To start a salmon fish farm, first define the species, production system, scale and intended market; then test whether a specific site is environmentally suitable, legally available and financially workable before committing major capital. There is no universal permit list, startup budget or proven profitability figure: each depends on the country, location and farm design.
What kind of salmon farm do you plan to build?
“Salmon farm” can describe different production stages and systems. FAO’s Atlantic salmon profile describes a pathway that includes hatchery and smolt stages before grow-out. A business may handle multiple stages or depend on other operators for some of them; decide what your project will actually do before comparing sites or estimating costs.
Write down the decisions that shape the project:
- Purpose and scale: Is this a pilot or a commercial operation, and what output do you intend to pursue?
- Species and market: Which salmon species will you raise, and who is the intended buyer?
- Production system: Are you considering marine cages or a land-based system?
- Production stages: Will you operate a hatchery, raise smolts, grow fish to market size, or rely on suppliers and partners for some stages?
These are feasibility choices, not details to postpone until construction. They affect the site requirements, approvals, staffing, input supply and capital plan. FAO’s site-selection guidance emphasizes defining the production objective and system before selecting a site.
How should you screen a site?
Screen candidate locations before buying land, commissioning construction or ordering equipment. FAO’s site-selection guidance treats site choice as both a technical and a non-technical decision: water and climate matter, but so do law, infrastructure, social conditions, markets and access to production inputs.

For a marine-cage concept, assess the factors below with qualified aquaculture and engineering advice. The coho salmon profile identifies these as site considerations, but its species-specific figures and practices should not be treated as design standards for Atlantic salmon or other salmon farms.
| Assessment area | Questions to answer | Why it matters to feasibility |
|---|---|---|
| Water and site conditions | What are the temperature, dissolved oxygen, salinity, depth and current conditions? How exposed is the site to storms, and how does it relate to other farms? | These conditions inform whether the proposed system and production plan merit further design and assessment. |
| Infrastructure and access | Can the site be reached and supported by the infrastructure, transport and services the project needs? | Access and infrastructure affect implementation and operating plans; price them for the specific location rather than assuming they are available. |
| Inputs and workforce | Can the project obtain stock, feed, equipment, materials and labor on workable terms? | Availability and cost belong in the business case, not just the construction estimate. |
| Markets and logistics | Can the farm reach intended buyers and move its output through the required transport chain? | A technically suitable site is not automatically a viable business location. |
| Legal and social setting | What land, water, environmental, planning and aquaculture constraints may apply? How could the proposal affect or be affected by local communities and uses? | These factors can shape whether a project can proceed and on what conditions. |
For land-based proposals, investigate system-specific water supply and discharge needs, energy requirements, construction and operating costs, and regulatory obligations. The available FAO material does not establish a current numerical cost comparison between land-based systems and marine cages, so compare project quotations and requirements rather than assuming one system is cheaper.
How do you assess water quality and carrying capacity?
Water assessment is both a site-selection task and an operating responsibility. FAO guidance recommends sampling and laboratory assessment of physical, chemical, biological and microbiological properties; listed measures include dissolved oxygen, pH, salinity and ammonia. Use qualified specialists to determine the sampling plan and how results apply to the proposed species, system and location.

Before investment, establish what will be measured, how often it will be checked during operations, who will review results and what action follows an out-of-range result. FAO environmental-management guidance calls for ongoing monitoring of stock, water quality and hygiene; a one-time test cannot stand in for that operating plan.

FAO proceedings distinguish physical, production, ecological and social carrying capacity. For a salmon proposal, examine nutrient wastes and benthic effects, escape risk, and interactions with wild ecosystems. A stocking level used at another farm is not a universal capacity limit; site-specific analysis is needed.
What health and biosecurity plan should be in place?
Build fish-health services and disease prevention into the project design. The operating plan should cover surveillance, monitoring, diagnostic support and response, rather than treating health management as an expense to add after stocking. FAO’s 2023 Progressive Management Pathway for Aquaculture Biosecurity describes a risk-based approach that spans enterprise, national and regional levels.
Specify who is responsible for health decisions, what monitoring and diagnostic arrangements are available, how concerns are escalated and what resources are needed to respond. The exact controls must be designed for the farm, local rules and risks; a general checklist cannot substitute for veterinary and regulatory advice.
How do you build a realistic financial plan?
Do not start with a headline startup-cost estimate. First define the farm’s location, species, production stages, system, scale, engineering needs, energy and labor requirements, input sources, approvals and intended buyers. Then ask qualified professionals and suppliers for location- and design-specific estimates. The FAO sources available here do not provide a defensible universal startup budget or profitability estimate.
Build a project budget that separates one-time development from recurring operations. Tailor the line items to the proposed farm; likely areas to price include:
Rank #4
- Development and capital: site investigation, design and engineering, land or site access, construction, equipment, and any system-specific water or energy infrastructure.
- Approvals and compliance: application preparation, required studies, monitoring and any ongoing operating conditions identified by authorities.
- Operating inputs: stock and feed, labor, energy, materials, equipment upkeep, transport, water-quality monitoring and fish-health services.
- Sales and delivery: costs and logistics associated with reaching the intended buyers.
Record the basis for every estimate—supplier quote, engineering estimate, authority requirement or internal assumption—and distinguish one-time costs from recurring costs. Model more than one case for uncertain inputs such as timing, input prices and buyer terms. Do not treat projected sales as assured income or omit the resources needed to reach the planned production stage.
Before deciding to proceed, check whether available financing can cover the development period as well as operating needs, and whether the plan remains viable if approvals, construction or market access take longer or cost more than expected. This is a project-specific financial test, not a claim that salmon farming guarantees a return.

The exact permit applications, agencies, studies and operating conditions depend on the jurisdiction and proposed site. Relevant issues may include aquaculture or fisheries authorization, environmental assessment, water-use rights, fish-health rules and construction approval, but this is not a universal checklist. FAO legislation guidance describes permits as a way to assess environmental sustainability and says site suitability should be reviewed before a permit is issued.

Identify the current requirements directly with the local aquaculture, fisheries, environmental and planning authorities. Ask which approvals must be obtained before site work, construction, water use, stocking and operation, and what information each application requires. Confirm the sequence in writing with the relevant authorities and qualified local advisers before making commitments that depend on approval.
What is a sensible order for starting?
- Write the concept: define species, scale, production stages, marine-cage or land-based system, and target market.
- Screen locations: compare water and site conditions with infrastructure, transport, markets, inputs, legal constraints and social factors.
- Commission site and water assessment: obtain qualified sampling and analysis, and assess ecological and social capacity for the proposed operation.
- Develop the operating design: plan health services, biosecurity, monitoring, stock and feed supply, staffing and logistics.
- Confirm the approval pathway: consult the relevant local authorities about studies, applications, sequencing and conditions before committing major capital.
- Complete the financial case: use location-specific engineering, supplier and compliance estimates, then test whether financing and market assumptions support proceeding.
Site selection is foundational, not a box to tick after choosing equipment. As J. Kövári puts it in FAO’s Considerations in the Selection of Sites for Aquaculture, “The success of an aquaculture project depends to a large extent on the proper selection of the site to be developed into a fish farm or hatchery.”
