“…Freshwater input from the Boco River, particularly during the winter, is more significant relative to the tidal flow in locations away from the Ria de Aveiro inlet [ 21 ]. Short or long-term changes in salinity levels have been shown to affect F. vesiculosus , with lower salinities negatively affecting photosynthesis [ 33 , 34 , 35 ]. It is important to stress that our study provides a snapshot and does not consider seasonal variations.…”

Fucus vesiculosus is a brown seaweed with applications in the food, pharmaceutic, and cosmetic industries. Among its most valuable bioactive compounds are the pigment fucoxanthin and polysaccharides (e.g., fucoidans). In this study, we profiled the photosynthetic pigments and carbohydrates of F. vesiculosus from six locations along the Ílhavo Channel in the Iberian coastal lagoon of Ria de Aveiro, Portugal. Photosynthetic performance (Fv/Fm), pigment, and carbohydrate concentrations were similar between locations, despite differences in environmental factors, such as salinity and periods of exposure to desiccation. Concentration of total carbohydrates (neutral sugars + uronic acids) averaged 418 mg g−1 dw. Fucose was the second most abundant neutral sugar, with an average concentration of 60.7 mg g−1 dw, indicating a high content of fucoidans. Photosynthetic pigments included chlorophylls a and c, β,β-carotene, and the xanthophylls fucoxanthin, violaxanthin, antheraxanthin, and zeaxanthin. Concentrations of fucoxanthin were higher than those reported for most brown macroalgae, averaging 0.58 mg g−1 dw (65% of total carotenoids). This study indicates that F. vesiculosus from Ria de Aveiro is a valuable macroalgal resource for aquaculture companies operating in the region, with considerable potential to yield high-value bioactive compounds.

Influence of environmental factors on the contents of free amino acids in Fucus vesiculosus in the Barents Sea during the day

Influence of main environmental factors (temperature, intensity of photosynthetically active radiation and tidal cycle) on the contents of free amino acids (FAAs) in Fucus vesiculosus in the Barents Sea during the day was investigated. An undular change in the content of FAAs occurs during the day, associated with the phases of the tidal cycle. Temperature and photosynthetically active radiation influenced the content of FAAs, but their relation probably is a nonlinear. The content of most of FAAs and their total amount reached the highest values at a minimum water level. The lowest values were determined when algae were in seawater. The difference in the content of individual FAAs and their common amounts averaged 1.5-3 times during the day. The reason for the changes in the content of FAAs is probably related to the metabolic processes and their switching during the transition of algae from an aquatic environment to an air and vice versa.
