This study examined growth performance and osmoregulation in juvenile wolf eel (Anarrhichthys ocellatus) held in a series of dilute salinities (30, 14, 9, and 6 ‰) over an 8-week trial. Members of wolf fish family Anarhichadidae have emerged as potential cold-water marine aquaculture species. Identification was confirmed by the large rounded head and snout, large upturned mouth, and purple-gray color with numerous round spots around the eye and posteriorly on the head and body. " The water temperature at the bottom (site of observation) was 12.8° C. The wolf-eel was photographed at a depth of 70 ft (21.3 m) at 1100 hr with an Olympus C-5060 Wide Zoom digital camera off the dive boat " Dale's Panga. This locality is approximately 100 km southeast of Imperial Beach, California. The photographs represent the first record of a wolf-eel in Baja Californian waters and a new southern limit for the species.
On 26 November 2005, a wolf-eel was photographed by Sean Dyer while SCUBA diving off the Pacific coast of Baja California, Mexico, on Escondido Reef near La Bufadora (approx. Previously, Barnhart (1936) noted it to be " one of our most remarkable fishes: feeding chiefly on sea-urchins and sand dollars " and gave Redondo as the southern limit Hubbs and Barnhart (1944) extended this to La Jolla Submarine Canyon, San Diego County. " The southern limit for the species is off Imperial Beach, San Diego County, but it is not common south of Point Conception (Fitch and Lavenberg 1971). " The original two specimens were taken from " the Bay of San Francisco. The species is one of the early fishes described from California (Ayres 1855a and b) and was characterized as, " In color perhaps no more beautiful fish than this has yet been found in our waters. Records from the Sea of Japan (Miller and Lea 1972 Eschmeyer and Herald 1983) are not valid and were most likely based on Anarhichas orientalis Pallas, 1814. 2002) and occurs from the intertidal zone (Miller and Lea 1972) to the offshore shelf, up to 244 m depth (CAS 19447 see Table 1 for abbreviations). The wolf-eel (Anarrhichthys ocellatus Ayres, 1855) is an elongate, benthic perciform that inhabits the temperate North Pacific from the southeastern Bering Sea and eastern Aleutian Islands to southern California (Mecklenburg et al.
