“…The dominance of diatoms and cyanobacteria to a lesser extent, on periphyton, coincides with observations by other authors (Thompson et al 2002;Ballester et al 2007;Khatoon et al 2007a;Anand et al 2013). The presence of euglenophytes, prasinophytes and prymnesiophytes in the periphyton has not been reported in most previous studies on aquaculture (Ballester et al 2007;Kahoon et al 2007a;Anand et al 2013;Betancur-González et al 2016). However, these studies analyzed periphyton composition by optic microscopy.…”

“…However, these studies analyzed periphyton composition by optic microscopy. In phytoplankton studies, carried out with optical microscopy, a large presence of these three groups is not reported either (Ballester et al 2007;Kahoon et al 2007a;Anand et al 2013;Sruthisree et al 2015;Betancur-González et al 2016). On the other hand, the analysis of photosynthetic pigments by HPLC in aquaculture tanks has allowed to report the presence of these groups in phytoplankton (Jiang et al 2016;Lemonnier et al 2016;and Llario et al 2018).…”

Microalgae play a fundamental role in aquaculture systems, especially in nurseries. They can supplement the nutrition of cultured species, and also contribute to keep good water quality. Their value depends on the groups present in major abundance. Thus, being able to understand the factors that influence microalgae composition is key for an improved system management. In this study, the microalgae community structure in a Marsupenaeus japonicus nursery is studied. Instead of the classic microscopy approach, the composition and abundance of periphyton and phytoplankton were analyzed using signature pigments analysis by high pressure liquid chromatography coupled with the software CHEMTAX. The environmental parameters, which could affect periphyton and phytoplankton groups, were analyzed statistically. The results showed that diatoms were the dominant group both in phytoplankton and periphyton. The analysis of signature pigments, allowed to report the presence of previously undetected groups on periphyton, prasinophytes and prymnesiophytes, which are characterized by a high nutritional value. This is especially important in nurseries because of shrimp grazing on periphyton can increase post-larvae survival. Nutrients played a key role on phytoplankton development, but had a minor effect on periphyton, which was more affected by colonization processes and other environmental variables.

“…La composición de las comunidades planctónicas, asociadas al cultivo de tilapia roja (Oreochromis sp) en tecnología biofloc, se basó en tres grupos planctónicos (sin incluir bacterias) asociados a los flóculos, como son microalgas, rotíferos y protista; siendo microorganismos importantes a nivel biológico y nutricional [39]. Los resultados obtenidos concuerdan con literatura cuyo propósito fue caracterizar las comunidades planctónicas durante el desarrollo de cultivos con esta tecnología [40], [41], entre los cuales se encontraron los géneros Oscillatoria, Diatomea y Closterium que son considerados como bioindicadores de la presencia de amonio y nitritos en el sistema BFT [42], [43], que ya se han descrito son compuestos propios del sistema productivo y de cuidado por la toxicidad que generan para los peces, así mismo es de importante resaltar que las proliferaciones o crecimientos algales suelen ocurrir en aguas eutróficas o ricas en nutrientes (particularmente fosfatos, nitratos y amoniaco) con temperaturas entre 15 a 30 °C y donde el pH oscila entre 6 y 9, pero deben estar bajo vigilancia para recambio o filtrado porque en grandes concentraciones estos individuos llegan a ser tóxicas [42], y se encontró algunos rotíferos que en el sistema BFT pueden llegar a controlar las poblaciones microalgales.…”

La pandemia por COVID-19 no ha acabado. Aún hoy, a poco más de dos años de su inicio, sigue siendo un fenómeno impredecible que ha suscitado múltiples aristas de interés a partir de las líneas de investigación tradiciones. Nosotros, desde la Corporación Universitaria Autónoma de Nariño AUNAR Cali (Colombia), hemos evidenciado el interés en socializar, compartir, reflexionar y construir a partir de estas nuevas dinámicas de trabajo en el quehacer investigativo. Por ello, por segundo año consecutivo a finales del 2021 organizamos el II Congreso Internacional de Ciencias Económicas y Sociales. III Encuentro de Socialización Académica sobre Experiencia Investigativas para generar ese espacio de comunión entre investigadores de distintas instituciones y países a nivel mundial unidos con un mismo fin: aportar innovaciones científico-tecnológicas al avance de la investigación y la innovación. En este tercer tomo del libro Avances en investigación científica se recogen los trabajos presentados en el mencionado evento como una estrategia de apropiación social y difusión del conocimiento libre y abierto. Esta edición, a partir de las ciencias multidisciplinarias, condensa trabajos en las áreas de cultura y sociología, economía y gestión organizacional, estrategias y prácticas educativas, medio ambiente y sostenibilidad, y políticas públicas.

“…In the biofloc, there are conditions for another series of organisms of that trophic network that makes it up to prosper, such as ciliates, microalgae, copepods, rotifers and cladocerans (Ayazo-Genes et al, 2019;Betancur et al, 2016;Hernández et al, 2017;Monroy-Dosta et al, 2013). Consequently, all the ions, nutrients, microorganisms, planktonic communities, organic and inorganic matter that make up the biofloc also serve as food for the cultured fish species, in a true concept of in situ nutrient recycling (Avnimelech, 2009).…”

This work evaluated the effects of different carbon/nitrogen (C/N) ratios in the larvae and fry culture of Piaractus orinoquensis in biofloc system on the water quality, proximate analysis and growth performance. The experiment was conducted in two stages: (a) larval stage from 0 to 12 days post stocking (DPS) and (b) fry stage from 13 to 24 DPS, at a density of 10 larvae/L. Three groups of C/N ratios were evaluated as follows: T1: 10/1 ratio, T2: 15/1 ratio and T3: 20/1 ratio, each treatment with three replicates. Both in the larval and fry culture, total ammonia nitrogen (TAN) and nitrite were higher in the T2 and T3 treatments, while the nitrogen removal in T1 treatment was more efficient, resulting less TAN, nitrite and higher nitrate. However, the water quality parameters in all treatments were within the appropriate ranges for fish culture in biofloc. T2 treatment was nutritionally better, presenting higher levels of protein, lipids and energy. In both stages, P. orinoquensis survival and final weight were significantly higher in the T2 treatment. In conclusion, P. orinoquensis larvae and fry culture in biofloc is viable, improving the survival and growth at a C/N ratio of 15/1.
