Tilapia growth performance
The individual mean weight of fish by tank at the end of the experiment in Treatment Two with middle fish density was (28.6±0.59 g), whereas, the mean fish weight in the low and high densities Treatments One and Three were 25.5±0.59, and 27.7±0.72 g, respectively.
The Feed Conversion Ratio (FCR) found in T2 was 1.85±0.01, 1.89±0.02 in T3 and 2.05±0.03 in T1, respectively.
Shrimp growth performance
At harvest, the mean individual weights of shrimp per tank were 9.7±0.87, 11.1±0.88 and 10.5±0.83 g for the Treatments One, Two and Three, respectively. The FCR of shrimp was 1.63± 0.02 in T2, 1.70± 0.01 in T3 and 1.73±0.01 in T1 (Table 2).
