A rare bathypelagic fish (Family Melanostomiatidae) from the eastern Atlantic Ocean
Helgoländer wissenschaftliche Meeresuntersuchungen volume 18, pages 61–68 (1968)
Abstract
A fish, 218 mm standard length, member of the melanostomiatid genusPachystomias and tentatively identified asPachystomias (?)microdon (Günther 1878) is figured and thoroughly described. The relation to other members of the genus (only 5 specimens of 2 species are known up to now) is discussed. The fish was caught on “Meteor” station no. 4/66 (position 43° 10′ N. lat. and 13° 51′ W. long.) by the Isaac-Kidd-Midwater-Trawl on March 1, 1966. The towing speed was 5 n.m./h. at 3.500 m. wire out; from this the maximum fishing depth is estimated to have been 900 to 1000 meters.
