Morphometrics of albacore tuna (Thunnus alalunga) in the Western Indian Ocean




This paper provides information on the length-length (fork-length, FL with pectoral length, PL and first dorsal length, LD1) and length-weight relationships of albacore tuna (Thunnus alalunga) in five regions of the Western Indian Ocean. Data were obtained for a total of 923 female and 867 male albacore, caught by different fishing gears, and sampled from 2013 to 2015. The regression coefficients of the different relationships are presented. Possible causes of variations in length-weight, including tissue weights (gonad, liver and the rest of the viscera), sex and region are assessed using analysis of covariance (ANCOVA) and linear regressions on log-transformed equations of length and weight.
