Breeding of shrimp Metapenaeus affinis in submersible cages (SC) and floating cages (FC). Grown were with an average initial weight of 2.350 ± 0.636 and 2.383 ± 0.400, which were fed on the industrial diet prepared for 45 days. Some growth measures as follows (FC and SC): weight increase (g) 1.880 ± 0.170 and 0.884 ± 0.011. Daily growth rate (% g/day) 0.042 ± 0.004 and 0.020 ± 0.001. Feed conversion rate 2.476 ± 0.487 and 1.462 ± 0.350, relative growth rate (%) 82.031 ± 14.993 and 38.008 ± 6.858. While its survival rate (%) was 90 ± 7.071 and 75 ± 7.071, all this respectively. Some environmental conditions measures were temperature (°C)= 27.667± 3.055, salinity (mg/l)=1.603± 0.329, pH=7.783± 0.226, dissolved oxygen (mg/l)= 6.863 ± 0.228. The results of the statistical analysis showed significant (P < 0.05) differences in FCR and in RGR between the shrimp cultured in the SC and FC, while there were no significant differences in the rates of daily growth and increase in weight and survival rates and weekly weight.
