Abstract
The need to further diversify their production with
the introduction of new, high valued fishes is well
anticipated by fish farmers. To assess the feasibility
of intensively farming four species common in the Mediterranean
sea, these were reared under intensive conditions in
open raceways in Crete. They were all offered the
same commercial diet by self feeding devices for an
extended period, from fry to market size fish. These
species were sharpsnout sea bream (Puntazzo puntazzo
L.), red sea bream (Pagrus pagrus L.), white sea bream
(Diplodus sargus sargus), and annular sea bream (Diplodus
annularis). Their growth performances were compared
with those of gilthead sea bream (Sparus aurata), and
sea bass (Dicentrarchas labrax) already successfully
farmed in the Mediterranean region and which were reared
under the same conditions. The results are discussed
in relation with the feasibility of profitably cultivating
these fishes. It is suggested that red sea bream and
sharpsnout sea bream may be successfully reared, while
the growth rates of while sea bream and annular sea
bream are very slow, thus rendering these species inappropriate
for intensive aquaculture.
