About water-based aquaculture technician

As a water-based aquaculture technician in Poland, you will coordinate and supervise daily aquaculture operations in suspended systems such as floating cages, submerged structures, rafts, longlines, and bouchot installations. Your role is crucial to maintaining healthy fish and shellfish populations while ensuring efficient production. You will monitor water quality, observe fish behavior for signs of disease, manage feeding operations, and supervise the maintenance of all equipment and facilities used in the farming system.

Your day-to-day work involves continuous observation and assessment of the aquaculture environment, with responsibilities spanning from routine feeding and growth monitoring to emergency disease response and facility maintenance. You will use computerized feeding systems and aquaculture production planning software to optimize operations and maintain detailed records. The aquaculture industry in Poland is growing, particularly in sea bass, sea bream, and shellfish farming. This role demands strong observational skills, knowledge of animal welfare and fish health, comfort working in marine environments, and the ability to operate small boats and heavy equipment.
