Popis: Proximate composition of wild and cultured strains of Palmaria palmata and the effect of temperature, time of harvest and nitrogen deprivation were studied with an emphasis on lipids and fatty acids. Total lipid content of the two strains were 2.0 and 1.8% (dry weight basis), respectively. The cultured strain showed increased accumulation of protein and ash in comparison to the wild strain. Myristic, palmitic and eicosapentaenoic acids (EPA) were major fatty acids in both wild and cultured strains with 18: 1 ω-7 equalling or exceeding the level of myristic acid in the cultured strain. No major trends were noted in unsaturated fatty acids including EPA with time of harvest. The C18 unsaturated fatty acids tended to increase in nitrogen deprived cultures relative to the initial and nitrogen-sufficient controls at 11°C
