FILTER-FEEDING SHRIMPS (ANOSTRACA) GRAZING ON BACTERIA

FILTER-FEEDING SHRIMPS (ANOSTRACA) GRAZING ON BACTERIA and Several attempts have been made to cul- ture anostracans. Until recently, anostracans were mainly fed algae (Mitchell, 1991; Bren- donck, 1993; Ali and Dumont, 1995) and agricultural waste products (Platon et al., 1987; Lavens et al., 1987; Ali and Bren- donck, 1995). Ephemeral argilotrophic (rich in clay particles) waterbodies usually contain low amounts of algae, because sunlight can- not penetrate deep into the water.
