de pesca artesanal de Moçambique

This technical report comprises two different studies in terms of their conclusions, but based on the same field surveys: “Yearly consumption evaluation of the strategic materials for the artisanal fisheries of Mozambique” and “Constitution, typology and distribution studies of the Mozambican artisanal fishing gears”. In the first of the above studies, the amount of the materials found in each gear, the number of such gears and the wear factor “r” are subject to a computed data processing, producing the following outputs: list of materials demanded in each Mozambican fishing relevant province; list of materials demanded in the whole Mozambican territory. In the second study the observed gears constitutions are analysed and differences and similitudes among them are searched. The details of maneuver and productivity are referred as well. Attention is drawn to the fact that observations did not take place on the whole Mozambican territory, even not in the most representative but in some considerably important fishing centers with reasonable safety and connection facilities. About the first study, when it was not possible to reach such considerably important centers the determination of the approximate picture of them has been achieved by verbal information of people knowing them very well and by the sources referred here in after. Concerning the second study inferences have not been made. Although a limited number of samples has been collected, the accuracy of it has been checked by inquiry. Speculations have been developed only on observed cases. The surveys have been made by a team, assigned by the directors of UD-PPE and Equipesca, under author’s coordination.

The Development of Ceylon's fisheries (a symposium)

In July, 1964, it was decided that a Government Fisheries Corporation be set up. At the request of the Directors-designate of this Corporation a series of lectures on the development of Ceylon's fisheries was organised by the Fisheries Research Station, all except two being delivered at a seminar on 15th September, 1964. The speakers were asked to prepare and submit their texts and these are presented in the sequence in which the talks themselves were delivered: 1. Ceylon's fisheries: past and future (A.C.J. Weerekoon) 2. Fisheries by-products (C.St.E. Gunesekara) 3. The role of technology in fisheries development in Ceylon (N.N. De Silva) 4. Seaweeds (M. Durairatnam) 5. Coastal fisheries (T.P. Goonewardente) 6. The trawler fishery (A.S. Mendis) 7. A review of Japan's tuna long-line fishery in the Indian Ocean (K. Sivasubramaniam) 8. Off shore and deep sea fishery for larger scombroids in the Indian Ocean (K. Sivasubramaniam) 9. The development of fresh water fisheries in Ceylon (H.H.A. Indrasena) 10. Brackish-water fish farming in Ceylon (T.G. Pillai) 11. The role of inland waters in relation to the development of Ceylon's fisheries and a note on the pearl oyster fishery (C.H. Fernando) 12. The mechanization of the inshore fisheries and the relationship to fisheries development in Ceylon (E. Kvaran)
