Our field guide "Common seaweeds on New Hampshire shores" features different types of local seaweeds, images for identifying, seasonal availability, and likely intertidal location. If you have an interest in foraging for seaweed, check out our Seaweed Mania! workshops, listed at the bottom of this page.

Foraging Tips:

• 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% 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, and remember to enjoy!
