Appendix ............................................................................................................ ······························148 Abstract Intrarelationships of the order Gadiformes (sensu Nelson, 1994), focused on the higher gadoid taxa, were hypothesized cladistically on the basis of 49 morphological transformations. These indicated that gadiforms should be classified into three suborders and eleven families: Melanonidae (Melanonoidei), forming the sister group of all other gadiforms, Macrouridae and Steindachneriidae (Macrouroidei), and Euclichthyidae, Moridae, Macrur­ onidae, Merlucciidae, Ranicipitidae, Gadidae, Bregmacerotidae and Muraenolepididae (Gadoidei). In addition, four subfamilies were recognized in both Macrouridae (Bathygadinae, Macrourinae, Macrouroidinae and Trachyrin­ cinae) and Gadidae (Group I: Gaidropsarinae and Phycinae; Group II: Lotinae and Gadinae). Three clades were recognized within gadids: Gadiculini (Gadiculus), Gadini (Merlangius, Pollachius, Theragra, Gadus, Melanogrammus, Eleginus and Microgadus), and Trisopterini (Trisopterus, Micromesistius, Arctogadus and Boreogadus). The evolution of dorsal supernumerary fin-ray characters, gadid biogeography, phylogenetic pos­ itions of extinct gadoid genera and possible heterochrony among gadiforms are discussed. Key words: Phylogeny, Gadiformes, cladistics, character evolution, biogeography, fossils, heterochrony I. Introduction Howes (1990, 1991a) reached the following consensus: bregmacerotids and muraenolepidids belong to The order Gadiformes (sensu Nelson, 1994) comprises advanced gadoids, and each of the "Gadidae" and about 500 species included in 85 genera representing a "Merlucciidae" (sensu Nelson, 1984) are polyphyletic. number of morphologically divergent families: These conclusions also differed from the traditional view Ranicipitidae, Euclichthyidae, Macrouridae, Steindach­ that the Muraenolepididae was the most primitive family neriidae, Moridae, Melanonidae, Macruronidae, Breg­ among gadiforms (e.g., Svetovidov, 1948; Cohen, 1984). macerotidae, Muraenolepididae, Phycidae, Merlucciidae However, in spite of these cladistic studies, gadiform and

Copyright © 2005 by the Alaska Department of Fish and Game Faunal Assemblage Structure on the Patton Seamount (Gulf of Alaska, USA) Gerald R. Hoff and Bradley Stevens ABSTRACT: Epibenthic and demersal assemblages of fish and invertebrates on the Patton Seamount in the Gulf of Alaska, U.S.A., were studied in July 1999 using the Deep Sea Research Vehicle Alvin. Faunal associations with depth were described using video analysis of 8 dives from 151 to 3,375 m. A cluster analysis applied to the observations suggests three benthic faunal communities based on depth: 1) a shallow-water community (151–950 m) consisting mainly of rockfishes, flatfishes, sea stars, and attached suspension feeders, 2) a mid-depth community (400–1500 m) also consisting of numerous attached suspension-feeding organisms such as corals, sponges, crinoids, sea anemones, and sea cucumbers and fish such as the sablefishAnoplopoma fimbria and the giant grenadier Albatrossia pectoralis both of which were aggregated over a relatively narrow depth range, and 3) a deep-water community (500–3,375 m) consisting of fewer attached suspension feeders and more highly mobile species such as the Pacific grenadier Coryphaenoides acrolepis, popeye grenadier C. cinereus, Pacific flatnose Antimora microlepis, and large mobile crabs Macroregonia macrochira and Chionoecetes spp.

  • 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.

Remarks Although the accepted and most used common name for Chondrostoma nasus is “Common Nase”, it appears that the simple name “Nase” is sometimes used to refer to C. nasus (Zbinden and Maier 1996; Jirsa et al. 2010).

  • Molecular Systematics of Gadid Fishes: Implications for the Biogeographic Origins of Pacific Species
    Color profile: Disabled Composite Default screen 19 Molecular systematics of gadid fishes: implications for the biogeographic origins of Pacific species Steven M. Carr, David S. Kivlichan, Pierre Pepin, and Dorothy C. Crutcher Abstract: Phylogenetic relationships among 14 species of gadid fishes were investigated with portions of two mitochondrial DNA (mtDNA) genes, a 401 base pair (bp) segment of the cytochrome b gene, and a 495 bp segment of the cytochrome oxidase I gene. The molecular data indicate that the three species of gadids endemic to the Pacific Basin represent simultaneous invasions by separate phylogenetic lineages. The Alaskan or walleye pollock (Theragra chalcogramma) is about as closely related to the Atlantic cod (Gadus morhua) as is the Pacific cod (Gadus macrocephalus), which suggests that T. chalcogramma and G. macrocephalus represent separate invasions of the Pacific Basin. The Pacific tomcod (Microgadus proximus) is more closely related to the Barents Sea navaga (Eleginus navaga) than to the congeneric Atlantic tomcod (Microgadus tomcod), which suggests that the Pacific species is derived from the Eleginus lineage and that Eleginus should be synonymized with Microgadus. Molecular divergences between each of the three endemic Pacific species and their respective closest relatives are similar and consistent with contemporaneous speciation events following the reopening of the Bering Strait ca. 3.0–3.5 million years BP. In contrast, the Greenland cod (Gadus ogac) and the Pacific cod have essentially identical mtDNA sequences; differences between them are less than those found within G. morhua. The Greenland cod appears to represent a contemporary northward and eastward range extension of the Pacific cod, and should be synonymized with it as G.

    I . RADIOMETRIC AGE DETERMINATION OF THE GIANT GRENADIER (A/batrossia pectoralis) USING 210Pb: 226Ra DISEQUILIBRIA A thesis submitted to the faculty of San Francisco State University in partial fulfillment of the requirements for the degree Master of Science in Marine Science by Erica Janis Burton San Francisco, California December, 1999 Copyright by Erica Janis Burton 1999 RADIOMETRIC AGE DETERMINATION OF THE GIANT GRENADIER (Aibatrossia pectoralis) USING 210Pb: 226 Ra DISEQUILIBRIA Erica Janis Burton San Francisco State University 1999 Age estimates determined from growth increments in sagittal otolith sections indicated that Albatrossia pectoralis is slow growing (K :<:: 0.023) and lives up to 56 years. Growth increments found in otolith sections, however, were difficult to interpret. The von Bertalanffy growth function for A. pectoralis otolith section age estimates did not fit size-at-age data well. To validate age and longevity estimates, ages were determined using the radioactive disequilibria of 210Pb: 226 Ra in otolith cores from adult A. pectoralis. Radiometric and growth increment ages agreed for 6 of the 12 pooled otolith age-groups. Radiometric age determination confirmed longevity to at least 32 years for females and 27 years for males. Additional age and longevity estimates are still necessary to develop an informed fishery management plan for A. pectoralis.
