Species · the working season on a line farm

Seaweed Farm Operations

Seed, line, season, and harvest: how a kelp farm is actually run, from the nursery string to the wet product leaving the dock.

Six lessons on running a seaweed farm: the season laid out with its unmissable weeks, the site conditions and gear a longline needs, where seed comes from and how short its handling window is, what tending really looks like, the harvest day and the cooling clock that starts at the cut, and the records and gear recovery that close a year properly.

$125 once, or $125 on Driftline. Add $60 and Jules reads and grades one real piece of work, passing at 80 percent. Review is optional. Nothing here is accredited or carries credit.

On your own

The whole class, the practice work, and the knowledge checks. No pass score, no graded work, no certificate gate.

With Jules reading your work

Everything above, plus one real piece of work, "One season on a seaweed farm", that Jules reads and grades against a rubric you can see 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 not accredited and carries no continuing education credit.

What this course covers where you live

We say plainly how well each part of the country is covered, rather than implying the whole country is written to the same depth.

Where the published guidance is thin

Some of this subject has no rule behind it yet. Rather than sounding more certain than the record allows, we say what is missing, point to the newest and best material that does exist, and give you the date we last checked it.

If you want Jules to read your work

Everyone gets the same lessons, practice work, and knowledge checks. For $60 more you also 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 season on a seaweed farm

Plan a season of gear, labour, and harvest, and price the work.

Plan one growing season for a seaweed farm of a size you choose. Give the site and why it suits the crop, the gear and its layout, the calendar from seeding to harvest, the crew at each stage, and what happens to the crop within hours of coming out of the water. Then cost one unit of production, showing your working. Mark every number as either sourced, with a citation, or as your own estimate with the reasoning behind it.

How it is graded

  • Site and crop matched with conditions · 25 points

    Your reasoning uses real conditions for that site, not general suitability.

  • Calendar and crew hold together · 25 points

    The labour at each stage matches the gear and the acreage, and the dates are plausible for the region.

  • Post-harvest handled within the real window · 25 points

    You account for what happens immediately after harvest, because that is where value is lost.

  • Costs traced to one unit · 25 points

    The arithmetic reaches a per-unit cost, and every input is either cited or clearly flagged as your estimate.

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

Siting is its own project. Talk to your state's leasing authority and your Sea Grant program early, and expect federal review for gear placed in navigable water.

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.
