Partial Replacement of Fish Meal by Fermented Soybean Meal in Diets for Black Sea Bream, Acanthopagrus schlegelii, Juveniles

Abstract

The effect of fish meal (FM) substitution with fermented soybean meal (FSBM) in the diets of the carnivorous marine fish, black sea bream, Acanthopagrus schlegelii, was investigated. An 8-wk feeding trial was conducted with black sea bream (11.82 ± 0.32 g; mean initial weight) in indoor flowthrough fiberglass tanks (25 fish per tank). Six isonitrogenous and isoenergetic diets were formulated, in which FM was replaced by FSBM at 0% (control diet), 10% (FSBM10), 20% (FSBM20), 30% (FSBM30), 40% (FSBM40), or 50% (FSBM50), respectively. Each diet was fed to triplicate groups of fish twice daily to apparent satiation. The results showed that there was no difference in survival of black sea bream during the feeding trial. Fish fed the FSBM10 or FSBM20 diet showed comparable growth performance compared with fish fed the control diet (P > 0.05), whereas more than 30% replacement of FM adversely affected weight gain and specific growth rate (P < 0.05). Feed intake was significantly lower for fish fed the FSBM50 diet compared with fish fed the control diet. Feed conversion ratio (FCR) tended to increase with increasing dietary FSBM with the poorest FCR observed for fish fed the FSBM50 diet. Protein efficiency ratio and protein productive values showed similar patterns. Apparent digestibility of nutrients significantly decreased with increasing dietary FSBM level. With the exception of protein content, no significant differences in whole body and dorsal muscle composition were observed in fish fed the various diets. Fish fed the FSBM50 diet had significantly lower intraperitoneal ratio than fish fed the control or FSBM10 diet. Hepatosomatic index and condition factor were unaffected by dietary treatments. This study showed that up to 20% of dietary FM protein could be replaced by FSBM protein in the diets of juvenile black sea bream.

“…More studies to elucidate the reason why abalone fed the diet containing fermented soybean meal showed poorer growth performance than that fed diet containing soybean meal is needed. Unlike this study, however, d ietary inclusion of the fermented plant protein sources, such as soybean meal and cottonseed meal produced promising effect on performance of fish (Lim & Lee, 2011;Zhou et al, 2011).…”

“…Dietary inclusion of fermented plant protein sources, such as soybean and cottonseed meals also produced a promising effect on performance of Nile t ilap ia, Oreochromis niloticus Linne and black sea bream, Acanthopagrus schlegeli Bleeker (Lim & Lee, 2011;Zhou et al, 2011). A study by Kim et al (2015) on abalone, H. discus Reeve revealed that 1000 g/kg substitution of L. japonica with rice bran, [an agricu lture byproduct and rich in the nutrients such as crude protein and vitamins (Gao, Kaneko, Hirata, Toorisaka, & Hano, 2008)], at 200 g/kg in the diet was successful in terms of abalone weight gain.…”

Nutritive Value of Diets Containing Digeston-1 as a Feed Additive for Nile Tilapia (Oreochromis niloticus) Fingerlings

“…Therefore, the improved growth may be attributed mostly to the improvement in the nutritional value and the elimination of antinutritional factors in fermented soybeans [3]. Fan et al [26] found that markedly lower concentrations of antinutritional components such as phytic acid, lectin, and urease were found in FSBM as compared with nonfermented SBM. Similarly, Wu and Jing [7] suggested that fermentation could improve protein digestibility, essential amino acid index (EAAI) and protein efficiency ratio (PER) of soybean meal (SBM).…”

Effect of dietary soybean meal and multienzyme on intestine histology of beluga sturgeon (Huso huso)

“…Several studies have reported that even when heat-treated, standard (solvent-extracted) and full-fat SBM-containing feeds supplemented with limiting amino acids, can lead to decreased growth and energy digestibility in farmed species (Merrifield and Olsen 2011;Krogdahl et al 2003). However, considerable success in partially or totally replacing FM with SBM in diets for fish species has been achieved (El-Saidy and Gaber 2002; Yaghoubi et al 2016;Zhou et al 2011).…”
