How to Measure Your Catch
How to measure finfish
For Massachusetts marine waters, the minimum size for fish (exceptions listed below) is the greatest straight line length (not curved over the body) from the anterior tip of the jaw or snout (mouth closed) to the farthest extremity of the tail. Fish should be firmly grasped with both hands for proper measuring. Care should be taken so that the head firmly contacts the zero mark on rulers and tapes simultaneously with the tail extremity. For fish with forked tails, the upper and lower fork may be squeezed together to measure the tail extremity.
Black sea bass if the tail filament (tendril) is present, it is not included in the total length measurement.
Billfish (swordfish, sailfish, marlin) are measured from the tip of the lower jaw to the tail fork
Sharks are measured from the tip of the snout to the fork of the tail.
Tunas measurement is taken in a line, tracing the contour of the body from the tip of the upper jaw to the fork of the tail, which crosses the dorsal insertion of the pectoral fin and the dorsal side of the caudal keel.
