Abstract

Following the observation that the commercial landings of fish on Manaus market are predominantly
produced by the floodplain fisheries, a detailed case study was conducted in a floodplain lake near Manaus.
The general characteristics of the fisheries exhibit a high level of complexity which can be reduced by
considering two types of fisheries: a migration fishery and a lacustrine one. A study of the seasonal
variability shows complex relationships between capture, effort and cpue, and the hydrological regime. The
interannual evolution of these fisheries from 1976 to 1988 is analyzed. The total annual landings are
maximum in the years 1979 and 1980, then decrease until the 1983/84 fishing season and seem to stabilize
at a relatively low level in the last years. The main factor for these variations seems to be natural fluctuations in the fish populations.
