Our study results show that the optimal harvest time of sea-based cultivated U. Early spring (April) conditions were optimal for obtaining high fatty acid, protein, biochar, phenolic, and pigment contents in the biomass, whereas carbohydrate and ash content, as well as essential and non-essential elements, increased later in the growth season. ![]() The number and size of holes in the thalli and the amount of fertile and fouled tissue increased with prolonged growth season, which together led to a significant decline in both biomass yield and quality during summer (June). The highest biomass yields (approximately 1.2 kg fw –1) were observed in late spring (May). To identify optimal harvest times of Swedish sea-based cultivated sea lettuce ( Ulva fenestrata), this study monitored biomass yield, morphology, chemical composition, fertility, and biofouling at five different harvesting times in April – June 2020. The biochemical profile of sea-grown biomass depends on seasonal variation in environmental factors, and the optimization of harvest time is important for the quality of the produced biomass. ![]() Sea-based cultivation of seaweeds can provide high biomass yields, low construction, operation, and maintenance costs and could offer an environmentally and economically sustainable alternative to land-based cultivations. Seaweed biomass is a renewable resource with multiple applications. 3Fibre and Polymer Technology, KTH Royal Institute of Technology, Stockholm, Sweden.2Division of Food and Nutrition Science, Department of Biology and Biological Engineering, Chalmers University of Technology, Gothenburg, Sweden.1Department of Marine Sciences, University of Gothenburg, Strömstad, Sweden.Schmidt 3† Niklas Wahlström 3† Barbro Kollander 4† Henrik Pavia 1† Ingrid Undeland 2† Gunilla B.
