Fishing strategies among prehistoric populations at Saquarema Lagoonal Complex, Rio de Janeiro, Brazil Anais da ABC (AABC)
Guimarães,Márica B.
Two distinct fishing technologies were identified among the shellmound builders of the Saquarema Lagoonal Complex, in the Brazilian state of Rio de Janeiro: bone point technology and worked fish spines. These technologies were related to the acquisition of specific fish resources; Worked fish spines were used in the capture of Micropogonias furnieri (Desmarest), and bone points used for fishing specimens of the Ariidae family. Worked spines technology was predominant between 6,726 cal. years BP and 3,699 cal. years BP, while the bone point technology was dominant after 3,699 cal. years BP. It is believed these different strategies for obtaining fishing resources before 3,699 years cal. BP was related to environmental. Notably the gradual regression of...

Under the Landing Obligation (LO) fishers will need to reduce or land fish that were previously discarded. In this chapter we look at how they might be able to do that by summarising a number of studies conducted in various European regions. We start by describing a series of “challenge” trials where fishers tried to reduce their discards by whatever (legal) means they thought best. In some cases, they were able to reduce unwanted catches, in others they were less successful. We also interviewed fishers not involved in the trials to ask them what they thought they could do. We explore their approaches which generally fell into three categories: more selective gear; tactical and strategic changes; and management changes. Scientific data (surveys, landings,...

Typologie des flottilles industrielles étrangères ciblant les petits pélagiques dans la zone économique exclusive mauritanienne de 1991 à 1999 OceanDocs
Ould Taleb Ould Sidi, M.M..
Deux Analyses Factorielles de Correspondances (AFC), dont l'une est suivie d'une classification hiérarchique, sont réalisées sur les données de capture des petits pélagiques entre 1991 et 1999 dans la Zone Economique Exclusive mauritanienne. Elles permettent de mettre en évidence les déterminants des stratégies de pêche au niveau de cette zone pour les flottilles les plus importantes. Les facteurs comme l'année, les secteurs, la saison et la flottille sont ceux qui expliquent le mieux les variations des captures observées. Les captures augmentent et se diversifient sous l'effet des changements de stratégie et l'arrivée de nouvelles flottilles dans la zone.
