(introduction...)

The emphasis in this chapter is to present a method of economic evaluation of some of the processes discussed in the preceding chapters. The analysis is predominantly at the level of the small-scale producer using relatively simple and labour-intensive techniques. However, for purpose of comparison, consideration is also given to unit production costs obtained in large-scale plants which use more complex technologies (e.g. canning). Some of the wider issues involved in choosing between small-and large-scale processes are also discussed.

The analysis shows a comparison of costs and the structure of the latter. A pro forma schedule of costs is outlined whereby it should be possible to use local cost data to make calculations on a similar basis to those given. Whilst the main thrust of the discussion is concerned with the assessment of unit costs of production, the implications of any variation in the quality of product and consequently of sales prices are also discussed. The last section of this chapter compares labour requirements for alternative processing technologies and provides a few suggestions regarding the training of labour and the provision of assistance to the small-scale fisheries sector.
