What it costs, what it earns, and how to stage the risk.
Take a barn. Fill it with heated saltwater pools. Stock them with post-larvae shipped from Florida. Fourteen weeks later, harvest fresh shrimp that Ontario restaurants pay a premium for.
The best public data comes from Purdue University's study of operating Indiana farms using 8-pool biofloc systems [1]. Indiana and Ontario share the same core challenge - both need heated indoor facilities year-round - so the model translates, with adjustments for Ontario's higher costs.
Each pool takes 7,200 post-larvae. At 70% survival and a 1.4:1 feed conversion ratio, you harvest at 20g ("21/25" count) - the most profitable size. Staggered bi-weekly harvests keep a steady supply [1].
Full 8-pool system: ~$85,500 USD / ~$113,000 CAD [1]. Well under $200K.
The pools are the biggest line item at $6,500 each, sold as complete units with pumps, aeration, and biofloc settling. Add a water heater ($4,700), emergency generator ($4,500 - power loss kills the entire stock), water quality testing ($6,624), and water storage ($2,600). Building renovation for an existing barn: $5,000 [1].
The biggest annual expense is the baby shrimp themselves. 201,600 post-larvae at $0.10 each = $20,160, a quarter of total operating costs [1].
Ontario adjustment: Purdue used 2015 Indiana wages ($10/hr) and energy ($0.06/kWh). Ontario minimum wage is $17.20/hr, electricity ~$0.13/kWh with longer heating seasons, and post-larvae must be imported from the US. Total annual operating costs rise from ~$85,600 USD to roughly $115,000-120,000 CAD.
| Expense | Indiana (USD) | Ontario est. (CAD) | Share |
|---|---|---|---|
| Post-larvae | $20,160 | ~$28,000 | 24% |
| Labor (3 hrs/day) | $10,950 | ~$25,000 | 21% |
| Feed (7,904 lbs) | $9,485 | ~$13,000 | 11% |
| Loan repayment | $7,795 | ~$10,000 | 9% |
| Depreciation | $6,684 | ~$9,000 | 8% |
| Heating | $4,485 | ~$8,000 | 7% |
| All other | $5,745 | ~$7,000 | 6% |
| Total annual | ~$85,600 | ~$117,000 |
Your production cost is roughly $19-20 CAD/lb. The question is what buyers already pay.
Frozen imported shrimp at Canada's largest grocer runs $11-25 CAD/lb depending on species and size [2]:

| PC Pacific White (400g) | $10.00 | $11.34 |
| Seaquest Pacific White (300g) | $8.99 | $13.60 |
| Wild Atlantic Cold Water (340g) | $13.99 | $18.66 |
| PC Organic Black Tiger (300g) | $15.49 | $23.42 |

A Toronto seafood supplier selling to consumers and restaurants. Their retail prices for frozen imported shrimp by count [10]:
| Product | Size | Price | CAD/lb |
|---|---|---|---|
| White PDTO 21/25 (same count as our target) | 2 lb | $35.00 | $17.50 |
| White PDTO 16/20 | 2 lb | $40.00 | $20.00 |
| White PDTO 8/12 | 2 lb | $50.00 | $25.00 |
| Black Tiger Easy Peel 6/8 | 2 lb | $53.00 | $26.50 |
| Wild Argentina 16/20 | 2 lb | $45.00 | $22.50 |
Their bulk pricing for restaurants and foodservice [11]:
| Product | Case | Price | CAD/lb |
|---|---|---|---|
| White PDTO 21/25 | 10 lb | $145.00 | $14.50 |
| White PDTO 16/20 | 10 lb | $165.00 | $16.50 |
| White PDTO 13/15 | 10 lb | $185.00 | $18.50 |
| White PDTO 8/12 | 10 lb | $195.00 | $19.50 |
| Black Tiger PDTO 8/12 | 10 lb | $250.00 | $25.00 |
The pricing picture is better than expected. Frozen imported 21/25 count wholesales at $14.50/lb and retails at $17.50/lb. Your Ontario production cost is $19-20/lb. You can't compete on price with frozen imports - but the gap is small. Fresh, never-frozen, locally-farmed shrimp at $25-30/lb is a modest step up from what consumers already pay at the premium end, not an absurd markup. Planet Shrimp already sells through Gordon FoodService at premium prices [3].
| Channel | Price (CAD/lb) | Revenue (8 pools) | Profit | Margin |
|---|---|---|---|---|
| Wholesale (competing with frozen) | $14-17 | $87K-106K | Loss | - |
| Restaurant / foodservice | $20-25 | $124K-156K | $4K-36K | 3-23% |
| Direct-to-consumer | $25-30 | $156K-187K | $36K-67K | 23-36% |
| Mixed (50/50 restaurant + DTC) | ~$24 avg | $149K | $29K | 19% |
Undercutting frozen import wholesale doesn't work. But restaurant and direct-to-consumer channels are viable - you're selling freshness and provenance, not competing on price.
