Taxonomy and Ecology of the Deep-Pelagic Fish Family Melamphaidae, with Emphasis on Interactions with a Mid- Ocean Ridge System TAXONOMY AND ECOLOGY OF THE DEEP-PELAGIC FISH FAMILY MELAMPHAIDAE, WITH EMPHASIS ON INTERACTIONS WITH A MID- OCEAN RIDGE SYSTEM by Kyle Allen Bartow A Dissertation Submitted to the Faculty of The Charles E. Schmidt College of Science in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy Florida Atlantic University Boca Raton, FL December 2010 Copyright by Kyle Bartow 2010 ii ACKNOWLEDGEMENTS The research in this dissertation is due to funding from Tracey Sutton from the U.S. National Science Foundation Ocean Sciences Division – Biological Oceanography Program (OCE 0623568). Funding for travel and tuition were received for various parts of this project from Florida Atlantic University and Virginia Institute of Marine Science. I am grateful to the crew of the RV G.O. Sars, MAR-ECO and the staff of the Bergen Museum for the collection and curation of samples. I would also like to thank the U.S. National Museum of Natural History - Division of Fishes for allowing me into their enormous collection of melamphaid fishes and being so flexible and accommodating during the largest blizzard I've ever been in. The final entity that I would like to thank is MAR-ECO, through whose association I have been afforded many of these opportunities. I would like to thank Tracey Sutton for initially believing in me and my interest in deep-sea fish and research. Tracey not only offered me a place to fulfill my goals, but offered much support and encouragement during many of my trials and tribulations. Thanks are also due to the members of my advisory committee: Edie Widder, Jon Moore, C. Edward Proffitt and Brian Lapointe. Their edits and input into my project allowed it to mature into the final product that it is today. At Florida Atlantic University I would like to thank Geri Mayer, Jenny Govender and Becky Dixon. Without their help, it would have been impossible to get through the everyday challenges of being a graduate student and to find the answers to all my school related questions and issues. iv Finally, I would like to thank all the members of my family. My parents Allen and Kozie Bartow, Ginny Hustvedt and Dan Oberholzer not only for their love and support but also showing me that what I am doing is both important and interesting. The Knight family (Tim, Kathleen, Kristin, Kaitlin, Jared and Jordan) deserves many thanks as well. They were not only my friends, but like a second family to me growing up and played a major role in the person I am today. I also thank my wife, Jen, deserves a lot of my gratitude, not only for all the love she's shown, but for dealing with my weirdness, meltdowns and the extreme amount of input and advice she has given to this project. And I thank our friends Allyson and Johnnie Schumacher, Sara Fitzgerald and Joey Johnson for keeping me grounded, sane and keeping my life balanced and preventing grad student burnout. ABSTRACT Author: Kyle Bartow Title: Taxonomy and Ecology of the Deep-Pelagic Fish Family Melamphaidae, with Emphasis on Interactions with a Mid-Ocean Ridge System Institution: Florida Atlantic University Dissertation Advisor: Dr. Tracey Sutton Degree: Doctor of Philosophy Year: 2010 Much of the world’s oceans lie below a depth of 200 meters, but very little is known about the creatures that inhabit these deep-sea environments. The deep-sea fish family Melamphaidae (Stephanoberyciformes) is one such example of an understudied group of fishes. Samples from the MAR-ECO (www.mar-eco.no) project represent one of the largest melamphaid collections, providing an ideal opportunity to gain information on this important, but understudied, family of fishes. The key to the family presented here is the first updated, comprehensive key since those produced by Ebeling and Weed (1963) and Keene (1987). Samples from the 2004 MAR-ECO cruise and the U.S. National Museum of Natural History provided an opportunity to review two possible new species, the Scopelogadus mizolepis subspecies, and a Poromitra crassiceps species complex. Results show that Scopeloberyx americanus and Melamphaes indicoides are new species, while the two subspecies of Scopelogadus mizolepis are most likely only one species and the Poromitra crassiceps complex is actually several different species of Poromitra. vi Data collected from the MAR-ECO cruise provided an opportunity to study the distribution, reproductive characteristics and trophic ecology of the family Melamphaidae along the Mid-Atlantic Ridge (MAR). Cluster analysis showed that there are five distinct groups of melamphaid fishes along the MAR. This analysis also supported the initial observation that the melamphaid assemblage changes between the northern and southern edges of an anti-cyclonic anomaly that could be indicative of a warm-core ring. Analysis of the reproductive characteristics of the melamphaid assemblage revealed that many of the female fishes have a high gonadosomatic index (GSI) consistent with values found for other species of deep-sea fishes during their spawning seasons. This may indicate that melamphaids use this ridge as a spawning ground. Diets of the melamphaid fishes were composed primarily of ostracods, amphipods, copepods and euphausiids. Scopelogadus was the only genus shown to have a high percent of gelatinous prey in their digestive system, while Melamphaes had the highest concentration of chaetognaths. This work presents data on the ecology and taxonomy of the family Melamphaidae and provides a strong base for any future work on this biomass-dominant family of fishes. vii TAXONOMY AND ECOLOGY OF THE DEEP-PELAGIC FISH FAMILY MELAMPHAIDAE, WITH EMPHASIS ON INTERACTIONS WITH A MID- OCEAN RIDGE SYSTEM LIST OF TABLES .......................................................................................................... x LIST OF FIGURES ....................................................................................................... xiii CHAPTER 1.

