Abstract
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.