The single variable that determines profitability: how many shrimp survive to harvest. The Purdue sensitivity analysis [1]:
| Survival | $14/lb | $16/lb | $18/lb |
|---|---|---|---|
| 80% | 14% | 30% | 46% |
| 70% | 2% | 16% | 31% |
| 60% | -13% | 2% | 15% |
| 50% | -28% | -15% | -3% |
At 50% survival, you lose money at every price. At 70%, you need $16+/lb. The gap between a 60% and 80% farmer at the same price is the gap between breaking even and a 30% margin. You need to learn to keep shrimp alive before investing in selling them.
The system is modular. About $25,000 USD is shared infrastructure - building, heater, generator, water quality equipment, storage, plumbing. It serves the whole facility whether you run 1 pool or 8 [1] [9]. Each additional pool costs ~$7,150 USD [1].
Fewer pools means the same fixed costs spread over less production. It also means less space - which opens up urban locations.
Each 4,200-gallon pool is roughly 17ft in diameter at 3ft water depth. With walkways and clearance, a pool needs about 400 sq ft of floor space. Add shared space for equipment, water storage, and a small processing/purge area (~300-500 sq ft), and the total footprint is:
| Pools | Pool area | Shared area | Total sqft | CAPEX (CAD) | Yield (lbs/yr) | Breakeven |
|---|---|---|---|---|---|---|
| 1 | ~400 | ~300 | ~700 | ~$44K | ~780 | $45-51/lb |
| 3 | ~1,200 | ~400 | ~1,600 | ~$64K | ~2,330 | $24-28/lb |
| 5 | ~2,000 | ~400 | ~2,400 | ~$83K | ~3,890 | $21-23/lb |
| 8 | ~3,200 | ~500 | ~3,700 | ~$113K | ~6,220 | $19-20/lb |
Urban production is realistic. A 3-pool pilot fits in 1,600 sq ft - the size of a large garage, a small warehouse bay, or a basement commercial unit. Even 8 pools only needs 3,700 sq ft. The building needs to be insulated, ventilated, have a concrete floor and adequate drainage, and hold 27C water temperature year-round [7]. Industrial condos, food-grade commissary spaces, and converted retail could all work.
One pool is tuition, not a business. Breakeven at $45-51/lb. You'll lose $15-20K/year. Only worth it if you're paying to learn before committing real capital.
Three pools is the minimum viable pilot. Breakeven at $24-28/lb - achievable through direct sales. Near breakeven while you prove two things: you can keep 70%+ alive, and customers will pay $25+/lb. Multiple pools also let you stagger harvests for steady supply.
Build shared infrastructure once, sized for 8. Add pools as you earn the right to scale.
Run 2-3 crop cycles. Goal: 70%+ survival and a customer list. Accept near-breakeven as the cost of learning.
Survival is consistent, buyers are repeating. Add 2 pools. Same infrastructure, more volume. Should cross into profitability.
Biology and market proven. Full 8-pool system. 15-30% margins at $20+ CAD/lb. Total invested: ~$106K CAD.
You risk $64K before knowing if you can grow and sell shrimp. The remaining $42K deploys only after real validation.
Atarraya sells the Shrimpbox - a shipping container converted into a self-contained shrimp farm. $50,000 USD per unit, claims up to 3,307 lbs/year, with AI-monitored biofloc and automated feeding [5] [6].
Tradeoffs: plug-and-play simplicity, but 8% royalty on every kilogram sold plus feed/larvae at market price. The 20% ROI claim is unverified. Canadian availability unclear. Unit economics are similar to the DIY approach, but you trade margin for convenience.
Feasible under $200K. Modular, proven technology. Real market for premium local shrimp - consumers already pay $11-25 CAD/lb for frozen imports at Loblaws, and $17-27/lb at specialty retailers like Daily Seafood. The premium gap for fresh local is smaller than it looks.
At 8 pools, 70% survival, and mixed restaurant/direct sales: ~$29K CAD annual profit on ~$117K operating costs. A 19% margin. Supplemental income, not a livelihood.
The risk is biological, not financial. Everything depends on keeping 70% of your shrimp alive for 14 weeks in a system where one equipment failure kills the stock. Start with 3 pools at $64K. Prove it works. Then scale.
