Quantitative data on post harvest fish losses using informal data collection techniques.

The paper describes how informal data collection techniques can be used to generate indicative quantitative data on post-harvest fish losses. Over the last two decades a number of systematic yet informal methods of data collection, project identification and evaluation have been developed, and incorporated into approaches such as Rapid Rural Appraisal (RRA). A number of data collection tools are associated with RRA, some of which have been used experimentally by NRI and the Tanzania Fisheries Division for fish loss assessments. Outlined are the data required and a description of the tools used to gather these data. Calculations used to quantify losses over a set period of time in chosen fisheries are presented. The results of this research suggest that the use of informal tools for fish loss assessment should be seen as a valid approach, but that further research is required into the way price data is gathered and used in the measurement of losses.
