The prime logic of suggesting instant ‘Identification of fish in the field’ is because of the fact that the colourful adornments of FISHES can only be recorded when they are live. It is not to be emphasized that most fishes have their Genus/Species specific colourations which mostly fade out on preservation over a period of time. Other taxonomic exercises (like meristics or morphometrics) can be performed even after preservation but observing and recording characteristic colour patterns is possible in the field itself.
