THOMAS AND SANDHYA SUKUMARAN ICAR-Central Marine Fisheries Research Institute, P. B. No. 1603, Ernakulam North P. O. Kochi - 682 018, Kerala, India e-mail: [email protected] ABSTRACT A new species of Harpadon Lesueur, 1825 captured from the continental slope area 19° 53’ N - 69° 23’E (north-eastern Arabian Sea) is described. The species Harpadon nudus sp. nov. was identified possessing a prominent trilobed caudal fin and a wide mouth with strong fang like barbed teeth and has been distinguished from its congeners by the following combination of characters: slender, completely scaleless body with very short pectoral (8.6 - 13.8% SL) and pelvic (16.4 - 21.6% SL) fins, large eyes (9.1 - 15.1% HL) with narrow inter-orbital width (15% of HL) and single pair of nares, situated close to the tip of the narrow snout. Morphologically it differs from the partially scaled species such as Harpadon nehereus in having very short pectoral fins not reaching up to its dorsal fin, single pair of nares and a pointed snout in dorsal view. It can be distinguished from Harpadon microchir by its greater head length of 22 - 26% SL; absence of scales at the base of the adipose fin and on the lateral line as well as the dorsal fin count of 12 rays. It is differentiated from Harpadon mortenseni by its lower lateral line pores count (40 - 43), higher number of branchiostegals (17 to 20), absence of scales on the lateral line or caudal peduncle and absence of vomerine teeth.

  • Early Stages of Fishes in the Western North Atlantic Ocean Volume
    ISBN 0-9689167-4-x Early Stages of Fishes in the Western North Atlantic Ocean (Davis Strait, Southern Greenland and Flemish Cap to Cape Hatteras) Volume One Acipenseriformes through Syngnathiformes Michael P. Fahay ii Early Stages of Fishes in the Western North Atlantic Ocean iii Dedication This monograph is dedicated to those highly skilled larval fish illustrators whose talents and efforts have greatly facilitated the study of fish ontogeny. The works of many of those fine illustrators grace these pages. iv Early Stages of Fishes in the Western North Atlantic Ocean v Preface The contents of this monograph are a revision and update of an earlier atlas describing the eggs and larvae of western Atlantic marine fishes occurring between the Scotian Shelf and Cape Hatteras, North Carolina (Fahay, 1983). The three-fold increase in the total num- ber of species covered in the current compilation is the result of both a larger study area and a recent increase in published ontogenetic studies of fishes by many authors and students of the morphology of early stages of marine fishes. It is a tribute to the efforts of those authors that the ontogeny of greater than 70% of species known from the western North Atlantic Ocean is now well described.

Jon Hare undertook a painstakingly critical review of the entire monograph, corrected omissions, inconsistencies, and errors of fact, and made suggestions which markedly improved its organization and presentation.

The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences.

Biota Neotropica. 19(1): e20170432. http://dx.doi.org/10.1590/1676-0611-BN-2017-0432 Abstract: Demersal fishery resources are abundant on continental shelves, on the tropical and subtropical coasts, making up a significant part of the marine environment. Marine demersal fishery resources are captured by various fishing methods, often unsustainably, which has led to the depletion of their stocks. In order to inventory the marine demersal ichthyofauna on the Southern Brazilian coast, as well as their conservation status and distribution, this study analyzed the composition and frequency of occurrence of fish captured by pair trawling in 117 fishery fleet landings based in the State of São Paulo between 2005 and 2012.

Abstract The otoliths described in this study from the Late Eocene to Early Oligocene (biozone P18) of the Kishima Formation near Karatsu, Saga Prefecture, represent the earliest record of fossil otoliths from Japan and in fact the entire Northwest Pacific. They were obtained from outcrops along the Shimohirano River. A total of 13 otolith-based teleost taxa are recognized, 11 of which being identifiable to species level and new to science and five new genera. The new otolith-based genera are: Nishiberyx n. gen. (Berycidae), Sagaberyx n. gen. (Berycoidei family indet.), Namicauda n. gen. (Polymixiidae), Ortugobius n. gen. (tentatively placed in Gobiidae) and Cornusolea n. gen.

Otolith assemblages have rarely been studied across the K-Pg boundary. The late Maastrichtian Kemp Clay of northeastern Texas and the Fox Hills Formation of North Dakota, and the early Danian Clayton Formation of Arkansas therefore offer new insights into how teleost fishes managed across the K-Pg boundary as reconstructed from their otoliths. The Kemp Clay contains 25 species, with 6 new species and 2 in open nomenclature and the Fox Hills Formation contains 4 species including 1 new species. The two otolith associations constitute the Western Interior Seaway (WIS) community.
