Growth performances in scombrid species including all fishes in FishBase, illustrating the high growth performances of scombrids.

<p>(A) Auximetric plot comparing the growth performance of scombrid species (black circles) with that of fishes in general (grey circles). Fish data extracted from FishBase as August 2012. The growth space for the main four taxonomic groups of scombrids, tunas, bonitos, Spanish mackerels and mackerels, are also illustrated (colored ellipse curves). (B) The growth performance index Ø′ (defined as Ø′ = log₁₀<i>k</i>+2log₁₀<i>L_∞</i>) of scombrid fishes compared with the average growth performances in fishes in FishBase (average growth performance is 2.7±0.3, grey band area).
