Credit Hours: 4
Lecture Hours: 30
Lecture/Lab Hours: 20

Special Fee: none
Reviews the life history and captive care requirements of invertebrates commonly cultured in the aquatic animal industry/profession. Prerequisite: AQS 100 or consent of instructor.
Intended Outcomes for the Course
- Recognize and identify internal and external features of commonly kept and cultured aquatic invertebrates.
- Discuss the important physiologic characteristics of aquatic invertebrates including reproduction, locomotion, and osmoregulation.
- Describe the natural life history of commonly kept and cultured aquatic invertebrates.
- Identify the husbandry requirements for selected aquatic invertebrates.
- Design a culture system suitable for selected aquatic invertebrates.
Course Activities and Design
The course consists of lectures, laboratory exercises, student presentations, group discussion, reading, writing assignments, independent research, and field trips. Laboratory instruction will be based at the OCCC central campus Aquarium Science building.
Outcome Assessment Strategies
- Laboratory exercises with introduction to diversity, species identification, internal and external anatomy, specimen handling, specimen collection, and behavioral observations.
- Scheduled exams to evaluate knowledge of material presented in lecture, labs, and assigned reading.
- Discussion and synthesis of primary scientific literature relevant to the biology of captive invertebrates.
- Development, completion, and oral presentation of individual research projects on the culture and/or care of captive invertebrates.