  • Spatial and Temporal Distribution of the Demersal Fish Fauna in a Baltic Archipelago As Estimated by SCUBA Census
    MARINE ECOLOGY - PROGRESS SERIES Vol. 23: 3143, 1985 Published April 25 Mar. Ecol. hog. Ser. 1 l Spatial and temporal distribution of the demersal fish fauna in a Baltic archipelago as estimated by SCUBA census B.-0. Jansson, G. Aneer & S. Nellbring Asko Laboratory, Institute of Marine Ecology, University of Stockholm, S-106 91 Stockholm, Sweden ABSTRACT: A quantitative investigation of the demersal fish fauna of a 160 km2 archipelago area in the northern Baltic proper was carried out by SCUBA census technique. Thirty-four stations covering seaweed areas, shallow soft bottoms with seagrass and pond weeds, and deeper, naked soft bottoms down to a depth of 21 m were visited at all seasons. The results are compared with those obtained by traditional gill-net fishing. The dominating species are the gobiids (particularly Pornatoschistus rninutus) which make up 75 % of the total fish fauna but only 8.4 % of the total biomass. Zoarces viviparus, Cottus gobio and Platichtys flesus are common elements, with P. flesus constituting more than half of the biomass. Low abundance of all species except Z. viviparus is found in March-April, gobies having a maximum in September-October and P. flesus in November. Spatially, P. rninutus shows the widest vertical range being about equally distributed between surface and 20 m depth. C. gobio aggregates in the upper 10 m. The Mytilus bottoms and the deeper soft bottoms are the most populated areas. The former is characterized by Gobius niger, Z. viviparus and Pholis gunnellus which use the shelter offered by the numerous boulders and stones. The latter is totally dominated by 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.

  • Grade 3 Unit 2 Overview Open Ocean Habitats Introduction
    G3 U2 OVR GRADE 3 UNIT 2 OVERVIEW Open Ocean Habitats Introduction The open ocean has always played a vital role in the culture, subsistence, and economic well-being of Hawai‘i’s inhabitants. The Hawaiian Islands lie in the Pacifi c Ocean, a body of water covering more than one-third of the Earth’s surface. In the following four lessons, students learn about open ocean habitats, from the ocean’s lighter surface to the darker bottom fl oor thousands of feet below the surface. Although organisms are scarce in the deep sea, there is a large diversity of organisms in addition to bottom fi sh such as polycheate worms, crustaceans, and bivalve mollusks. They come to realize that few things in the open ocean have adapted to cope with the increased pressure from the weight of the water column at that depth, in complete darkness and frigid temperatures. Students fi nd out, through instruction, presentations, and website research, that the vast open ocean is divided into zones. The pelagic zone consists of the open ocean habitat that begins at the edge of the continental shelf and extends from the surface to the ocean bottom. This zone is further sub-divided into the photic (sunlight) and disphotic (twilight) zones where most ocean organisms live. Below these two sub-zones is the aphotic (darkness) zone. In this unit, students learn about each of the ocean zones, and identify and note animals living in each zone. They also research and keep records of the evolutionary physical features and functions that animals they study have acquired to survive in harsh open ocean habitats.

Zacharia Demersal Fisheries Division ICAR -Central Marine Fisheries Research Institute, Kochi ased on their vertical distribution, fishes are broadly classified as pelagic or demersal. Species those are distributed from the seafloor to a 5 m depth above, are called demersal and those distributed from a depth of 5 m above the seafloor to the sea surface are called pelagic. The term demersal originates from the Latin word demergere, which means to sink. The demersal fish resources include the elasmobranchs, major perches, catfishes, threadfin breams, silverbellies, sciaenids, lizardfishes, pomfrets, bulls eye, flatfishes, goatfish and white fish.

Corresponding author: Peng Xu ([email protected]) http://zoobank.org/B5BBA46C-7FC5-44C3-B9CE-19F8E93FAA1C ABSTRACT. The whole mitochondrial genome of Lateolabrax maculatus (Cuvier, 1828) was used to investigate the reasons for the observed patterns of genetic differentiation among 12 populations in northern and southern China. The haplotype diversity and nucleotide diversity of L. maculatus were 0.998 and 0.00169, respectively. Pairwise FST values between popula- tions ranged from 0.001 to 0.429, correlating positively with geographic distance. Genetic structure analysis and haplotype network analysis indicated that these populations were split into two groups, in agreement with geographic segregation and environment. Tajima’s D values, Fu’s Fs tests and Bayesian skyline plot (BSP) indicated that a demographic expansion event may have occurred in the history of L. maculatus. Through selection pressure analysis, we found evidence of significant negative selection at the ATP6, ND3, Cytb, COX3, COX2 and COX1 genes.
