Effect of stocking density on laboratory rearing of mullet fingerlings, Mugil platanus (Günther, 1880)
The effect of stocking density on production of Mugil platanus fingerlings in laboratory was analyzed. Five stocking densities were evaluated: 1, 3, 5, 10 and 15 mullet/L. After 28 days, the highest growth rate was reported for animals reared at the lowest stocking density (1 mullet/L). Survival rat...

| Sumario: | The effect of stocking density on production of Mugil platanus fingerlings in laboratory was analyzed. Five stocking densities were evaluated: 1, 3, 5, 10 and 15 mullet/L. After 28 days, the highest growth rate was reported for animals reared at the lowest stocking density (1 mullet/L). Survival rate and water quality were also higher at the lowest stocking density. Although more fingerlings were produced at 10 mullet/L, greater number of animals decreased the water quality, which was reflected in their reduced growth and survival rates. M. platanus fingerlings should be reared in commercial production at intermediate stocking densities (3-5 mullet/L) but higher water exchange rates are recommended for lower ammonia concentration |
