water-based aquaculture technician
Role lens
Are you fascinated by marine life and enjoy working outdoors? As a water-based aquaculture technician, you’ll play a vital role in sustainably raising aquatic organisms, contributing to the growing demand for seafood while ensuring healthy ecosystems.
Water-based aquaculture technicians are skilled professionals who coordinate and oversee the cultivation of aquatic organisms in suspended systems, such as floating cages, submerged structures, or longlines. This role combines practical hands-on work with supervisory responsibilities, ensuring the health and well-being of the organisms and the efficient operation of the aquaculture facility. It’s a career that blends technical expertise with a commitment to responsible aquaculture practices.
- • Supervise the daily activities related to fattening aquaculture organisms in floating or submerged systems.
- • Participate in the careful extraction and handling of organisms prepared for commercial sale.
- • Oversee the maintenance and repair of essential equipment and facilities, including cages, rafts, and longlines.
