Fish Farm Technician


At this level of job, you will lead a small team in daily operations on site, usually working under the direction of the Assistant Site Manager or Site Manager. The focus will be on successful fish production, including feeding, grading, harvesting, net changing and other general farm maintenance tasks, including boat handling.

Freshwater fish are kept in tanks, ponds, cages, or concrete raceways. Sea fish are usually housed in sea cages or large pens. Shellfish are farmed in their natural marine environment; for example, mussels are reared on ropes hanging in the sea.

In salmon farming, the fish are bred in fresh water for six months to two years, and then transferred to pens in the sea until they are mature and ready to sell.

Working Conditions

Fish farms operate seven days a week, so farmers usually work flexible hours based around the jobs that need completing at different times of the year. In larger farms, they are likely to work on a rota system with other members of staff. This will include early mornings, evenings and weekends. There may be opportunities for both full-time and part-time working.

You need to be comfortable working over water and willing to do flexible hours to meet the demands of the job. This may include overtime and weekend cover, usually in a rota.

Most working time is spent outdoors in all weathers. Many fish farms are in relatively remote sites, but housing is often provided with the job. The work itself is active and involves a lot of heavy lifting, standing, bending and carrying.

Fish farmers may need to collect feed or equipment and make deliveries of fish, so a driving licence is needed.
