Documentos Históricos - IX. Serie Evaluación de los Recursos Naturales de la Argentina - CFI. Recursos Acuáticos Vivos: Iconografía ictiológica, de Tomás L. Marini y Rogelio B. López.

El Programa para el estudio y uso sustentable de la Biota Austral (Probiota), como un modesto homenaje, rescata a cuarenta y cinco años de su publicación la iconografía ictiológica de la obra Recursos Acuáticos Vivos incluída en la Serie Evaluación de los Recursos Naturales de la Argentina y editada por el Consejo Federal de Inversiones (CFI) en 1963. Para la ejecución de esta obra el CFI contrató a los doctores Tomás L. Marini y Rogelio B. López ; las ilustraciones de peces que se incluyen fueron preparadas por la Profesora Claudina Abella de López. Este es otro paso dirigido a la consolidación de nuestra disciplina, ya que manteniendo siempre el recuerdo vivo del pasado lograremos afianzar el presente, lo que nos permitirá planificar con fundamentos nuestro futuro.

Étude histologique du cycle sexuel de l'albacore (Thunnus albacares) Bonnaterre 1788

The evolution of the general microscopic structure of the ovary of Thunnus albacares related to the gonad index, and the ovocyte maturation process were studied. Some stages of the males sexual maturation were characterized.

Morfología comparativa de las células sanguíneas del tiburón nodriza Ginglymostoma cirratum (Bonnaterre, 1788) con diversos peces.

Se llevó a cabo una comparación entre la morfología de las células de la sangre periférica de 9 tiburones nodriza, de una raya americana y 9 peces teleósteos; además, se determinó la fórmula leucocitaria y la cantidad total de eritrocitos y leucocitos/mm 3 de sangre para cada pez estudiado. English Abstract This work is a comparation of the blood cells morphology between 9 nurse sharks, southern stingray and 9 bone fishes, moreover, it was maked a differential leucocytes count, red and white cells counts by blood mm3 for any fish.

Ictiólogos de la Argentina: Tomás Leandro Marini

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.

Effects of gamma radiation on nutritional and microbial quality of Pampus chinensis (Euphrasen 1788)

To evaluate the efficiency of gamma radiation in combination with low temperature Chinese pomfret, Pampus chinensis were preserved by the treatment of different doses of gamma radiation (3, 5 and 8 KGy) at freezing temperature (-20°C) during 90 days of storage period. Quality assessments for fish were carried out at an interval of 15 days during the storage period. Quality assessments were done by organoleptic, chemical (Total Volatile Nitrogen, TVN and Trimethylamine, TMA) and microbiological (Total Bacterial Count, TBC and Total Mould Count, TMC) evaluation. From the analysis of all parameters, maximum shelf-life was observed for irradiated (8 KGy) sample. It remained acceptable up to 75 days and that was the highest duration among 4 types of samples.
