The replacement of fish meal with fermented soya bean meal or soya bean meal in the diet of Pacific white shrimp ( Litopenaeus vannamei )

Abstract

The present study evaluated the effects of replacing fish meal (FM) with soya bean meal (SM) or fermented soya bean meal (FSM) on growth, nutrient utilization, digestive enzyme activity and intestinal histology of Pacific white shrimp. The basal diet (control) contained 18% FM, and then, FM in basal diet was replaced by 1/6 (17%), 1/3 (33%) and 1/2 (50%) by the inclusion of SM and FSM, referring to SM17, SM33, SM50, FSM17, FSM33 and FSM50 respectively. The shrimp (3.0 g) were fed one of the seven diets for 8 weeks. The results showed that the control group had the highest weight gain (WG) (653.8%) and the lowest feed conversion ratio (FCR) (1.61). SM33, SM50 and FSM50 groups showed significantly lower WG, crude protein (CP) digestibility, hepatopancreatic protease, amylase activity and higher FCR than the control (p < .05). The villi height of SM33, SM50 and FSM50 groups and the intestinal wall thickness of SM groups and FSM50 group were significantly lower than those of the control (p < .05). In conclusion, fish meal (18%) in white shrimp diet could be replaced by 1/6 (17%) and 1/3 (33%) with SM and FSM respectively. Fermented soya bean meal could replace more fish meal than soya bean meal did.

Effects of Dietary Nucleotide Supplementation on Performance, Profitability, and Disease Resistance of Litopenaeus vannamei Cultured in Indonesia under Intensive Outdoor Pond Conditions

“…Anti-nutritional factors in SBM might constitute an important factor responsible for the abnormal intestinal condition and reduced nutrient absorption [ 53 ]. A prior study by Yao et al [ 54 ] indicated that the use of high SBM levels in feeds could induce intestinal damage and significantly decrease cell membrane thickness in the hepatopancreas of PWS. In the study herein, the inclusion of 0.1% nucleotides was capable of partially preventing the development of marked histological hepatopancreas alterations observed in the shrimp fed with 8% and 6% FM.…”

Effects of fishmeal replacement with cottonseed protein concentrate on growth, digestive proteinase, intestinal morphology and microflora in pearl gentian grouper (♀ Epinephelus fuscoguttatus × ♂ Epinephelus lanceolatu )

“…The feed conversion rate (FCR) of R36 and R60 groups was significantly higher than that of the R24 group. According to the research of Yao et al (2020), plant protein substitution causes amino acid imbalance, which can evidently inhibit the growth performance of fish with plant protein increasing replacement. A study on digestive proteinase activity indicated that the digestive tract structure of fish varied with different diets (Pan et al, 1996).…”

“…For sustainable development of aquaculture, one of the solutions is to replace part or all of the FM in aquatic diet with plant protein (Hardy et al, 2010; Kaushik et al, 2004). Experiments have been carried out to replace FM with plant protein (Olsen et al, 2007; Torstensen et al, 2008; Yao et al, 2020).…”

Effect of feed enzymes and functional immunostimulants supplementation on growth performance and overall health of postlarvae and juvenile Pacific white shrimp, Penaeus vannamei, fed soybean‐based diets

“…Marine shrimp aquaculture agro‐industry is among the top consumers of the global FM supply. The reported minimum amount of FM in shrimp feeds necessary for normal growth varied in different studies, ranging from 24% to 26% diet by weight (Q. Yang et al, 2015; Yun et al, 2017), to about 13%–15% diet (Alvarez et al, 2007; Yao et al, 2020) or even completely FM free (Galkanda‐Arachchige et al, 2021; Guo et al, 2020; P. Yang et al, 2021).…”
