Abstract:
The cultivation of the red seaweed Gracilaria sp. was conducted throughout a
culture period of 8 weeks in a pond in Pusat Penyelidikan Temakan Air Payau (PPTAP),
Gelang Patah, Johore. This cultivation was carried out using 2 different methods which
were the line culture method and cage culture method. During the culture period, the
relative growth rate (RGR, % day ·1 ) of Gracilaria sp. for both methods was monitored
weekly. Growth rates at 3 different depths (top, middle, bottom) for line culture method
were also monitored. At the end of the culture period the Gracilaria sp. was harvested
and extracted to determine the agar quality of Gracilaria sp.
