Effects of algal food concentration and body size on the ingestion rates of Ruditapes decusata (Bivalvia)veliger larvae
Feeding rates of Ruditapes decusata clam larvae from the D-shaped stage to metamorphosis were recorded at algal food concentrations ranging between 10 to 300 Isochrisys galbana cells/ul. The ingestion rate was directly related to food concentration up to an optimum at 200 cells/ul, beyond which it r...

| Resumo: | Feeding rates of Ruditapes decusata clam larvae from the D-shaped stage to metamorphosis were recorded at algal food concentrations ranging between 10 to 300 Isochrisys galbana cells/ul. The ingestion rate was directly related to food concentration up to an optimum at 200 cells/ul, beyond which it remained almost constant. The response of the ingestion rate to particle concentration could be described by assuming increasing interference among particles that reduces the efficiency of capture by R. decussatus of algal cells. |
