Description

Aquaculture recirculation managers control the production of aquatic organisms in land-based recirculation systems, manage water re-use processes and supervise complex circulation, aeration and biofilter systems.

Duties

Here are some typical duties of aquaculture recirculation managers:

  • Collaborate with engineers and aquaculture experts to design and implement recirculating aquaculture systems tailored to the specific needs of the target species.
  • Monitor and manage water quality parameters such as oxygen levels, pH, ammonia, nitrite, and temperature to maintain optimal conditions for aquatic species.
  • Develop and implement feeding strategies to ensure that fish or shrimp receive the appropriate nutrition while minimizing waste and environmental impact.
  • Monitor the health of aquatic organisms, detect diseases, and implement preventive measures or treatments when necessary.
  • Establish and enforce biosecurity protocols to prevent the introduction of pathogens and diseases into the aquaculture system.
  • Oversee regular maintenance tasks, including cleaning filters, checking pumps, and conducting routine system inspections to ensure efficient operation.
  • Collect and analyze data on system performance, growth rates, and water quality, using the information to optimize production and troubleshoot issues.
  • Implement sustainable practices, such as water reuse, energy-efficient technologies, and waste management, to minimize the environmental impact of aquaculture operations.
  • Train and supervise aquaculture staff, ensuring that team members are proficient in system operation, maintenance, and emergency response.
  • Stay informed about and ensure compliance with local, state, and federal regulations governing aquaculture practices.

Working conditions

Aquaculture recirculation managers work in indoor or greenhouse facilities, managing RAS for fish or shrimp production. The role may involve irregular hours, especially during critical production stages. Managers may work closely with a team of aquaculture technicians, engineers, and biologists.

Minimum qualifications

Bachelor’s degree is generally required to work as aquaculture recirculation manager. However, this requirement may differ in some countries.

To become an aquaculture recirculation manager, a bachelor’s or master’s degree in aquaculture, fisheries management, marine biology, or a related field is typically required. Practical experience in aquaculture operations, especially with recirculating systems, is valuable. Continuous learning and staying updated on advancements in aquaculture technology, water quality management, and environmental sustainability contribute to success in this role. Strong managerial, problem-solving, and communication skills are essential for overseeing a complex aquaculture system.

ISCO skill level

ISCO skill level is defined as a function of the complexity and range of tasks and duties to be performed in an occupation. It is measured on a scale from 1 to 4, with 1 the lowest level and 4 the highest, by considering:

  • the nature of the work performed in an occupation in relation to the characteristic tasks and duties
  • the level of formal education required for competent performance of the tasks and duties involved and
  • the amount of informal on-the-job training and/or previous experience in a related occupation required for competent performance of these tasks and duties.

Aquaculture recirculation manager is a Skill level 4 occupation.
