Kelp harvesting involves collecting seaweed from natural beds or farms using methods that balance productivity with environmental sustainability.
Methods of Harvesting
1. Shoreline Collection (Storm-Cast Kelp): After storms, kelp naturally detaches and washes ashore. This “storm-cast” kelp can be collected by hand without disturbing the marine ecosystem, making it an accessible and low-impact method for small-scale harvesters (Gulf of Maine).

Environmental Considerations
Overharvesting can negatively impact marine life that depends on kelp forests for habitat and food. Sustainable harvesting ensures that kelp forests continue to support biodiversity while providing a renewable resource for human use (Katy ISD).
