Comparison of the kernel density estimate (KDE) probability function using the mean bandwidth for the lengths of all fish by Location (pipeline and off-pipeline) and depth using raw fish length data.

Shallow water deployments are divided into ‘sand’ or ‘benthic biota’ determined by the dominant habitat seen on video footage. Solid and dotted lines present the KDE probability density functions that approximate the length-frequency data of all fish on and off-pipeline, respectively. The shaded band represents 1 SE either side of the null model of no difference between either KDE for each Location. Significance was based on permutation tests of the area between the probability density functions. Vertical lines represent the median fish length from all fish measured on and off-pipeline.
