  • Assessment of risks and threats

    The security documentation and any security-related communications and information.

Skills

  • Maintain recirculation systems

    Monitor and maintain water circulation within holding units. Monitor the condition of the water filtering and purification equipment.

  • Preserve fish samples for diagnosis

    Collect and preserve larval, fish and mollusc samples or lesions for diagnosis by fish disease specialists.

  • Carry out fish disease prevention measures

    Carry out disease prevention measures for fish, molluscs, and crustaceans for land-based and water-based aquaculture facilities.

  • Monitor water quality

    Measure water quality: temperature, oxygen, salinity, pH, N2, NO2,NH4, CO2, turbidity, chlorophyll. Monitor microbiological water quality.

  • Apply fish treatments

    Apply prescribed fish treatments under supervision, including assistance with vaccination immersion and injection procedures.

  • Interpret scientific data to assess water quality

    Interpret biological and physico-chemical data to assess water quality.

  • Monitor fish mortality rates

    Monitor fish mortalities and assess possible causes.

  • Monitor feeding behaviour

    Monitor feeding behaviour of farm animals. Collect information on the growth of the animals, and forecast future growth. Monitor and assess biomass taking mortality into account.

  • Draw up risk assessment

    Assess risks, propose improvements and describe measures to be taken at the organisational level.
