Field experiments on feeding of European fiddler crab Uca tangeri

Abstract

Investigations were carried out on a mudflat near Ramalhete Creek in the Ria Formosa on the Portuguese Algarve coast. All particles <250 μm were ingested regardless of their chemical composition. U. tangeri feeds primarily on microalgae which are completely extracted from the sediment. It also consumes vascular macrophytes (Arthrocnemum spp.), macroalgae, detritus and fish carcasses. -from Author
