What is gross stock?

Gross stock is the starting number for every crew share calculation. It is the total dollar value of your catch as recorded on your fish ticket - the weight of fish delivered multiplied by the ex-vessel price the processor paid you.

Example: You deliver 47,000 pounds of sockeye salmon to Peter Pan Seafoods in Naknek. The ex-vessel price is $1.05 per pound. Your gross stock is $49,350.

If you made multiple deliveries on the same trip, gross stock is the sum of all fish tickets for that trip.

Gross stock is the number at the bottom of your fish ticket - the total before any deductions. This is where every calculation starts. If you get this number wrong, every crew member's pay is wrong.

What are shared expenses?

Shared expenses are costs that get deducted from gross stock before the vessel and crew split the remainder. Which expenses are shared - and which the vessel absorbs alone - depends on your crew agreement.

ExpenseShared or Vessel-OnlyNotes
Fuel (diesel)Often sharedMust be in crew agreement
IceOften sharedVaries by fishery
BaitOften sharedCommon in salmon
Observer feesVessel-onlyCaptain pays in most cases
Processor feesVessel-onlyNot deducted before split
IFQ cost recoveryVessel-onlyDeducted from vessel share
The IRS requires that shared expense deductions be documented in writing before the trip - not agreed to verbally after. A crew agreement or a printed settlement sheet with the deductions listed is your protection in a dispute.

How the vessel share works

After shared expenses are deducted from gross stock, the remaining amount - called net stock - is split between the vessel and the crew. The vessel's cut is called the vessel share.

The vessel share pays for fixed costs the vessel owner carries: insurance, loan payments, maintenance, depreciation, and permits.

Bristol Bay Salmon
50%

Equal split. Gross stock minus shared expenses, split 50/50 between vessel and crew.

Alaska King Crab
55–60%

Vessel takes a larger share due to permit and quota costs. Crew pool is 40–45% of net stock.

Dungeness Crab
45–50%

Varies by region and vessel. Pacific coast boats commonly run 50%.

Pacific Halibut
50–55%

IFQ quota costs often increase vessel share. Verify your specific agreement.

Gulf Shrimp
50%

Standard equal split is most common in Gulf shrimp fisheries.

How the crew pool is divided

The crew pool is what's left after the vessel takes its share. This is the total amount available to pay all crew members combined.

Crew Pool = Net Stock × (1 − Vessel Share %)

Once you have the crew pool, you divide it by the total number of share units across your entire crew. The result is the dollar value of one share unit. Every crew member gets paid based on how many share units they hold.

Value Per Share Unit = Crew Pool ÷ Total Share Units
Individual Pay        = Value Per Share Unit × Crew Member's Share Units

Understanding share units

Share units are how commercial fishing distributes the crew pool unevenly - rewarding experience, responsibility, and specialized skills.

PositionStandard Share UnitsNotes
Captain (fishing)1.0–2.0 extraOn top of vessel share
Engineer1.5Machinery responsibility
Experienced hand1.0–1.25Varies by vessel
Standard deckhand1.0Base share
Greenhorn0.75First-season crew member
Cook (if crew)0.5–1.0Sometimes flat rate instead
Share units are negotiated before the season, not after. The captain sets them and they should appear in the crew agreement. Changing share units after a trip to alter someone's pay is a dispute waiting to happen.

The full calculation, step by step

Here is the complete sequence for every crew share calculation:

  1. 1
    Start with gross stock
    The total fish ticket value for the trip.
  2. 2
    Subtract shared expenses
    Only expenses documented in the crew agreement. Result: Net stock.
  3. 3
    Calculate vessel share
    Net Stock × Vessel Share % = Vessel Share Amount
  4. 4
    Calculate crew pool
    Net Stock − Vessel Share Amount = Crew Pool
  5. 5
    Sum all share units
    Total Share Units = sum of all crew share units
  6. 6
    Calculate value per share unit
    Crew Pool ÷ Total Share Units = Value Per Unit
  7. 7
    Calculate each crew member's gross pay
    Value Per Unit × Individual Share Units = Gross Pay
  8. 8
    Apply advances and deductions
    Gross Pay − Advances − Other Deductions = Net Settlement

Owner-operator: when the captain also fishes

Many commercial fishing captains own their vessel and also work as active crew. In this case, the captain receives two forms of compensation from the same trip:

The vessel share goes to the vessel (which the captain owns). The captain also participates in the crew pool as an active crew member, receiving share units like any other deckhand - typically 1.0 to 1.5 units depending on the vessel agreement.

This is not double-dipping. The vessel share compensates the asset. The crew share compensates the labor. They are different things and should be documented separately on the settlement sheet.

If you own the vessel and fish on it, your settlement sheet should show your crew share payout separately from your vessel share income. Your CPA needs them categorized differently at tax time - crew share goes on Schedule C as self-employment income; vessel share income flows through your business entity.

What goes on a settlement sheet

A crew settlement sheet is a legal document. It is how a crew member proves their income to the IRS, to a bank when applying for a loan, and in any pay dispute. Every settlement sheet should include:

  • Vessel name and USCG documentation number
  • Trip start and end dates
  • Processor name and fish ticket number(s)
  • Gross stock amount with species breakdown
  • Itemized shared expense deductions
  • Vessel share percentage and dollar amount
  • Crew pool total
  • Each crew member's name, share units, and gross pay
  • Any advances or deductions with explanations
  • Net settlement amount per crew member
  • Employment classification (1099 or W-2)
  • Signature line for each crew member
  • Captain's signature

1099 vs. W-2: which applies to your crew?

Most commercial fishing crew members are classified as 1099 independent contractors. However, the classification depends on the specifics of the working arrangement - not on what you prefer or what's easier.

1099 Independent Contractor
  • • Crew member paid a share of the catch
  • • No guaranteed minimum pay
  • • Crew member controls their own work methods
  • • No employer payroll tax withholding
  • • Captain issues Form 1099-NEC at year end
  • • Most common in salmon, crab, halibut, shrimp
W-2 Employee
  • • Crew member paid hourly or flat rate
  • • Employer withholds federal and state income tax
  • • Employer pays 7.65% FICA match
  • • Captain issues W-2 at year end
  • • More common on processing vessels and some union boats
The IRS audits fishing operators on this question. Getting it wrong means back payroll taxes plus penalties. The classification must be decided before the trip - not at tax time. Document it on the settlement sheet.

Common mistakes captains make

Mistake 1: Calculating crew share on the wrong gross stock

The shared expense deductions must come out before the vessel/crew split - not after. Splitting first, then deducting expenses from the crew's share is mathematically wrong and will overpay or underpay crew members.

Mistake 2: Verbal shared expense agreements

If fuel is a shared expense, that has to be in writing before the trip. The IRS and any crew dispute arbitration will ignore verbal agreements.

Mistake 3: Not tracking processor advances

A $30,000 advance from a Bristol Bay processor comes off the crew settlement at season end. If you don't track it in writing with the crew member's acknowledgment, you cannot legally deduct it.

Mistake 4: Treating all crew as 1099 by default

1099 is correct for most share-based crew, but not all. Flat-rate crew on some vessels may qualify as W-2 employees. The IRS knows the difference.

Mistake 5: No signed settlement sheets

An unsigned settlement sheet is better than nothing. A signed one is the only thing that protects you when a crew member claims they were paid less than they're owed.
