Three sites in the Indian River, Florida were studied to determine primary production
in seagrass meadows. Production rates were obtained for 3 species of seagrasses
(Thalassia testudinum, Syringodium filiforme and Halodule wrightii), associated epiphytic flora,
benthic microalgae and phytoplankton. Photosynthetic rates for Indian River seagrasses in March
and July ranged between 0.009-0.395 mg C/g dry wt-h for H. wrightii , 0.005-0.79 for T.
testudinum, and 0.009-1.72 for S. filiforme. Epiphytic productivity per g dry wt varied considerably
between stations and from season to season. Productivity maxima for H. wrightii and S.
filiforme occurred at the Jim Island station; Thalassia testudinum demonstrated maximum
photosynthetic response at Link Port. Phytoplankton, benthic microalgae and epiphytic production
were similar at each station and increased slightly from March to July. However, their absolute
importance in community productivity changed dramatically depending upon the contribution
of the seagrass species. Florida Atlantic University.
