Resumen

This study aims to establish keys for the conversion of weight commercial categories of the southern brown shrimp,  Farfantepenaeus subtilis , into length and weight frequency classes off the Brazilian Amazon Coast. Data on shrimp  length were obtained by sampling the fisheries from Belém, northern Brazil, from May to August, 2008 and from  November, 2011 to June, 2012. Data on shrimp weight were obtained during 20 months between 2010 and 2012. The use  of conversion keys enables obtaining the total length and weight frequency distributions of shrimp for a specific period,  and the distribution for the total annual catch through a simple extrapolation. Length frequency distribution is the basis  for virtual population analysis and for the assessment of fish stocks
