Reviews the common infectious and noninfectious diseases of captive fish and invertebrates. Examines the common techniques of fish and invertebrate health management. Prerequisite: AQS 215 or consent of instructor.
Intended Outcomes for the Course
- Identify the common signs of disease in fish and invertebrates.
- Describe the common infectious and noninfectious diseases associated with captive aquarium fish.
- Demonstrate proper use and maintenance of laboratory instrumentation.
- Demonstrate proper necropsy and sample collection techniques.
- Formulate a health management and biosecurity plan based upon the results of diagnostic testing, water quality measurements and professional consultation.
- Perform common treatment methodologies.
Course Activities and Design
The format of this course is a combination of lecture, demonstration, case-based activities, written assignments and laboratory experience to provide the necessary skills to develop disease prevention strategies, identify disease and develop treatment/management plans for aquarium systems and their inhabitants.
Outcome Assessment Strategies
- Laboratory activities and skill development sessions that utilize tools, materials and equipment for prevention and identification of common health problems associated with aquarium fish.
- Term project utilizing information and resources to develop a biosecurity plan for a selected animal holding facility.
- Case–based activities that utilize skills and knowledge to identify health and animal holding system problems and develop treatment and management strategies.
- Scheduled quizzes and examinations to evaluate knowledge of tools, materials, equipment, procedures and problem solving associated with common fish and invertebrate health problems encountered in the captive setting.
- Writing assignments that utilize the knowledge and skills of fish and invertebrate health management to communicate common diseases, management and husbandry practices to professional colleagues.
