Sun-drying methods

Drying on rocks

The traditional practice of drying fish in the Galapagos is to spread them on the black lava rocks that abound in the islands. No steps are taken to protect the fish from contact with birds, flies and other pests.

A bed of black rocks was therefore assembled and used in the local manner.

Rack drying

This simple and effective improvement on traditional techniques has been brought into use in recent years in various countries such as Malawi. It consists of an inclined perforated rack supported on a simple framework; it affords some protection of the fish against crawling pests and contamination with dust, but not against flies. The rack built for this exercise was made from black plastic mesh and bamboo poles. Materials, other than plastic mesh, that would allow a virtually unrestricted air movement around the rack could have been used; chicken wire would be one alternative. The drying rack was approximately 1m above the ground.
