CV–coefficient of variation; Q1-Q4 (Quartile Q1 and Q3 are the first and third quartiles and Q2 is the median value; Q4 is is the maximum value); Min–Minimum; Max–Maximum; SD–Standard deviation. Attributes are K (growth coefficient); L∞ (Asymptotic length); Lm (Length at maturity); NSM (Number of spawning months); BLD (Body length depth); CPI (Coastal productivity index); MTL (Mean trophic level); Dist (Distribution); Er (Exploitation rate) and Lr (Length at recruitment).
