ABSTRACT

This document assembles the reports on the marine shrimp and groundfish fisheries of northern Brazil, French Guiana, Guyana, Suriname, Trinidad and Tobago and eastern Venezuela prepared for and during the third Workshop on the Assessment of Shrimp and Groundfish Fisheries on the Brazil-Guianas Shelf, held in Belém, Brazil, from 24 May to 10 June 1999.

Section 2 includes papers dealing with overviews of important shrimp and groundfish resources and their fisheries. Section 3 deals with fisheries management practices in the area in the context of the Code of Conduct for Responsible Fisheries. Sections 4 and 5 contain papers on stock assessment methodology applicable in the region. Sections 6 to 18 deal with national or sub-regional assessments of selected shrimp and groundfish fisheries. Section 17 also deals with the bio-economics of shrimp fisheries in general and in particular with seasonality, risk and uncertainty. Section 19 is a report of a task group on snapper fisheries of the Brazil-Guianas Shelf, it includes a discussion on future management measures.

Section 20 contains a report on a meeting where the results of assessments were presented to the fisheries managers and recommendations were drafted for follow-up activities.

The names and addresses of the various authors can be obtained from the section headings and the list of participants in Section 22. There is an extensive list of references in Section 21.
