Cultures and thermal analysis of the marine microalga Tetraselmis suecica Kylin (Butch).
In this paper, the growth of the marine microalga Tetraselmis suecica was investigated using thermogravimetry (TG) and differential thermal analysis (DTA) to determine suitable diets for larval and juvenile development in aquaculture systems. Microalgae were maintained in synthetic sea water (19@1000 salinity, 18 degrees C constant temperature) and the algal growth was evaluated by cell abundance. Exponential, stationary and senescence cells were analyzed by TG and DTA. The results of thermal analysis pointed out marked differences between exponential, stationary and senescence phases and showed that exponentially growing microalgae could represent a suitable food in aquaculture systems.
