(Teleostei: Characiformes): a Phylogenetic Study and a Revision of Caenotropus Gunther
The Neotropical Fish Family Chilodontidae (Teleostei: Characiformes): A Phylogenetic Study and a Revision of Caenotropus Gunther RICHARD P. VARI, RICARDO M.C. CASTRO. and SANDRA J.RAREDON i SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 577 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Folklife Studies Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. -

Porto, Porto, Portugal Received March 12, 2012 Accepted October 29, 2012 Abstract The objective of the present study was to evaluate the parasite fauna of four species of ornamental fish collected in the Chumucuí River, municipality of Bragança, Pará, Brazil. From June 2006 to December 2007. Fishes (n=307) belonging to four species were collected, including 23 specimens of Moenkhausia sanctaefilomenae (redeye tetra), 37 Carnegiella strigata (marbled hatchetfish), 7 Chilodus punctatus (spotted headstander), and 240 Astyanax bimaculatus (twospot astyanax). The parasites found belonged to three taxa: monogeneans in the gills, nematodes (larvae of Capillaria sp. and Contracaecum sp.) in the digestive tract and liver and acanthocephalans (Quadrigyrus torquatus, Q. brasiliensis and Q. nickoli) in the stomach and intestine. Astyanax bimaculatus presented higher prevalence of acanthocephalans in the wet season, and lower prevalence of nematodes in the dry season. -

According to a statistical analysis of growth curves using the method of maximum likelihood with the Gauss-Markardt algorithm, a marked difference is observed in the growth of the different samples which is attributed to the year of capture rather than to the geographical origin of fishes. It is demonstrated that the main factor affecting growth performances is the length of the rainy season, which corresponds for this species to the feeding period. Key words: Leporinusfriderici; South America; French Guiana; growth; skeletal chronobiology. I. INTRODUCTION In previous studies (Meunier et al., 1985; Lecomte et al., 1985, 1986, 1989), an annulus was shown to be formed at each of the two dry seasons of the year in three species of fish from French Guiana [Leporinusfriderici, Arius proops (Val., 1839), A. couma (Val., 1839)l. These growth zones are particularly obvious on the opercular bone and in the first ray of the pectoral fin. They were used to describe the growth of these species using the von Bertalanffy (1938) model. -

OKOGWUa, & ROBERT HANNERb aDepartment of Applied Biology, Ebonyi State University, Abakaliki, Nigeria, bDepartment of Integrative Biology, Biodiversity Institute of Ontario, University of Guelph, Guelph, Ontario, Canada, and cFisheries and Aquaculture, Ebonyi State University, Abakaliki, Nigeria (Received 17 August 2010; revised 28 October 2010; accepted 28 October 2010) Abstract Background and aims: Fishes are the main animal protein source for human beings and play a vital role in aquatic ecosystems and food webs. Fish identification can be challenging, especially in the tropics (due to high diversity), and this is particularly true for larval forms or fragmentary remains. DNA barcoding, which uses the 50 region of the mitochondrial cytochrome c oxidase subunit I (cox1) as a target gene, is an efficient method for standardized species-level identification for biodiversity assessment and conservation, pending the establishment of reference sequence libraries. Materials and methods: In this study, fishes were collected from three rivers in southeastern Nigeria, identified morphologically, and imaged digitally. DNA was extracted, PCR-amplified, and the standard barcode region was bidirectionally sequenced for 363 individuals belonging to 70 species in 38 genera. All specimen provenance data and associated sequence information were For personal use only. recorded in the barcode of life data systems (BOLD; www.barcodinglife.org). Analytical tools on BOLD were used to assess the performance of barcoding to identify species. Results: Using neighbor-joining distance comparison, the average genetic distance was 60-fold higher between species than within species, as pairwise genetic distance estimates averaged 10.29% among congeners and only 0.17% among conspecifics. -

Four types of oocytes were determined, presenting a thin zona pellucida and squamous follicle cells in all developmental stages. The yolk globules in vitellogenic oocytes are spherical and the micropyle possessed an ample vestibule and short micropylar canal. Atresic follicles were frequent, since ovulation did not occur. The histochemical reactions demonstrated the presence of neutral glycoproteins in the zona pellucida and follicle cells; glycopro- teins and lipids in the yolk globules and carboxylated acid glycoconjugates in the cortical alveoli. The knowl- edge of the reproductive parameters becomes an important tool in captivity breeding programs, reducing the fishing effort on the native stock.

