Utilizing Dredged Sediment for Enhancing Growth of Eelgrass in Artificially Prepared Substrates
Abstract:Dredged sediment (DS) was utilized as source of silt-clay and organic matter in artificially prepared eelgrass substrates with mountain sand (MS) as the sand media. Addition of DS showed improved growth of eelgrass in the mixed substrates. Increase in added DS up to 15% silt-clay showed increased shoot growth but additional DS in 20% silt-clay mixture didn-t result to further increase in eelgrass growth. Improved root establishment were also found for plants in pots with added DS as shown by the increased resistance to uprooting, increased number of rhizome nodes and longer roots. Results demonstrated that addition of DS may be beneficial to eelgrass up to a certain extent only and too much of it might be harmful to eelgrass plants.
