Fish as feed inputs for aquaculture: practices, sustainability and implications

(Romina) #1

Wild fish and other aquatic organisms as feed in aquaculture in Europe 213


Seabass and seabream
aquaculture has developed more
recently and the production of
both species groups has tripled
over the last decade, reaching
around 80 000 tonnes and 97
000 tonnes, respectively, in 2005
(Figures 2 and 4, Table 1). Based
mainly in Greece, Turkey and
Italy, seabass farming expanded
rapidly in the late 1990s but has
steadied since 2000. Seabream
farming, principally of the gilthead
seabream (Sparus aurata), also
showed a brief plateau in the early
2000s but continues to increase,
largely due to the rapid growth of
Turkish production. Both species
groups are mainly farmed in sea
cages in sheltered areas,
although land-based
units are also used in
France and Spain. Italy
traditionally used the
“vallicoltura”^4 system
but has also moved
towards intensive
production in land-
based operations and
marine cage farms.
Without tidal flushing,
cage-farm units in the
Mediterranean Sea
tend to be smaller than
salmon cage farms in
the Atlantic.
The production
of other marine
fish such as turbot,
halibut and cod is
increasing steadily as
technical constraints
are overcome (Figures
2 and 4, Table 1).
Turbot and Dover
sole (Solea solea) are
mostly produced in
land-based farms on
the Atlantic coasts
of Spain and France,
while cod, halibut and
