“…Resultados semelhantes foram constatados em relação à truta arco-íris, carpa indiana (Cirrhina mrigala), bagre de canal, pacu, acará-açu e Clarias gariepinus (Agrawal & Mahajan, 1980;Martins et al, 1995;Fracalossi et al, 1998;Li & Robinson, 1999;Adham et al, 2000). Por sua vez, não foram observadas alterações nos valores de hematócrito e RBC com suplementação com ácido L-ascórbico de 100 e 500 mg/kg.…”

“…Essas variáveis do sangue periférico sugerem uma condição anêmi-ca com tendência normocrômica/normocítica. Os incrementos nos valores de VCM verificados nos tambaquis alimentados sem ácido L-ascórbico são semelhantes aos relatados em relação à carpa indiana (Agrawal & Mahajan, 1980), e os incrementos observados nos valores de HCM e CHCM são similares aos relatados com o pacu do Pantanal . Desta forma, as alterações fisiológicas observadas neste trabalho, refletidas em alguns ín-dices hematológicos, são importantes indicadores de deficiências alimentares bem como de mudanças na Tabela 3.…”

Resumo -O objetivo deste trabalho foi avaliar o efeito da suplementação dietária com ácido L-ascórbico (vitamina C) no ganho de peso e em parâmetros hematológicos de juvenis de tambaqui, Colossoma macropomum. Após dez semanas, em que foram alimentados com dietas contendo 0, 100 e 500 mg de ácido L-ascórbico por kg de ração, os peixes foram capturados e imediatamente anestesiados para a coleta de sangue da veia caudal e determinação dos parâmetros hematológicos. Animais alimentados com maiores níveis de ascorbato mostraram pesos corpóreos maiores, melhores taxas de conversão alimentar e sobrevivência. A asência de ácido L-ascórbico na ração, além de causar redução nos valores de hematócrito e no número de eritrócitos, que caracteriza anemia, provocou aumento no volume corpuscular médio, na hemoglobina corpuscular média e na concentração de hemoglobina corpuscular média. Esses resultados revelam a importância do ácido L-ascórbico na dieta dos juvenis de tambaqui. O nível de 100 mg de ácido L-ascórbico/kg de ração é adequado, garantindo bom ganho de peso e manutenção da homeostase do organismo.Termos para indexação: Colossoma macropomum, suplemento alimentar, nutrição animal, piscicultura. Effect of vitamin C on weight and hematology of tambaquiAbstract -The objective of this work was to estimate the effect of L-ascorbic acid (vitamin C) dietary supplementation on the body weight and on the hematology of juveniles tambaqui, Colossoma macropomum. After ten weeks receiving diets containing 0, 100 and 500 mg of L-ascorbic acid per kg of food, the fish were netted from the tanks, immediately anesthetized and blood was withdrawn from caudal vein for analysis of hematological parameters. Animals fed on higher ascorbate levels showed higher final body weight, better feed conversion rate and survival. Also, the L-ascorbic acid free-diet resulted in reduction of hematocrit and red blood cell count, characterizing anemia, and an increase of mean cell volume, mean cellular hemoglobin and mean cellular hemoglobin concentration. These results show the importance of L-ascorbic acid supplementation in the diet of juveniles tambaqui. The level of 100 mg of L-ascorbic acid/kg diet is adequate, guaranteeing better body weight gain and maintenance of organic homeostasis.

Vitamins are organic compounds that can be synthesized from other essential nutrients; however, they are required in trace amounts from an exogenous source for normal growth, reproduction and health. Vitamin C (ascorbic acid, AA) is an essential micronutrient for normal growth and physiological function of most aquatic animals. In terrestrial animal nutrition, vitamin C has recently spurred scientific interest because of the increasing knowledge on vitamin C involvement in gene expression, cell cycle and reproduction in mammals; in addition, recent advances in molecular biology techniques allow the more effective estimation of the effect of vitamin C on metabolism and physiology. In contrast, this information is scarce in aquatic animal nutrition, as studies have essentially focused on the estimation of minimum vitamin C requirement for maximum growth and immune response as well as for the formulation of least‐cost diet. This scarcity of information is also due to the lack of well‐established indicators of vitamin C status in aquatic organisms. The present review summarizes and discusses information about vitamin C sources, bioavailability, deficiency and requirement in aquatic animals to plan further studies. In the future, vitamin C nutrition studies in aquaculture should also include immune responses, histopathology of the gills, liver, gonad development, gamete quality and quantity, fecundity, larvae survival and gene expression. Dietary vitamin C requirements should be estimated at every life‐history stage of cultured species. All this information will allow a better understanding of the essentiality of vitamin C in aquatic animal growth, development, reproduction and health.

Pyridoxine defieiency was experimentally produced in a population of Channa punctatus Bloch by feeding a pyridoxine deficient vitamin test diet for 240 days. The deficiency effects were further accentuated in another group of fish by adding 4-deoxypyridoxine as an antagonist to the deficient diet. The behaviour, general morphology and growth of these fish were compared with control fish maintained on a complete vitamin test diet. The behavioural study revealed a series of nervous disorders such as ataxia, hyperirritability and muscular spasm followed by convulsions, fits, anorexia and paralysis in the posterior region during advanced stages of the deficiency. Gross morphological changes recorded were retarded growth and loss of weight resulting in a pinhead condition; integumentary damage such as scale loss, leakage of oedematous fluid and abnormal pigmentation, opacity of the lens resulting in eomplete blindness and enlargement and nodule formation in the spleen and kidney. Reeovery treatment for 30 days comprising restoration of dietary supply of pyridoxine supplemented by intramuscular injections brought about considerable recovery in the fish with dietary pyridoxine defieiency but the antagonist-treated deficient group showed little recovery, although further deterioration was halted.
