ABSTRACT Black mangrove ( Avicennia germinans ) were grown from seed in a closed synthetic seawater system to a maximum height of 165 cm and trunk diameter of 20 mm in 24 months. Plants were maintained in glass aquaria in 63 mm of crushed coral and shell substrate and received continual flow from a 28,387 liter system. Seedlings were planted in aquaria 18, 30 and 46 cm deep but only those in 18 cm aquaria survived. The entire system is housed in a modified greenhouse and only ambient light was provided. Average salinity was 27 ppt (range 17–34 ppt), temperature 26.2°C (range 21.3 to 30°C), pH 8.05 (range 7.8‐8.3), nitrate‐N 52.3 ppm (range 38–66 ppm) and phosphate‐P 0.568 ppm (range 0.078‐1.080 ppm). Additions of a trace metal solution were made during the last 14 months.
