aquaculture husbandry technician
Role lens
Are you fascinated by aquatic life and enjoy hands-on work? As an aquaculture husbandry technician, you'll play a vital role in the sustainable production of fish, shellfish, and other aquatic organisms, ensuring their health and optimal growth.
Aquaculture husbandry technicians are specialists in the practical aspects of aquatic organism production. Your days are spent directly involved in the care and management of growing populations, focusing on feeding schedules, monitoring health, and maintaining optimal environmental conditions. This role requires a blend of scientific understanding and practical skills, ensuring efficient and responsible aquaculture practices.
- • Monitoring and adjusting water quality parameters (temperature, salinity, oxygen levels) to ensure optimal conditions for aquatic life.
- • Preparing and distributing feed according to specific nutritional requirements and growth stages.
- • Observing and recording the health and behaviour of aquatic organisms, identifying and reporting any signs of disease or stress.
