Abstract
The effect of additional nutrients and varying stocking densities (500, 1000, and 2000 g m-2) on the growth and physical properties of Gracilariopsis bailinae was determined. Growth was significantly higher (L = 0.05) at a stocking density of 500g both in enriched (3.5%/day) and unenriched (1.9%/day) treatment, but growth was not significantly different between 1000 and 2000g density. A decreasing growth rate was observed with increasing stocking density. Significant differences in gel strength and gelling temperatures were observed only at 2000 g m-2 both in enriched and unenriched treatment. Results of the study showed that additional nutrients are necessary for the growth of G. bailinae and its agar quality.
