Here is Thailand there is a lot of aquaculture going on. Almost all of
Thailand's fish and shellfish (shrimp, mussels, oysters, squid,
cuttlefish) come from such farms and the countryside is littered with
them. My practice has been to enclose the entire area including the
ponds and buildings and tag it landuse=aquaculture. Then if I choose
to take the time to trace out individual ponds within those areas,
which I often decide not to bother doing, I would tag them as
natural=water, water=pond.
I honestly don't see the need for another top-level tag for this
purpose. An aquaculture operation almost always involves some dry
land, often quite a lot of it, and processing buildings so the
landuse tag would seem perfectly suited in such cases.
There are the ones in the sea .. well off the coast, others are located
in rivers ... these would be navigation hazards. Not too concerned with
ones on or even adjacent to land.
My only other comment is that the use of natural=water to describe
these, or any, man_made ponds or reservoirs has always seemed, well,
unnatural (pun intended) but I think changing that tagging methodology
at this point in time will never happen. LOL
With you there .. the 'natural' key is a bad term. Its values should be
split between landcover and landform. A landform of a peak, saddle etc
could have a landcover of wood, grass etc.
Humm possibly the landuse key is not what is wanted either ... as it is
being used on water too ... possibly landuse should be humanuse ?
Best,
Dave

Hi,
There are a number of instances of the tag landuse=aquaculture
present on water.
Specifically landuse=aquaculture with produce=oyster.
I think these would be better tagged wateruse=aquaculture.
The landuse tag may have been used as that is what is available on
the wiki and it may get rendered.
Oysters are not the only aquaculture activities taking place on
water ... fish farms too where the fish are restrained in nets.
e.g.

And some crustaceans too.
While some aquaculture does take place on land (e.g. in tanks) ..
the larger installations are usually in water (sea, river, lake or
dam).
Thoughts?
