Amphidromy in Shrimps: a Life Cycle Between Rivers and the Sea
Lat. Am. J. Aquat. Res., 41(4): 633-650, 2013 Amphidromy in shrimps: a life cycle 633 “Studies on Freshwater Decapods in Latin America” Ingo S. Wehrtmann & Raymond T. Bauer (Guest Editors) DOI: 103856/vol41-issue4-fulltext-2 Review Amphidromy in shrimps: a life cycle between rivers and the sea Raymond T. Bauer1 1Department of Biology, University of Louisiana at Lafayette, Lafayette, Louisiana, 70504-2451 USA ABSTRACT. Amphidromy is a diadromous life history pattern, common in tropical and subtropical freshwater caridean shrimps, in which adults live, breed and spawn small-sized embryos in freshwater but have extended larval development (ELD) in marine waters. Most completely freshwater species spawn large embryos with either direct or abbreviated larval development (ALD). An important benefit of amphidromy is dispersal among river systems via marine larvae, which increases their access to alternative habitats. Thus, amphidromous species have much broader geographic distributions than closely related completely freshwater ones with ALD. ALD and freshwater ELD species appear to have evolved from amphidromous species with marine ancestors. Delivery of larvae to the sea in many amphidromous species is accomplished by upstream hatching and river drift of larvae to the sea. In other species, the females themselves apparently migrate down to marine waters to spawn. After development, the postlarvae must find a river mouth and migrate upstream to the adult habitat. Migrations occur at night, with juveniles swimming or crawling along the river or stream bank. Larvae are released during the wet or flood season of the year, while juvenile migrations take place during the dry or low-flow season. -

A Revision of the South American Fishes of the Genus Nannostomus Giinther (Family Lebiasinidae) STANLEY H. WEITZMAN and J. STANLEY COBB SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 186 SERIAL PUBLICATIONS OF THE SMITHSONIAN INSTITUTION The emphasis upon publications as a means of diffusing knowledge was expressed by the first Secretary of the Smithsonian Institution. In his formal plan for the Insti- tution, Joseph Henry articulated 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 keynote of basic research has been adhered to over the years in the issuance of thousands of titles in serial publications under the Smithsonian imprint, com- mencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Annals of Flight Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in History and Technology In these series, the Institution publishes original articles and monographs dealing with the research and collections of its several museums and offices and of professional colleagues at other institutions of learning. These papers report newly acquired facts, synoptic interpretations of data, or original theory in specialized fields. These pub- lications are distributed by mailing lists to libraries, laboratories, and other interested institutions and specialists throughout the world. Individual copies may be obtained from the Smithsonian Institution Press as long as stocks are available. -
Cryphiops Caementarius (Molina, 1782)

Primer y segundo par de patas caminadoras con quela o tenaza terminal; el segundo par mucho más grande que el primero y una de las patas de mayor tamaño que la opuesta (Jara 1994). El segundo par de patas del macho es distinto del de la hembra; la mayor anchura de los extremos del segundo segmento abdominal, en proporción a la longitud del abdomen y la relación cefalotoráxica, nos dan la evidencia de un dimorfismo sexual (Castro 1966). El espécimen macho más grande medido en la Colección del Instituto de Zoología (UACh) alcanzó a 59 mm, mientras que el más grande registrado en la literatura alcanzó 67 mm (Jara 1994). Rasgos distintivos ASPECTOS REPRODUCTIVOS: La mayor parte de los ejemplares migran activamente hacia la desembocadura de los ríos para la reproducción , liberar las larvas en los estuarios o zonas del potamon. En cuevas los machos tienen varias hembras que fertilizan después de la muda. -

C. P. 81101. Abstract Eyestalk ablation is the most common procedure used to induce crustacean reproduction in commercial hatcheries. However, other physiological and metabolic processes are affected by the removal of the X-organ sinus gland complex located in the eyestalk. In this study, the effect of unilateral eyestalk ablation on the concentration of several hemolymph metabolites, reproduction and immune function in female Macrobrachium americanum was investigated. Molting cycle time was not significantly P( =0.17) shortened in eyestalk-ablated females. However, an increased number of molts was observed in the eyestalk-ablated group because survival was significantly higher due to increased passivity and lowered aggression. As M. americanum has closed thelyca, reproduction was not accelerated after eyestalk ablation compared to control prawns. Food intake (P=0.007) and oxygen consumption (P=0.047) were both higher in eyestalk-ablated females. Concentrations of protein and glucose in hemolymph were not affected (P=0.54 and P=0.19, respectively), indicating that the demand for these metabolites was met. Glucose was metabolized by aerobic metabolism as shown by the lower lactate concentration (P=0.02) and higher respiration rate after ablation. -

