“…This species is suitable for aquaculture because of its fast growth, easy reproduction and high tolerance to adverse environmental conditions [10]. Therefore, further identification of commercially available dietary additives to improve performance and disease resistance of these fish is still highly desired.…”

The effect of dietary mannan oligosaccharide (MOS; activeMOS®) on growth, survival, and body composition in giant sturgeon juvenile (Huso huso) with initially average weight 46.89 ± 2.57 was investigated for a period of 46 days. Basal diet were supplemented with 0 (control), 2, and 4 g kg(-1) MOS in a totally randomized design trial in triplicate groups. The results showed no significant differences in growth and feeding parameters between control and treatment groups (MOS supplementation diets) (P > 0.05). There was a statistically significant decrease (P < 0.05) in feed per fish level in only group treated with 4 g kg(-1) MOS. The highest and the lowest growth performances were observed in 2 and 4 g kg(-1) MOS, respectively. There were no significant differences in survival rate among all treatment groups (P > 0.05). In group treated with 2 g kg(-1) MOS was a significant difference in lipid carcass (P < 0.05), whereas protein, ash, and moisture remained unaffected (P > 0.05). However, no significant difference was observed in intestinal lactic acid bacteria between all treatment groups (P > 0.05). There were no significant differences in hematological parameters between control and MOS treatment groups (P > 0.05). These results suggested that the prebiotic mannan oligosaccharide did not influence the growth performance in giant sturgeon juvenile, and it is not appropriate for supplementation in the diet of cultured juvenile giant sturgeon.

“…It has also been shown that carnitine can reduce lipid content of muscle in sea bass (Santulli and D'Amelio, 1986b) and seabream (Sparus macrocephalus) (Ma et al, 2008). In addition, Mohseni et al (2008) showed that growth performance of sturgeon (Beluga beluga) was improved when fish was fed 300 mg L-carnitine kg -1 diet. Nevertheless, little or no effect of L-carnitine supplementation on growth was observed in other species (Burtle and Liu, 1994;Ji et al, 1996;Chatzifotis et al, 1997;Harpaz et al, 1999;Gaylord and Gatlin, 2000;Dzikowski et al, 2001;Ozório et al, 2001;Schlechtriem et al, 2004).…”

Commercial farming of turbot (Scophthalmus maximus) at high stocking densities may lead to growth depression and increasing production costs. Moreover, the high levels of accumulated waste in an intensive system may cause rapid deterioration of water quality, which may undermine the production. Lcarnitine is known as a growth-enhancer which shows promise as mitigator of crowding effects. The effects of stocking densities (4, 8, 11 and 14 kg m -2 ) on growth performance, feed utilization and body composition were evaluated during 75 days on turbot (75.6 ± 2.8 g) fed two dietary L-carnitine levels (40 or 240 mg kg -1 ). At the end of the feeding trial, total ammonia excretion (TAN) was measured postprandially for 24h. Specific growth rate and weight gain decreased with increasing stocking density. Fish held at 4 kg m -2 had higher final body weight (94-96 g) than fish held at higher densities (80-87 g). Protein efficiency ratio was higher in fish held at 4 kg m -2 (1.33-1.36), in comparison to fish stocked at 8 kg m -2 (0.98) or 14 kg m -2 (0.45). Voluntary feed intake decreased from 0.70 to 0.56% BW with increasing stocking density. Dietary L-carnitine supplementation did not affect growth performance and body composition, except for body L-carnitine content which increased from 75 to 128 mg kg -1 BW with supplementation. Fish fed 240 mg L-carnitine supplements had lower TAN that the ones fed 40 mg L-carnitine (p < 0.05). Key words: compensatory growth, feed additives, stress, husbandry, nitrogen excretion Desempenho de juvenis de pregado (Scophthalmus maximus) em função da densidade de estocagem e de níveis dietéticos de L-carnitinaRESUMO: A aquicultura de pregado (Scophthalmus maximus) utilizando elevadas densidades pode reduzir o crescimento e aumentar os custos de produção. Elevados níveis de metabolitos gerados nestes sistemas intensivos provocam rápida deterioração da qualidade da água, podendo também comprometer a performance da produção. A L-carnitina atua como potenciadora do crescimento parecendo ser promissora por atenuar alguns desses efeitos. Os efeitos de densidades (4, 8, 11 e 14 kg m -2 ) no desempenho do crescimento, composição corporal foram avaliados em pregados (75,6 ± 2,8 g) alimentados durante 75 dias a dois níveis dietéticos de L-carnitina (40 ou 240 mg kg -1 ). Após esse período, determinou-se a excreção de amônia pós-prandial durante 24 horas. Os peixes cultivados na menor densidade, 4 kg m -2 , apresentaram melhores taxas de crescimento e ganho de peso (94-96 g) em comparação aos mantidos em altas densidades (80-87 g). A taxa de eficiência proteica foi mais elevada a 4 kg m -2 (1,33-1,36), do que a densidades de 8 kg m -2 (0,98) ou 14 kg m -2 (0,45). A ingestão voluntária de alimento decresceu de 0,70 para 0,56% do peso corporal com o incremento da densidade. A suplementação de carnitina não afetou o crescimento e a composição corporal, com exceção do conteúdo de carnitine da carcaça que passou de 75 a 128 mg kg -1 . Peixes alimentados com suplementos de 240 mg L-carnitina apre...
