Abstrakt: For the first time with Gracilariopsis bailinae Zhang et Xia, outplanting of laboratory-generated sporelings was undertaken. Young sporelings of the species were planted 1.0 and 2.0 m below the lowest tide level, using the monoline method (fixed to the bottom), off Amunitan,Gonzaga, Cagayan, northern Philippines from February to March 1996. After six weeks of culture at 1.0 m depth, sporelings from which the apices had been removed grew significantly faster than did intact sporelings or sporelings at 2.0 m depth. The maximum growth rate (9.7% d-1) was obtained for sporelings with cut apices grown at 1.0 m below the lowest tide level during the third week of culture period and the lowest (2.6% d-1) was attained for uncut sporelings cultured 2.0 m below the lowest tide level during the first week.
