7-day course that will provide in-depth knowledge of the principles and practical application of the aquaponic and biofloc tank culture systems that have been developed at the University of the Virgin Islands. Participants will be introduced to a variety of system designs that maintain water quality by various solids removal techniques and by hydroponic plant culture (aquaponics), a suspended growth process (biofloc tank culture) or fixed-film nitrification. Fish production instruction will be conducted using both the Nile tilapia (Oreochromis niloticus) and red tilapia. Hydroponic plant production will focus on vegetables, culinary herbs and ornamental flowers.
