Zostera marina
Moliço was particularly important in the coastal lagoon of Ria de Aveiro, on the northern Portuguese coast. There it was collected in large quantity by raking from typical sailing boats called "moliceiro". The most abundant plant was the eelgrass, including "Zostera marina", "Zostera angustifolia" and "Zostera noltei" and some other salt tolerant aquatic plants like "Ruppia" and "Potamogeton".
