This field guide features names and images for identifying common seaweeds on New Hampshire shores.
Common Seaweeds Seasonality and intertidal location
- When foraging seaweeds for personal use, be aware of pertinent state regulations, do your research and use common sense when looking for safe, clean sites to harvest.
- Harvest each organism in a way that allows it to regenerate and reproduce. Do not pull seaweeds or damage or remove them by their holdfast. Never harvest more than 25 percent of the seaweed in a stand. Depending on the species of seaweed you are harvesting, only cut the tips.
- Look for fresh, healthy, "floating" seaweeds, as these are easier to collect and still edible
- Do not go to the same harvesting site repeatedly; give the site time to recover.
Always use what you collect
Never collect more than you can use.
