Re: constructed wetland for Aquaculture
Dan,
Assuming that your water is above 15-degrees C and well lit, Hygrophila
polysperma and Vallisneria gigantea always seem to be very fast growing,
high nitrate tolerant plants. Both grow well in fast moving water with
minimal dissolved oxygen.
In very hard water, or slightly salty water, Elodea and Egeria do well, but
they tend to need cooler water, say 10 to 15-degrees.
Alernatively, surface plants like water hyacinth and Pistia strationes grow
very quickly, far faster than submerged plants, and are indifferent to
water quality.
Regards,
Neale.
