“…In this study, beluga sturgeon grew well throughout the experiment. This growth rate is comparable with or even higher than those reported by Jodun (2004) in Atlantic sturgeon, Vaccaro et al. (2004) in A. naccarii × A. baerii and Mohseni et al.…”

This study tried to determine the protein and energy requirements of growing beluga sturgeon Huso huso using a factorial approach. The experiment was composed of four small-scale growth trails covering different weight ranges. The fish fed at 0, 20, 40, 60, 80 and 100% of satiation. DWG had a steady increase throughout the experiment following a non-linear equation as Y = 1.433 (±0.056) × Ln(X) -2.740 (±0.261); r(2) = 0.99, p < 0.001, where Y = weight gain (g/day) and X = fish weight (g). The daily requirement of digestible energy (DE) for maintenance amounted to 79.09 kJ × BW (kg)(0.8) . The daily requirement of DP for maintenance calculated as 0.93 g × BW (kg)(0.7) . The relationship between DE intake (X) and DE gain (Y) expressed as Y = -0.0004 (±0.000) X(2) + 0.600 (±0.082) X -44.95 (± 6.72). Also, the relationship between DP intake (X) and protein gain (Y) was expressed as Y = -0.019 (±0.006) X(2) + 0.548 (±0.062) X - 0.498 (±0.121). The daily requirements of energy and protein were estimated as 79.09 kJ × BW (kg)(0.8) + 2.94 × DE gain and 0.93 g × BW (kg)(0.7) + 2.63 × DP gain. Apparently, beluga sturgeon is inefficient in converting energy and protein into body tissue. Therefore, energy content of the diet should be sufficiently high to satisfy large energy demands in beluga sturgeon and also to reduce the catabolism of protein.

“…Feeding frequency should target optimal feed intake and the growth (Mohseni et al, 2006). Several studies have reported the effects of feeding rate on the growth performance of white sturgeon (Deng et al, 2003;Hung et al, 1995), Atlantic sturgeon (Acipenser oxyrinchus) (Jodun, 2004;Kelly and Arnold, 1999), shortnose sturgeon (Acipenser brevirostrum) (Giberson and Litvak, 2003), Persian sturgeon (Acipenser persicus) (Yousefpour et al, 1998), and great sturgeon (Mohseni et al, 2006;Pourali et al, Aquaculture 448 (2015) …”

Summary The objective of this study was to evaluate the feeding rate of the great sturgeon (Huso huso) young of the year (YOY) and to investigate the effects of different feeding rates in maintaining the weight of fish during short periods of winter starvation. Six feeding rates of 0.2, 0.4, 0.6, 0.8, 1.0% body weight (BW) day−1 and feeding to satiation were considered for the first experiment. Each feeding rate was randomly assigned to three replicate tanks, with continuous feeding throughout a 5‐week winter period of water temperatures below 10°C. Fifteen fish were held in each of 18 tanks with an average initial body weight of 219.6 ± 6.9 g. After 5 weeks of feeding, the best performance was observed in fish fed 1% BW day−1, but negative growth was observed in fish fed 0.2% BW day−1. In the second experiment, fish were deprived of feed for 3 weeks at winter temperatures. Weights and condition factors of all fish decreased during starvation, while the differences in mean weight before and after the starvation period were not significant in fish fed a level of 0.2% BW day−1 and those fish fed to satiation. No mortality was recorded in either experiment. Results of this study indicate that a feeding rate of 1% BW day−1 would be sufficient for commercial fish farming of YOY of this species to maintain them over winter. Also, to maintain fish weights and prevent weight loss in overwintering ponds, a feeding rate of around 0.3% BW day−1 seems appropriate for hatcheries.
