Özet
In this study, a culture of a red macro algae Gracilaria verrucosa (Hudson) Papenfuss in the continuous water flow indoor 20 lt tank systems with different light intensities was examined. During the study, continuous water exchange was supplied by a water pump from the sea into the tanks. The water flow was recorded as 1. 44 m(3).day(-1). Daily 12 hrs illumination and 12 hrs dark photo-period cycle was applied above the water surface area in the tanks. During the illumination period, 1000 and 3000 lux light intensities were supplied. During the 3-month study period between November 2002 and January 2003, the water temperature was ranged between 8.7 and 20 degrees C. During the experiement G. verrucosa biomass and water quality parameters were measured and recorded periodically. From the result of study, it was concluded that the light intensity and temperature affected growth of algae, and there was no significant differences recorded between the algal growth measured grown at 1000 lux and 3000 lux light intensities, even algal growth was measured higher at 3000 lux light intensity.
