Abstract

Feeding of males and females of the Gammaridea Hyate media at mature and immature stages were tested in laboratory experiments. Macro and microscopic algae as well as dead or alive animals were utilized as food. This gammarid is omnivorous, feeding by predation, scavenging, browsing and scraping. Feeding behaviour was discontinuous. Padina vickersiae was more utilized in winter and Ulva fasciata in summer. The feeding activity of all the animals showed great variability in relation to the type of food. Higher temperatures probably account for the higher consumption observed in summer.
