Nas últimas décadas, novas tecnologias aquícolas têm sido desenvolvidas e aprimoradas, como o sistema de bioflocos, considerado uma alternativa ao modelo convencional aquícola. O presente estudo compara a viabilidade bioeconômica da produção intensiva em viveiros com a da produção superintensiva em estufas do camarão Litopenaeus vannamei em bioflocos. O investimento para implantação do projeto foi de US$ 767.190,18 para produção intensiva e US$ 807.669,16 para superintensiva. As análises apresentaram valor presente líquido de US$ 363.718,21 e US$ 385.477,42, valor anual equivalente de US$ 59.830,66 e US$ 63.410,00, valor futuro líquido de US$ 965.052,69 e US$ 1.022.786,35, período de payback 4,12 e 4,11, payback descontado 5,64 e 5,63, índice de lucratividade 1,47 e 1,48, taxa interna de retorno 20,49 e 20,55% e taxa interna de retorno modificada 14,61 e 14,64%. As análises de investimentos neste estudo mostraram que a produção superintensiva em estufas é a melhor opção. O desenvolvimento de um novo cenário simulando a produção superintensiva de camarões em sistema de bioflocos, considerando o uso da terra como premissa, permitiu observar a possibilidade de ganhos financeiros em escala tanto na redução dos custos de produção quanto no desempenho econômico do empreendimento. No entanto, a contribuição financeira para implantar e operar o projeto aumentou substancialmente.
