9 Future Trends in Aquaculture Production
277
almost 90 NOK/kg in the mid-1980s to about 22 NOK/kg in 2004. The story is the
same, on a more limited scale, for other salmonides like coho and salmon trout. It
is also similar for sea bass, sea bream, catfish and tilapia, although the strength of
the price decline varies (Asche et al. 2001).
It is worth noting that the price reductions are not necessarily immediate. When
the aquaculture species is first introduced, there often seems to be an early period
when demand is increasing faster than supply and prices are actually increasing.
