Problem-

The purpose of this experiment was to determine how specifically selected water temperature (2 levels), water salinity (2 levels), and density level of shrimp populations (3 levels) influence the growth rate of shrimp raised in aquaria and whether these factors acted independently on the shrimp populations. The experimental design consisted of three replicate aquaria for each of the 12 treatment combinations. Each of the 12 treatment combinations was randomly assigned to three aquaria. The 36 aquaria were stocked with post-larval shrimp at the beginning of the test. The weight gain of the shrimp in four weeks for each of the 36 aquaria was determined on a per shrimp basis.

Additional information-

The problem related to Basic Statistics and it discuss about factorial design in ANOVA.
