The maxima of cyanobacterial wet weight biomass were 61.4 and 7.2 g nr2
monthly averages in 1994 and 1995, respectively (Table V). During the bloom
period in 1994, the cyanobiomass (wet weight, weekly data; Table IV) varied
between 1.4 and 82.7 g nr2
, contributing 4.1-88.4% of the total phytoplankton
biomass. During the same period in 1995, the weekly cyanobiomass varied
between 0.9 and 9.6 g nr2
, representing only 1.9-22.4% of the total phytoplankton
biomass.
The specific net growth rate (K) of the A.ovalisporum population in the lake
varied from 0.02 to 0.30 In units day1
from August to mid-October 1994 and from
0.06 to 0.40 In units day1
in 1995, corresponding to a doubling time of 2.3-5 days
(with a maximum of 21 days) during the stationary phase in 1994, and a doubling
time of 1.7-3 days in 1995.
