Full text--- The purpose of this study was to determine frequency the presentation of anothomohistopathologycal lesions compatibles with metabolic disorders related to energy and proteins in the diet of juvenile Rainbow Trout (Oncorhynchus mykiss ). Forty fish were collected randomly from the one trout hatchery, located in Huancayo-Junín, mainly taking samples of liver, kidney, gill, stomach and spleen. Between the macroscopic findings compatible with metabolic alterations observed with major frequency it was the fatty liver characterized by a brown pale coloration in 67.5% (27/40). As soon as, to the lesions histopatológicas compatible the metabolic alterations were found fat degeneration 97.5% (39/40), predominantly in grade IV and hyaline degeneration in renal tubules, 62.5% (25/40) and only 7.5% in glands gastric stomach. In gills, changes in growth such as hyperplasia (30/40), fusion (29/40) and lamellar atrophy (29/40) by 75% and 72.5% respectively, representing the highest frequency of lesions. Based on the findings, concluded that the lesions compatible the metabolic disorders were observed in a high frequency, principally related to excessive protein as hyaline degeneration in the kidney and stomach, and fatty degeneration in liver for balancing energy. Finally, the lesions on gills suggest an association between metabolic disorders and their polluting effect on the aquatic environment.

Full text--- In teleosts, the luteinizing hormone begins the final oocyte maturation previous stage of ovulation. The goal of this thesis was to evaluate the efficiency of the human Chorionic Gonadotropin (hCG), luteinizing hormone analogous, to induce in Vitro and in Vivo final oocyte maturation of Oncorhynchus mykiss “Rainbow trout” come from germinal vesicle migration stage. in Vitro final oocyte maturation, the cultures achieved only into Leibovitz L-15 medium (control) showed a very less quantity of mature oocytes. In problem cultures, the culture media that only had 5IU/ml hCG into Leibovitz medium or with Leibovitz L-15 plus 2% (v/v) Oncorhynchus mykiss serum and 5mg/ml insulin produced totality of mature oocytes at 90 hours but when it was used 10UI/ml hCG with the former media were only needed 48 hours to get the totality of mature oocytes. Although the comparative analysis between the different problem media used it showed both the serum and the insulin are important to reach the germinal vesicle breakdown stage (marker used to evaluate in Vitro oocyte maturation) in this fish. The ovulation by means in Vivo maturation was reached at 103.2 hours with first treatment (two doses: 20 and 80 IU hCG/Kg body weight), while the fishes tried with second treatment (two doses: 30 and 120 IU hCG/Kg body weight) ovulated at 43.8 hours. The control fishes reached the maturation at 31 days after their confinement into experimentation pond. These results show the dose-dependent effectiveness for human Chorionic Gonadotropin in the final oocyte maturation of Oncorhynchus mykiss.

Full text--- The aim of this study was to determine the increase in rainfall on the prevalence of Renibacterium salmoninarum detected from tissue samples (kidney and spleen) of rainbow trout in a fish farm located in the Mantaro Valley basin. The study was conducted at a fish farm in the department of Junín, in the province of Huancayo, in the months of August, September, November and February, during the rain cycle 2011-2012. The water source for the fish farm is Chiapuquio river belongs to the basin of the Mantaro Valley. The trout were randomly collected and eggs were from National and American. 60 animals were collected per sample, 240 total trout fish farm, considering a prevalence of 5%. Fish were collected in relation to the cycle of rainfall in the Mantaro Valley. August (dry season), September, November (rainy season start), and February (rainy season). DNA was extracted from kidney and spleen by phenol-chloroform technique and performed the real time PCR, yielding no Renibacterium salmoninarum genome in any of the samples, none of the rainy season cycle. We conclude that the prevalence of Renibacterium salmoninarum in fish farm study is 0%, so could not be established association between the rain cycle and prevalence of Renibacterium salmoninarum.

