| The picoplankton contribution to the total primary production was evaluated at nine stations on the north western coast of Madagascar. Carbon assimilation expressed as mg C m-2 h-1 varied between 38-79% of the total primaryproduction. Biomass, expressed as chlorophyll a showed the same trend and varied between 34 and 66%. Thecontribution] of the surface picoplankton to total 14C uptake increased from the coast towards offshore incorrespondence with a strong salinity gradient. The sites being investigated are located within an area under intensive fisheries exploitation(Fig. I). This area is reputed to be rich in phytoplanktonic biomass. According to Angot(1967) and Sournia (1988a), the maximum values of biomass are observed during the wet season,... |
