BONY FISHES 602 Bony Fishes
click for previous page BONY FISHES 602 Bony Fishes GENERAL REMARKS by K.E. Carpenter, Old Dominion University, Virginia, USA ony fishes constitute the bulk, by far, of both the diversity and total landings of marine organisms encoun- Btered in fisheries of the Western Central Atlantic.They are found in all macrofaunal marine and estuarine habitats and exhibit a lavish array of adaptations to these environments. This extreme diversity of form and taxa presents an exceptional challenge for identification. There are 30 orders and 269 families of bony fishes presented in this guide, representing all families known from the area. Each order and family presents a unique suite of taxonomic problems and relevant characters. The purpose of this preliminary section on technical terms and guide to orders and families is to serve as an introduction and initial identification guide to this taxonomic diversity. It should also serve as a general reference for those features most commonly used in identification of bony fishes throughout the remaining volumes. However, I cannot begin to introduce the many facets of fish biology relevant to understanding the diversity of fishes in a few pages. For this, the reader is directed to one of the several general texts on fish biology such as the ones by Bond (1996), Moyle and Cech (1996), and Helfman et al.(1997) listed below. A general introduction to the fisheries of bony fishes in this region is given in the introduction to these volumes. Taxonomic details relevant to a specific family are explained under each of the appropriate family sections. The classification of bony fishes continues to transform as our knowledge of their evolutionary relationships improves. -

With Text-figures 1-10 Chondracanthidae is a family of highly transformed cyclopoid copepods that are found exclusively on marine demersal fish. Although a complete life history of this family of copepods is still unknown, it seems, judging from the available infor mation of their larval development, that the parasites do not require an intermediate host. Both adult and larva are found in the oral-branchial cavity of the fish, attaching to the host tissue by their powerful, hook-like second antenna. Although a few species are known to live in the nasal cavity, they have not been found on the body surface or fins of the fish. The male is characteristically dwarf and attaches to the genital area of the female throughout its life. In many species, the transformed female has a pair of small processes on the posteroventral surface of the trunk just in front of the genital segment. The pigmy male holds on to one of these two processes by its transformed hook-like second antennae. -

The species are: Chondracanthus fnerluccii, Brachiel/a merluccii and Parabrachiella australis. The parasites importance as indicators of the affinities between hakes is discussed. Various hypotheses concerning the origin of the genus Merluccius are presented. INTRODUCTION Studies on parasites as biological indicators of their host's population status, affinities, migrations, origin and zoogeographic distribution are a valuable method to explain many problems of biology of fish. The parasitic species of a narrow specificity are particularly interesting as indicators. The parasitic copepods of the genera Chondracanthus, Brachiella and Parabrachiellaappear to play such a role in hake. During the investigations on species variability within the genus Merluccius from the Atlantic and Mediterranean Sea (Soliman, 1973), the parasitic copepods were collected in order to utilize them as possible indicators of specific affiliations and affinities between the hakes investigated.

MAURI ORA, 1985, 12: 13-53 13 PARASITIC COPEPODA FROM MARINE COASTAL FISHES IN THE KAIKOURA-BANKS PENINSULA REGION, SOUTH ISLAND, NEW ZEALAND. WITH A KEY FOR THEIR IDENTIFICATION R.L.C. PILGRIM Department of Zoology, University of Canterbury, Christchurch 1, New Zealand. ABSTRACT An introductory account of parasitic Copepoda in New Zealand waters is given, together with suggestions for collecting, examining, preserving and disposal of specimens. A key is presented for identifying all known forms from the fishes which are known to occur in the Kaikoura-Banks Peninsula region. Nine species/ subspecies ( + 2 spp.indet.) have been taken from elasmobranch fishes, 13 ( + 7 spp.indet.) from teleost fishes in the region; a further 6 from elasmobranchs and 27 ( + 1 indet.) from teleosts are known in New Zealand waters but so far not taken from these hosts in the region. A host-parasite list is given of known records'from the region. KEYWORDS: New Zealand, marine, fish, parasitic Copepoda, keys. INTRODUCTION Fishes represent a very significant proportion of the macrofauna of the coastal waters from Kaikoura to Banks Peninsula, and as such are commonly studiecl by staff and students from the Department of Zoology, University of Canterbury. Even a cursory examination of most specimens will reveal the presence of sometimes numerous parasites clinging to the outer surface or, more frequently, to the linings of the several cavities exposed to the outside sea water. The mouth and gill chambers are 14 particularly liable to contain numbers of large or small, but generally macroscopic, animals attached to these surfaces. Many are readily identified as segmented, articulated, chitinised animals and are clearly Arthropoda. -

