Relationship between rainfall, pink shrimp harvest (Farfantepenaeus paulensis) and adult stock, associated with El Nino and La Nina phenomena in Patos Lagoon, southern Brazil

The pink shrimp (Farfantepenaeus paulensis) is a very important fishery resource in southern/south Brazil. A great part of the total capture at these regions results from the artisanal fishery activity in Patos Lagoon estuary. The study of this species has importance because it is the main source of income for the communities of artisanal fisheries. This paper relates the climatic effects and the size of the species' adult stock with the harvest of pink shrimp in the estuary, in order to determine the influence of these variables on annual landings (t).
