  • Protein grown in Pakistan

    Duckweed from our own raceways outside Islamabad, not soybeans shipped across an ocean.

  • Up to 40% crude protein

    In our dried duckweed, dry basis, across lab-tested batches.

    Measured by a third-party laboratory on a specific sample.
  • No fishmeal. No soy.

    GreenFin replaces both with duckweed protein.

Kilo for kilo.

Our duckweed against the ingredients Pakistani fish farms buy today.

1 kg of our duckweed has the protein of 2½ kg of rice polish.

Protein as sold: our duckweed powder is about 31%; the others are from FAO carp feed tables.

  • 3.8 ppb

    Cleaner than the feed you buy

    Total aflatoxins in our duckweed. More than 5 times under the 20 ppb US FDA limit for animal feed. A national Pakistani survey found cottonseed meal averaging 32 ppb.

  • Up to 10×

    The protein of soybean, per acre

    Published estimates put duckweed at up to 4 tonnes of protein per acre a year. Soybean manages about 0.4.

  • Every 3 days

    A harvest, not once a season

    We harvest more than 30 times in the time it takes one soybean crop to grow.

  • 2×

    The lysine of maize protein

    Lysine is the amino acid fish run short of first on grain-based feed. Duckweed protein carries about twice as much as maize protein.

  • Clean

    Tested for heavy metals

    Grown on fresh borewell water, not wastewater. Lab tests found no heavy metals.

  • Zero

    No gossypol. No glucosinolates. No wild fish.

    The toxins that cap how much cottonseed and mustard cake you can feed aren't in duckweed. And with no fishmeal, no ocean fish go into the bag.

  • Natural colour

    Lutein, zeaxanthin and β-carotene

    The same natural pigments that turn egg yolks golden and keep goldfish and koi bright.

How it's made

  1. Duckweed fronds on the surface of a raceway, seen from above

    01 Duckweed covers our black-lined raceways near Islamabad.

  2. A harvest scoop lifting duckweed from the raceway

    02 We skim it off the surface and leave enough to regrow.

  3. Freshly harvested duckweed spread out to dry on a tarpaulin

    03 The harvest is dried into a protein-rich meal.

  4. GreenFin pellets

    04 The meal is formulated and pressed into GreenFin pellets.

Coming soon.

Every feed in the range is on its way, with Carp Polyculture and Tilapia already on university trials. Message us to be first in line, or buy our duckweed powder today.
