Part 1 - How to start a Clamming business - Background
Clams are a highly popular shellfish that people enjoy in many dishes. They appear in everything from inexpensive fried clam baskets to pricey trays of clams casino, not to mention the clam chowder that many New Englanders and New Yorkers grow up on.
Many of the clams that people eat are harvested by small business owners who dig for clams in dirt and mud along the shoreline. While there are some boats that fish for clams in deeper waters, small clamming businesses dig and rake up millions of pounds of clams every year.
Our guide is in 3 parts:
- Part 1 - How to start a Clamming business - Background
- Part 2 - Our planner tool to see if this idea is the right fit for you
- Part 3 - Action plan to get started
What are the costs involved in opening a clamming business?
The costs associated with opening a clamming business are minimal. Business owners need:
-
A commercial shellfish license
-
A metal gauge for measuring clams
-
A few 5-gallon buckets
-
Footwear that offers protection (wetsuit shoes work well)
If desired, a rake, inner tube and rolling machine (for sorting) may also be purchased. Even with these items, it’s often possible to outfit a clamming business for just a few hundred dollars including any necessary licenses.
Business owners who need a boat to reach clamming grounds will have to spend more, but a used rowboat or skiff suffices and doesn’t cost much.
What are the ongoing expenses for a clamming business?
The ongoing expenses for a clamming business are almost nothing. If a business has a powerboat, then fuel and oil must be purchased. Otherwise, the only main ongoing expense is whatever annual fee must be paid to keep licenses current.
Who is the target market?
Clams eventually make their way to seafood shops, grocery stores and restaurants. Clamming businesses, however, sell to clam wholesalers who are middlemen in the supply chain.
How does a clamming business make money?
Once clams are sorted, they’re sold to a wholesaler in the area. Most clamming regions have only one or two wholesalers.
How much can you charge customers?
The wholesale price of clams is determined by the market. Most clams sell for around $2.25 per pound, but littlenecks can command higher prices.
How much profit can a clamming business make?
Business owners can earn between $100 and $200 per half-day of work. Exactly how much business owners make depends on how hard they work and how plentiful the clams are.
How can you make your business more profitable?
In addition to harvesting clams, business owners may also be able to gather certain crabs or mussels that they come across while working. These won’t be major income streams, but they can provide a little boost if there’s someone in the area who will buy them.
Day-to-Day and Growth
What happens during a typical day at a clamming business?
A clamming business owners’ day is dictated by low tide, as Luke Jenks explains. Luke and his clamming partner Mike start their day 2 to 2.5 hours before low tide and continue working until 2 to 2.5 hours after low tide. Outside of this time frame, the water is too deep to work effectively. Most clammers don’t work in the middle of the night, which is why work is limited each day.
After arriving at a clamming location by foot or boat, business owners begin searching for clams. Luke feels around for them with his feet, but others use rakes or shovels (see Jump-Starting). Once clams are gathered, they’re put into a bucket and sorted at the end of the day. Many clammers use an innertube to stabilize and move the bucket. Sorting can be done by hand or with a mechanical sorter.
What are some skills and experiences that will help you build a successful clamming business?
Running a clamming business requires little more than knowing how to find and harvest clams.
There are classes on clamming (e.g. The University of Rhode Island offer courses), but taking a course is often unnecessary. Business owners can usually find a fellow clammer in the area who will teach them the tricks of the trade and not charge a fee for doing so.
Those who don’t have a mentor or want additional information can read books, such as The Compleat Clammer and Here’s How To… Clamming.
What is the growth potential for a clamming business?
Clamming businesses remain small, and most are one-person operations. There are few barriers to prevent would-be employees from establishing their own businesses, and the profit margin often doesn’t justify hiring employees. Additionally, work in many states is seasonal.
What are some insider tips for jump starting a clamming business?
How much a clamming business makes depends directly on how many clams are harvested. There are several ways to harvest, and which is the most effective depends on what type of clams are being harvested and what the harvesting area is like. The main techniques are:
-
Treading (feeling for clams with the feet and then picking them up by hand)
-
Raking (using a rake with a wire basket attached to collect clams)
-
Shinicocking (another type of raking)
-
Digging (using a shovel akin to a post-hole digger to get “digger clams”)
How and when to build a team
Most clamming business owners don’t hire employees. A few may work with family members, but these working relationships are generally more like a family business than a typical employer-employee arrangement.

Part 3 - Action plan to launch your Clamming business in 90 days
Nine concrete steps to take you from idea to open business, grouped into 30-day phases. Complete the planner above and we'll highlight what's most important for your situation.
First 30 days — Foundation
-
Form your legal entity
An LLC keeps your personal assets separate from business debts and lawsuits — the most common reason small business owners choose this structure. Sole proprietorships and partnerships do not provide this protection.
-
Get an EIN and register for taxes
Apply for your free Employer Identification Number through the IRS, then register for any state or local taxes that apply to your business (sales tax, franchise tax).
-
Open a business bank account and credit card
A dedicated business account is required to maintain personal asset protection. Mixing personal and business finances ('piercing the corporate veil') can void your LLC's liability shield.
-
Set up business accounting
Recording expenses and income from day one makes tax filing easier and lets you see when the business is actually profitable. Use software (QuickBooks, Wave) or a part-time bookkeeper.
Days 30–60 — Compliance & Risk
-
Get permits and licenses
State and local requirements vary widely. Brick-and-mortar businesses typically need a Certificate of Occupancy; service businesses may need specific professional licensing; food businesses need health permits.
-
Get business insurance
General Liability Insurance is the most common starting point. If you'll have employees, most states require Workers' Compensation. Specific industries need additional coverage (product liability, professional liability, etc.).
Days 60–90 — Launch
-
Define your brand
Your brand is how customers perceive and remember you. A clear name, logo, and visual identity make every later marketing decision easier and protect you legally as you grow.
-
Create your business website
Every legitimate business needs a website. Social media pages are not a substitute — you don't own the platform. Modern website builders mean you can launch a clean site in a weekend without a developer.
-
Set up your business phone system
A dedicated business number keeps your personal life private, makes the business look legitimate, and lets you route calls professionally. Cloud phone services start under $20/month.
