2.6. Statistical analysis
Statistical analysis was conducted using SPSS 13.0. Data as percentages
were arcsine transformed to obtain normality prior to
analysis but presented as non-transformed data. Differences in
nutrient concentrations in the control site and fish farm at each
sampling period were analyzed with Student’s t-test. Differences
in the growth rates and tissue nutrient contents of the seaweeds
between the two sampling sites were analyzed with one-way ANOVA,
followed by the Duncan’s test for multiple comparisons. Statistical
significance was set at p < 0.05.
