Abstract
Marine fish. sea bass (Dicentrarchus labrax). sea bream (Sparus 8urata) and
mullet demonstrated the most important fish species in maricullure programs not only
in Egypt. bot also in Mediterranean countries. Sea bass and breams. the main species
produced. experienced the highest increase in all of key Mediterranean species.
Mediterranean offshore mariculture is seen as a way to increase fish production in
areas where it would otherwise not be possible, and fulfill the lack between the
demands and the production of fish in Egypt.
six experimental diets were formulated; a fish meal based control diet
and five diets in which 25 % of the fish meal was substituted with either algae,liver of
cartilages. clams and liver of beef or shrimp meal (diet 2. 3,4,5 and 6.respectively).
The diets were fed to sea bass post larvae (Dicentrarchu$labrsx) over a 105-day
experimental test period. Growth performance, survival rate and feed utilization
parameters . The besl in fish fed diet (3) containing 22% liver of cartilages, followed
by fish fed diet 5,6,4,1 and 2 respectively. Considerable saving in feed costs was
achieved when liver of cartilages was used as a partial dietary substitute inside
fishmeal within compound feeds for sea bass post larvae statga, about 22.7%.
