Proper Measurement Techniques for Marine Catches in Massachusetts

Standard Measurement Method

Massachusetts How to Measure Your Fish

In Massachusetts marine waters, the regulation for measuring most fish species requires using the total length method. This approach ensures uniformity in size regulation enforcement and conservation efforts. To accurately measure your catch:

  • Total Length: Measure the fish from the anterior tip of the jaw or snout, with the mouth closed, straight to the farthest point of the tail. This measurement should be a straight line, not along the body's curve.
  • Technique: The fish must be laid flat, preferably on a measuring board, with the mouth closed. Ensure the fish's head is firmly against the zero mark on your measuring device, and the tail is fully extended to capture the greatest possible length.
  • Handling: Hold the fish securely with both hands to keep it straight and properly aligned with your measuring tool.

Specific Species Exceptions

Certain species have unique characteristics requiring adapted measuring techniques to accommodate their body shapes and sizes effectively:

  • Tunas: Measure using the curved fork length, following the body's contour from the upper jaw tip to the tail fork. This method accounts for the tunas' streamlined shape and the importance of their fork length in determining size.

  • Black Sea Bass: Measure from the snout or jaw tip (with the mouth closed) to the tail's farthest extremity, excluding the tail filament. This acknowledges the unique body features of the black sea bass, including the tail filament which is not considered part of the standard length measurement.
