The Complete Mitochondrial Genome of the Small Yellow Croaker and Partitioned Bayesian Analysis of Sciaenidae Fish Phylogeny
Genetics and Molecular Biology, 35, 1, 191-199 (2012) Copyright © 2012, Sociedade Brasileira de Genética. Printed in Brazil www.sbg.org.br Research Article The complete mitochondrial genome of the small yellow croaker and partitioned Bayesian analysis of Sciaenidae fish phylogeny Yuanzhi Cheng, Rixin Wang, Yuena Sun and Tianjun Xu Laboratory for Marine Living Resources and Molecular Engineering, College of Marine Science, Zhejiang Ocean University, Zhoushan, Zhejiang, P.R. China. Abstract To understand the phylogenetic position of Larimichthys polyactis within the family Sciaenidae and the phylogeny of this family, the organization of the mitochondrial genome of small yellow croaker was determined herein. The com- plete, 16,470 bp long, mitochondrial genome contains 37 mitochondrial genes (13 protein-coding, 2 ribosomal RNA and 22 transfer RNA genes), as well as a control region (CR), as in other bony fishes. Comparative analysis of initia- tion/termination codon usage in mitochondrial protein-coding genes of Percoidei species, indicated that COI in Sciaenidae entails an ATG/AGA codon usage different from other Percoidei fishes, where absence of a typical con- served domain or motif in the control regions is common. Partitioned Bayesian analysis of 618 bp of COI sequences data were used to infer the phylogenetic relationships within the family Sciaenidae. An improvement in harmonic mean -lnL was observed when specific models and parameter estimates were assumed for partitions of the total data. The phylogenetic analyses did not support the monophyly of Otolithes, Argyrosomus, and Argyrosominae. L. polyactis was found to be most closely related to Collichthys niveatus, whereby, according to molecular systematics studies, the relationships within the subfamily Pseudosciaenidae should be reconsidered. -

This is a revised and updated checklist of the parasites of medaka published in Japanese in 2012. The parasites, including 27 nominal species and those not identified to species level, are listed by higher taxa as follows: Ciliophora (no. of nominal species: 6), Cestoda (1), Monogenea (1), Trematoda (9), Nematoda (3), Bivalvia (5), Acari (0), Copepoda (1), and Branchiura (1). For each parasite species listed, the following information is given: its currently recognized scientific name, any original combination, synonym(s), or other previous identification used for the parasite from medaka; site(s) of infection within or on the host; known geographical distribution in Japanese waters; and the published source of each record. A skin monogenean, Gyrodatylus sp., has been encountered in research facilities and can be regarded as one of the most important parasites of laboratory-reared medaka in Japan. -

Danube Research-Consulting S.R.L., 89bis Câmpia Libertății Street, 825200, Isaccea, Romania ‡The first two authors contributed equally to this work. Abstract Huchen or Danube salmon (Hucho hucho, Linnaeus, 1758) is an economically and ecologically valuable salmonid species, among the most endangered fish species inhabiting the Danube basin. Consequently, appropriate conservation measures are required to prevent the species extinction. Although H. hucho is a poorly studied species, there are several studies on other salmonid species regarding fast growth markers. Following these studies, the main purpose of the current study was to determine growth-related SNPs in myostatin gene in H. hucho. Therefore, we analysed 20 aquaculture individuals of same age separated in two groups according length and weight, by sequencing the amplification product of SaMSTNb23 and SaMSTNb33 primers pairs. We also statistically analysed the differences in the development of individuals over time regarding total length, weight and head length. Significantly variations were observed (p < 0.001) for the measured traits in both groups. Regarding the genetic analysis, we observed nine SNPs in the mstn gene structure. Considering these results, it appears that the analysed markers are not appropriate for genetic analysis of growth traits in H. -

Received: 20 March 2014; in revised form: 15 April 2014 / Accepted: 15 April 2014 / Published: 8 May 2014 Abstract: In order to determine the absolute configuration of naturally occurring alloxanthin, a HPLC analytical method for three stereoisomers 1a–c was established by using a chiral column. Two authentic samples, (3S,3′S)- and meso-stereoisomers 1b and 1c, were chemically synthesized according to the method previously developed for (3R,3′R)-alloxanthin (1a). Application of this method to various alloxanthin specimens of aquatic animals demonstrated that those isolated from shellfishes, tunicates, and crucian carp are identical with (3R,3′R)-stereoisomer 1a, and unexpectedly those from lake shrimp, catfish, biwa goby, and biwa trout are mixtures of three stereoisomers of 1a–c. Keywords: carotenoid; alloxanthin; synthesis; chiral HPLC separation; absolute configuration 1. Introduction Alloxanthin (1) (Figure 1) was first isolated from Cryptomonas algae [1] and its structure was determined to be 7,8,7′,8′-tetreradehydro-β,β-carotene-3,3′-diol by MS, IR and 1H-NMR spectroscopies [2]. -

Rivers in the Japanese archipelago, separated from the continent of Asia by about 17 Ma, have experienced an intermittent exchange of freshwater fish taxa through a narrow land bridge generated by lowered sea level. As the Korean Peninsula and Japanese archipelago were not covered by an ice sheet during glacial periods, phylogeographical analyses in this region can trace the history of biota that were, for a long time, beyond the last glacial maximum. In this study, we analyzed the phylogeography of four freshwater fish taxa, Hemibarbus longirostris, dark chub Nipponocypris temminckii, Tanakia ssp. and Carassius ssp., whose distributions include both the Korean Peninsula and Western Japan. We found for each taxon that a small component of diverse Korean clades of freshwater fishes Citation: Taniguchi, S.; Bertl, J.; migrated in waves into the Japanese archipelago to form the current phylogeographic structure of Futschik, A.; Kishino, H.; Okazaki, T. -

Results of this study revealed that the bacterial community throughout the river primarily consisted of a small number of highly abundant species that comprise a “core microbial community” that was stable both in terms of community membership and inferred functional traits. Variation in community membership and species abundances were primarily influenced by physicochemical parameters (e.g. pH and temperature) rather than spatial distance, and a reproducible community structure occurred annually toward the late summer. Furthermore, specific bacterial orders were related to chemical concentrations that co-varied with surrounding land use, suggesting that increases in abundance of these orders may be indicative of specific types of contamination throughout the river. Therefore, assessment of the total bacterial community provides more information about water quality and contamination sources than could be previously gleaned from traditional enumeration of indicator bacteria like Escherichia coli. -

AGE AND GROWTH OF TROPICAL TUNAS FROM THE WESTERN CENTRAL PACIFIC OCEAN, AS INDICATED BY DAILY GROWm INCREMENTS AND TAGGING DATA. LEROY B. South Pacific Commission, Nouméa, New Caledonia The Oceanic Fisheries Programme of the South Pacific Commission is currently pursuing a research project on age and growth of two tropical tuna species, yellowfm tuna (Thunnus albacares) and bigeye tuna (Thunnus obesus). The daily periodicity of microincrements forrned with the sagittal otoliths of these two spceies has been validated by oxytetracycline marking in previous studies. These validation studies have come from fishes within three regions of the Pacific (eastem, central and western tropical Pacific). Otolith microincrements are counted along transverse section with a light microscope.