Abstract Comparative cytogenetic analyses of hatchetfishes Carnegiella marthae and Carnegiella strigata (Gasteropelecidae) from the Rio Negro basin were performed using conventional Giemsa staining, silver (Ag) -stain- ing and C-banding. The diploid chromosome numbers of both species equaled 2n = 50 but their karyotypes were dis- tinct. We found evidence for sex chromosomes in C. marthae since karyotype of males presented 20M+12SM+4 ST + 14 A and ZZ ST chromosomes while the females presented 20M+12SM+4ST+14AandZWSTchromo- somes of distinct size. Conversely, C. strigata presented 4M+4SM+2ST+40Achromosomes without sex chro- mosome heteromorphism. Karyotypes of both species had two NOR-bearing SM chromosomes of distinct size indicating the presence of multiple NOR phenotypes. The sex chromosome pair had specific C-banding pattern al- lowing identification of both Z and W. This heteromorphic system has previously been described for the gaste- ropelecids. Key words: fish cytogenetics, karyotype differentiation, NOR phenotypes, heteromorphic sex chromosome system, cytotaxonomy. Received: August 22, 2006; Accepted: April 18, 2007. The family Gasteropelecidae (Characiformes) is a strigata) has been the subject of cytogenetic studies. -
Maduración, Muda Y Crecimiento De Hembras Del Camarón De Río Cryphiops Caementarius Con Ablación Del Pedúnculo Ocular, En Condiciones De Laboratorio
Maduración, muda y crecimiento de hembras del camarón de río Cryphiops caementarius con ablación del pedúnculo ocular, en condiciones de laboratorio Maturation, moulting and growth of females prawn Cryphiops caementarius with eyestalk ablation, in laboratory conditions. Reyes-Avalos, Walter1; Gladis Melgarejo-Velásquez, Gladis2; Rojas-González, Elizabeth2 RESUMEN El objetivo fue estudiar la maduración, muda y crecimiento de hembras de C. caementarius con ablación del pedúnculo ocular. Se emplearon 25 hembras con ovarios en estado II y en muda C y D1: 5 hembras con pedúnculos oculares intactos; 10 con ablación de un solo pedúnculo ocular y 10 con ablación de ambos pedúnculos oculares. El experimento duró 98 días y abarcó época no reproductiva. La ablación unilateral no afectó la maduración ovárica ni la duración del ciclo de muda, solo ocasionó reducido crecimiento por muda (4% en LC) y moderada mortalidad (40%). En cambio la ablación bilateral ocasionó maduración temprana (25 días), menor duración del ciclo de muda (22 días), mayor crecimiento por muda (8% en LC), alta mortalidad (65%) y cambios en la relaciones de las medidas morfométricas. La ablación unilateral y bilateral no alteraron la duración de los estados de muda AB ni C, pero la ablación bilateral redujo la duración del estado D principalmente la división D 1’. Palabras clave: Ablación, maduración, muda, crecimiento, camarón. ABSTRACT The aim was to determine the effects of ablation unilateral and bilateral eyestalk, in maturation, moult and growth female C. caementarius. Twenty-five females were used with ovaries in stage II and in moult C and D1: five females with eyestalk intact, ten with ablation of a single eyestalk and ten with ablation of both eyestalks. -

Travasoss (1952) undertook the revision of the subgenus Jobertina of Pellegrin 1909 (Characidium with incomplete lateral line), he expressed some restrictions as he did not have the possibility to examine the type -species (= interruptum), the unique specimen being in Paris. Thanks to Professeur G u i b é of the Museum National d'Histoire Naturelle, I had this opportunity in the course of a new revision required by the discovery of a species from French Guiana. The purpose of this paper is then to give a redescription with figure of the type, the descrip- tion of the new species and to end with some taxonomical and phyloge- netic hypothesis. I.
