The objective of this study was to evaluate the effects of vitamin C on growth and quality of semen from Oreochromis niloticus breeders. One hundred and sixty males were fed with different levels of vitamin C (0, 261, 599 and 942 mg/kg diet). The higher weight values were recorded for 599 (166 g) and 942 (175 g) mg of vitamin C/kg diet. Sperm motility, vigour and concentration were higher with 599 and 942 mg of vitamin C/kg diet. The semen volume, gonadosomatic index and plasma protein data from the last week showed a direct relationship with increasing levels of vitamin C. No changes were observed in the hepatosomatic index and blood glucose. The haematocrit and erythrocyte showed higher values estimated by equations derived at 850 and 638 mg vitamin C/kg diet, respectively. The leucocytes were inversely proportional to the increasing levels of vitamin C. After 100 days of feeding, animals fed the diet containing 942 mg vitamin C/kg diet had higher sperm motility, linearity, curvilinear velocity, straight line velocity and average path velocity (p < .05). Higher values of beat cross-frequency were observed in broodfish fed diets containing 942 and 599 mg vitamin C/kg. The different vitamin C levels did not cause differences in straightness, lateral head displacement and sperm morphology. For Nile tilapia males on intensive rearing and handling conditions, vitamin C levels between 599 and 942 mg/kg may be used for a better performance and quality of semen.

“…Observaciones similares han sido reportadas en Micropterus salmoides (3), Paralichthys olivaceus (4), Oreochromis niloticus (5,18), Arapaima gigas (6), Salmo trutta caspius (7), Rachycentron canadum (19), Megalobrama amblycephala (20), Brycon amazonicus (21,22), Colossoma macropomum (23), Oncorhynchus mykiss (24,25), Rhamdia quelen (26), Rhizoprionodon terraenovae (27), Sparus aurata (28) y Cyprinus carpio (16,29), entre otras. No obstante, según Salinas et al (30), no existe ningún efecto al suplementar la dieta con AA en Polyprion oxygeneios (30) ni en Oreochromis niloticus (31). Como se pudo observar en la figura 1, los resultados mostraron que cuando los peces son alimentados con dieta sin contenido de AA, presentan un pico de producción de cortisol más alto que los peces alimentados con dieta que contiene vitamina C. Resultados similares fueron reportados en Arapaima gigas (6) y Megalobrama amblycephala (20).…”

Juveniles de Piaractus brachypomus (30 ± 4,76g) fueron alimentados ad libitum durante 30 d con una dieta de 32 % de proteína, suplementada con seis cantidades diferentes de ácido ascórbico (AA): T1 = 0 mg/kg; T2 = 100 mg/kg; T3 = 200 mg/kg; T4 = 400 mg/kg; T5 = 800 mg/kg; T6 = 1600 mg/kg. Finalizada la fase de alimentación, los animales estuvieron en exposición aérea durante 60 s y luego se devolvieron al agua. Se colectó sangre mediante punción en la vena caudal de tres individuos por tratamiento a los 5; 30; 60 y 360 min después de haber sido devueltos al agua. Con estas muestras se determinaron en plasma las concentraciones de cortisol, glucosa, lactato y proteínas totales. En suero, se midió la concentración de los iones Cl– y Na+. Finalmente se calculó la sobrevivencia. Los datos fueron sometidos a un análisis de varianza ANAVA, y cuando se encontraron diferencias, las medias se compararon mediante prueba de Tukey (α = 0,05). El cortisol presentó el pico más alto en los ejemplares alimentados con la dieta libre de AA. Las concentraciones de glucosa fueron menores en los peces suplementados con 400 mg/kg a los 5, 30 y 60 min. Las concentraciones de los dos iones se mantuvieron estables a través del tiempo en los ejemplares suplementados con 200 mg/kg. La supervivencia fue de 100 % en todos los tratamientos. La suplementación con concentraciones entre 100 y 400 mg/kg AA mejoró la respuesta de los animales ante el estrés por hipoxia.

“…At the end of the experiment, after 24-hour fasting, the fish were collected, desensitized in 250 mg L Eugenol -1 , slaughtered then measured the total length and standard, final weight stored in plastic bags to be frozen for further analyzes of the whole fish bromatological. The fish were ground and dried and then used from each replicate for dry matter analysis, ethereal extract and crude protein according to (Navarro et al, 2010).…”

This study aims to evaluate the effect of different initial densities of Nile tilapia fingerlings on water quality, fish growth, and production of marjoram (Origanum majorana L.) and sweet basil (Ocimum basilicum L.) in a recirculating aquaponic set up. The experiment was carried out on randomized block design and comprised four fish densities (0, 150, 250 and 500 fish m-3) and two crops, in which each treatment was continued for 45 days and replicated three times. Except for pH and total alkalinity, all water physicochemical parameters were increased significantly at high fish densities. In contrast, most of the biological parameters for fish were unaffected by culture density, although at the highest density crude protein percentage was significantly increased and ether extract percentage was significantly reduced. Plant productivities were highest when fish were cultured at density of 500 fish m-3 , a density that was found to be appropriate for maintaining water quality and promoting fish growth while preventing toxicity and mortality. The present study has demonstrated the technical viability of coupling Nile tilapia culture coup with aquaponic production of marjoram and sweet basil.
