GROWTH OF ATLANTIC BLUEFIN TUNA DETERMINED FROM THE ICCAT TAGGING DATABASE: A RECONSIDERATION OF METHODS

yr -1 (SE = 0.005) and 364.9 cm FL (SE = 19.0), respectively. These could be used in conjunction with an estimate of t0 of -1.04 yr obtained from modal progression analysis. The L∞ is lower than Turner and Restrepo (1994) but higher than other growth curves. Overall growth from tagging data may be useful, particularly for 2-10 year old fish which constitute the main ages tagged and recaptured and may be underrepresented in modal progression or hard parts or for which aging error or aging bias could be high.
