The aim of the study was to describe theoretical-practical tools of the professional teaching and learning process as a category of university teaching. The study was carried out from January to June 2021, where teaching was considered as the first university mission, the category that refers to the professional process of teaching and learning. In this category, six theoreticalpractical tools are mentioned: 1st) establishes the didactic strategies, 2nd) selects the content, 3rd) identifies the learning resources, 4th) schedules the activities, 5th), considers the type of evaluation, and 6th) the learning outcome is diagnostic and then conceptualized for description. It is indicated that every process aims to optimize methods and techniques in the teaching and learning relationship to move between skill levels. In the process of updating and relevancy of knowledge, a definition of the pr...

The aim of study was to determine cell concentration and dry biomass in three species of marine microalgae: Chlorella vulgaris, Nannochloropsis oculata and Tetraselmis striata. The strains were supplied by the Ilo Coastal Laboratory belonging to the Peruvian Institute of the Sea (IMARPE) and then, the microalgae were conditioned to be cultivated in a semi-controlled medium. The phases of the microalgae culture consisted of the cepario, initial, intermediate and massive. The order of maximum cellular concentration (cel/mL) for the microalgae was Nannochloropsis oculata > Chlorella vulgaris > Tetraselmis striata where N. oculata represented 7.63 times higher than T. striata. In the case of biomass, the order corresponded to: C. vulgaris > T. striata > N. oculata, with a 1.32 g difference. It was concluded that the microalgae species Chlorella vulgaris indicated the greatest adv...

The nutritional value during the preparation and conservation of the silage is still of great interest for human and animal consumption. The objective of the study was to demonstrate if the Red abalone (Haliotis rufescens) consumes the silage of Brown seaweed (Lessonia trabeculata) under experimental conditions, on the Morro Sama-Tacna FONDEPES aquaculture Centre, during the years 2017 and 2018. We experimented with the control group (fresh seaweed) and two types of silage, treatments: T1 (silage 0% on dry basis) and T2 (silage 35% on dry basis) for 62 days; determining the content of proteins, fats, carbohydrates and energy in the fresh seaweed, no statistically significant difference (p < 0.05) were observed between the treatments, except for the fat content. Treatments, food acceptance was observed during 10 days and food consumption, sizes and weights were estimated with statistic...

La investigación se realizó en los laboratorios de la Escuela Profesional de Ingeniería Pesquera de la Universidad Nacional de Moquegua - sede Ilo, durante el año 2017, en razón de que actualmente a nivel mundial se desarrolla la acuicultura de diferentes tipos de microalgas, sin embargo, en Perú, específicamente en Ilo no se desarrolla este tipo de cultivo por el deficiente conocimiento sobre la tecnología de producción y productividad de microalgas marinas nativas en condiciones controladas, por ello el objetivo fue obtener biomasa de las especies de microalgas Chlorella vulgaris, Tetraselmis estriata, y Nannocloropsis oculata. Los resultados muestran en la fase masiva que la máxima concentración celular fue alcanzada por N. oculata con un promedio de 8.41 x 107 cel/mL y la menor concentración fue de C. vulgaris con un promedio de 1.45 x 106 cel/mL al cuarto día de cultivo...

El propósito del presente trabajo fue determinar el efecto de la aplicación del Programa de Erradicación de Mosca de la Fruta en la Oferta Hortofrutícola Exportable de la región Moquegua, durante el periodo 2004- 2007. Para ello fue necesario establecer, primero, la proporción de producción hortofrutícola regional que fue efectivamente exportada en relación con la producción total, durante el periodo o situación de no erradicación y durante el periodo o situación de erradicación de mosca de la fruta. En segundo lugar, fue necesario comparar las proporciones de producción hortofrutícola exportada correspondientes a ambos periodos. Y tercero, se correlacionan los montos de producción correspondientes a la totalidad del periodo con los años transcurridos, para verificar si existe influencia perceptible entre estos y la producción hortofrutícola exportable. Para efectos d...

