“…In fish also it is assumed that vitamin C is an essential nutrient for optimum growth and maintenance (Dupee 1966;Halver et al 1969;Lovell 1973;Mazik et al 1987). With the exception of, perhaps, two or three species, vitamin C biosynthesis does not occur in fish due to the lack of the last enzyme of the biosynthetic pathway-L-gulonolactone oxidase.…”

“…Channel catfish (Ictalurus punctatus) fed vitamin C deficient diets were susceptible to ammonia toxicity and low dissolved oxygen concentrations (Mazik et al, 1987), while seabream (Sparus aurata) fed ascorbic acid free diet presented significant hyperglycemia and a wider variation of the plasma cortisol level when submitted to a 24-hour hypoxia (Henrique et al, 1998).…”

The role of vitamin C on physiological responses of matrinxã (Brycon amazonicus) submitted to air exposure was analyzed. Nine hundred fish (70.15 g) were distributed in fifteen 500 l boxes (60 fish.box -1 ) and fed five rations (treatments): Control (no vitamin C); T100 (100 mg); T200 (200 mg); T400 (400 mg) and T800 (800 mg of vitamin C kg.ration -1 ). Each ration was offered to fish of three boxes during 60 days before the stress challenge that consisted of exposing fish to air for two minutes. Samplings were carried out for 5, 15, 30 and 60 minutes after the air exposure. Blood was collected for glucose, cortisol, total protein, sodium, chloride, hematocrit, hemoglobin determination, and white and red cell count. Liver was removed for hepatosomatic index (HSI) calculation and glycogen determination. Vitamin C did not affect the levels of cortisol, chloride, total protein, hemoglobin, leukocytes, hepatic glycogen or HSI in air exposed fish. Blood glucose levels elevation observed 60 minutes after the challenge did not depend on the levels of vitamin C, nor did the drop in serum sodium levels verified 60 minutes after stressor. In general, hematocrit did not change by effect of vitamin C but it was lower at 15 and 30 minutes after the challenge. The number of erythrocytes decreased in fish after 5 minute sampling in all treatments, especially at 30 and 60 minutes. The air exposure evoked alterations in stress indicators of matrinxã, and the vitamin C did not alter the responses.

Novecentos peixes (70,15g) foram distribuídos em caixas de cimento (500 l) e alimentados com os tratamentos: Controle (sem vitamina C); T100 (100 mg); T200 (200 mg); T400 (400 mg); T800 (800 mg de vitamina C kg.ração -1 ). Cada ração foi fornecida a peixes de três caixas por 60 dias antes da aplicação do estressor, que consistiu em suspender os peixes mantendo-os no ar por dois minutos. Cinco, 15, 30 e 60 minutos depois, os peixes anestesiados foram amostrados. Foi coletado sangue para determinação PALAVRAS -CHAVEBrycon amazonicus, captura, estresse, ascorbil polifosfato.

This study aimed to evaluate the influence propolis extract inclusion to the feed mixture for juvenile angelfish (Pterophyllum scalare) on larval performance and transport. Levels of propolis extract inclusion consisted of 0, 300, 600, 900, and 1200 mg.kg -1 of feed. After 14 days of hatching, unmetamorphosed larvae with a total length of 18.4 mm and 0.11 g initial weight were used. Six-hundred larvae were divided into 20 experimental units, totalizing 30 larvae each. Experimental units consisted of polythene containers with independent water input and output and a level controller. Each unit was controlled for maintenance of 40 L water within a recirculation system. After offering feed containing propolis extract, five fish from each experimental unit were packed in bags for transportation only with atmospheric air, without pure oxygen addition. The bags were filled with 300 mL water on a 2:1 basis of air and water respectively. The total transport time was considered until the death of the third fish in package. At the end of the experiment, data underwent statistical analysis through Statistical Analysis System (SAS, 2001). Results showed there was no significant difference (P<0.05) neither for any of the studied zootechnical variables (standard length, total length, height, and weight) nor for the transport of juveniles. In conclusion, propolis extract addition to angelfish feed was ineffective for larval performance and for transportation of juveniles, at the levels tested here.
