In words

The site manager is responsible for several hundred thousand living animals in an open sea, from smolt input to harvest, and for everything that determines whether they thrive: feeding, growth rates, oxygen, temperature, net integrity, sea lice, predators, mortality, and welfare. The measure of the job is a biological one — did the fish grow well, healthily, and survive — expressed in production numbers the manager is accountable for weekly.

The distinct contribution is growth held at scale, in a medium nobody controls. A farmer whose crop fails can see the field. This stock is underwater, read through feed response, cameras, probes and mortality counts, so the state of a population that can barely be observed has to be inferred. Site managers describe developing something like a sense for a pen — knowing the fish are off before the data says so.

The technology arrived faster than the reputation. A modern marine site is sensors, cameras, automated feed systems, environmental monitoring and software that recommends decisions the manager can override. The manager's role has shifted toward interpreting a data stream and knowing when the model is wrong, which is a genuinely skilled judgement job wearing waterproofs.

There's a guide here if you want one

Kitsune can talk through anything on this page — whether it might suit you, what to do next, questions this page doesn't answer. Everything here is yours to read either way.

A bad event is emotionally heavy in a way nobody warns about in advance. Mass mortality — a bloom, a disease outbreak, a jellyfish incursion — means arriving to find a great many dead animals that were somebody's responsibility, cleaning it up over days, and reporting it. People in this industry are frank that these events stay with a person, and that treating welfare as real rather than as a compliance line is what makes them bearable.

The industry is publicly contested, and the job comes with personal implication in that. Sea lice, escapes, wild salmon interactions, and welfare are live arguments, and the role includes being the person locals ask about at the shop. The defensible position is competence — the sector's own critics are frequently correct about the past — and it has to be held honestly rather than by denying the history or drowning in it.

And the pay is genuinely good, which is the part that never reaches careers guidance. Scottish salmon farming reports average earnings around £44,500, roughly 16% above the national average, with year-round roles in places where year-round work is scarce [reported by people in the field, Salmon Scotland 2025]. Site managers in Scotland sit around £32,000–£38,000 and up, reaching about £55,000 senior [from salary and job-posting data, Prospects / Planit 2025]. For a career that opens at eighteen without a degree, that is close to unmatched on this map.

The open door is real: farm hand or apprentice at eighteen, then husbandry technician, senior technician, assistant manager, manager — a route the industry actively recruits into at every level [reported by people in the field, Salmon Scotland 2025]. Starting salaries around £18,000–£22,000 rising to £30,000–£35,000 with a few years [from salary and job-posting data, Prospects 2025]. A degree in aquaculture, marine biology or fish health speeds the technical and management climb rather than gating it. Boat handling, sea survival and health-and-safety certification are practical necessities. In Portugal the equivalent academic route is a licenciatura or mestrado in Aquacultura e Pescas, with IPMA internships as the standard practical entry [IPMA / university admissions 2025].
