dc.description.abstractThe von Bertalanffy growth parameters for chub mackerel (Scomber japonicus) from the NW Mediterranean, along the Catalan coast (Spain), were estimated. These results constitute the first estimated values for chub mackerel in this area and were as follows: L∞(cm) = 39.75; K (years-1) = 0.298; t0 (years) = -1.40 (for age groups 0 to 8). These results were compared with the estimated growth parameters for the chub mackerel that inhabits other two regions: NE Atlantic (Azores) and SW Atlantic (Argentina). Significant differences in growth curves between regions were found when the growth parameters, L∞, K and t0, were simultaneously compared. When comparing the growth parameters L~! and K individually, significant differences between regions were also verified. To establish the causes in the geographical variations in the growth, some local environmental factors were analyzed, in particular, the effect of surface water on the index of physiological activity of fish (K). The observed geographical differences indicate that chub mackerel from higher latitudes reach a lower asymptotic length but have a higher K than chub mackerel from lower latitudes. No direct relationship could be established between K and the average annual water temperature in the different regions of their world distribution. On the other hand, food resource quality and availability appears to have a greater influence on growth in chub mackerel.en
