A Comparison of Fishes and Invertebrates Living in the Vicinity of Energized and Unenergized Submarine Power Cables and Natural Sea Floor off Southern California, USA

Table 2

Effects of cable state (energized or unenergized), side of cable surveyed (west or east) nested in cable state, stratum groups (1–4), and year (2012–2014) on fish density tested using a generalized linear model (normal distribution, identity link) (). Densities were -transformed. Cable state is energized or unenergized. Stratum groups are discussed under Results. indicates statistical significance.