Full textChile es el segundo país productor de salmónidos más importante a nivel mundial. De ahí que, se convierte en el principal generador de coproductos, por sobre Noruega. Siendo el belly de la trucha arcoiris (Oncorhynchus mykiss) un coproducto desconocido, contando con escasos antecedentes de su comportamiento al conservarse refrigerado. El objetivo del presente trabajo fue determinar la pérdida de calidad funcional, química, sensorial y microbiológica del belly de trucha arcoiris (Oncorhynchus mykiss) durante su conservación en refrigeración (0º a 2º C). Se determinó la evolución de los parámetros funcionales, mediante los cuales se observó un deterioro en la funcionalidad de las proteínas presentes en el belly. También se observó el cambio de color que sufrió el belly a través del tiempo, comportándose de forma constante y sin variaciones significativas (p≥0,05). Se determinó la composición centesimal y su variación en el tiempo, obteniéndose resultados similares a aquellos presentes en la literatura. Además, el estudio contempló la determinación de pH que disminuyó en el tiempo, observándose valores de 6,62 y 6,29, al inicio y final del estudio, respectivamente. El índice de anisidina, mostró que el belly sufrió oxidación lipídica secundaria, sin embargo, este valor no superó los límites admitidos. Durante este estudio no hubo presencia de microorganismos patógenos, ni indicadores de contaminación fecal (Salmonella sp., Listeria Monocytogenes, Staphylococcus aureus), sin embargo, el recuento de aerobios mesófilos y de enterobacterias, arrojaron valores fuera de lo permitido a partir del día 10 y 24 de estudio, respectivamente. Los atributos sensoriales más sensibles para estimar el deterioro en la calidad oxidativa y textural del belly de trucha arcoiris fueron el olor típico, rancio y pútrido (crudo), elasticidad, firmeza, cohesividad y goteo. Atributos que, en conjunto con el recuento de aerobios mesófilos, sirvieron para estimar la vida útil del belly de trucha arcoiris conservado refrigerado (0º a 2º C), que fue de 12 días. De acuerdo a los resultados obtenidos mediante el análisis estadístico de los datos, se pudo determinar que existió una fuerte correlación entre los parámetros y el tiempo, y entre ellos mismos, viéndose afectada la calidad funcional, química, sensorial y microbiológica del belly de trucha arcoiris durante su conservación en refrigeración (0º a 2º C)
Chile is the second most important producer country of salmonids at worlwide level. For this reason, it turns in to the main coproducer generator, over Norway. Belly of Rainbow trout (Oncorhynchus mykiss), is an unknown coproduct, and there are very limited precedents of its behavior during chilled storaged. The aim of this study was to determined the loss of functional, chemical, sensorial and microbiology quality, during chilled storage (0ºC- 2ºC) of rainbow trout belly. Functional evolution parameters were studied, which show a deterioration in the functionality of belly proteins. Also, the belly color variation was observed trough time, behaving in a constant way and presenting no significants variations (p≥0,05) Centesimal composition and its variation in time was observed, obtaining similar results at those present in literature. The study also, contemplated pH determination, that decreased in time, being observed values from 6,62 and 6,29 at beginning and ending time of study, respectively. Anisidine index showed that belly suffered secondary lipidic oxidation, however, this value did not exceed allowed limits. During this study, neither patogens microorganisms nor faecal contamination indicators, (Salmonella sp., Listeria Monocytogenes, Staphylococcus aureus) were found in belly. Nevertheless, mesophyllic aerobic and enterobacters counts, showed values over the limits, from 10 and 24 day of study, respectively. The most sensitive sensory attributes to estimate the deterioration in the oxidating and textural quality of rainbow trout belly were typical, rancid and putrid odour (raw), elasticity, firmness, cohesiveness and dripping. Attributes that, in addition to the mesophyllic aerobic count, helped to estimate the shelf life of chilled storaged rainbow trout belly (0º to 2º C), that was 12 days. According to obtained results from statistycal analysis of data, it was possible to determine that a strong correlation existed within parameters and time, and between themselves, affecting functional, chemical, sensory and microbiologycal quality of rainbow trout belly during chilled storage (0º to 2º C)

Full textThe aquaculture is a field major priority than other for the development in our country; however, there exist many aspects in which it has not been investigated and others in which is beginning, as is the case of the use of immunoestimulants for to achieve better results in the production of the many species from economic importance. One of the stimulants investigated in other species of fish is the chitin that administered as dietary supplement enhances the immune response, providing them of the assault of pathogenic agents as Flavobacterium psychrophilum. The aim of the investigation was to evaluate immunostimulant activity of chitin administered by oral route to rainbow trout’s youths (Oncorhynchus mykiss) in immunocompetent and immunosupressed conditions e infected with a test strain, Flavobacterium psychrophilum 1947T, causing of the “cold water disease”. To demonstrate the immunostimulating with chitin there were evaluated parameters of the cellular (phagocytary activity and production of nitric oxide) and humoral (complement’s activity by alternative route and lysozyme serum’s) innate immunity. In addition it decided the necessary time of treatment with the immunostimulant to achieve the suitable one immunostimulation. Trouts were fed by pienso with and without chitin (n=20 in each case) for 2 and 4 weeks. The chitin was added to the dose of 100g/Kg of food and was supplied a proportion of 1% of biomass. Immediately of treatment both groups were immunosupressed with ciclophosphamide and infected by intramuscular route. I concluded that there exists a significant improvement of the production of nitric oxide and lysozyme serum’s activity in the immunosupressed fishes and treated with chitin in comparison with the immunocompetents fishes and not treated. The complement by alternative route and in vitro phagocytary activity did not show significant variations for both groups from two weeks of treatment.

