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".

Jellynose fish Jellynose fish The jellynose fishes or tadpole fishes are the small order Ateleopodiformes. This group of ray-finned fish is monotypic, containing a single family Ateleopodidae. It has about a dozen species in four genera, but these enigmatic fishes are in need of taxonomic revision. The scientific name means ""Ateleopus"-shaped", from "Ateleopus" (the type genus) + the standard fish order suffix "-formes". It ultimately derives from Ancient Greek "atelís" (ἆτελής, "imperfect") + "pús" (πούς, "foot") + Latin "forma" ("external form"), the Greek part in reference to the reduced pectoral and ventral fins of the jellynoses. Jellynoses are deep-water, bottom-dwelling, marine fishes.
