Individual leaves grow to about 4" with a rhizome of up to 2 ft long. Light was considered the more important factor controlling growth, since the waters of the estuary are generally turbid, and subject to sudden increases in turbidity. Uniform stands of Halophila ovalis reached a biomass of up to 120 g dry weight (DW) m−2 in late summer/early autumn, and maximum productivities of up to 40 g DW m−2 day−1 in summer. and B.
