Abstract : Mycosporine-like amino acids (MAAs) were investigated in two soft coral] species collected during summer and winter of 2003 and 2004 at 5, ID, 15, and 20 m depth. Four different MM..s were detected. Plaything was the dominant compound in Sinularja polydac¬tyla and Sarcophyton trocheliophorum. The palythine concentration in S. trocheliophorum varied from 44 to 141 J.lg mg-I protein in summer compared to 33 to 129 J.lg mg-l protein in winter. The corresponding variation in S. polydactyla was 34 to 187 J.lg mg-I in summer and 24 to 127 J.lg mg-l protein in winter. Both the maxima and minima were higher in summer compared to winter and at all depths. Next to paly¬thine; porphyra-334 was detected in S. trocheliophorum. It was one eigth compared to palythine. The concentration of asterina-330 in S. Irocheliophorum was almost negligible. Mycosporine-glycine was not detected at any depth or season indicating that the organism has passed through the initial evolutionary process. PhotosyDthetically Active Radiation (PAR) was 67% more in summer compared to winter and hence explains the fact that the production of MAAs is more in summer compared to winter indicating that the photosynthetic zone favours the production ofMAAs
