NOAA Photo Library Image - fish2112

Photo #2. Compare this cross-section to the previous image. Notice the greater width of the outer band. This is because the first cross-section was from a bluefin tuna caught in June while the second was from a tuna caught in November. The wider area represents a long period of high food intake during summer/ autumn months. These images are greatly magnified.
