Relationships among catches, fishing effort and river morphology for eight rivers in Amazonas State (Brazil), during 1976-1978
For eight rivers in the Amazonas State (Brazil), it is shown that the annual number of fìshermen and dummy variables, which identify the rivers, explain 98.8 % of the landings at Manaus market. Partial correlation analysis suggests that only the most productive floodplains are actively sought by professional fishermen. Keywords: river ecology, floodplain fisheries, multiple regressio
