It also provides breeding
space and sanctuary for birds, fish, snails, insects and other
wildlife[59]. Zhao et al.[60] found that nutrient
concentration, mean number of ramets, mean height and total
biomass of water hyacinth significantly increased with
increasing nutrient level. Shorter time is required to reach
maximum biomass yield in summer with high growth rate
[61] whereas optimal water temperature for its growth is
28-30 ℃. Temperature above 33 ℃ inhibits further
growth[55]. If temperature of -3℃ lasts for 12 hours, it will
destroy all leaves and temperature of -5 ℃ for the period of48 hours will destroy whole plant[48]
