“…It has also shown a significant increase of lymphocytes in fish fed vitamin C at an elevated dose for longer periods [20,38]. In contrast to our findings, Menezes et al pointed out that vitamin E supplemented in fish diet reduces the number of total thrombocytes, lymphocytes and neutrophils, and increases eosinophils [39]. They also reported that vitamin C+E and C increase total leukocytes, thrombocytes and eosinophils in pirarucu (Arapaima gigas).…”

White blood cells (WBC) or Leukocytes are defense mechanism indicators in fishes. Vitamins C and E are among the most important nutrients, providing protection to the leukocytes and subsequently influence the fish health and immune system. This study was conducted to investigate the effects of different levels of vitamins C and E (0, 100, 200 and 1000 mg/kg diet) on leukocyte counts of rainbow trout fingerlings during 60 days of feeding trials. The results showed that vitamin E administration increases significantly (P<0.05) the percent of the lymphocytes at 200 and 1000 mg/kg treatments. In addition, a significant increase (P<0.05) was found in lymphocytes of fish fed with 1000 mg/kg vitamin C administration. No significant effects of different levels of Vitamins C and E on neutrophils, eosinophils and monocytes were found during the 60 days experiment (P>0.05). The results revealed that administration of Vitamins C and E can be led to a significant increase in lymphocytes that may influence immune response and resistance against disease.

RESUMENEl objetivo de este estudio fue determinar los valores hematológicos y bioquímicos de juveniles de paiche Arapaima gigas criados en cultivo intensivo. Los juveniles (peso inicial 71,72 ± 23,89 g y longitud inicial 20,45 ± 1,42 cm) fueron estabulados en cuatro tanques de 900 L con recirculación de agua (temperatura 25,90 peces m y posteriormente a 150 peces m . La alimentación se realizó tres veces al día con un alimento ® balanceado (Aquatech , Naltech, Lima, Perú; composición proximal: 42% proteína, 10% lípidos, 12% cenizas; tamaño de partícula: 2,5 y 4 mm). Las muestras de sangre se obtuvieron en cinco muestreos (124, 137, 138, 142 y 143 días) con jeringas descartables conteniendo EDTA al 10% para la determinación de los valores hematológicos y bioquímicos. Al final del experimento, los peces alcanzaron un peso promedio de 832,6 ± 173,1 g y 47,4 ± 2,4 cm de longitud total con una supervivencia de 91,9%. Los valores hematológicos colesterol 104,63 ± 43,89 mg dL . Los valores hematológicos y bioquímicos se encontraron dentro de los rangos reportados para esta especie, mostrando condiciones fisiológicas normales al estar sometidos a condiciones intensivas de cultivo. PALABRAS CLAVE: Amazonia, acuicultura, piscicultura, paiche. HEMATOLOGICAL AND BIOCHEMICAL VALUES FOR Arapaima gigas JUVENILES UNDER INTENSIVE REARING CONDITIONS ABSTRACTThe aim of this study was to determine hematological and biochemical values of juveniles of Arapaima gigas reared in intensive culture. Juveniles (initial wet weight and length: 71,72 ± 23,89 g and 20,45 ± 1,42 cm) were reared in four 900 L tanks with water recirculation (temperature 25,9 ± 0.44 ° C, dissolved oxygen

“…Hence, it could be suggested that any unhealthy condition caused by poor nutrition could affect the hematological characteristics of fish. Plasma glucose concentration is one of the stress indicators in fish (Menezes et al 2006) which may vary greatly depending on the physiological status of the animal (de Andrade et al 2007). Mommsen et al (1999) reported that plasma glucose values can increase, decrease, or keep constant under a high plasma cortisol level.…”

Effects of extruded pellet and moist pellet on growth performance, body composition, and hematology of juvenile olive flounder, Paralichthys olivaceus

et al. 2016

View full text Add to dashboard Cite

A feeding trial was conducted to evaluate the effects of two different sizes of extruded pellets (EP) (EP 1 -3 mm or EP 2 -5 mm) and a moist pellet (MP) in olive flounder, Paralichthys olivaceus, reared in semi-recirculation system. A total of 450 fish with an average initial weight of 5.0 ± 0.2 g (mean ± SD) were fed one of the three experimental diets in triplicate groups. At the end of a 6-week feeding trial, weight gain, specific growth rate, and feed efficiency of fish fed EP diets were significantly higher than those of fish fed MP (P < 0.05). Water quality parameters like turbidity, total ammonia nitrogen, and total phosphorous from tanks of fish fed EP 1 and EP 2 were significantly lower than those from tanks of fish fed MP. Blood plasma glutamic oxaloacetic transaminase and glucose concentration were significantly higher in fish fed MP diet compared to fish fed EP diets (P < 0.05). Whole body crude protein contents in fish fed EP diets were higher than those from the fish fed MP diet. Whole body amino acid content like threonine, aspartic acid, serine, tyrosine, and cystine were found to be significantly higher in fish fed EP diets than those in fish fed MP diet. In considering overall performance of olive flounder, EP 2 diet could be recommended for the successful aquaculture of this important fish species.
