Hybrid striped bass ([male]Morone saxatilis [female] Morone chrysopos) were successfully cultivated in two separate 48 day trials (t1 and t2) with seedlings of lettuce (Lactuca sativa cv. Rex) and pac choi (Brassica rapa cv. Win-Win) within a shared recirculating aquaponic system. It was determined that fish stocking density had no significant effect on the mean yield of lettuce and pac choi biomass in t1. Stocking density did have a significant effect on the elemental nutrients generated within the aquaponic systems. A nutrient deficiency was exhibited by the leaf tissue of pac choi grown with fish stocked at low a density (0.82 kg/m3). The deficiency could not be differentiated between Mg or Mn. A higher fish stocking density (1.64 kg/m3) effectively provided the essential nutrients required by plants for normal healthy growth. A decrease in day length and lack of supplemental lighting contributed to a significant decrease in the mean yield of lettuce and pac choi biomass in t2.
