Emiliano Mac Donagh - Un “Cuento de viejas” y otros cuentos viejos.

Al revisar viejos papeles familiares de nuestro padre, el Dr. Emiliano Mac Donagh (1896 – 1961) hemos descubierto, como escondidos, unos cuentos breves publicados entre 1929 y 1934. Ficcionales, pintorescos, no han figurado en la nómina de sus escritos, con excepción de El Naturalista, publicado en 1929 en el diario La Nación, y recientemente reproducido en la serie ProBiota (http://ictiologíaargentina.blogspot.com/16) Ofrecemos a la curiosidad de los ictiólogos los tres relatos publicados en 1930 en la revista Número, editada en Buenos Aires. Tanto Un cuento de viejas, como El sabio ebrio, y La quimera, el gallo y el elefante tienen a los peces como centro de interés. En los escritos de Emiliano Mac Donagh, que abarcan desde 1922 hasta 1960 con más de ciento setenta títulos, predominan los trabajos científicos alternando con estudios sobre historia de la biología y de los biólogos, o la preocupación por el cuidado del ambiente y temas relacionados. Sin excepción, aparece la zoología como tema vertebral, ya sea analizando una espina de bagre en la calma del laboratorio, ya sea relatando expediciones zoológicas al interior de nuestro país. Coexisten el detalle mínimo que entrega el microscopio con la aventura a campo abierto, pero el estilo es siempre descriptivo, pegado a la realidad, y despojado de cualquier intento de fantasía que traicionaría el rigor requerido por la ciencia. En los breves relatos aquí presentados, en cambio, el autor escapa de la formalidad, incursiona en un género más liberal en sus normas y deja volar su imaginación y su fino sentido de la ironía. Lo hace sin abandonar el asunto que más le atrae: la naturaleza, y en ella, la vida animal. Si bien los cuentos comparten temas centrales del resto de la producción, aquí no encontramos la exactitud fotográfica ni el análisis desapasionado, sino que la anécdota es imaginada y los escenarios reales se ven transformados por enfoques oníricos. Algunos personajes parecen el fiel retrato de alguien conocido mientras que otros suenan esquemáticos, vacíos. La mirada es humorística y a la vez crítica, gozosa sin dejar de ser analítica. Este período de “autor literario” en vez de “relator científico” dura poco: sólo cinco cuentos en cinco años. En la vasta producción no hay otros intentos de recurrir a la ficción para atraer el interés del público general hacia los admirables y admirados habitantes de las aguas. Quizás podríamos encontrar ecos del monólogo final de El sabio ebrio en el ensayo La belleza de los peces (Revista de Educación, La Plata, 1957) pero en este último el estilo es académico. El cambio de género literario podría sugerir un deseo de cambio vocacional, el cansancio frente a la aparente monotonía y estrictez de los registros científicos. Al plantear el dilema entre observar seres vivos en su medio natural o conservar sus cuerpos para los estudios científicos se insinuaría una encrucijada profesional. En 1930 habrá sido una disyuntiva, aludida en el recurrente contraste entre ambientes cerrados, poblados de frascos, vitrinas y mesas de taxidermia en contraposición con la abierta amplitud de ríos y playas, bosques y cielos. Aludida, también, al atribuir a personajes que las encarnan, dos tipos de sabiduría: una erudita, nacida del estudio, y otra pragmática, forjada en la experiencia. Sin embargo, el tema medular sigue siendo la ictiología: los peces, sus vidas y ámbitos, los nombres que les damos. El nuevo estilo revelaría más bien la intención de jerarquizar los asuntos dilectos envolviéndolos en una forma literaria más libre – y supuestamente más elevada. Creemos captar un latido de euforia, el impulso de compartir la emoción de un descubrimiento, el deseo de conservar la mirada ingenua y la capacidad de asombro ante el maravilloso mundo natural que nos rodea. Que esto se logre más acabadamente por medio de un cuento que a través de un informe, y que la ficción alcance mayor audiencia con la cual compartir la gozosa experiencia del conocimiento, son las cuestiones que nos deja pendientes este naturalista que – por breve tiempo – se volvió cuentista.

Technical report on the environmental monitoring of the cage area at the Source of the Nile (SON) Fish Farm for quarter 1: January-March 2015

Source of the Nile (SON) fish farm is located at Bugungu in Napoleon Gulf, northern Lake Victoria. The proprietors of the farm have a collaborative arrangement with NaFIRRI, a lead agency in fisheries research and innovations, to undertake quarterly environment monitoring surveys at the farm. The agreed areas for monitoring are: selected physico-chemical parameters (i.e. temperature, dissolved oxygen, pH, conductivity, secchi depth); total suspended solids (TSS); nutrient status; BOD5) and biological parameters (i.e. algae, zooplankton, macro-benthos and fish). Water and biological samples as well as field measurements were taken at 3 sites: within the fish cage rows (WIC/experimental), upstream (USC/control) and downstream (DSC) of the fish cages. The key research question was: Does fish cage operations have impacts on the water quality and aquatic biota in and around the SON cage fish farm? The environment monitoring surveys were projected to cover a full calendar year (i.e. from January to December). The first surveys were undertaken in 2011 and have continued on an annual basis since then. The present report presents field observations made for the fourth quarter survey undertaken in November 2014 and provides a scientific interpretation and discussion of the results with reference to possible impacts of the cage facilities to the water environment and the different aquatic biota in and around the fish cage site.
