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
Pelagic fish stacks with a range of different spacings. A further complication for fish with bodies that are rounded in cross-section is that the mirrors would be ineffective if laid flat on the skin, as they would fail to reflect horizontally. The overall mirror effect is achieved with many small reflectors, all oriented vertically. Though the number of species is limited, epipelagic fishes are abundant. What they lack in diversity they make up in numbers. Forage fish occur in huge numbers, and large fish that prey on them are often sought after as premier food fish. As a group, epipelagic fishes form
