GreenFin
Pelletized fish feed, formulated around duckweed protein from our lined raceways near Islamabad. Three lines, Carp Polyculture, Tilapia and Ornamental, all made in pilot batches.
Pack concepts, modelled in 3D. Production packaging may differ.
GreenFin Carp Polyculture
For ponds stocking several carp species together, such as rohu, mrigal and grass carp.
GreenFin Tilapia
For tilapia ponds and tanks.
GreenFin Ornamental
For aquarium and ornamental fish, in a smaller pack.
-
Duckweed protein
Grown on our lined raceways near Islamabad, then dried to a meal.
A physical fact about our ponds and equipment. -
~31% crude protein
As-is, in one recent pilot batch. Further testing is underway.
Measured by a third-party laboratory on a specific sample. -
No fishmeal. No soy.
The formulations in our university feeding trials use neither fishmeal nor soybean meal.
What's in it
GreenFin starts with dried duckweed meal from our raceways, blended with other feed ingredients and pressed into pellets.
The formulations in our university feeding trials use neither fishmeal nor soybean meal. We keep full formulations confidential; research partners can see them under a non-disclosure agreement.
Current measurements
These are measurements so far, not a finished specification. Each carries a label for how it was measured.
| Measure | Value | Basis | How we know |
|---|---|---|---|
| Crude protein, GreenFin pellets | ~31% | As-is, one recent pilot batch | Measured by a third-party laboratory on a specific sample. |
| Crude protein, dried duckweed | 35–40% | Dry basis; range across tested batches, varies with season and growing conditions | Measured by a third-party laboratory on a specific sample. |
| Aflatoxin, duckweed biomass | 3.8 ppb | One tested sample | Measured by a third-party laboratory on a specific sample. |
Still being measured
- Amino-acid profile, especially methionine
- Wet-chemistry (AOAC) confirmation of protein values
- Pellet durability, water stability and sinking behaviour
- Digestibility
- Heavy metals and anti-nutritional factors
- Shelf life in storage
We'll publish a full spec sheet once these are complete.
In feeding trials now
University partners are testing GreenFin with fish in tanks. Results appear on our Evidence page once each trial has been analysed and cleared for publication.

How it's made
-
01 Duckweed grows on lined raceways near Islamabad.
-
02 Fronds are skimmed from the surface at harvest.
-
03 The harvest is dried into a meal.
-
04 The meal is formulated and pressed into pellets.
Availability
GreenFin is made in pilot batches, currently for university feeding trials. Feed mills and fish farms can ask us for a sample, and farm partnerships are being set up.
