Seaweed Cultivation Laboratory Testing: Effects of Nutrients on Growth Rate of Ulva intestinalis

Abstract New seaweed cultivation laboratory was developed and primary laboratory bench was tested if the conditions are relevant for seaweed cultivation. Simple experiment was carried out using Ulva intestinalis as test organism. Different nutrient levels were provided to see, which amount of nutrient is the best for cultivation of U. intestinalis. Experiment results showed that best growth rate for Ulva intestinalis was on concentration 2 ml L –1 where growth rate reached on average 7.13 ± 3.44% per day. Higher nutrient amounts slow down algae growth.
