This booklet describes, in a non-technical manner, some important aspects of FAO Technical Guidelines for Responsible Fisheries No. 5 dealing with aquaculture development. The purpose of this booklet is to help familiarize FAO Members and other stakeholders with the goals and practices of responsible aquaculture development. The booklet does not replace Technical Guidelines No. 5 but simply presents some of the complex information contained in those guidelines in a simplified form in an attempt to make it more accessible to all those involved in aquaculture development.
