Likely will be dome shaped. Are the largest individuals being caught by traps for each species?

The effect of mesh size on mean length at first capture {L:) was examined and Munro's model, L: = dD + v (Munro, 1983) where D = maximum aperture of the mesh, and d and v are constants describing the length to maximum body depth relationship for the species.
