We automate high-density fish and shrimp farming

One low-cost sensor suite covers the whole farm. Our AI diagnoses faults and tells farmers what to do over WhatsApp.

The whole farm runs on one sensor suite

The handheld monitoring unit

Dissolved oxygen, pH, total dissolved solids and temperature are read across every pond on the farm, and the unit returns to a solar dock to charge. One suite costs a fraction of a fixed sensor array, which is the reason a smallholder can afford one at all.

See it in action

Automation in three simple steps

01 Sense

One handheld suite reads dissolved oxygen, pH, TDS and temperature across every pond, then returns to a solar dock to charge.

02 Diagnose

The inference engine ranks likely fault causes from field data, so a drifting number becomes a clear explanation instead of a guess.

03 Act

Farmers get the next action in WhatsApp, in their own language. Owners oversee production from the dashboard.

A low-cost handheld unit replaces the fixed sensor array

Four probes, a solar dock and a printed enclosure make up the whole instrument. Nothing in the build is exotic, and that is deliberate, because the intelligence lives in the software rather than in the hardware.

A closed feedback loop improves the farm every cycle

The full system loop: farm to handheld unit to IoT dashboard to the WhatsApp farm chat agent and back to the farm

An AI agent handles every conversation with the farmer

Operators never touch a dashboard. The agent sends each instruction in their own language through WhatsApp and takes their readings back the same way, which keeps the field workflow as simple as a chat. Owners get the dashboard instead, where they oversee production across ponds and analyse the data behind it.

One unit covers every pond on the site

The unit moves between ponds rather than sitting in one, so a single suite reports the whole farm through the same agent. Adding a pond does not mean adding hardware, which is what makes cost per pond fall as a farm grows.

From the pilot

One commercial cycle produced this

Sixteen weeks of Nile tilapia at the pilot, against a conventional flow-through pond over the same period.

47% less feed for the same weight of fish

Feed conversion of 0.846 against a typical flow-through 1.6. Feed is the largest running cost on a fish farm.

25 kg/m³ stock density
held for a full cycle

Ten times the fish in the same water versus roughly 2.5 kg/m³ traditional, at 84.89% survival.

Biofloc holds ten times the fish in the same footprint

Microbes convert fish waste back into protein in the water column. Ammonia stays down while stocking density goes up and water use drops. The biology has been proven for years.

  • HDPE-lined tanks run continuous active aeration
  • Floc recycles waste nitrogen into feed in the water column
  • Water exchange is a fraction of a conventional pond
  • One missed overnight oxygen crash still costs the whole harvest

High density has always demanded an expert on site

That labour constraint keeps intensive farming out of reach for independent producers. Software removes it.

United States

Consumption rises every year and between 75 and 90 percent of it is imported. Domestic producers cannot reach intensive density because the labour to run a farm at that level does not pencil out.

Indonesia

There are 6.5 million ponds and three quarters of them run at low density. The infrastructure is already built and already paid for, which makes Indonesia the fastest place in the world to add density.

The pilot beat its target growth curve

A full commercial cycle was tracked week by week against the target curve for Nile tilapia. Realised biomass finished ahead of target at a feed conversion ratio below 1.0.

Chart of average fish biomass over 17 weeks. The realised commercial biofloc curve finishes at 231.0 grams against a target of 222.7 grams, at a mean feed conversion ratio of 0.846, 103.73 percent of the growth target and 84.89 percent survival

The system runs on working farms today

We work with farmer cooperatives and independent producers across West Java in Indonesia and in Escondido, California, running the full stack from monitoring on a solar dock through the inference engine to the operator dashboard. We are looking for new farms to work with.

Research collaboration

Expert input is built into the product

Floc.ai runs an international cross-sectoral research collaboration spanning three countries. Funded student engineering and aquaculture science feed directly into the knowledge base, so every new farm and every new institution makes the model better for every farm already on the network.

Every institution adds engineering capacity and field data at the same time, so the model improves for every farm on the network. That compounds.

A number that drifts is not a fault. Readings pass through a fuzzifier and a knowledge base built from field data, and the engine ranks the likely causes across its fault classes before deciding whether the answer is guidance to the farmer or a direct change to the aerators.
