This document has been prepared based on sound scientific principles and international approaches to monitoring cage aquaculture facilities. In general this is a guide to help support good monitoring practice, with details on what to monitor, parameters to be collected, how data is collected, appropriate ways to process the data and what to do with it once the survey is complete and results available. Such monitoring activity will ensure that cage farms use practices that minimize environmental impacts for the long term sustainability of cage aquaculture within the Kingdom of Saudi Arabia. In this sense the document is for fish farmers and their consultants to ensure a unified process of monitoring using standardized procedures, but is more generally applicable for all stakeholders.
