Thalassia testudinum Konig and Sims and Halophila engelmanni Aschers. (Hydrocharitaceae); Diplanthera wrightii (Aschers.) Aschers., Ruppia maritima L., and Syringodium filiforme Kutzing (Potamogetonaceae) are the major plants of the highly productive estuaries along the Texas coast. When transplanted to outdoor ponds and to controlled growth rooms, the greatest tolerance to increasing salinity was shown by Diplanthera. Lesser salinity tolerance was shown by Thalassia and Ruppia. Although survival was not complete under all transplant conditions for Syringodium, it showed least tolerance of high salinity. Halophila survived sporadically in the study but showed active growth at high salinity. The distributional patterns of these species in Redfish Bay are partially correlated with their salinity tolerances.
