- W2114749135 abstract "The water hydrology in stuarine areas is essential for the maintenance of this biological system. Considering the socioeconomic importance of shrimp harvest from Formoso River, located in the south coast of Pernambuco, the purpose of this study was to characterize the water quality, the biology of white shrimp Litopenaeus schmitti and the manual and rudimentary harvesting activities in this estuary, in order to enable in the future adequate harvest methods of this species, which is the basic source of the fishermen from the region. Data for this study were based on the fishing activities in 2006. The results showed that environmental conditions of Formoso River estuary influenced the frequency of Litopenaeus schmitti , where they were found in muddy bottoms and with high organic matter, in shallow water depths. The populational density varied according to station of study, it was higher at mean region of the estuary. The salinity varied between 15 and 40ppm. The rainfall indexes of rainy season affected the frequency of shrimps. The manual and rudimentary harvest is common, where fishing gear of trawling type and floating net are produced by the fishermen of region themselves. Most fishermen use rowing boats and sailing boats. Only 10% perform motor boat fishing. The fishing frequency is about three or four times a week, in daily and night shifts. 80% of the interviewees (fishermen) have a monthly income lower than a minimum salary. The rate of illiteracy among the older people is significant and the housing conditions are precarious. The studies on Formoso River estuary showed that it presents ecological implications as a result of environmental variations and anthropogenic" @default.
