1. Introduction
High-priced fishery products are becoming increasingly
scant or even nearly unavailable in developing countries
by effect of the massive overexploitation of some species.
However, the demand for fish in both developed and developing
countries continues to rise. As a result, the only
choice for some is the use of previously scarcely accepted
fish species with many bones, very soft muscle, a very small
size or a very high content in fat. Such species, which,
based on recent reports from FAO, account for roughly
50% of all industrial catches, have traditionally been
rejected for marketing. Making them species acceptable
for consumers entails their prior technological processing
in order to alter their appearance; this usually involves
extracting their muscle and transforming it in order to
