  • A New Pipefish from Queensland
    A NEW PIPEFISH FROM QUEENSLAND. By A. FRASER-BRUNNER, F.Z.S., British Museum (Natural History), and G. P. WHITLEY, F.R.Z.S., Curator of Fishes, Australian Museum. (Figures 1-2.) When drawing some types of Australian fishes in the British Museum, the senior author found a specimen of a Queensland Pipefish which did not agree with Gunther's , type (from Suez) of the species (Acentronura tentaculata) with which it had been previously ~ssociated .(Duncker, 1915; McCulloch and Whitley, 1925; Dollfus and Petit, 1938). He prepared a description and figure of the specimen, and sent them to the junior author, who studied the fish in relation to the literature and made taxonomic comparisons with its congeners. The specimen is considered to belong to a new species. Family SYNGNATHIDAE. Genus ACENTRONURA Kaup, 1853. Acentronura breviperula, sp. novo (Figure 1.) Length of head contained 2!! times in head plus trunk. Snout equal to diameter of eye, half as long as postorbital part of head. Tail about 1~ times length of combined head and trunk. Thirteen body rings; 42 tail rings, the first seven of which form the brood-pouch. Dorsal fin on 4!! rings, two of which are caudal. Dorsal rays 16; pectoral 15.

  • 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.

The fossils were collected in the Middle Miocene (Sarmatian) beds of the Coprolitic Horizon in the Tunjice Hills, Slovenia. They belong to a new genus and species Hippotropiscis frenki, which was similar to the extant representatives of Acentronura, Amphelikturus, Idiotropiscis, and Kyonemichthys genera. Hippotropiscis frenki lived among seagrasses and macroalgae and probably also on a mud and silt bottom in the temperate shallow coastal waters of the western part of the Central Paratethys Sea. The high coronet on the head, the ridge system and the high angle at which the head is angled ventrad indicate that Hippotropiscis is most related to Idiotropiscis and Hippocampus (seahorses) and probably separated from the main seahorse lineage later than Idiotropiscis. © 2012 Elsevier Masson SAS.

    State of research of the Osteichthyes fish related to coral reefs in the Honduran Caribbean with catalogued records Estado del conocimiento de los peces osteíctios asociados a los arrecifes de coral en el Caribe de Honduras, con registros catalogados Anarda Isabel Salgado Ordoñez1, Julio Enrique Mérida Colindres1* & Gustavo Adolfo Cruz1 ABSTRACT Research on Honduran coral reef fish has been isolated and scattered. A list of fish species related to coral reefs was consolidated to establish a compiled database with updated taxonomy. The study was conducted between October 2017 and December 2018. Using primary and secondary sources, all potential species in the Western Atlantic were considered, and their actual presence was confirmed using catalogued records published in peer-reviewed journals that included Honduras. In addition, the specimens kept in the Museum of Natural History of Universidad Nacional Autónoma de Honduras were added. Once the list was consolidated, the taxonomic status of each species was updated based on recent literature. A total of 159 species and 76 genera were registered in 32 families. The family with the most species was Labrisomidae with 27 species (17%). Five families had more than five 5 genera registered, while four 4 were represented by more than 16 species, which is equivalent to 42% genera and 51% species. Gobiidae was represented by 10 genera (13%) and 21 species (13%), of which two 2 were endemic: Tigrigobius rubrigenis and Elacatinus lobeli. In turn, Grammatidae was represented by one endemic species Lipogramma idabeli (1.8%). The species Diodon holocanthus and Sphoeroides testudineus represent the first catalogued records for Honduras.

  • An Examination of the Population Dynamics of Syngnathid Fishes Within Tampa Bay, Florida, USA
    Current Zoology 56 (1): 118−133, 2010 An examination of the population dynamics of syngnathid fishes within Tampa Bay, Florida, USA Heather D. MASONJONES1*, Emily ROSE1,2, Lori Benson McRAE1, Danielle L. DIXSON1,3 1 Biology Department, University of Tampa, Tampa, FL 33606, USA 2 Biology Department, Texas A & M University, College Station, TX 77843, USA 3 School of Marine and Tropical Biology, James Cook University, Townsville QLD 4811, AU Abstract Seagrass ecosystems worldwide have been declining, leading to a decrease in associated fish populations, especially those with low mobility such as syngnathids (pipefish and seahorses). This two-year pilot study investigated seasonal patterns in density, growth, site fidelity, and population dynamics of Tampa Bay (FL) syngnathid fishes at a site adjacent to two marinas un- der construction. Using a modified mark-recapture technique, fish were collected periodically from three closely located sites that varied in seagrass species (Thalassia spp., Syringodium spp., and mixed-grass sites) and their distance from open water, but had consistent physical/chemical environmental characteristics. Fish were marked, photographed for body size and gender measure- ments, and released the same day at the capture site. Of the 5695 individuals surveyed, 49 individuals were recaptured, indicating a large, flexible population. Population density peaks were observed in July of both years, with low densities in late winter and late summer. Spatially, syngnathid densities were highest closest to the mouth of the bay and lowest near the shoreline. Seven species of syngnathid fishes were observed, and species-specific patterns of seagrass use emerged during the study. However, only two species, Syngnathus scovelli and Hippocampus zosterae, were observed at high frequencies.
