Shellfish 101
A friendly introduction to bivalves, crustaceans, abalone, sea urchins, and other shelled invertebrates: how growing waters are classified, how closures work, and how to farm or forage without leaving a mess behind.
Six lessons take you from telling a bivalve from a crustacean to checking your own state's closure source before you ever pick anything up. The safety rules are the heart of it, and we show you where each state actually publishes them.

Alaska: aquatic farm leases run through Natural Resources and Fish and Game
An Alaska aquatic farm needs a state land lease from the Division of Mining, Land and Water and an operation permit from Fish and Game. The two applications travel together, so read both before you pick a site.
Alaska Division of Mining, Land and Water, Aquatic Farm Leasing Application Process · checked 2026-09-19Northeast: leases are state by state, and Maine publishes the clearest path
Maine's Department of Marine Resources posts its standard lease applications and forms in full. Massachusetts, Rhode Island, and Connecticut each run their own process through their marine or agriculture agency, so start with your own state's page.

Rhode Island reviews aquaculture through the Coastal Resources Management Council, and Connecticut runs shellfish through the Department of Agriculture's Bureau of Aquaculture. Both publish current application steps.

If you want Jules to read your work
Everyone gets the same lessons, practice work, and knowledge checks. Add review for $60 at the regular rate or $40 at the openly offered Driftline rate. You get one real assignment that Jules reads and grades. You can see exactly how it is judged before you start, you pass at 80 percent, and you can rewrite and send it back as many times as you need. This is optional, and it is still not accredited and carries no continuing education credit.
The assignment
One growing area, start to finish
Trace a real shellfish growing area and what governs it.
Pick a classified shellfish growing area in any coastal state. Explain: where it is and what is grown there; how the state classifies it and what that classification allows; what closes it and who announces closures; how someone harvesting there would know the status on a given morning; and what the rules require after harvest. Cite each state page with the date you checked. Where the state does not publish live status, say so and describe what a harvester does instead.
How it is graded
The area and its classification stated correctly · 25 points
Classification, and what it permits, match the state's own published wording.
Closure triggers named · 25 points
Biotoxin, rainfall, or pollution triggers are described as that state actually defines them, with the notifying office named.
A workable morning check · 25 points
Your description of how a harvester confirms status is something a person could really do, including a phone line if that is what exists.
Post-harvest handling included · 25 points
Tagging, temperature, and time requirements are present and traced to the rule that sets them.
100 points in total. You pass at 80. Jules grades what you worked out, not your formatting or your word count.
Where it can take you
The final lesson points to restoration and shellfish gardening projects, working farms that take seasonal help, regional Sea Grant and extension programs, the deeper hatchery and nearshore courses here, and college programs when credit and supervised hours are what you need.
This course does not carry accreditation, credit, or continuing education units, and completing it does not count toward any outside credential. It is written to the structure a continuing education standard expects, with measured hours, written outcomes, and a completion record you can keep.