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. -
First Record of the Snake Blenny, Ophidion Rochei Müller, 1845 (Actinopterygii: Ophidiiformes: Ophidiidae), from the Sea of Azov
J. Black Sea/Mediterranean Environment Vol. 26, No. 3: 336-342 (2020) SHORT COMMUNICATION First record of the snake blenny, Ophidion rochei Müller, 1845 (Actinopterygii: Ophidiiformes: Ophidiidae), from the Sea of Azov Oleg A. Diripasko*, Viktoriia D. Hetmanenko, Vladislav I. Kyrychenko ORCID IDs: O.A.D. 0000-0001-9267-5504; V.D.H. 0000-0002-2167-7331; V.I.K. 0000-0002-7535-0078 Institute of Fisheries and Marine Ecology, Berdyansk, UKRAINE *Corresponding author: [email protected] Abstract The first record of an Atlantic origin species, the Roche’s snake blenny Ophidion rochei Müller, 1845, in the Black Sea is provided from the south-east Sea of Azov. Its appearance in the Sea of Azov can be explained by the increase in water salinity of the sea in recent years. Keywords: Black Sea, Kerch Strait, first record, distribution, marine fish Received: 17.08.2020, Accepted: 28.11.2020 The Sea of Azov is a small and shallow enclosed sea connected to the north- eastern Black Sea through a narrow strait, the Kerch Strait, and thus belonging to the Mediterranean system of the northern Atlantic Ocean. Its main hydrological feature is low salinity (1–10‰) due to a large freshwater discharge by rivers and limited water exchange with the more saline (17–18‰) Black Sea. Salinity in the Sea of Azov is variable – lower in the large bays adjacent to the Don and Kuban river mouths and higher in the open sea, especially near the Kerch Strait. Besides, it is characterized by long-term fluctuations, both on average and in different areas, due to, mainly, freshwater discharge. -
Molecular Species Delimitation and Biogeography of Canadian Marine Planktonic Crustaceans
Molecular Species Delimitation and Biogeography of Canadian Marine Planktonic Crustaceans by Robert George Young A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Doctor of Philosophy in Integrative Biology Guelph, Ontario, Canada © Robert George Young, March, 2016 ABSTRACT MOLECULAR SPECIES DELIMITATION AND BIOGEOGRAPHY OF CANADIAN MARINE PLANKTONIC CRUSTACEANS Robert George Young Advisors: University of Guelph, 2016 Dr. Sarah Adamowicz Dr. Cathryn Abbott Zooplankton are a major component of the marine environment in both diversity and biomass and are a crucial source of nutrients for organisms at higher trophic levels. Unfortunately, marine zooplankton biodiversity is not well known because of difficult morphological identifications and lack of taxonomic experts for many groups. In addition, the large taxonomic diversity present in plankton and low sampling coverage pose challenges in obtaining a better understanding of true zooplankton diversity. Molecular identification tools, like DNA barcoding, have been successfully used to identify marine planktonic specimens to a species. However, the behaviour of methods for specimen identification and species delimitation remain untested for taxonomically diverse and widely-distributed marine zooplanktonic groups. Using Canadian marine planktonic crustacean collections, I generated a multi-gene data set including COI-5P and 18S-V4 molecular markers of morphologically-identified Copepoda and Thecostraca (Multicrustacea: Hexanauplia) species. I used this data set to assess generalities in the genetic divergence patterns and to determine if a barcode gap exists separating interspecific and intraspecific molecular divergences, which can reliably delimit specimens into species. I then used this information to evaluate the North Pacific, Arctic, and North Atlantic biogeography of marine Calanoida (Hexanauplia: Copepoda) plankton. -

