             abstract = "Marine fisheries catch in Brazil has been declining for more than 
                         a decade due to over-exploitation of fish stocks, although there 
                         have been slight recoveries in a few years. To be sustainable, 
                         fisheries exploitation requires biomass compensation by solar 
                         powered primary production. Primary production required (PPR) 
                         estimates how much primary production is needed to replace the 
                         biomass of \fisheries catch removed from marine ecosystems. 
                         In the present study, monthly satellite net primary production 
                         fields (PPL) were estimated and used to calculate the annual PPL 
                         rate and to infer total carbon fixed in a pixel-by-pixel basis for 
                         Brazilīs Exclusive Economic Zone (ZEE). PPL was compared to PPR in 
                         the context of the five most commercially exploited species in 
                         Brazil. An index based on PPR/PPL ratio is used to verify if the 
                         five species are fished with PPR demands above (or below) its 
                         average net primary productivity (PPL). Basically, fishing is 
                         constrained by PPL limits. Fishing beyond primary production can 
                         occur, but marine ecosystems are already under overfishing and 
                         climate change pressures compromising their health. Catch data 
                         still require a few adjustments as well as the definition of the 
                         associated PPL areas. However, the present approach can provide 
                         useful information for researchers and support the formulation of 
                         public policies related to fisheries management that considers the 
                         variability and demands of marine ecosystem productivity.",
