Abstract

This work aims to provide statistical information about fishing of Sciades parkeri in bragantine region, through sampling performed with daily interviews during the years 2008 to 2010 in nine landing spots. These data were extracted from a project named ESTATÍSTICA PESQUEIRA (Fishery Statistics). A total of 206 landing were registered, counting a volume of 170.694,2 kg and 2009 was the most productive with 50,4% of catches. It were identified seven categories of fishing gear and the active fleet was mainly handmade, however there were bigger boats' records. The highest mean in production was obtained in Bragança, followed by Bacuriteua village. Monthly production's mean increases expressively in local rainy season's beginning (March to May) and extends itself until the months of transition to dry season (June to August). Only the “days at sea” variable presented statistical significance for volume and CPUE landed. The participation of S. parkeri on landing is significant in all year's periods being among the main fishes captured in the region. The active fleet is primarily handmade, with greater autonomy and fishing power if compared to others acting on the coast.
