Abstract—
Growth and age of blue antimora were studied in waters of the Flemish Cap (Northwest Atlantic). Bottom trawl catches were represented by specimens aged 2–43 years, with total length of 112–680 mm and body weight of 6–2830 g. Fish at the age of 14–26 years (62% of catches) prevailed. The growth rates of males and females were similar, but males had a slightly shorter life expectancy (the maximum age was 41 and 43 years, respectively) and less average age (19.9 and 22.6 years, respectively). The species growth is best described by a logistic function (coefficients: а = 61.9, b = 5.4, с = 0.1). Comparison with the data from other regions was made using the von Bertalanffy growth equation with the following parameters: L∞ = 142.9, k = 0.01, t0 = −2.9. Blue antimora from the Northwest Atlantic turned out to be the most slow growing compared to the specimens from other areas of the species range.
