A widespread but rarely discussed problem is affecting small-scale pond aquaculture globally: most small pond farmers have never calculated their feed conversion ratio (FCR), even when diligently recording feed usage and fish weight.
To address this gap, AquaCulture Pro, a US-based platform built for pond farms operating between three and 50 ponds, launched a free FCR and harvest projection calculator at aquaculture.cloud in early 2026. Since the launch, farmers from nations including Zambia, Guatemala, Honduras, Mexico, Colombia, India, the Philippines, and Panama have used the tool – many discovering their FCR for the first time.
Among them is Euster, who runs Misamfu Aquaculture Fisheries in Zambia. Euster raises two indigenous tilapia species, Oreochromis macrochir and Coptodon rendalli, in earthen ponds, weighing his fish on a kitchen scale and carefully tracking feed usage. However, until utilising the new calculator, he had never connected those records to an FCR figure.
Euster's initial calculation returned an FCR of 5.44 – more than three times higher than a well-managed tilapia pond should achieve. At that level, for every kilogram of fish produced, a farmer spends significantly more on feed than necessary. For a small operation, that gap translates directly to the difference between a profitable cycle and a marginal one.
Part of the explanation lies in the choice of species: Coptodon rendalli is a herbivorous tilapia, poorly suited to the high-protein commercial pellets formulated for Nile tilapia. Farmers raising rendalli on standard commercial feed will almost always see an elevated FCR – not through poor management, but through a mismatch between feed and species that often goes undiagnosed without structured data.
"I was recording my feed and weighing my fish, but I had never calculated my FCR before. When I saw the number I realised I needed to change how I was managing my feed," said Euster, manager of Misamfu Aquaculture Fisheries.
AquaCulture Pro is positioning its platform to help small and mid-scale pond farms track the variables that determine profitability. The system offers feeding logs with automatic FCR calculation, water quality monitoring across multiple parameters, growth forecasting, and harvest planning – without requiring IoT sensors or technical infrastructure.
"Most small pond farmers are making critical decisions about feeding, stocking, and harvest timing without reliable data," said Navaid, founder of AquaCulture Pro, in a press release. "They know their FCR matters, but they have no system to calculate it. We built this to close that gap — starting with making the number visible."
The free FCR calculator is available at aquaculture.cloud with no registration required. The full platform is available from USD 49 per month, featuring a bilingual English and Spanish interface.
