Note
The effects of 33, 25 and 17‰ salinity on the productivity and agar production of Gracilaria verrucosa Strain G-16 were compared during three distinct temperature periods in greenhouse cultivation trials. Salinities of 17‰ consistently resulted in low productivity and low agar gel strengths. The experimental periods which encompassed environmental extremes in seasonal temperature changes also showed significant differences in productivity, agar yield, and agar gel strength.
