AGS 249 - Aquaculture/Aquarium Sci II

Credits: 3
Lecture Hours: 2
Lab Hours: 2
Practicum Hours: 0
Work Experience: 0
Course Type: Voc/Tech
This course continues the exploration of aquaculture as it relates to public aquariums, aquatic research facilities and the commercial marine ornamental pet trade. A specific focus on the breeding, spawning and rearing of ornamental marine fishes will be implemented through laboratory exercises and facility site visits. Live food culture and marine invertebrates aquaculture will be studied with hands-on experiences involving both jellyfish and live coral propagations.
Prerequisite: AGS 222
