The effects of stocking density (30 and 40 fry/m³) and culture methods (mono
or polyculture) on growth performance, survival rate and feed utilization parameters of
sea bass (Dicentrarchus labrax). advanced fry (0.26 g) reared in indoor fiberglass
tanks (0.5 m³ each) were investigated. The fish were fed artificial diet with 48%
protein, two times daily to satiation for 105 days. The results revealed that: 1- Sea
bass advanced fry reared under moderate density (30 fish 1m3) had best growth,
survival rates and feed utilization parameters; 2· Condition factor (K) was not only
affected by high density; 3- Sea bass advanced fry grow better in monocutture than in
poIyculutre with sea bream, SpafUs 8urala, Cannibalism was the main cause of death
(n sea bass and bream 120lyculture conditions; and 4· Stocking 10 golden grey
mullet, UZ8 aurata, per m³ with 20 sea bass advanced fry did not lower sea bass
growth, survival rates and condition factor.
