Go Clamming


Short Travel


$5 - $10

STEM Connection

Hardshell clams go by a couple of scientific names - bivalve mollusc and  quahaug (pronounced kwa-hog).  Quahaug comes from the Wampanoag indians.  Clams have several sizes, almost like shirt sizes.  Small = countnecks or peanuts, Medium = littlenecks, Large = topnecks, XLG = cherrystones, 2XL = qualhaugs.  In Delaware, you can keep your quahaug if it's at least 1-1/2 inches wide (and assuming it comes from clean water).  When clamming with the kids, using scientific terminology will help them gain comfort in this are of STEM...which will ultimately build confidence in using STEM words in all areas of STEM.

Best Location

There are a couple of GREAT places to go clamming, but our favorite (that almost always delivers) is:

Cape Henlopen Fishing Pier

Cape Henlopen State Park (Lewes Entrance)

Must go to the right of the pier!

Tower Road in Seashore State Park is another good spot, but sometimes clamming is prohibited due to water quality conditions (e.g. big rain storms and algae bloom make the water bad at certain times of the year)

Project Materials List

  • Clamming rake (or small shovel)

  • Bucket

  • Waterproof Gloves

  • Size you don't get arrested

  • Fishing license if you're over 16

These supplies can be found at bait shops, Ace Hardware, and Walmart.  (Walmart has the best prices.)

Ideas, Notes, & Tips

Generally speaking, if you're over 16, you need a license.  Sizes vary by type of fish.  Ask the bait shop if they have a current ruler for fish sizes allowed.  It's a fun take-away for the kids...and it's a great STEM lesson all by itself.
