  • Assist with experiments relating to nutrition or methods of controlling predators, parasites and other disease-causing organisms.
  • Monitor the environment using oxygen meters, salinity meters, pH (acidity) meters and water chemistry analysis kits.
  • Maintain live feed and algae cultures.
  • Keep records of breeding, production and treatment programs.
  • Develop and implement systems of profitable farm management.
