Raúl Adolfo Ringuelet (1914 1982): Una síntesis de su trayectoria con énfasis en sus contribuciones a la Ictiología y Limnología.

Historia de la Ciencia fue una materia ofrecida en 2003, por el curso de Posgrado en Ciencias Ambientales (PEA) de la Universidad Estadual de Maringá, PR, Brasil, dictada por la profesora Luiza Marta Bellini. Durante el curso de la misma, se discutía sobre la historia y filosofía de vida de los científicos que brillaron o, por el contrario, pasaron desapercibidos por la historia del pensamiento humano. Al final del término de la materia, se logró compilar un libro llamado Ecólogos e suas histórias: Um olhar sobre a construção das ideas ecológicas (Pelicice et al., 2010). El capitulo diez del libro, es un comentario sobre algunos pioneros que contribuyeron para el desarrollo de la Limnología fluvial en Sudamérica. Dos fueron tratados en ese capítulo, Harald Sioli y Juan José Neiff (ver Arenas‐Ibarra et al., 2010). Sin embargo, la idea principal del capítulo era incluir también a los doctores Argentino Aurelio Bonetto y Raúl Adolfo Ringuelet, pero cuestiones relativas al formato y espacio de cada capítulo, impidieron mantener la integridad original de éste y el mayor conocimiento de las contribuciones de estos dos destacados investigadores argentinos en tierras brasileras. Si bien esta omisión fue compensada en parte por el artículo de Arenas‐Ibarra & Souza‐Filho (2010) en el que se resaltan las figuras de Bonetto y Rzóska como precursores de la Limnología fluvial, quedó aún pendiente este reconocimiento por parte de los autores de este documento a Raúl Ringuelet. Con motivo de que en el transcurso de este año se cumplieron treinta años del fallecimiento del Dr. Raúl Adolfo Ringuelet, decidimos, por invitación de Hugo Luis López, publicar el material recopilado durante la materia cursada en la Universidad Estadual de Maringá (UEM, Brasil), actualizándola con nuevos datos proporcionados por Hugo López y Juan José Neiff. Este trabajo es una síntesis de las ideas de Raúl Adolfo Ringuelet, quien sin duda se encuentra entre los pioneros de la ictio‐limnología local y sudamericana.

Ictiólogos de la Argentina: Camilo Antonio Daneri

This series will include all those people who, by means of their contributions, great and small, played a part in the consolidation of ichthyology in Argentina. The general plan of this work consists of individual factsheets containing a list of works by each author, along with reference bibliography and, whenever possible, personal pictures and additional material. The datasheets will be published primarily in chronological order, although this is subject to change by the availability of materials for successive editions. This work represents another approach for the recovery and revalorization of those who set the foundations of Argentine ichthyology while in diverse historical circumstances. I expect this to be the beginning of a major work that achieves the description of such a significant part of the history of natural sciences in Argentina.

Peces continentales de la Argentina: Iconografía. Cheirodon interruptus

The goal of this work is to present a collection of drawings and figures depicting the species present in our country. To achieve this, our main sources of information have been the works of Ringuelet et al. (1967), Reis et al. (2003), and López et al. (2003; 2006), as well as the online databases of W. N. Eschmeyer and Fish Base. Each species has an individual factsheet with selected images, including some from anatomical research works. All the works referenced are mentioned in each factsheet. This is an open-ended publication. As such, it will require permanent updating,which will depend on the good will and collaboration of the ichthyological community. As compilers, we understand that this contribution not only provides valuable information, but also highlights the work of men and women who are part of the rich history of our national and regional ichthyology.

Peces continentales de la Argentina: Bibliografía. Cheirodon interruptus

The goal of this work is to compile the existing information about the species present in our country. This has been done by means of datasheets that list both local references and reviews by foreign authors that include Argentine taxa. The main information sources consulted were Ringuelet et al. (1967), CLOFFSCA (2003), López et al. (2003; 2006), Liotta (2006) and the online databases of W. N. Eschmeyer and Fish Base. This is an open-ended publication. As such, it will require permanent updating,which will depend on the good will and collaboration of the ichthyological community. With this contribution, we hope to help to build a database of the freshwater fish of Argentina. The completion of this project will provide support to diverse plans emanating from different sectors, as well as promote the diffusion of this field of research and reaffirm Argentina’s sovereign rights over our natural resources.

Esta contribución forma parte de los resultados del PICT 153 de la Agencia Nacional de Promoción Científica y Técnica, dirigido por la autora, entre cuyos objetivos se encuentra la transferencia del conocimiento. Es así, que la presente iconografía, tiene como propósito difundir a diferentes niveles de la sociedad la ictiofauna de una de nuestras provincias mesopotámicas contribuyendo de esta manera a la educación ambiental y al manejo y conservación de los recursos naturales.

Cholesterolgehalte in Fischereierzeugnissen vom Deutschen Markt

Kurzfassung Zahlreiche Fischereierzeugnisse aus dem Deutschen Handel wurden auf ihren Gehalt an Cholesterol hin analysiert. Zur Analyse gelangten 38 verschiedene Dauerkonserven von acht Fischarten, 4 Produkte kalt geräucherter Atlantischer Zuchtlachs in Scheiben, 10 Garnelenarten und 25 Fischstäbchenerzeugnisse von 5 Tierarten in Verbraucherpackungen. Bei den Dauerkonserven lagen die Gehalte zwischen 24 und 40 mg/100 g. Zwei Ausnahmen bildeten Sprottenkonserven mit durchschnittlich 107 mg/100 g und Oktopuskonserven mit 196 mg/100 g. Die Garnelenarten variierten zwischen 84 und 161 mg/100g. Die kalt geräucherten Lachsscheiben wiesen nur eine kleine Bandbreite im Cholesterolgehalt zwischen 38 und 43 mg/100 g auf. Alle Fischstäbchen aus Magerfischen enthielten niedrige Gehalte an Cholesterol (Pangasius hypophthalmus 25, Seehecht 19, Seelachs 31 und Alaska Seehecht 28 mg/100 g), während die zwei Proben aus Tintenfischen über 100 mg/100 g lagen. Abstract Numerous fishery products from the German market have been analysed for their content of cholesterol. In total 38 different canned fishery products produced from 8 species, 4 products of sliced cold smoked Atlantic salmon, 10 species of crustacean shellfish and 25 different brands of consumer packages of fish fingers (produced from 5 species) were investigated. Canned fishery products contained amounts of cholesterol ranging from 24 to 40 mg/100 g. However, canned sprats exhibit cholesterol content as high as 107 mg/100g and canned octopus 196 mg/100 g. Crustacean shellfish was found to contain cholesterol content between 84 and 161 mg/100 g depending of species. Sliced cold smoked salmon in 200 g consumer packages showed only a little variation in cholesterol content (38-43 mg/100 g). In all fish fingers produced from lean fish species low cholesterol content (pangasius or sutchi catfish 25, hake 19, saithe 31, and Alaska Pollack 28 mg/100 g, respectively) was found, whereas two products produced from squid exceeded 100 mg/100 g.

A través de esta serie intentaremos conocer diferentes facetas personales de los integrantes de nuestra “comunidad”. El cuestionario, además de su principal objetivo, con sus respuestas quizás nos ayude a encontrar entre nosotros puntos en común que vayan más allá de nuestros temas de trabajo y sea un aporte a futuros estudios históricos. Esperamos que esta iniciativa pueda ser otro nexo entre los ictiólogos de la región, ya que consideramos que el resultado general trascendería nuestras fronteras.
