Sustainability
Our philosophy is simple
Don't manufacture nature. Work with it.
For us, sustainability isn't about adding more technology to make an intensive system slightly less intensive.
It's about asking a more fundamental question:
What if the lowest-impact farm is the one you don't have to build?
That is the Marisvitae approach—wild-minded aquaculture, rooted in existing ecosystems, designed to leave as little behind as possible.
The lightest footprint in the seafood aisle
Because we take an existing ecosystem, rather than manufacture the prawn's environment, the usual costs of environmental effects simply don't exist here.
The result is a fundamentally different approach to aquaculture: produce more from what already exists, rather than continually building more to produce.
Sri Lanka's dry-zone reservoir system is one of the oldest engineered landscapes on earth. This is the ecosystem, the geography, and the community structure that make Ceylon Giant Prawn what it is.
We also keep stocking densities and farming practices aligned with the capacity of each individual water body.
The goal isn't maximum production at any cost. It is productive balance—harvesting a valuable food while respecting the ecology that makes that production possible.
Four Principles
No supplemental feed
Once the Post-Larve are released to the wild, Prawns eat what the reservoir grows. No fishmeal, no soy, no feed-manufacturing footprint — and no pressure on wild fish stocks harvested to feed farmed ones.
No habitat converted
We work in reservoirs that already exist. No mangroves cleared, no land taken, no wetlands drained to make way for production.
No discharge, no chemicals
There are no ponds to flush and no effluent to release. No antibiotics, hormones, or growth chemicals ever enter the water.
Low energy, low water
No aeration, no pumping, no draining. The monsoon fills the reservoir; the sun and the food web do the rest of the work.
SDG Alignment
SDG 6 — Clean Water → Working within existing freshwater reservoirs and prioritising productive and responsible use of freshwater resources and ecosystem management.
SDG 12 — Responsible Consumption & Production → Producing seafood using existing ecosystems rather than creating new intensive production infrastructure.
SDG 15 — Life on Land → Stewardship of freshwater ecosystems. The model depends on maintaining healthy freshwater ecosystems and avoiding unnecessary land conversion.
SDG 13 — Climate Action → Avoiding construction, land conversion and intensive infrastructure, reducing environmental impacts.
