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. -
MEESO Survey to the North Atlantic Ocean, 1-30 June 2021
MEESO survey to the North Atlantic Ocean, 1-30 June 2021 R/V “G.O. Sars”, surveying the North Atlantic Ocean mesopelagic sone during the light summer nights. Photo: Chris Lindemann. As part of the MEESO field campaign, the Norwegian Research Vessel, G. O. Sars, is sur- veying the mesopelagic ecosystem of the North-East Atlantic and the Norwegian Sea. The cruise started in Bergen, Norway, 1 June and ends there 30 June. Scientists from the University of Bergen and the Institute of Marine Research in Bergen, Nor- way, are using new technology, partly developed in MEESO, like non-graded trawls and un- derwater towed systems with optical sensors and broadband multifrequency acoustics to in- vestigate the mesopelagic ecosystem and map the biomass distribution of the mesopelagic community and its possible drivers. So far we have identified more than 90 species of fish and the diversity of crustaceans, gelati- nous plankton and cephalopods has proven to be high as well. A marked fall in diversity and the vertical extent of the mesopelagic deep scattering layers were observed as we moved from the Iceland Basin, south of Iceland and west of the Faroe Islands, into the Norwegian Sea.

On Turbulence Production by Swimming Marine Organisms in the Open Ocean and Coastal Waters
SEPTEMBER 2010 R O U S S E A U E T A L . 2107 On Turbulence Production by Swimming Marine Organisms in the Open Ocean and Coastal Waters SHANI ROUSSEAU,* ERIC KUNZE,RICHARD DEWEY,KEVIN BARTLETT, AND JOHN DOWER SEOS, University of Victoria, Victoria, British Columbia, Canada (Manuscript received 15 December 2009, in final form 24 April 2010) ABSTRACT Microstructure and acoustic profile time series were collected near Ocean Station P in the eastern subarctic North Pacific and in Saanich Inlet at the south end of Vancouver Island, British Columbia, Canada, to ex- amine production of turbulent dissipation by swimming marine organisms. At Ocean Station P, although a number of zooplankton species are large enough to generate turbulence with Reynolds numbers Re . 1000, biomass densities are typically less than 103 individuals per cubic meter (,0.01% by volume), and turbulent kinetic energy dissipation rates « were better correlated with 16-m vertical shear than acoustic backscatter layers. In Saanich Inlet, where krill densities are up to 104 individuals per cubic meter (0.1% by volume), no dramatic elevation of dissipation rates « was associated with dusk and dawn vertical migrations of the acoustic backscatter layer. Dissipation rates are a factor of 2 higher [h«i 5 1.4 3 1028 Wkg21, corresponding to buoyancy Re 5 h«i/(nN2) ; 140] in acoustic backscatter layers than in acoustically quiet waters, regardless of whether they are vertically migrating. The O(1 m) thick turbulence patches have vertical wavenumber spectra for microscale shear commensurate with the Nasmyth model turbulence spectrum. However, the turbulence bursts of O(1025 Wkg21) proposed to occur in such dense swarms appear to be rare. -
Olfactory Organs in the Deep Sea Hatchetfish <I>Sternoptyx
NOTES BULLETIN OF MARINE SCIENCE, 53(3): 1163-1167, 1993 OLFACTORY ORGANS IN THE DEEP SEA HATCHETFISH STERNOPTYX DIAPHANA (STOMIIFORMES, STERNOPTYCHIDAE) Ronald C. Baird and George Y. Jumper It has been estimated that more than 80% of the deep sea fish fauna living at depths greater than 1,000 m exhibit sexual dimorphism in the olfactory system (Marshall, 1967). The most common form of dimorphism involves development oflarge, complex olfactory receptors in males while in females the olfactory system is regressed or microsmatic. Marshall also notes that in contrast, mesopelagic fishes living at depths less than 1,000 m generally have well-developed olfactory systems in both sexes and sexual dimorphism is uncommon. Recently, sexual dimorphism was reported in the olfactory organs of two me- sopelagic sternoptychids Argyropelecus hemigymnus and Valenciennellus tri- punctulatus by Baird et aI., 1990. Unlike many of the deeper living fishesdescribed by Marshall (op. cit.) the olfactory systems in females of these species are relatively well developed. The potential advantages of chemical communication to mate location in deep- sea fishes have been explored by Jumper and Baird (1991) and the use of odor cues appears to greatly enhance mate location in A. hemigymnus. The nasal rosettes of the hatchetfish Sternoptyx diaphana do not exhibit di- morphism. More importantly, the nasal rosettes of both sexes in S. diaphana are much smaller in size, and considerably less complex in structure than in A. hemi- gymnus. In this article, we describe the external morphology of the olfactory organs in sexually mature individuals of S. diaphana, compare them to that found in A. -

Recycled Fish Sculpture (.PDF)
Recycled Fish Sculpture Name:__________ Fish: are a paraphyletic group of organisms that consist of all gill-bearing aquatic vertebrate animals that lack limbs with digits. At 32,000 species, fish exhibit greater species diversity than any other group of vertebrates. Sculpture: is three-dimensional artwork created by shaping or combining hard materials—typically stone such as marble—or metal, glass, or wood. Softer ("plastic") materials can also be used, such as clay, textiles, plastics, polymers and softer metals. They may be assembled such as by welding or gluing or by firing, molded or cast. Researched Photo Source: Alaskan Rainbow STEP ONE: CHOOSE one fish from the attached Fish Names list. Trout STEP TWO: RESEARCH on-line and complete the attached K/U Fish Research Sheet. STEP THREE: DRAW 3 conceptual sketches with colour pencil crayons of possible visual images that represent your researched fish. STEP FOUR: Once your fish designs are approved by the teacher, DRAW a representational outline of your fish on the 18 x24 and then add VALUE and COLOUR . CONSIDER: Individual shapes and forms for the various parts you will cut out of recycled pop aluminum cans (such as individual scales, gills, fins etc.) STEP FIVE: CUT OUT using scissors the various individual sections of your chosen fish from recycled pop aluminum cans. OVERLAY them on top of your 18 x 24 Representational Outline 18 x 24 Drawing representational drawing to judge the shape and size of each piece. STEP SIX: Once you have cut out all your shapes and forms, GLUE the various pieces together with a glue gun. -

E-mail: [email protected] Abstract Recent pelagic and benthic trawling activities over the Brazilian continental slope between 11° and 23°S captured nine species representing five genera of the stomiiform family Sternoptychidae. Among these, three species are new records for Brazilian waters: Sternoptyx pseudodiaphana, Argyripnus atlanticus, and Polyipnus sp. The known distributions of Argyropelecus aculeatus and Maurolicus stehmanni along the Brazilian coast are extended northward to 13°S and 16°S, respectively, while that of Sternoptyx diaphana is extended southward to 13°S. Argyropelecus hemigymnus, Argyropelecus sladeni, and Sternoptyx pseudobscura were rarely caught (n=2–16). -
