Abstract
O estado de Sergipe não dispõe de uma versão eletrônica oficial do banco de dados de estatística de captura disponível em boletins nacionais impressos. Assim, o objetivo desse trabalho foi atualizar a parte referente ao estado de Sergipe de um banco de dados nacional eletrônico reconstruído, a fim de obter uma série histórica para 1950-2010, analisando a composição da captura com maior resolução taxonômica e estimando componentes ausentes da pesca. As capturas totais reconstruídas foram sempre mais elevadas do que as originais e indicaram um aumento nas capturas de 1950 a 1979. Nas décadas de 1980 and 1990, foi observada uma estabilização nas capturas, e uma queda de 2005 a 2010. As capturas foram extraídas quase exclusivamente pela frota artesanal. A melhor resolução taxonômica permitiu a identificação das seguintes espécies com as de maiores capturas em 2010 : Xiphopenaeus kroyeri, Mugil curema, Ucides cordatus, Goniopsis cruentata e Macrodon ancylodon . As capturas para essas espécies representaram cerca de 50% do total extraído em Sergipe em 2010. Capturas recreativas foram estimadas em 16 t em 2010, e descartes anuais em 818 t nas décadas de 1980 e 1990. Capturas ornamentais e de subsistência não foram estimadas. Nossa análise indicou que perdas taxonômicas foram observadas em duas etapas: quando dados locais são incorporados em um banco nacional e posteriormente, de um banco nacional para um internacional.
Highlights
Sergipe is the smallest state in Brazil, being located in its northeastern region. This state was chosen as the first case study to be analyzed within a larger project aiming at reconstructing Brazilian marine catches (Freire et al, 2014) due to logistic reasons, as there was a project being carried out at the same time dealing with commercial fisheries (Piauí/ Real Rivers Project, A.R.R Araújo, unpublished data) and the possibility of checking correspondence between common and scientific names with local fishers
Based on the official bulletins, annual marine catches of Sergipe for the period 1995-2004 were about 1,600 t, the third smallest marine production in the country, after the states of Amapá and Paraná, a landing database was reconstructed by Freire & Oliveira (2007)
Data provided by the last official bulletin published by IBAMA for 2007 indicated that 11,273 t were produced in Sergipe, 54% from capture and 46% from aquaculture

Later national volumes published by the Ministry of Fisheries and Aquaculture (MPA), from 2008 to 2011, presented only estimated total catches based on models and did not present estimates by species
