Abstract: Seaweed based Integrated Multi-Trophic Aquaculture (IMTA) systems are being \ndesigned to mitigate the environmental problems caused by several forms of fed \naquaculture. A seaweed cultivation system using 127 and 230 L tanks was used to \ncultivate Palmaria palmata (Rhodophyta). Palmaria palmata is a cold temperate species \nof the North Atlantic and North Pacific Oceans. In the present study Palmaria palmata \ncould grow throughout the entire course of the experiment and under all conditions tested. \nThe highest RGR value (3,13 % ± 0,40) was observed from Palmaria palmata cultivated \nunder a density of 1 kg m-2. Under winter conditions the productivity value reach the \nmaximal value of 26,89 ± 19,02 g(dw) m-2 week−1. The total lipid, protein, ash, \ncarbohydrates and individual fatty acid contents of Palmaria palmata were determined \n(fatty acids by gas chromatography). Total lipid content ranged from 0,00389 ± 0,0003 \nto 0,00987 ± 0,00030 (% ± se). The most abundant fatty acids were C16:0, C18:0 and \nC20:5. Ash content ranged from 14,5 ± 0,67 to 24,2 ± 0,86 (% ± se), protein content from \n17,3 ± 0,05 to 24,8 ± 0,02 (% ± se) and carbohydrates from 55,52 to 67,56%.
