“…El registro del peso y crecimiento de los peces se llevó mediante un libro de campo (bitácora) para elaborar la base de datos, procesarlos estadísticamente y expresarlos en los Después de 55 días de ingesta de alimentos de los juveniles, se dejaron en inanición 14 horas antes de tomar muestras de sangre, para ello los juveniles se anestesiarán con solución de eugenol: alcohol (relación 1:3 mL en 10 L de agua), durante 2 min. Las muestras de sangre se obtuvieron según lo indicado por Azizoglu and Cengizler (1996), por venopunción caudal con jeringas desechables de 3 mL y depositada en tubos vacutenier (Vacuette, Laborgeräte GmbH, Eschau, DE), y se conservaron en refrigeración a 4 °C por 24 h. Luego se centrifugaron (Gemmy, PLC-05, Taipei, TW) a 1200 rpm durante 10 min para separar el plasma de los elementos formes.…”

El uso de bioestimulantes en dietas para peces es de gran interés actualmente. Se evaluó la respuesta inmune y bioquímica en juveniles de tilapia roja (Oreochromis mossambicus x O. niloticus), con diferentes niveles: 0 (control), 1, 2, 3, 4 y 5% de suplementación de quitosano en dieta. Se sembraron inicialmente 270 animales, con un peso promedio de 7.53 ± 0.50 g, distribuidos en un diseño completamente al azar, en 18 tanques=réplicas (tres réplicas/tratamiento). Se realizó un análisis de varianza y una prueba de medias con LSD de Fisher. Los juveniles se alimentaron durante 55 días y se tomaron muestras de sangre a los 56. Se encontró una mejor respuesta en el crecimiento (TCE = 15.2), aprovechamiento del alimento (FCA = 0.76) y supervivencia (SP =100%) cuando se le alimenta 4% de quitosano en dieta (p < 0.05). Los resultados bioproductivos más bajos fueron encontrados en tratamiento control (0% de quitosano). Con respecto a las variables: contenido de leucocitos y actividad antioxidante se encontró mejor respuesta significativamente (p < 0,05) cuando se incluye quitosano en un 3 y 4 % en dieta. Se concluyó que la respuesta bioquímica e inmune juveniles de tilapia roja se favoreció con la inclusión de quitosano en dieta.

“…At the end of the culture period, they were fasted for 14 h before taking the samples. Blood samples were obtained as indicated by Azizoglu and Cengizler (1996), by caudal venipuncture with 1 mL disposable syringes and deposited in vacutenier tubes (Vacuette, Laborgeräte GmbH, Eschau, DE) and they were kept refrigerated at 4 °C for 24 h. They were then centrifuged (Gemmy, PLC-05, Taipei, TW) at 1200 rpm for 10 min to separate the plasma from the formed elements (Méndez-Martínez et al, 2022).…”

The aquaculture due to the high cost and continued shortage of animal protein sources, the development of alternative plant protein sources has been one of the main challenges to establish sustainable aquaculture as economically viable. Objective of this investigation was to determine the chemical composition and effect of Tithonia diversifolia on the growth performance, feed efficiency and metabolic biochemistry of juveniles of Oreochromis mossambicus × Oreochromis niloticus. Five treatments were used: 0% (control), 4, 8, 12 and 16% levels of inclusion of T. diversifolia flour in diet to feed juvenile fish cultured in 15 plastic aquariums at a density of 15 fish/aquarium. The assay lasted eight weeks. The T. diversifolia flour was characterized for showing adequate levels of crude protein (21%), with low crude fat (4.5%) levels, neutral detergent fiber levels: 43.03% and acid detergent fiber: 24.40%. The growth performance presented significant differences (p˂0.05), for weight gain, day average weight gain (DAW), length gain, day average length gain (DAL), specific growth rate (SGR), feed efficiency (FE), protein efficiency ratio (PER) and feed conversion ratio (FCR). In treatment with 16% of inclusion of T. diversifolia flour, values obtained for weight gain, DAW, SGR, FE and PER (15.88 g, 0.28 g. day-1, 2.03 %, 0.34 g.g-1 and 0.98, respectively), which did not differ with the control treatment, highlighting the benefits of T diversifolia flour. The metabolic biochemistry parameters experienced a decrease with the increase of T. diversifolia in diet, where the highest values of triglycerides, cholesterol, and glucose were for the control treatment (p <0.05), while the protein increased to 4% of the flour. T. diversifolia flour presents an adequate balance of nutrients for its chemical composition and amino acids, without causing negative effects on the growth performance, weight-length relationship, feed efficiency, survival and metabolic biochemistry.

This study was carried out to understand the preventive effect of selenium (Se4+) on heavy metal stress induced by lead and copper in rainbow trout (Oncorhynchus mykiss). Variation in glutathione peroxidase (Se-GSH-Px) and superoxide dismutase (SOD) activity, and in malondialdehyde (MDA) levels in liver, spleen, heart, and brain tissues of rainbow trout after 72 h of exposure to Pb2+ and Cu2+ were investigated in the presence and absence of Se4+. In the presence of Se4+, Se-GSH-Px activity and SOD activity were found to be higher and MDA levels were lower compared with in its absence. Hematological parameters were also determined and it has been observed that total leukocyte count (WBC), mean cell volume (MCV), and mean cell hemoglobin (MCH) were increased and erythrocyte number (RBC), hemoglobin (Hb), and hematocrit value (Hct; P < 0.05) were decreased in fish exposed to heavy metals in the absence of selenium. Selenium presence recovered hematological parameters to normal levels. In the light of our findings, it could be stated that Pb2+ and Cu2+ lead to dramatic changes in biochemical and hematological parameters and selenium caused these parameters to converge to control levels when it was administered concurrently with these heavy metals.