A New Species of Hemibrycon(Teleostei
Neotropical Ichthyology, 5(3):251-257, 2007 Copyright © 2007 Sociedade Brasileira de Ictiologia A new species of Hemibrycon (Teleostei: Characiformes: Characidae) from the río Ucayali drainage, Sierra del Divisor, Peru Vinicius A. Bertaco*, Luiz R. Malabarba*,**, Max Hidalgo*** and Hernán Ortega*** A new characid species, Hemibrycon divisorensis, is described from the río Ucayali drainage, Loreto, Peru. The new species is distinguished from all Hemibrycon species by the presence of a wide black asymmetrical spot covering base of caudal-fin rays and extending along entire length of caudal-fin rays 9 to 12-13 (except from H. surinamensis), and a black band in the lower half of the caudal peduncle extending from the region above the last anal-fin rays to the caudal-fin base. Furthermore, it is distinguished from most species of the genus by the number of scale rows below the lateral line (4-5 vs 5-9), except H. jabonero, H. microformaa, H. orcesi, and H. surinamensis. It differs from these species by scale and fin ray counts and color pattern. The lack of a supraorbital in Hemibrycon species is discussed and confirmed. Uma nova espécie de caracídeo, Hemibrycon divisorensis, é descrita para a bacia do río Ucayali, Loreto, Peru. A nova espécie distingue-se das demais espécies de Hemibrycon pela presença de uma ampla mancha preta assimétrica na base dos raios da nadadeira caudal estendida até a extremidade dos raios 9 a 12 ou 13 (exceto de H. surinamensis), e de uma faixa preta na metade inferior do pedúnculo caudal desde a região acima dos últimos raios da nadadeira anal até a base da nadadeira caudal. -
Tetra (Paracheirodon Axelrodi, Characidae) in Its Natural Habitat
The food spectrum of the cardinal - tetra (Paracheirodon axelrodi, Characidae) in its natural habitat. Ilse WALKER1 ABSTRACT The cardinal tetra (Paracheirodon axelrodi) is the most intensively commercialized ornamental fish from the Rio Negro Basin (Amazonas State, Brasil). Analysis of the stomach and gut contents of fish caught in their natural habitats show conclusively that the cardinal is essentially a predator, feeding on the mesofauna that adheres to submerged litter, roots and waterplants. Microcrustacea and chironomid larvae (Diptera) were the most frequently ingested prey, while algae intake was relatively infrequent. It is argued that the relatively small size of the cardinals captured in their natural habitat is due to the annual migrations imposed by the inundation cycles, rather than to resource limitation, because it is known from earlier investigations of similar habitats, that these plant substrates are densely colonized by the aquatic mesofauna. Cardinals raised in captivity are larger and have higher rates of growth. KEY WORDS Rio Negro, cardinal, diet. Estratégias alimentares do cardinal-tetra (Paracheirodon axelrodi, Characidae) em seu ambiente natural. RESUMO O cardinal (Paracheirodon axelrodi) é o peixe ornamental comercializado com maior intensidade na Bacia do Rio Negro (Estado do Amazonas, Brasil). Análise do conteúdo estomacal de peixes capturados nos seus habitats naturais mostra, que o cardinal é essencialmente um predador, alimentando-se da mesofauna que está colonizando a liteira submersa, arbustos submersos, raízes flutuantes e plantas aquáticas. As presas principais são microcrustáceos e larvas de quironomídeos (Chironomidae, Diptera), enquanto ingestão de algas é pouco freqüente. Considera-se que o tamanho relativamente pequeno de cardinais capturados nos ambientes naturais é devido as migrações anuais que acompanham os ciclos anuais de enchente e vazante, e não à falta de recursos; já que é conhecido de ambientes parecidos de outros rios da região, que estes substratos aquáticos são densamente colonizados pela mesofauna.
