Seasonal fluctuation of photosynthetic pigments of most common red seaweeds species collected from Abu Qir, Alexandria, Egypt

Seasonal changes of pigment composition [Chlorophyll a (Chl-a), total carotenoid (Car.), phycobiliproteins (phycoerythrin (PE), phycocyanin (PC), allophycocyanin (APC))], in the 5 species of Rhodophyta were investigated. Chl-a, carotenoids and phycobiliproteins levels showed high contents during win...
