First decision

Sex shrimp with stated confidence

You want to classify a shrimp as male, female or uncertain.

Use the whole card. The action stays attached to what must be observed and recorded, plus the nearest inference or action the current guidance cannot support.

Observe first

Use clear lateral and dorsal observations and note size, maturity, abdominal form, ovarian tissue and attached eggs separately.

First action

Assign only the confidence the visible evidence supports and keep uncertain or immature animals unclassified.

Record next

Record image date, view, landmarks used, confidence, later ovarian development, attached eggs, mating or hatch confirmation.

Stop boundary

Do not use colour, size or a vague saddle alone as universal proof of sex, maturity, fertility or reproductive outcome.
