Reinventing aqua nutrition from the protein up
For millions of years, aquatic species evolved on insect protein. The modern aquafeed industry replaced it with soy, corn and fillers.
Zewa Ecosystems, founded in Kerala, is rebuilding that formula from first principles — feeds that work with fish biology, not against it.

Innovating feed systems to make animal nutrition superior, sustainable and future-ready
Advancing insect protein technology to develop and commercialise scientifically validated formulations which will make animal nutrition sustainable and future ready
A $500 billion industry, built on the wrong protein
The global animal feed industry is worth half a trillion dollars, and most of it runs on soy and corn — crops chosen for cost and scale, not for how aquatic species actually digest.
Zewa went back to the biology. Every formula is anchored in Black Soldier Fly protein, farmed in-house at India's first data-centric insect farming plant, and validated by independent NABL-accredited laboratory testing.
- More nutrition absorbed per feeding.
- Less ammonia in the tank.
- Healthier fish on fewer meals.
Two-thirds of global deforestation is driven by protein production
Zewa's entire model is built to push against that. BSF larvae are raised on organic bio-waste — upcycling what would otherwise decompose in landfill into high-quality protein, using a fraction of the land, water and energy that soy or fish meal demand.
- 1
Waste in
Organic bio-waste destined for landfill becomes larval substrate.
- 2
Protein out
Larvae convert it into dense, highly digestible feed protein.
- 3
Fertiliser back
Frass, the larval by-product, returns to the soil.
“From waste in, to protein out, to fertiliser back — nothing is lost.”
Four principles, applied to every batch
- 01
Evidence over claims
Every nutritional value is NABL-accredited laboratory tested. Nothing ships on marketing alone.
- 02
Biology first
Pellet size, sinking profile and protein ratio are calibrated to each species' actual anatomy.
- 03
Nothing wasted
Bio-waste becomes protein; the by-product becomes fertiliser. The loop closes by design.
- 04
Traceable end to end
Bio-secure production, from substrate preparation through to the packaged batch.
Scientifically validated at leading research institutes
