The global farming of fish and shellfish has been the fastest
growing food producing sector in the last few decades and
has become an important industry in many countries. Fishmeal
made from pelagic fish used to be the major dietary protein
source in compounded feed for many important farmed species,
but the limited amount available has resulted in massive
research to identify alternative protein sources. The average
levels of pelagic fishmeal in aquaculture feed have decreased
substantially in the last decade and recent published results in
the scientific literature show that it is possible to replace even
more in diets both for carnivorous and herbivorous/omnivorous
species. If the predicted low inclusion levels are reached
in the next decade, there may be room for a relatively large increase
in the total production of farmed fish and shellfish without
any increased use of fishmeal.
