How to Handle Uncertain Lineage in Purchased Shrimp

Record what the seller states, what you observe, and what remains unknown as separate facts.

Keep source information intact

Save the listing or seller’s name, stated color line, and date of purchase. Do not rewrite the seller’s label as a verified pedigree.

Ask for available lineage information before purchase if that matters to your project, but understand that it may not exist.

Photograph animals under consistent light once they have settled. Record variation without assuming that every shrimp came from the same parents.

A visually similar group can still have uncertain ancestry. Appearance alone cannot establish a complete pedigree.

Call the group a color project or seller-labeled line if parentage is not documented. Keep the uncertainty visible in your records.

This honest label prevents future generations from being described more confidently than the evidence allows.
