Introduction: In collaboration with ICUN and the Cat Ba Island Heritage Management Board we have completed a survey of the polystyrene used on all the floating houses and aqua farms in the Lan Ha Bay archipelago. Polystyrene has far reaching implications on marine eco systems as studies have shown that juvenile fish, when exposed to polystyrene, start preferring it over their natural food sources. This makes them more susceptible to predators and also decreases their birth and first day’s survival rates. Polystyrene is also classed as a carcinogenic substance that can cause cancer in humans. There is a significant amount of polystyrene debris in the bay that is in various stages of breaking down and being absorbed back into the eco system. If left unchecked this has the potential to turn into an ecological disaster, both for the marine species and humans that depend on them for survival.
Scope of Project: In collaboration with ICUN and the Cat Ba Island Heritage Management Board we have completed a survey of the polystyrene used on of the all the floating houses and aqua farms in the Lan Ha Bay archipelago. The cost of this project is likely to exceed $1 000 000.00 due to the large volumes of floating houses in the area.
Duration: Long term due to complexity and cost