Breve definición del grupo y principales caracteres diagnósticos El orden Poecilostomatoida Thorell, 1859 tiene una posición sistemática discutida. Tradicionalmente ha sido considerado un orden independiente, dentro de los 10 que conforman la subclase Copepoda; no obstante, algunos autores consideran que no existen diferencias suficientes respeto al orden Cyclopoida, del que vendrían a ser un suborden (Stock, 1986 o Boxshall & Halsey, 2004, entre otros). No obstante, en el presente volumen se ha considerado un orden independiente y válido. Antes de entrar en las singularidades del orden es preciso tratar sucintamente la morfología, ecolo- gía y biología de Copepoda, lo que se realiza en los párrafos siguientes. 1.1. Introducción a Copepoda Los copépodos se encuentran entre los animales más abundantes en número de individuos del planeta. El plancton marino puede alcanzar proporciones de un 90 por ciento de copépodos respecto a la fauna total presente. Precisamente por su número y a pesar de su modesto tamaño (forman parte de la micro y meiofauna) los copépodos representan una papel fundamental en el funcionamiento de los ecosistemas marinos. En su mayor parte son especies herbívoras –u omnívoras– y por lo tanto transformadoras de fito- plancton en proteína animal que, a su vez, sirve de alimento a todo un ejército de especies animales, inclu- yendo gran número de larvas de peces. -
Observing Copepods Through a Genomic Lens James E Bron1*, Dagmar Frisch2, Erica Goetze3, Stewart C Johnson4, Carol Eunmi Lee5 and Grace a Wyngaard6
Bron et al. Frontiers in Zoology 2011, 8:22 http://www.frontiersinzoology.com/content/8/1/22 DEBATE Open Access Observing copepods through a genomic lens James E Bron1*, Dagmar Frisch2, Erica Goetze3, Stewart C Johnson4, Carol Eunmi Lee5 and Grace A Wyngaard6 Abstract Background: Copepods outnumber every other multicellular animal group. They are critical components of the world’s freshwater and marine ecosystems, sensitive indicators of local and global climate change, key ecosystem service providers, parasites and predators of economically important aquatic animals and potential vectors of waterborne disease. Copepods sustain the world fisheries that nourish and support human populations. Although genomic tools have transformed many areas of biological and biomedical research, their power to elucidate aspects of the biology, behavior and ecology of copepods has only recently begun to be exploited. Discussion: The extraordinary biological and ecological diversity of the subclass Copepoda provides both unique advantages for addressing key problems in aquatic systems and formidable challenges for developing a focused genomics strategy. This article provides an overview of genomic studies of copepods and discusses strategies for using genomics tools to address key questions at levels extending from individuals to ecosystems. Genomics can, for instance, help to decipher patterns of genome evolution such as those that occur during transitions from free living to symbiotic and parasitic lifestyles and can assist in the identification of genetic mechanisms and accompanying physiological changes associated with adaptation to new or physiologically challenging environments. The adaptive significance of the diversity in genome size and unique mechanisms of genome reorganization during development could similarly be explored. -

Markle and William R. Curtsinger ABSTRACT Elongate dorsal appendages adorn pelagic larvae of many fishes from disparate taxa, among them larvae of the family Carapidae, wherein the singular, elongate appendage is termed a vexillum, The vexillum is a complex larval specialization of the dorsal fin and is characteristic of all carapid genera, It is motile, well vascularized, and innervated by a branch of a cranial nerve with no apparent spinal innervation. Histological studies of Echiodon dawsoni and Carapus bermudensis vexilla show a two layered epidermis with mucous cells, an arteriole and venuole, two myelinated peripheral nerve fascicles, and two collagenous central shafts. -
