Four ways in. One farm record.

Water quality without a meter

Landsat-9 and Sentinel-2 pass over every coast on Earth on a fixed schedule and have been recording them for years. Wherever your ponds are, the archive already holds them. We clip that imagery to your exact pond outline.

Eleven indices per clear pass: surface temperature straight off Landsat-9's thermal sensor, turbidity and clarity, salinity, pH and alkalinity, chlorophyll-a and floating algae for bloom risk, dissolved organic matter and suspended solids for ammonia risk, and the land use around your farm. Each one is labelled in the app with how it was obtained.

Because the archive already exists, a farm can be read backwards — a season you did not measure at the time is available now.

What you get. A water record for every pond you farm, stretching back through seasons you never measured, with no meter to buy and nothing installed in the water. Keep your meter on the bund for dissolved oxygen — BlueSat handles everything the satellites can see.

Ponds mapped by a person

A farm buddy visits, traces each pond on satellite imagery while standing at the water, and records the details that the rest of the system depends on.

Water spread area is calculated from those traced outlines. It is never typed into a form, because regulators set fees, caps and permits on that figure — India's Coastal Aquaculture Authority among them — and a typed estimate is indistinguishable from a measurement once it has been stored — including to the person who typed it.

• Title or survey number taken from your land record, entered once
• Pond boundaries traced on imagery, on site
• Farm coordinates and area derived from the outlines
• Login handed over in person; there is no signup form

What you get. A water spread area you can put in front of whichever authority licenses your farm, pond boundaries accurate enough to clip satellite imagery to, and a login in your hand before your buddy leaves the farm. One visit, and the setup is done.

Records that hold up in front of a regulator

Every coast licenses aquaculture through somebody, and they all ask for the same handful of figures: who owns the land, how much water sits on it, what is in the water and how densely. Those are the figures the app is already keeping, as a by-product of ordinary use rather than assembled in a panic before an inspection.

India's Coastal Aquaculture Authority is the first regulator implemented end to end: its Form I fields — survey number, water spread area, species, stocking density — are tracked by name, and registration expiry is watched. Elsewhere the same record exports as a spreadsheet you can take to your own authority; we add a country's form properly when we open there, rather than claiming a filing we have not read.

On density, the app is deliberately conservative everywhere. It warns above 60 post-larvae per square metre, which is India's cap for L. vannamei. International practice calls 70–100/m² ordinary, so outside India read the band as a caution rather than a legal limit — and tell us your cap, because a wrong number here can cost a farmer their licence.

What you get. The figures a regulator asks for, assembled and current, density flagged as you stock, registration expiry watched, and the whole record exportable — so an inspection is a morning of paperwork you already have rather than a scramble.

Cycles, feed and what the crop actually did

Stocking to harvest, pond by pond, with the feed and the growth samples in the same place as the water readings.

Feed conversion ratio and survival are calculated from your own logs, crop by crop — real figures for your ponds, not an industry average. Every number on the screen traces back to something you or your buddy actually recorded, which is what makes it worth stocking the next cycle against.

Once a cycle is finished you can look at the water through a season whose outcome you already know. That is how a pattern becomes a rule you can farm by.

What you get. FCR and survival calculated from your own crop rather than from a rule of thumb, cycle against cycle, so you can see which ponds and which practices actually pay — and carry that into the next stocking.
