Aquaculture rearing technician jobs in Finland
Aquaculture rearing technicians operate in aquatic organisms' production. They are specialists in the rearing, weaning and production of juveniles.
Aquaculture rearing technician - Which skills are essential?
Monitor fish mortalities and assess possible causes.
Operate equipment for water disinfection, using different methods and techniques, such as mechanical filtration, depending on needs.
Maintain the production of juveniles at the nursery stage using advanced high density production techniques
Ensure that operations comply with standards for sustainable aquaculture.
Monitor the health of fish, based on feeding and general behaviour. Interpret environmental parameters and analyse mortalities.
Measure flow of water in tanks and natural freshwater bodies. Measure parameters of water quality, such as pH, temperature, oxygen, salinity, CO2, N2, NO2, NH4, turbidity, and chlorophyll.
The processes which allow the identification and classification of fish.
Induce spawning using appropriate techniques for specific cultured species of fish, molluscs, crustaceans or others. Determine sexual maturity of broodstock, using appropriate techniques as indicated for cultured species of fish, molluscs and crustaceans. Control broodstock sexual cycle. Use hormones to induce reproduction.

Assess the impact of biological conditions such as algae and fouling organisms by managing water intakes, catchments and oxygen use.
Monitor feeding behaviour in order to decide on suitability of feed composition, weaning larvae from live prey to dry feed or pellets.
Operate water heating and pump equipment as appropriate such as electrical heaters, heat exchangers, heat pumps, and solar pumps.
Collect naturally spawned fish eggs, eliminate egg adhesiveness, incubate eggs until hatching, hatch and maintain newly born larvae, monitor larvae status, carry out early feeding and rearing techniques of the cultured species.
Measure water quality: temperature, oxygen, salinity, pH, N2, NO2,NH4, CO2, turbidity, chlorophyll. Monitor microbiological water quality.
Make minor repairs to hatchery facilities as required.
Operate different water oxygenation systems according to requirements: surface aerators, paddle wheel aerators, column/cascade aerators, and pure oxygenation systems.
Carefully maintain hatchery production records and inventory. Maintain accurate hatchery records including the preparation of health documents for the transport of juveniles.
Feed broodstock according to nutritional needs. This will initially include live prey such as rotifers and artemia.
Identify the symptoms of fish diseases. Apply appropriate measures to treat or eliminate diagnosed conditions.
Monitor and maintain hatchery production, monitoring stocks and movements.
Make sure that health and safety procedures have been established and followed across all aquaculture facilities including cages. Ensure that personnel and general public are instructed and all work activities are carried out according to relevant health and safety regulations.
The methods, characteristics and equipment used to cultivate phytoplankton, microalgae and live prey such as rotifers or Artemia with advanced techniques.
Be aware of the general principles of the concept of bio-security and in particular, the disease prevention rules to be implemented in case of epidemics endangering public health.
Use appropriate implements to collect shellfish spat. Sort wild shellfish spat. Collect naturally spawned fish eggs; eliminate egg adhesiveness and incubate eggs until hatched. Handle fish and shellfish broodstock and feed according to their needs.
