The methodology used for this was exploratory research implemented in a production unit located in the Northeast Brazil. The scientific article approaches since generic aspects of the technique about the management to use water, energy and the effluent characterization of this productive activity. It discusses quantitative aspects, environmental questions and chances of P+L during the productive process phases. The results points to input economy in the form of feed, soil correctives, medicines, and energy applied to the process, which range from 4% to 27%, emphasizing the small profit should be viewed as a source of considerable environment return. The authors conclude for the adoption property of this technique in this agribusiness segment, point out to the management importance of the input dosage in the quality of the final effluent, besides the adoption of a physical-chemistry remediation mechanism to the residual of Sodium metabissulphite used in the process of shrimp caught / O objetivo do trabalho ? apresentar uma estrat?gia de implementa??o da produ??o mais limpa (P+L) em uma fazenda de cultivo de camar?es. A metodologia utilizada foi pesquisa explorat?ria, realizada pela investiga??o via estudo de caso, implementada em uma unidade produtiva localizada no nordeste do Brasil. O trabalho aborda desde aspectos gen?ricos da t?cnica no que diz respeito ao gerenciamento do uso da ?gua, energia, e da caracteriza??o do efluente desta atividade produtiva. Discute aspectos quantitativos, considera??es ambientais, e oportunidades de P+L nas fases do processo produtivo. Os resultados apontam para economias de insumos sob a forma de alimentos, corretivos de solo, medicamentos, e energia aplicados ao processo, que variam de 4 a 27%, ressaltando-se que o pequeno ganho financeiro, deve ser encarado como uma fonte de consider?vel benef?cio ambiental. Os autores concluem pela propriedade da ado??o da t?cnica neste segmento do agroneg?cio, ressaltando a import?ncia do gerenciamento da dosagem de insumos na qualidade do efluente final, al?m da ado??o de um mecanismo de remedia??o f?sico-qu?mica para o residual de metabissulfito de s?dio utilizado na despesca
