Effect of Ballast Water on the Growth of Two Aquatic Macrophytes (Azolla pinnata R.Br and Lemna paucicostata Hegelm)
The study investigated the effect of ballast water on the growth of two aquatic macrophytes, Azolla pinnata R.Br. and Lemna paucicostata Hegelm. The ballast water used for this study was sourced from MTCRARROCH vessel which berthed in Koko Port. The macrophytes were grown at different concentrations (25%, 50%, 70% and 100%) of ballast water, using distilled water as control (0%). The experiment lasted for twelve (12) days. There was increased growth in both macrophytes with increasing concentration of ballast water.
