This report is a response to the second review of project number R8210, ‘the use of sluice gates for stock enhancement and the diversification of livelihoods’. The project ended in February 2005, but this review was sent to the project team in late July 2005. It is therefore too late to incorporate reviewers’ comments into project reports and project documentation, most of which have already been printed and disseminated. This supplementary report, therefore, aims to address the three main issues raised in the reviewers report and should be read in conjunction with reports already submitted.
