Abstract
Sea bass. Oicentrarchus labrax, fingerlings (1.11 g) were stocked in 240 m3 cages (4 x 3x 2.5 m each, equal 30 rr,l) placed in West·Northem Shore I)f Mediterranean, West Lagoon, Matrouh Governorate, Egypt. to assess the responses of sea bass to rear in intensive (50 fiShlm~ or sernl-lntenslve moooculture (35.8 f1ahlm; or poIyeuliure with golden grey mullet. LiZB aurata, 0( sea bream. Sperus aurala (715 sea bass+360 mullet or sea bream/cage, 30 m1. The fish were handly fed on artificial diet (34.6 % protein) in wet form at a rate of 3-5% of the live body weight, two Umes daily, in addition to 1 % trash fish one time daily, for 323 days. Growth, survival, feed utilization and net produC1ion were depressed with increasing densit~.
, Final weight recorded wele 172.29 g and 128.919 at a density 35.8 and 50 fish 1m , respectively. The best fish performance and economic were achieved in sea bass -seml·intensive monoculture and polyculture with mullet. The total fish production were varied between 4.77·5.40 Kglm' and the payback period between 0.74·1.01 years.
