Alkaline phosphatase activities were examined in blooms of N. spumigena Mertens in the Peel-Harvey estuarine system, Western Australia. Variations in phosphatase activity occurred geographically and diurnally, as well as over the duration of a bloom. These variations correlated with differences in the P nutritional status of the Nodularia. In the laboratory, Nodularia phosphatase production was inversely proportional to cellular P, but not to external soluble reactive P.
