Dietary administration of probiotic Pdp11 promotes growth and improves stress tolerance to high stocking density in gilthead seabream Sparus auratus

摘要: Abstract The effects of dietary administration probiotic Pdp11, a bacterial strain from the Alteromonadaceae family, on growth and stress tolerance to high stocking density was analyzed in juvenile gilthead sea bream Sparus auratus . In first trial, specimens were fed during 116 days with control feed or diets supplemented growth, serum immunological parameters as well plasmatic, hepatic muscular metabolic assessed. Growth performance improved group receiving compared group. No differences observed for assessed parameters. second both groups experiment submitted following conditions 15 days: i) food either under low (3 kg/m 3 ), (30 kg/m ) ii) density, density. Our results indicated that Pdp11 diet promoted suggesting its use will be beneficial aquaculture industry this species.
