Course Title: Life Support System Design and Operation
Credit Hours: 4
Lecture Hours: 30
Lecture/Lab Hours: 20
Lab Hours: 0
Special Fee: none
Examines the role of life support systems in maintaining a balanced, stable aquatic environment. Presents how to design, construct, maintain and troubleshoot semiclosed, closed and open systems. Prerequisite: AQS 215 (this is more of a co-requisite since the two courses occur simultaneously).
Intended Outcomes for the Course
- Identify water quality parameters impacted by life support systems and relate the use of associated equipment to evaluate aquatic environments.
- Identify the functions and the relationships of life support system components in maintaining a balanced aquatic system.
- Size and select appropriate life support system components and equipment for an aquatic system.
- Troubleshoot and remedy faulty life support system components.
- Diagram the flow of water from its source to its discharge location.
- Design and build an aquatic life support system.
Course Activities and Design
The format for this course is a combination of lecture, demonstration, and laboratory experience to provide necessary skills in how to properly design and operate life support systems for aquariums and their inhabitants. Laboratory instruction will be based at the OCCC Central Campus Aquarium Science building.
Outcome Assessment Strategies
- Laboratory activities and skill development sessions that utilize tools, materials and equipment for the construction and operation of life support systems.
- Construction and installation of a physical life support system.
- Term project utilizing information resources for the planning and design of a theoretical life support system for an exhibit, aquaculture or research application.
- Scheduled quizzes and examinations to evaluate knowledge of tools, materials, equipment, filtration components, water monitoring devices, and their associated selection, function and safe use within life support systems.
- Final comprehensive exam includes national certification with the Aquatic Animal Life Support Operators Level One Operator certification.
