Based on 27 replicate deployments of BUCs at 100m depth in the northern North Sea, in rank order of abundance, hagfish (Myxine glutinosa), flatfish mainly dabs (Limanda limanda), whiting (Merlangius merlangus) and haddock (Melanogramus aeglefinus) were observed consistently at baits. Higher maximum numbers (N max) occurred during daytime in all species with the most significant effect in flatfish, 18 in daytime and 5 at night-time. Bottom current had no significant effect on numbers of whiting, flatfish or haddock. The N max of hagfish was strongly related to current speed in a non-linear way with an increase in numbers up to 10cms−1 and then decrease in N max at higher water speeds. Understanding and accounting for such species-specific influences is important in the design of long term monitoring surveys using baited cameras.
