The increasing pressure to convert them into aqua-cultural areas and over-harvesting of resources from the ecosystem threatens their existence. The irony of the situation is that the conversion of mangroves for aquaculture is detrimental to the very same activity as the shrimp fry (baby shrimp) availability decreases, as the mangroves are the natural wild fry collection habitats. The overdose of chemical fertilizers and pesticides not only destroy the aquaculture farms but also become detrimental to the remaining mangrove ecosystems in the vicinity.
Further, these mangrove species are sensitive to excessive siltation or
sedimentation, stagnation, surface water impoundment and major oil
spills. Salinities high enough to kill mangroves result from reductions
in the freshwater inflow and alterations in flushing patterns
Increasing development and industrialization in the vicinity is further
affecting this ecosystem.
