In situ biodeposition rates of Pacific oysters (Crassostrea gigas) on a marine farm in Southern Tasmania (Australia)

Variation in biodeposition rates were attributed to the time of year and stocking density. Minimal enrichment of the sediment was found under the culture structures indicating that tidal water movement within the intertidal culture area is sufficient to disperse biodeposits. However, the impact of this material being transported and accumulating elsewhere in the lagoon remains unknown.
