Pacific White Shrimp
Pacific White Shrimp is one of the most widely cultured species in the world, and is the number one consumed seafood product in the United States. Recent interest in shrimp production in Iowa and the North Central Region of the US has prompted the development of aquaculture techniques in indoor RAS.
Barramundi is a species being grown on a large scale for food in Iowa. Research has been conducted to determine their ability to thrive in our aquaponics research facility as nutrient generators for various leaf and fruit crops.
Tilapia is a very easy fish to grow because of their hardiness, ease of reproduction, and ability to grow quickly on feed. Research has been done on diet formulations and probiotics to enhance gut health and growth of tilapia. Additionally, tilapia have been grown in our aquaponics research facility as nutrient generators for various leaf and fruit crops.
Fathead minnows are commonly cultured as baitfish because of their small size and reproductive habits. Student research has been conducted to determine whether the presence of a substrate to mimic aquatic vegetation in RAS systems improves minnow grow, survival, and reproduction.
