How to measure fish
You should measure a fish with its mouth closed while lying it flat on a measuring device to comply with NT size limits.
For fish with a lower jaw longer than the upper jaw, like barramundi or cod, overall length is measured from the tip of the lower jaw to the middle ray of the tail fin.
For fish with an upper jaw longer than the lower jaw and with tail fin rays that appear to be the same length or concave, such as red emperor and mangrove jack, you should measure from the tip of the snout to the longest part of the tail fin.
For fish with a forked tail, like blue or king threadfin, you should measure from the longest part of the head to the fork of the tail. This is known as the fork length.
