More turtle grass
As far as I know, the only successful transplantings of turtle grass
occured using a plug technique. This minimizes root trauma, but on
the negative side it makes turtle grass hard to collect intact, and
forces you to move large amounts of sediment. It also creates a large
disturbance at the collection site.
Other species (Halodule and Zostera) have been successfully
transplanted using bare shoots, but these are pioneer species, while
Thalassia is a climax species.
I may be wrong, but I think Thalassia REQUIRES an anaerobic substrate,
which may explain why only the plug technique works, and also why
turtle grass grows poorly in disturbed sediments. I have personally
measured 1.7 mM H2S within 5 cm of the sediment surface in healthy
One of my references reports 10 months until new shoots are observed
in transplanted Thalassia. Also, cuts from boat propellers in shallow
turtle grass beds can take up to five years to recolonize.
Thalassia may not be a good choice for aquarium cultivation, but the
other species may work.
