Mean bait removal times (±s.e., n = 4) and wet weight, C, N and gross energy (GE) consumption rates (±s.e., n = 4) calculated for the different baits. The removal time was the time between the lander arriving at the seafloor and the time when no more bait was visible on the bait plate. Consumption rates were calculated from the known wet weight, C, N and energy content of the baits (derived from the wet weight of the bait and C, N and GE content per unit wet weight) and the removal times. p-values from statistical tests are shown and treatments that differed significantly (p < 0.05) are shown in the significant multiple comparisons row.
