Abstract

Seaweeds are recognized as sustainable food sources rich in nutrients and bioactive compounds, but their composition is highly influenced by seasonality. This study evaluated the biochemical profiles of Ulva sp., Fucus vesiculosus, Porphyra dioica, and Palmaria palmata cultivated in integrated multitrophic aquaculture across different seasons. Results showed marked seasonal and species-specific fluctuations. Porphyra exhibited the highest protein content, except in spring. Ulva was richer in lipids and magnesium across all seasons. Palmaria displayed lowest sodium-to-potassium ratios (
