• The growth rates of naturally attached micro-algae were determined at both species and whole community levels in Ago Bay during November and December, 1982 by dialysis culture technique under in situ environmental conditions.The growth rate of the whole communities were between 0.25 and 0.66 day-1 at 1m, and mostly decreased with the depth. On the other hand, the growth rate of each species varied greatly, for example, 1.04 day-1 in Nitzschia longissima to -0.07 in Stauroneis sp. at 1m, and mostly decreased with the depth.The depth profiles of the growth rates for the whole community and each species mentioned above seemed to generally show light-saturation near the surface. However, some species presented greater rates in the middle layer (3-7m) than the surface.
