Description 
Summary

An unusual approach to sample the benthic fish and crustacea macrofauna of the slope of the island of Madeira has been attempted in this project. Due to the inclination and ruggedness of the slope, use of conventional sampling gear is very risky and sometimes impractical for which reason baited fish traps and bottom long lines have been used. Monthly sampling has been carried out every month at 10 sites (100 to 1000 metres depth). Biological cycles as well as biomass and abundance of several species have been determined. Communities distribution and structure are under study. CTD profiles are also carried out monthly. Data have been gathered with the cooperation of the Direccao de Servicos de Estudos e Investigacao das Pescas (Fisheries Laboratory) of Madeira and partially financed by the Junta Nacional de Investigacao Cientifica e Tecnologica (National Scientific and Technological Agency) (Project PMCT/C/MAR/985/90).
