Abstract

The Rhodophyta Division is characterized by having representatives of macroalgae with commercial value due to their phycocolloids. Ahnfeltia plicata It is a macroalgae producing agarose and therefore an opportunity for artisanal fisheries and industry. Natural meadows of A. plicata from Skyring Sound (Magellan Region), display yellow and red variants that should adapt eco-physiologically to environmental conditions of their habitats. The concentration of photosynthetic pigments is one of the parameters used to assess the physiological state of the seaweeds. The objective of this study was to determine the concentrations of chlorophyll a and phycobiliproteins, in the yellow and red variants of A. plicata, inhabiting the Skyring Sound. The pigment extraction was performed using liquid nitrogen and acetone at 90%. The
