Reconstrução da estatística pesqueira continental do Estado de Sergipe

Abstract

Brazil does not have an electronic database for inland catch statistics. This study is the first to be carried out with the objective of overcome this gap, compiling catch statistics for inland fisheries reported for the state of Sergipe during 1950-2014 and establishing the correspondence between common and scientific name. Towards that end, data from official national bulletins were compiled and interpolation and extrapolations were performed based on historical trends. Main species caught in inland waters of the state were: curimatã (Prochilodus argenteus), tilapia (Oreochromis niloticus and Coptodon rendalli), trahira (Hoplias malabaricus), piau (Leporinus spp.), tambaqui (Colossoma macropomum), corvina (Pachyurus francisci and Pachyurus squamipinnis), piranha (Pygocentrus piraya e Pygocentrus nattereri), catfish (Pimelodus maculatus), carp (Cyprinus carpio), tucunaré (Cichla monoculus) and fresh water shrimp (Macrobrachium acanthurus and Macrobrachium carcinus). Catches for all these species showed a decline between 1999 and 2001. The decline for most of these species was associated with the construction of dams in the region and a strong dry period. Some species, such as “pilombeta” and freshwater crab had their catches reported in the inland section of the national bulletins during some years and in the marine section during others and were excluded from this analysis. We hope this study triggers other researchers to proceed with the reconstruction for other states and finally for the entire country.
