Unintended evolutionary consequences of a minimum landing size regulations: Evidence and implications of fisheries-induced evolution
Fig 2
Variation in the average total estimated length of Dentex gibbosus, Diplodus cadenati, Lithognathus mormyrus, Sparisoma cretense, and Epinephelus marginatus photographed between 1960 and 2022.
The brown dashed line represents the linear regression fit, while the orange line shows the non-linear GAM model fit (confidence band). Horizontal lines indicate size reference points: solid and dashed lines represent the L50 and L95, respectively, for females (orange) and males (green). L95 is not available for Ephinephelus marginatus, which is why it is not shown in the figure. The solid black line represents to the legal Minimum Landing Size (MLS) in the Canary Islands. Lithognathus mormyrus does not have a MLS regulation.
