Abstract
Aquatic plant shoots are transplanted by positioning shoots, plants or seeds in a sediment tube or sediment bag which is in turn placed in a propeller scar or blowout.The sediment tubes and sediment bags may be preformed or they may be formed just prior to their placement in the estuary.With the process and apparatus of this invention, sea grass shoots, plants and seeds can be replanted on the bottom of an estuary and new plant growth encouraged in propeller scars and blowouts.The material from which the sediment tube or bag is formed from degrades. The degradation of the sediment tube or bag can be correlated to the growing cycle of seagrass plants, shoots or seeds as may be contained in the sediment tube or bag.
