Abstract:
Four macroalgae (Ulva lactuca, Fucus vesiculosus, Gracilaria, Ceramium) from the tideland of Sylt (Germany) were cultivated over a period of four weeks in an open pond system. The water temperature averaged 15 °C in all aquaria and was kept constant by a cooling system. The specific growth rates of algae were calculated by measuring the fresh weight once a week. The green alga Ulva lactuca had a broad optimum in the second week in two different trials (3.82–3.94 % FW/d). A growth rate peak in the second week (4.36 % FW/d) was also produced with the Gracilaria and Ceramium in the second cultivation experiment, which had less initial weight than the first. However, their fastest growth occurred in the first trial in the first week, with a 4.60 % increase per day. The specific growth rates of Fucus vesiculosus ranged from 0.35–0.95 % FW/d, and the maxima growth rates always occurred in the first seven days of cultivation.
