Abstract
Effect of two levels (low and high) of salinity (20 and 35 ppt), light inte nsity (26 and 72 mu E-a m(-2) s(-1).) and nitrogen source (as nitrate and a mmonia) on growth rates, chlorophyll a and b, carotenoids, protein, carbohy drate and lipid composition of Ulva fasciata were studied in a 3x2 factoria l laboratory experiment. Specific growth rate (SGR) was maximum at high lig ht intensity and high salinity. Low light intensity and high salinity enhan ce the accumulation of pigments, protein, carbohydrate and lipid contents; Ammonium in the form of NH4SO4 is relatively better nitrogen source for max imum growth and biochemical composition of Ulva fasciata.
