Redbanded rockfish In 1995, 280 tons were caught by longline off British Columbia. Often, though, this fish is taken as bycatch during trawling operations targeting other species, such as the yelloweye rockfish ("S. ruberrimus") and halibut ("Hippoglossus stenolepis"). Bycatch of this species in trawls off the coast of British Columbia well exceeded 1,000 tons in 1992. It has dropped below 300 tons per year since then due to better monitoring. This fish is host to a number of parasitic copepods, including "Chondracanthus pinguis", "C. triventricosus", "Clavella parva", "Colobomatus kyphosus", "Naobranchia occidentalis", "Peniculus asinus", and "Neobrachiella robusta". Redbanded rockfish Sebastes babcocki is a
Demersal fish and invertebrates that pass overhead. Some species have a worm-shaped lure growing out of the floor of the mouth, which they wiggle to attract prey. Stargazers are venomous and can deliver electric shocks. They have been called "the meanest things in creation." Other examples of coastal demersal fish are cod, plaice, monkfish and sole. Deep water demersal fish occupy the benthic regions beyond the continental margins. On the continental slope, demersal fishes are common. They are more diverse than coastal demersal fish, since there is more habitat diversity. Further out are the abyssal plains. These flat, featureless regions occupy about
