Abstract:
This study describes and provides a morphometric analysis of the otoliths sagittae, asterisci and lapilli of the Pacific jack Caranx caninus Günther, 1869, in the tropical Mexican Pacific. The relationship among length, width and weight of the sagittae is expressed by the following equations: y = 0.772x0.950 (rostrum-antirostrum), y = 0.480x0.791 (rostrum-width) and y = 0.00006x2.595 (rostrum-weight). In the case of the asterisci: y = 1.704x1.077 (length-width) and y = 0.00048x2.478 (length-weight). For the lapilli y = 1.047x0.949 (length-width) and y = 0.00028x3.047 (length-weight). The growth of these otoliths was also related to the length of the fish. The average length was calculated for each of the six growth rings identified in the sagittae and the asterisci; the results are: 0 = 6.33 cm, 1 = 15.09 cm, 2 = 32.19 cm, 3 = 41.50 cm, 4 = 48.17 cm, 5 = 55.58 cm and 6 = 58.75 cm.
