Sustain runs a sustainable fish farm in Tanzania. With Aquasmart, the operations team records its data on one shared platform instead of paper logbooks.

Sustain's farms generate a lot of data every day: feed amounts, mortality, water quality, samples and biomass. For a long time, most of it went into paper logbooks, cage by cage. Figures such as eFCR were calculated later, with plenty of copying by hand. Four roles also needed different answers from the data. The production team focuses on today's work at each cage, while management and investors look at the whole farm.
In the workshops, we mapped a typical day on the farm step by step: planning, feed delivery, feeding, mortality, water quality and performance monitoring. Aquasmart follows that routine. Each value is entered once, directly in the platform, instead of being written in a paper logbook and copied over later.
The dashboard calculates key figures for each cage from the day's entries. These support daily monitoring, so changes stand out straight away instead of getting lost in a table.
Alerts about water quality, fish health and feed stocks show where attention is needed today. The team can act while there's still time, rather than waiting until the figures have been analysed.
Since launch, Sustain's farm team in Tanzania has been working with Aquasmart. It took three months to go from kick-off to a working MVP, with six areas giving four roles access to the same data. The pilot was designed to show what works in daily use and what's still missing. Aquasmart runs on Next.js and Supabase, with separate staging and production environments.
