Abstract:(15.24 g±2.9 g) to three kinds of artificial shelters under different . Additionally, we evaluated the effect of rearing),and feeding frequency (1, 2, 3, or 4 mealsper day)(0.50 g±0.02 g) in a 7-week net cage culture experiment. were attracted to all 3 artificial shelters types, but particularly to the shelters constructed of scallop cages (S1). The association of fish with the artificial shelters increased under dark conditions, . As density increased, the final weight, specific growth rate (SGR) all increased. For fish reared in the no shelter group, the DWGR and SGR of the low density group was significant lower than for the medium and high density groups the final weight was significant lower than in the high density group .The availability of artificial shelters was associated with a significant increase in the final weight in the low and medium density groups coefficient of variation for body weight (CV increased with stocking density. The presence of shelters was associated with a lower than in the absence of shelters. The difference was very significant between low and medium density groups (among the groups when the satiation feeding frequency was more than twice per day (, significantly and better growth could be achieved by using artificial shelters in the cultivation environment with a feeding frequency of twice per day.
