In contrast to Heagney et al. (2007)’s methodology, we did not cap deployment durations at 45 min,
a value conventionally used in demersal baited remote underwater video systems studies (Watson
et al., 2010). From our results, the highest rate of time of Max N occurred between 60 and 90 min
(37%). Moreover, for the majority of our species (57%), Max N occurred after 45 min and some species
were only ever observed after 90 min (Strongylura leiura and Grammatorcynus bicarinatus). In contrast
to the high fish densities observed on the seabed, animal numbers in the pelagic zone are low, and as
such, it is not immediately clear that similar deployment duration in the pelagic would yield sufficient
power to detect discrepancies in spatial or temporal patterns detected in the demersal over such
time periods. It is likely that further sampling in Heagney’s study (Heagney et al., 2007), would have
revealed higher abundances of more slow-swimming and/or rare species.
