“…For instance, similar growth rates were found in Powan Coregonus lavaretus and Matrinxã Brycon amazonicus (Känkänen and Pirhonen 2009;Urbinati et al 2014) that were fed on five or seven consecutive days, but the growth of fingerling Dusky Grouper Epinephelus marginatus and Pirapitinga Piaractus brachypomus was significantly reduced by 2-d starvation periods (Favero et al 2021;Spandri et al 2021). Differences in the length of the experiments, the size of the experimental cohorts, and daily feeding frequency may have contributed to the observed differences.…”

“…At the end of the present study, it was found that fasting and resupplying had no notable effects on the hematological characteristics of juvenile S. scherzeri , and similar results were found with the Siberian sturgeon ( Acipenser baerii ) [ 15 ], Nile tilapia [ 66 ], olive flounder ( Paralichthys olivaceus ) [ 67 ], European eel ( Anguilla anguilla ) [ 68 ], red porgy ( Pagrus pagrus ) [ 69 ], and beluga ( Huso huso ) [ 70 ]. During the present study, it was observed that fasting influenced GLU and TCHO levels in the plasma of juvenile S. scherzeri ; however, no such increase in plasma GLU was observed in sea bass ( Dicentraachus labrax ) [ 71 ] or pirapitinga ( Piaractus brachypomus ) [ 72 ]. Cholesterol is a structural lipid utilized or synthesized in response to feed deprivation; however, it is also maintained during feed deprivation without increasing, decreasing, or changing depending on the species and fasting duration [ 72 ].…”

For the present study, the cholesterol concentrations decreased after fasting (week 2), similar to the results observed for rainbow trout [ 73 ], brown trout ( Salmo trutta ) [ 74 ] and sturgeon ( Acipenser naccarii ) [ 75 ].…”

“…En la piscicultura, una opción factible es criar peces en un sistema de recirculación de agua (RAS por sus siglas en inglés)(Vásquez Gamboa, 2013).Los RAS son sistemas intensivos altamente productivos, ecológicos y eficientes en el uso del agua, que no están asociados con impactos ambientales adversos, como la destrucción del hábitat, la contaminación del agua y la eutrofización, el agotamiento biótico, los efectos ecológicos en la biodiversidad debido al escape de peces en cautiverio y especies exóticas, brotes de enfermedades y transmisión de parásitos(Ahmed & Turchini, 2021).En la revisión bibliográficade Sousa et al (2020) determinaron la mejor densidad de población de juveniles de tambatinga (Colossoma macropomum × Piaractus brachypomus) en un sistema de recirculación durante 50 días de cultivo, ellos evaluaron densidades de 5, 10 y 15 peces/tanque. La menor densidad (5 peces/tanque) mostró mayor ganancia de peso y tasa de crecimiento específico, mientras que en la densidad de 10 peces/tanque mostró una alta deposición de lípidos en el canal, así, la densidad de 5 peces/tanque (0,08 m), resultó la más adecuada.Otro estudio fue elde Favero et al (2021) quienes evaluaron el crecimiento y fisiología de juveniles de Colossoma macropomum en tres fases durante 153 días, con diferentes densidades de acuerdo a su peso bajo RAS y concluyen que, los peces presentan adaptación al sistema con buenos resultados para rendimiento zootécnico; las densidades más altas producen mayor biomasa; la clasificación de los peces debe ser una estrategia de manejo importante para mantener la uniformidad, ya que diferentes densidades y tamaños de peces pueden interferir en algunos parámetros hematológicos y bioquímicos, y pueden usarse como indicadores del bienestar animal.Bajo este método, la piscicultura se realiza en un sistema cerrado o semicerrado, reutilizando el agua después de un tratamiento biológico y mecánico, con el fin de reducir la eliminación de residuos y el consumo de agua(Valenzuela Vargas et al, 2017). De esta forma, el agua del cultivo…”
