Set up your first batch
A batch, a cohort of fish stocked together, is the record everything else links to: feed goes to a batch, mortality comes off a batch, and your FCR, growth and margin are all worked out per batch. Set one up first and the rest of the app has something to hang on.
Add a batch in a minute
- Open Batches (Performance) and add one, pick the species (any fish, from the list or your own name), how many, and their average weight if you know it.
- Choose which site and tank it lives in. Not sure of the weight? Leave it, you can add a biomass sample later.
- That's it. You can now log feed, water and mortality against this batch from the daily round.
- You can edit the species or count later from anywhere, nothing is locked in.
Why it drives the numbers
Feed conversion (FCR), growth pace and the value at risk in the water are all computed from a batch's stocking, feed and biomass records. The more of the daily loop you log against it, the sharper those numbers get, and none of it needs re-entering; it's derived from what you already record.
Add your first batch and let the numbers build themselves.