Full text--- Rio Abiseo National Park is one of the most important regions protected in San Martin region, its purpose is to protect its untouchable resources of natural flora and fauna; the beautiful landscaping, the Abiseo river basin, their cultural resources and to promote scientific investigation. In the first order rivers that feed Abiseo river inhabit native and exotic species, including Astroblepus simonsii, Astroblepus spp. and Oncorhynchus mykiss (Walbaum 1792); the latter predominating in density and biomass. The objective of this work is to learn quantify and describe the diet and variances of Oncorhynchus mykiss (Walbaum 1792); considering the composition, proportion, diversity and feeding coincidence of different sizes and to determine the feeding habits of this species during 1989 and 1990 winters in the Montecristo first order river in National park Rio Abiseo, San Martin department. During July and August of 1989 and 1990 were collected 521 Oncorhynchus mykiss stomachs; in the Natural History Museum laboratory, using Sturges rule and sample curve of SOKHAL and ROLPH (1992) with a confidence limit of 99%, there were 408 stomachs selected of both sizes better represented in the sample (intervals of 70 mm): II (145.1 to 215.1 mm) and III (215.2 to 285.2 mm); with which the composition, abundance, biomass and taxa-prey frequency were determined. For the typing of the principal preys the Main Food Index – MFI (ZANDER, 1982) was employed, and to determine the grade of odontogenic feeding and inter-seasonal it was estimated with the Feeding Coincidence Index (ICA); with the diet composition it was determined the number of prey and diversity by size range and annual seasons.

Full text--- This study aimed to determinate the presence of Piscirickettsia salmonis agent in culture rainbow trout (Oncorhynchus mykiss) in the Mantaro river basin in the region of Junin by Indirect Inmunofluorescence test. Kidney and spleen samples at random of 180 culture rainbow trout from three fish farms of the basin (60 animals in each) were taken. The most outstanding clinical signs were sores on the skin, melanosis, irregular swimming in the water surface, swelling of the abdomen and exophthalmoses. The most outstanding lesions were petechial hemorrhage in liver, pyloric caeca and spleen, in addition to splenomegaly and pale liver. 100% of rainbow trout samples were negative for Piscirickettsia salmonis. The result indicates that this agent is not present in fish farms evaluated or the prevalence was very low and could not be detected.

Full textLa salmonicultura es una actividad que hoy reporta al país importantes beneficios tanto económicos como sociales; convirtiendo a Chile en el segundo productor mundial de salmones. De ahí la importancia de mantener la sanidad de los peces en sus distintos estados de desarrollo y así reducir al mínimo las pérdidas por enfermedades. La piscirickettsiosis cuyo agente causal corresponde a Piscirickettsia salmonis es una de las principales enfermedades que afectan la salmonicultura nacional. La presente memoria de título tuvo por objetivo caracterizar la interacción de P. salmonis con ovas de trucha arco iris (Oncorhynchus mykiss) sometidas a tratamientos con proteasas y cuya técnica de detección fue “dot blot”. La metodología “dot blot” no permitió comparar la eventual diferencia en la adhesión y/o penetración de la bacteria a la ova entre tripsina y proteinasa K. Por lo cual, esta técnica sólo se pudo utilizar como una técnica cualitativa para la detección de P. salmonis. Mediante la técnica de “dot blot” se estableció que las ovas de trucha arco iris son sensibles a la infección con la cepa SLGO-95 de P. salmonis. Esta memoria también permite establecer que la estructura proteica del corion es afectada por las enzimas proteolíticas tripsina y proteinasa K. Además, dados los resultados obtenidos post-tratamientos enzimáticos, se considera que la unión entre ovas y P. salmonis, disminuye si se degradan estructuras proteicas, por lo tanto en esta unión implicaría partes proteicas o polipéptidos. Finalmente estos resultados sugieren, pero no en forma concluyente en considerar la acción de proteínas o polipéptidos en la unión y posterior internalización de P. salmonis en el interior de la ova
