Effects of replacing fish meal by soybean meal along with supplementing phosphorus and magnesium in diet on growth performance of Persian sturgeon, Acipenser persicus

Abstract

Looking for replacing fish meal by cheaper and more sustainable protein sources is essential for reducing the cost of fish feeds. Soybean meal is a suitable alternative protein sources for carnivorous fish such as Persian sturgeon, Acipenser persicus. However, it contains antinutritional factors that may affect bioavailability of minerals and lead in reduced growth. Achieving a cost-effective diet that does not have negative effects on growth is the goal of aquaculture programs. A 10-week experiment was conducted with Persian sturgeon (352.07 ± 5.51 g) to determine the combined effects of phosphorous (SP), magnesium and phosphorous (SPMg), phytase (SF), phytase and magnesium (SFMg), phosphorous and phytase (SPF), phosphorous, magnesium and phytase (SPMgF) on weight gain, feed efficiency, specific growth rate, and condition factor. A control diet was prepared with fish meal as a control group. Inclusion of P, Mg, and phytase contents within soybean diets did not improve feed efficiency, and still, the control diet containing fish meal showed better weight gain and feed efficiency. Among soybean meal groups, feed efficiency and specific growth rate were significantly improved for fish fed the diet containing just phytase (SF) and both phytase and phosphorus (P ≤ 0.05). It was true for specific growth rate and condition factor. Phytase significantly enhanced growth whether included with or without phosphorous. This study showed that fish meal is more sufficient for Persian sturgeon, and soybean meal could be partly an alternative protein source if phosphorous supplied for fish by incorporation with microbial phytase or phosphorous.

Effects of insect diets on the gastrointestinal tract health and growth performance of Siberian sturgeon (Acipenser baerii Brandt, 1869)

“…To the authors’ knowledge, the present study is the first attempt to replace fishmeal with full-fat H. illucens and T. molitor meals for Siberian sturgeon nutrition. Currently, the main source of protein for farmed sturgeon is fishmeal with partial inclusion of plant meals, especially soybean meal [12, 35, 74, 83]. However, the present results suggest that insect meals can also substitute for FM in Siberian sturgeon diets without negative effects on growth performance.…”

Substituting fishmeal with extruded soybean meal in diets did not affect the growth performance, hepatic enzyme activities, but hypoxia tolerance of Dolly Varden (Salvelinus malma) juveniles

“…Several effective methods were conducted to overcome the antinutritional effect of SBM in aquaculture, including deceasing its content in diets (Bonvini et al, ), or supplementation with methionine and phosphate (Kokou et al, ), phosphorus and magnesium (Imanpoor & Bagheri, ), glutamine and arginine (Gu et al, ), lysine and methionine (Jiang et al, ), hydrolysed feather meal (Zhang et al, ), exogenous enzyme complex (Ramos et al, ), mannan oligosaccharides (MOS) (Torrecillas et al, ) or lactoferrin (Ulloa et al, ) in diets with SBM. Scientists were also looking for other plant protein sources, such as cottonseed meal (CSM) (Lee, Dabrowski, Blom, Bai, & Stromberg, ), chickpeas meal (CPM) (Christodoulou et al, ), extruded canola seed‐pea (ECSP) (Bandegan et al, ), rubber seed meal (RSM) (Deng, Mai, Chen, Mi, & Zhang, ) or fermented Jatropha kernel meal (FJKM) (Phulia et al, ) to partially or totally replace SBM in aquafeeds.…”

WITHDRAWN: 1H NMR-based metabolomics investigation of dietary soybean meal supplementation in hybrid sturgeon (Acipenser. baerii ♀× A. schrenckii ♂)”

“…However, the large inclusion of SBM in aquafeeds will cause negative effect on fish growth and health [ 9, 10] by the presence of anti-nutritional factors (ANFs) such as protease, phytates, lectins and saponins [ 11]. Current studies on the adverse influences of SBM replacement focused mainly on the growth restriction [ 12,13] and intestinal inflammation [14][15][16][17], with limited reports regarding the complete metabolomic alterations in fish.…”