La extinción de especies nativas del lago Titicaca resulta uno de los mayores problemas no solo para la salud humana por consumo alimentario, sino además en la subsistencia propia de las especies. El objetivo de esta investigación fue producir alevinos en la especie Orestias luteus mediante reproducción artificial con alimentación natural para su conservación en el lago Titicaca, Puno-Perú. El estudio se realizó durante los meses de febrero hasta noviembre del 2013. Para la conservación, se analizó la fecundación artificial mediante el método seco, así como la producción de cadena alimentaria viva en ambiente controlado. La alimentación consistió en microalgas y microcrustáceos. Las variables controladas fueron la temperatura, pH y oxígeno disuelto. Se obtuvo un porcentaje de fecundación artificial un 92% de ovas fecundadas, 96% de larvas como de alevinos, donde la ali...

El ecosistema acuático como destinatario final de los residuos producidos por los procesos antropogénicos y naturales es un problema creciente de contaminación en nuestro planeta y actualmente la presencia de metales pesados que presentan es un índice alarmante. Esta investigación es importante porque el distrito de Ite utiliza para sus actividades diarias y consumo como líquido elemental el agua del río. La subcuenca del río Locumba se encuentra dentro del distrito de Ite y se caracteriza por actividades mineras y agrícolas. Objetivo:determinar la calidad de los sedimentos del río mediante las concentraciones de metales pesados (As, B, Cd, Cr, Cu, Fe, Mn y Pb) en la zona alta del río Locumba. Materiales y métodos: en los meses de enero y marzo se realizó la toma de muestras en un rango altitudinal entre 350 y 800 msnm, en época seca y lluviosa. Se utilizó la guía para mu...

En la actualidad, la ética profesional constituye el erario conductual en la humanidad, donde no siempre se expresa de forma consciente para su contribución a las investigaciones científicas como aporte al desarrollo social. El objetivo de la presente investigación fue comentar sobre la ética profesional y su concepción responsable para la investigación científica. Para ello, no solo se tuvo en cuenta el significado desde la dimensión antigua, sino además contemporánea. Se indicó la necesidad de reconocer los valores en profesionales, así como los principios y normas que rigen cualquier código de ética profesional. Se concluyó que la ética es una dimensión reflexiva inherente a la formación y al quehacer profesional; ella le permite a la persona no solo comprender el mundo en el que le corresponde actuar, sino también que le ofrece criterios orientadores para entender...

Fishmeal concentrates a high percentage of protein and its monetary cost is relatively high, searching for possible alternatives in macroalgae for improvement purposes is an option. Color is a fundamental characteristic of food, however, drying by the Infrared method as an emerging technology for the study of the macroalga Lessonia trabeculata is little studied. For this reason, the degradation and change of color in the drying process by infrared rays (IR) at different temperatures 40°C, 55°C and 70°C were objectively characterized with the color space scale (CIE-L*a *b*), through the use of a spectrophotometer. Drying was carried out with infrared rays in an infrared radiant heating chamber with a power of 4.5kW, 20.5 Amps. The results indicate that the best color treatment determined was for the macroalga Lessonia trabeculata at a temperature of 40°C with values ​​for: L*= 44....

Obtaining viable Argopecten purpuratus seeds faces challenges, especiallyci the unpredictability of the marine environment and high production costs in hatcheries. However, improving the method of "Broodstock Conditioning In Hatcheries" is key to ensure permanent seed supplies by minimizing the dependence on marine conditions and by maximizing economic viability in hatcheries. In an effort to overcome these barriers, broodstock were conditioned into two different environments: (a) Natural Environment: Natural marine conditions located in Bahía Inglesa, Atacama Region, Chile. (b) Hatchery: Laboratory conditions to achieve gonadal maturation, spawning induction, fertilization and larval development. The purpose of this research was to evaluate how the type of reproductive conditioning affects the reproductive potential and nutritional quality of the progeny. Both methods were successful a...
