  • 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. Michael Fahay 241 Sabino Road West Bath, Maine 04530 U.S.A. vi Acknowledgements I greatly appreciate the help provided by a number of very knowledgeable friends and colleagues dur- ing the preparation of this monograph. 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.

  • 126-1^2 on SOME INTERESTING and NEW RECORDS of MARINE FISHES from INDIA* Central Marine F
    i. Mar. biol Ass. tndia, 1968, 10 (1): 126-1^2 ON SOME INTERESTING AND NEW RECORDS OF MARINE FISHES FROM INDIA* By V. SRIRAMACHANDRA MURTY Central Marine Fisheries Research Institute, Mandapam Camp WHILE examining the fish landings by shore seines and trawl nets at various fishing centres along the Palk Bay and Gulf of Mannar in the vicinity of Mandapam the author came across several specimens of Drepane longimana (Bloch and Schneider) which is little known and Drepane punctata (Linnaeus) which was recognised as the only valid species of the genus Drepane, A study of these specimens has shown that these two species are distinct as shown by some authors (vide Text). A brief com­ parative account of these two species is given in this paper, along with a few remarks and key to distinguish the two species. The author has also been able to collect specimens of Platycephalus isacanthus Cuvier from the above catches, and a single specimen of Stethojulis interrupta (Bleeker) from the inshore waters of Gulf of Mannar caught in dragnet, whose occurrence, in Indian seas, is so far not known. Brief descriptions of these two species are also given in this paper. Family; DREPANIDAE Drepane longimana (Bloch and Schneider) This species was first described by its authors from Tranquebar. Cuvier and Valenciennes (1831) studied the specimens of the genus Drepane, both morphologi­ cally and anatomically and distinguished the two species D. longimana (Bloch and Schneider) and D. punctata (Linnaeus). Cantor (1850) also recognised the two species as valid. But subsequently Gunther (1860), Bleeker (1877) and Day (1878) recognised D.

The quadrato-mandibularis muscle lying behind the pterygoideus, with the nerve between them, is very much reduced and would appear to represent .the pars posterior only of the plagiostome muscle.

BAUN Abstract Sardines (Clupeidae) make up a substantial proportion of the fish catch across the Philippines and consequently are the most accessible source of animal protein for millions of Filipinos. Further, this fishery is an economic engine providing thousands of jobs and generating revenue at the individual, municipal, and national levels. Ecologically, sardines are basally positioned in a food web that supports pelagic tuna and mackerel, as well as numerous sea birds and marine mammals. Philippine sardine biodiversity is among the highest in the world and includes the only known freshwater sardine species.

    Syst Parasitol (2017) 94:443–462 DOI 10.1007/s11230-017-9717-5 Three members of Opisthomonorcheides Parukhin, 1966 (Digenea: Monorchiidae) from carangid fishes (Perciformes) from Indonesia, with a review of the genus Rodney A. Bray . Harry W. Palm . Scott C. Cutmore . Thomas H. Cribb Received: 28 November 2016 / Accepted: 10 March 2017 / Published online: 23 March 2017 Ó The Author(s) 2017. This article is an open access publication Abstract Three species of Opisthomonorcheides extending its range throughout the Indian Ocean into Parukhin, 1966 are reported for the first time from the south-western Pacific. All three species possess a Indonesian waters: O. pampi (Wang, 1982) Liu, Peng, genital atrium that is long, sometimes very long, and a Gao, Fu, Wu, Lu, Gao & Xiao, 2010 and O. ovacutus genital pore that is located in the forebody. This (Mamaev, 1970) Machida, 2011 from Parastromateus validates the interpretation that the original descrip- niger (Bloch), and O. decapteri Parukhin, 1966 from tion was erroneous in reporting the genital pore in the Atule mate (Cuvier). Both O. pampi and O. ovacutus hindbody, well posterior to the ventral sucker. These can now be considered widespread in the Indo-Pacific observations verify the synonymy of Retrac- region, with earlier records of these species being from tomonorchis Madhavi, 1977 with Opisthomonorchei- Fujian Province, China and Penang, Malaysia, respec- des. A major discrepancy between the species of tively. We redescribe O. decapteri from one of its Opisthomonorcheides is that some are described with original hosts, Atule mate, off New Caledonia, and the uterus entering the terminal organ laterally and report this species from Jakarta Bay, Indonesia, some with it entering terminally; this feature needs further analysis.

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences.

  • Zoogeography of Digenetic Trematodes from West African Marine Fishes1
    192 PROCEEDINGS OF THE HELMINTHOLOGICAL SOCIETY Zoogeography of Digenetic Trematodes from West African Marine Fishes1 JACOB H. FISCHTHAL Department of Biological Sciences, State University of New York at Binghamton, Binghamton, New York 13901. ABSTRACT: Of the 107 species of trematodes found in West African (Mauritania to Gabon) marine fishes, 100 are allocated to 64 genera in 24 families while seven are immature didymozoids. Many of these genera are located in most of the world's seas with the exception of the polar seas; only five are en- demic to West Africa. The data for the 41 species known from West Africa and elsewhere, and those morphologically closest to the 55 endemic species, indicate that they are very widely distributed, particularly in the Western and North Atlantic, and Mediterranean. Historical and present- day events concerning physical and biological environmental factors and their effects on actual and po- tential hosts as well as on life cycle stages of the trematodes have resulted in the geographical distribution reported. The distribution of marine fishes has been emphasized to explain in part the trematode distribu- tion. Studies on the geographical distribution of (Gulf of Guinea from 5° S to 15° N) and digenetic trematodes of marine fishes in various warm temperate Mauritania have been pre- seas have been presented by Manter (1955, sented by Ekman (1953), Buchanan (1958), 1963, 1967), Szidat (1961), and Lebedev Longhurst (1962), and Ingham (1970).

The digenetic trematodes Of the 107 species of trematodes found in of West African marine fishes (mainly shore West African fishes, 100 are allocated to 64 and shelf inhabitants) have been reported by genera in 24 families while seven are immature Dollfus (1929, 1937a, b, 1946, 1951, 1960), didymozoids of unknown generic status (Ap- Dollfus and Capron (1958), Thomas (1959, pendix I).
