Ichthyofauna of Corner Mountains and New England Seamounts

Kukuyev E.I.

This work is a result of study of the deep-water fish collected in 1976-1978 in the regions of the Sloping Rise and New England Sea-Mounts. The tows were made mostly with a pelagic trawl near the top of the ridges and along the slopes between 600 and 1110 m. The collection comprises epipelagic, mesopelagic, bathyal and bathyal-pelagic species of fish. Some species of the benthic ichthyofauna were collected with bottom trawls. The rich collection of fish of the Sloping Rise has been deposited for keeping in the Zoological Museum of the Moscow State University. The author owes thanks to many people for their assistance. Thanks are due to Verenko V. for his substantial help in collecting of the fish. Further acknowledgment goes to Parin N. V. for supervising; Bekker V. E.. for access to his clues for identification of the myctophids, still unpublished; Verigina I. A. for continuous assistance when working over the collection. I thank Pokhilskaya G. N. for identification of the specimens in the genus Eustomidias and Aristostomias, Karmovskaya E. S. for identification of eels in the Nemichthioidei suborder. Sazonov Y. I. for identification of the specimens of the Platytroctidae family and Mikhaylin S V. for identification of trichiuroid fish.

The region of exploration (oceanographic description)

The Sloping Rise is situated south of the Grand Banks of Newfoundland near the eastern edge of the Sohm Abyssal Plain. In the east it is continuous with the west wing of the Mid-Atlantic Ridge, in the west it adjoins the Bermuda Rise and extends within the coordinates 33o 40/ - 36o N and 47o - 53o W. The Rise has a volcanic origin. It towers over the gently sloping base situated at depths of 3500 - 4000 m (Ilyin, 1976). The distance between the top of the mounts and water surface is 660 -1900 m. The New England range of sea-mounts extends along the north-eastern edge of Bermuda sea-mounts from north-west to south-east from 34o to 38o N. The mounts are 2000-3000 m high. The biggest ones among them are mounts Kelvin, San-Pablo, Rechops, Michael, Nashwill with minimum depths over their tops between 900 and1600 m (Litvin, 1980). The hydrological structure in the region of the Sloping Rise is of the subtropical type. Superficial subtropical water masses (water temperature. 15-20o to 25-28o C) occupy the upper 300 –500 m layer. The intermediate northern Atlantic water mass lies at depths of 500 -1500 m. Average temperature is relatively stable. It is 7.0; 3.9; 2.9o C at the respective depths of 1000, 2000 and 3000m. Gulf Stream currents, meanders and discontinuity of bottom relief influence the water dynamics in the region. The west regions of the Sloping Rise are the most exposed to the influence of Gulf Stream waters. The process of driving the water masses to the northeast, east and southeast occurs in a system of superficial currents in the region. The greater the depth (300 - 500 m and so on), the more the direction of the water masses changes towards south–west.

Annotated list of fishes

The list comprises about 1800 specimens, including 192 fish species of 60 families. The data is represented in the following order: species name, number of specimens, range of length (in mm) from minimum to maximum given within brackets. The total length of sharks, eels and macrurids is marked as TL; SL means standard length for other fish. Following the range of lengths is the name of the Research Vessel during whoose cruise the fishes were collected (A – “Atlant”, B – “Bakhchisaray”, C – “Coryphena”, E – “Eureka”) and number of trawl. The data of depths and regions of trawling are summarized in the Table. Short descriptions are given for the unusual and uncommon fishes in cases where the fish could not be identified with certainty. Abbreviations given in the descriptions are: C – head length c -- snout length o – eye diameter ao – distance between eyes b – barbel length I D – dorsal fin base I A – anal fin base aD – interdorsal space aA – interanal space aV – interventral

FAM. HEXANCHIDAE Hexanchus griseus (Bonnaterre). This species and the next one were identified at sea (by Verenko V. I) since they did not occur in collections.

According to the principal measurements of fish body (% TL) it corresponds to the species description by Jordan (1898): Length from tip of the snout to line connecting the front tips of nostrils is 10, 4; ------to mouth is 9.0; ------to the first gill opening is 18. 6; ------to the second gill opening is 23. 0; ------to the fifth gill opening is 25.5; - preorbital length is 12.0; - pectoral fin base is 26.0; - pelvic fin base is 48.5; - first dorsal fin base is 34.3; - second dorsal fin base is 62.0; - base of caudal fin’s upper lobe is 72.0; - length between first and fifth gill opening 6.8; - length of first gill opening is 3.9 - length of third gill opening is 4.1; length of fifth gill opening is 4.1; - eye length is 0.7; - first dorsal fin base is 6.9; - second dorsal fin base is 6.4; - anal fin base is 9.8; - length of pectoral fin is 4.7; - length of pelvic fin is 11;. - length of caudal fin’s upper lobe is 30.1; The studied specimen differs from the holotype by the position of the first dorsal fin, (which is placed distinctly behind the posterior tip of pectoral fin), bigger pectoventral length and shorter length of upper lobe of the caudal fin.. However, these distinctions might be caused by age differences. The species has been reported from the offshore regions of Japan (Jordan, 1898; Jordan & Snyder, 1904; Fowler, 1941), South Australia (Zeitz, 1908), South Africa (Bass et al., 1976), France and Ghana (Quero, 1978).
