Abstract

Chlorophyll-a, phycoerythrin, phycocyanin and allophycocyanin of the red alga,
Gracilaria edulis, cultured in outdoor tanks under natural light at different depths
were estimated. Crop growth rate and pigment contents in relation to varjdng
light intensities (depth) were observed. An inverse relationship between pigment
content and the light intensity was noted. But growth rate was more at higher
light intensities.
