Abstract: Biodeposition method, a recently developed method used in studies on physio-ecological characteristics of bivalval mollusks,including clearance rate (CR), ingestion rate (IR), absorption efficiency (AE) and energy budget, is reviewed in this paper. The method estimates feeding and absorption rates through measurements of suspended particles and biodeposit production. The main assumption of this method is that ingested particulate inorganic matter can be used as an inert tracer of feeding and digestive processes. The method is based on feeding responses that are integrated over long time scales, reducing the variability on the measurements affecting growth parameters associated to instantaneous responses.

Key words: eutrophication, iron, algae growth, microcystin synthesis, ferric uptake regulation protein (Fur).
