Water hyacinth can double its biomass in eutrophic waters every 3 weeks given the right day length. The only practical way to significantly address it is by limiting the nutrients into freshwaters from agri fertilizer runoff and from human wastes, esp. urine. There are plenty of uses from char-bricks, to soil compost supplement, to biogas with cow/pig manure, to basket and rug making. Yet none of these uses address the long term issues of shallow water annoxia, biodiversity loss, and river/creek/lake navigation impediment. The hyacinth is there mainly because of the nutrients added by human activities.
