“…The growth trial that was carried out in order to investigate possible anti-nutritional effects did not reveal any negative effect on fish growth and the physiological parameters. The production parameters and somatic indexes considered in our study are comparable with those reported in other studies on gilthead sea bream under experimental conditions (Sanchez-Muros et al 2003;Sadek et al 2004). The absence of differences in the production traits between experimental treatments suggests the possibility of utilising VW in sea bream feed.…”

“…Neither the somatic indexes nor any of the performance parameters studied differed between experimental treatments ( Table 2). Some of the production traits are lower than those reported elsewhere for gilthead sea bream (Sanchez-Muros et al 2003;Gomez-Requeni et al 2004;Sitja-Bobadilla et al 2005), probably due to the extruded fish feed used in these studies. The free radical scavenging activity (DPPH) in the fish fillets (Table 3) was not different between the experimental groups.…”

The aim of the study reported here was to evaluate the efficiency of a natural antioxidant substance in gilthead sea bream (Sparus aurata) feeds. An olive oil by-product, olive mill vegetation water (VW), contains polyphenols, which have a strong antioxidant activity. A 147-day growth trial was conducted (monofactorial balanced, 4 9 3) with diet as the experimental factor. Two diets [isonitrogenous (crude protein 40%) and isoenergetic (gross energy = 18MJ kg -1 on a dry weight basis] were formulated with 1 and 5% of VW (VW1, VW5); the control diet did not contain VW. A total of 600 juvenile gilthead sea breams (mean body weight 114.1 ± 5.7 g) were utilised. Production parameters and somatic indexes were calculated at the end of the growth trial. Antioxidant activity in fish fillets was investigated using TBARS and DPPH assays. A number of haematological parameters and digestive enzyme patterns were measured in fish in the middle and at the end of the experiment. The TBARS values showed slight delays in the development of oxidation in the fillet of fish fed with VW. There was no statistical difference between fish fed with the experimental diet and the control group, except for maltase activity, which increased with increasing VW in the feed. We found that the use of VW in a gilthead sea bream diet did not have any detrimental effects on gilthead sea bream production and physiological parameters and slightly improved the conservation of the fish fillets.

“…Studies have shown that for the adult sea bream feeds the protein content has to be 40-45%, the optimum lipid content has to be 14-22%, and the maximum carbohydrate content 20% (Gomez-Requeni et al 2003, Sanchez-Muros et al 2003, Teles et al 2011. The results of the proximate composition of feeds used in our study were appropriate for sea bream and agree with the aforementioned studies.…”

SUMMARY: This study aimed to develop a better understanding of organic sea bream aquaculture production in Greece, in particular its consequences for fish growth, health and body composition, and to propose and update standards for sustainable organic sea bream farming. Gilthead sea bream were kept in sea cages at densities of 4 kg m -3 (organic) and 15 kg m -3 (conventional), and were fed organically produced feed (45% crude protein, 14% fat) or conventional feed (46% crude protein, 17% fat). The amino acid profile of the conventional diet, particularly the lysine content, which is one of most important dietary amino acids for sea bream, appeared to be unsatisfactory. "Organic" sea bream stored less fat content in their white muscle than the conventional sea bream. The liver lipid content was lower and the hepatosomatic index was higher for the organic sea bream. The microbiological analysis showed that both Enterobacteriaceae and Escherichia coli on the skin were below the enumeration detection limit in both the organic and conventional sea bream. Total viable counts on the skin and muscle of both the organically and conventionally cultured sea bream were approximately 3 log cfu g -1 , which is well below the acceptable limit (7 log cfu g -1 ) for marine species. The results showed that the combination of a low stocking density and feed with a different ingredient composition but similar nutritional value resulted in similar growth rates and nutrient profiles of the final product. Further research on nutrition is required to provide information on setting the appropriate standards for organic sea bream aquaculture to ensure that the final product is in line with the consumers' preferences.Keywords: sustainable, organic, sea bream aquaculture. RESUMEN: EfEcto dE los métodos dE producción orgánica y convEncional En El crEcimiEnto, salud y composición corporal dEl pargo: un ExpErimEnto dE campo. -Este estudio tiene por objeto desarrollar una mejor comprensión de la producción acuícola orgánica del pargo en Grecia, en particular sus consecuencias en relación al crecimiento del pez, su salud y su composición corporal, y proponer y actualizar los estándares para la cría sostenible y orgánica. Los pargos dorados fueron criados en contenedores con densidades de 4 kg m -3 (orgánico) y de 15 kg m -3 (convencional) y les fue ofrecido alimento producido orgánicamente (45% de proteina cruda, 14% de grasa) y convencionalmente (46% de proteina cruda, 17% de grasa). El perfil de los aminoácidos de la dieta convencional, en especial en relación al contenido en lisina, uno de los aminoácidos alimentarios más importantes para pargos, pareció ser insatisfactorio. Los pargos "orgánicos" acumularon una menor cantidad de grasa en sus músculos blancos en compración con los pargos convencionales; el contenido en lípidos del hígado es menor y el índice hepatosomático es más alto en los pargos orgánicos. Los análisis microbiológicos muestran que las Enterobacteriaceae y las Escherichia coli en la piel estaban por debajo del límite de de...

“…Yilmaz et al (2005) pointed out that diets with soy-acid oil lowered daily feed intake of common carp compared to fish fed diet with no soy-acid oil. Sanchez-Muros et al (2003) has also determined that soy-protein diet lowered daily feed intake of fish compared to fishmeal protein-based diet. The lower feed intake of high energetic diets has also been shown in some other cultured fish species (Keembiyehetty and Wilson 1998;Hernandez et al 2001).…”

The objective of this study was to investigate the effects of five isonitrogenous (35% crude protein) diets having different energy contents; 10. 85, 11.82, 12.73, 13.69, and 15.06 MJ DE/kg, respectively, on the gonad development and weight gain of Sharptooth catfish fingerlings. Energy contents of the experimental diets were increased with the increasing amount of soy-acid oil (0, 4, 8.5, 13, 18%) and each group of fish was fed on their respective diets (group I was fed diet I) during 180 days. The gonad maturation was significantly affected by dietary energy. In both sexes, the histological inspections of the gonads did reveal differences among the fish fed different energetic diets. Fish fed diets I, II, and III had significantly heavier and more developed gonads compared to those on diets IV and V. Fish fed the higher energetic diets (IV and V) had partially low numbers of yolky oocytes compared to other groups. The mean GSI values of female and male fish fed with diet III was significantly greater than those fed diets with higher dietary energy; however, higher HSI values were recorded for fish fed with the higher energetic diets (IV and V). Also, the best weight gain for both males and females were recorded from the fish fed diet III (12.73 MJ DE/kg). Therefore, on the basis of the present results, among energy levels tested, 12.73 MJ DE/kg was found to be optimal for healthy gonad development and weight gain.
