Estimated abundance of Antarctic blue whales The estimated pre-exploitation abundance (K) was 280,471 in 1904. The population trend in Figure 1 shows a steady and sharp decline, interrupted only by the Second World War. From 1970, the population grew from the assumed minimum of 1000 to about 7150 in 2021. Growth rates, yearly population changes and catches are illustrated in Figures 2 and 3.

This study delves into blue whale population dynamics and demographic modeling, emphasizing the repercussions of historical industrial hunting and the subsequent population decline. Employing continuous demographic models, we calculate intrinsic growth rates, construct life tables, and formulate stable population models. The research underscores th...
