Aquaculture investigations with nuclear energy techniques; Investigaciones acuicolas con tecnicas de energia nuclear

Abstract

The culture of aquatic organisms, especially that of fishes under controlled conditions, up to their harvesting, processing, commercialization and consumption, has been pointed out as an activity that produces a lot of benefits, among them: the obtention high proteic valued food, the incorporation to the economy of lands not usefull for agriculture activities, the increment of fishing resources, the recycling of organic matter produced in the units, the regional development, the generation of employment, technologies and foreign currencies. Several research areas are identified that can be developed, using the nuclear technologies, for example in the reproduction, nutrition, diagnose and control of illnesses, environmental monitoring and quality certification of products. In the concerning to the Venezuelan aquaculture, investigations are required that need to use those techniques. For example: 1) Production of autochthonous inductive agents, by means of radioinmunoenssay (RIA), to determine the gonadotropines coming from the hypophysis of fish cultivated with the purpose of gathering the glands in its best moment, to generate the final maturation and spawn in autochthonous species. 2) Genetic improvement of cultivated species through the knowledge of the genetic load of different lines and breeds found in the natural means, and to achieve its maintenance to solve  More>>

Several research areas are identified that can be developed, using the nuclear technologies, for example in the reproduction, nutrition, diagnose and control of illnesses, environmental monitoring and quality certification of products. In the concerning to the Venezuelan aquaculture, investigations are required that need to use those techniques. For example: 1) Production of autochthonous inductive agents, by means of radioinmunoenssay (RIA), to determine the gonadotropines coming from the hypophysis of fish cultivated with the purpose of gathering the glands in its best moment, to generate the final maturation and spawn in autochthonous species. 2) Genetic improvement of cultivated species through the knowledge of the genetic load of different lines and breeds found in the natural means, and to achieve its maintenance to solve inbreeding problems, in autochthonous species aswell in as in exotic ones, by the use of marking techniques (ADE, RFLA and microsatellite techniques). 3) Nutritional and feeding studies of species under commertial culture, especially on the effect of the aflatoxins in the inputs or the portions, substances that influence in a negative way the aquatic nutrition. In this case, competitive immunoassays of enzymes bounded (ELISA) and radioinmunoessays. 4) Illness diagnose, by means of the ELISA kit, specifically of the more common illness in fishes cultivated in the country. [Spanish] El cultivo de organismos acuaticos y especialmente de peces bajo condiciones controladas hasta su cosecha, procesamiento, comercializacion y consumo ha sido senalado como una actividad que produce numerosos beneficios, entre los que destacan la obtencion de alimento de alto valor proteico, la incorporacion a la economia de tierras no aptas para la agricultura, el incremento de los recursos pesqueros, el reciclaje de materia organica producida en las unidades, el desarrollo regional, la generacion de empleos, tecnologias y divisas. Se identifican varias areas de investigacion que pueden ser desarrolladas, utilizando las tecnologias nucleares, como por ejemplo en la reproduccion, nutricion, diagnostico y control de enfermedades, monitoreo ambiental y certificacion de la calidad de productos. En lo concerniente a nuestra acuicultura, se requieren investigaciones que ameritan el uso de estas tecnicas. Por ejemplo: 1) Produccion de agentes inductores autoctonos, mediante radioinmunoensayos (RIA) para determinar la actividad de las gonadotropinas provenientes de las hipofisis de los peces cultivados con la finalidad de recolectar las glandulas en el momento optimo, desencadenantes de la maduracion final y desove en especies autoctonas. 2) Mejoramiento genetico de especies cultivadas a traves del conocimiento de la carga genetica de diferentes lineas y razas encontradas en el medio natural y lograr su mantenimiento para resolver los problemas de endogamia, tanto en especies autoctonas como exoticas, con el uso de tecnicas de marcaje del ADE, RFLA y tecnicas de microsatelites. 3) Estudios nutricionales y de alimentacion de las especies sometidas a cultivo comercial, especialmente sobre el efecto de las aflatoxinas sobre los insumos o la racion, sustancias que influyen negativamente en la nutricion acuicola. En este caso se usan inmunoensayos competitivos de enzimas ligadas (ELISA) y radioinmunoensayos. 4) Diagnostico de enfermedades, mediante el kit ELISA, especificamente de las enfermedades mas comunes que se presentan en los peces que se cultivan en el pais.}
