Aquarist
Maintain the health of aquatic life and manage the ecosystems within captive water environments.
Overview
The daily reality of an aquarist involves a blend of rigorous physical labor and scientific monitoring. Mornings often begin with water quality testing and system inspections to ensure filtration and temperature controls are functioning within precise parameters. The work is rhythmic and dictated by the biological needs of the animals, requiring constant observation to detect subtle changes in health or behavior that could indicate environmental stress or illness.
Problem-solving in this field frequently revolves around engineering challenges and biological puzzles, such as repairing a specialized pump or diagnosing a nutritional deficiency in a rare species. Professionals who excel in this career typically possess high attention to detail and a calm demeanor under pressure. While the environment is often damp and physically demanding, it offers the stability of routine coupled with the intellectual satisfaction of maintaining fragile ecological balances.
Responsibilities
- Monitor and adjust water chemistry parameters including pH, salinity, and dissolved oxygen levels.
- Prepare specialized diets and execute feeding schedules for a diverse range of aquatic species.
- Perform routine maintenance on life support systems such as protein skimmers and mechanical filters.
- Administer medical treatments and assist veterinarians with clinical procedures for ill or injured animals.
- Design and maintain naturalistic exhibits that meet the physiological and behavioral needs of inhabitants.
- Maintain detailed records of animal behavior, health status, and environmental data for institutional databases.
- Participate in public educational presentations to share information about marine biology and conservation.
Qualifications
- A bachelor degree in marine biology, zoology, or a closely related biological science field.
- Professional SCUBA certification from an internationally recognized agency like PADI or NAUI.
- Demonstrated knowledge of aquatic animal husbandry and life support system operations.
- Physical ability to lift heavy equipment and perform tasks in aquatic environments.
- Strong observational skills for monitoring animal health and behavior patterns.
Nice to have
- Advanced certifications in specialized water chemistry analysis or life support system engineering.
- Experience in breeding and larval rearing of rare or endangered aquatic species.
- Previous experience working in an AZA-accredited facility or research institution.
Work environment
