2.4 Statistical Analysis<br />
All statistical analyses were per<strong>for</strong>med using statistical package Minitab 14.0. Pearson correlations<br />
were used to evaluate the relation between water quality parameters and growth. Significance was<br />
compared using two tail two sample student t-test.<br />
3. Results and Discussion<br />
The trials clearly showed that <strong>fisher</strong> folk are capable of implementing the technology of Gracilaria<br />
farming by them. At 45 days to a month old, branches of seaweeds start to fall off due to the water<br />
current. In order to save them from drifting away, nylon net should be placed as a fence around the<br />
area that is perpendicular to the water current. There is a strong Pearson correlation between the<br />
Growth Rate of Gracilaria and salinity, DO, while no positive correlation found were found<br />
between other variables.<br />
