An experiment was conducted to investigate the effects of stocking density (SD) on growth performance and survival rate in golden grey mullet (Liza aurata). Liza aurata fingerlings (mean body weight 7.44±0.34g) were reared in 9 floating cages at Alsen fish farm for 6 months (May-October 2008). Each cage was covered by two-folded net with mesh size of 5 mm and the total water volume was 1m3. Fish were divided into 3 SDs (20, 40, & 80 fish/m3). Fish groups were fed daily with a unified crude protein diet (40%). Fish samples were taken randomly 1/15 days. Mean body weight (W), weight gain (Wg), daily growth rate (DGR), specific growth rate (SGR), survival rate (S), feed efficiency rate (FER) and the protein efficiency rate (PER) of fish in each group was calculated at the end of each sample period. Highest body weight values were obtained from 40 fish/m3 SD (120.33±5.65 g). Best values of growth parameters (W, WG, DGR, SGR, FER & PER) were obtained from (40 fish/m3) SD. (40 fish/m3) and (20 fish/m3) SDs did not significant differ (p>0.05). But, parameters' Values were significantly lower (p<0.05) in (80 fish/m3) SD. The (40 fish/m3) SD achieved survival rate of 96%, but did not significantly differ (p>0.05) from (20 fish/m3) SD. The use of (40 fish/m3) SD for liza aurata's culture in floating cages in coastal ponds is recommended.
