Sodium alginate supplementation modulates gut microbiota, health parameters, growth performance and growth‐related gene expression in Malaysian MahseerTor tambroides

“…Muscle growth by hyperplasia and hypertrophy in fish is controlled by several genetic factors such as growth hormone ( GH ), insulin‐like growth factors ( IGF s), myogenic regulatory factors ( MRF s) and myostatin (Johnston et al, ). Previous studies on different aquatic species already reported that dietary supplementation of sodium alginate significantly improves the growth rate of farmed fish (Chung et al, ; Mona et al, ; Van Doan et al, ; Vollastad et al, ; Xia et al, ; Yeh et al, ). However, actual role of sodium alginate in regulating muscle growth at cellular and molecular levels in fish still needs to be clarified.…”

“…Sodium alginate, which is one of the brown algal non‐digestible polysaccharides, is commonly used as probiotic encapsulation (Cordero et al, ; Rosas‐Ledesma, León Rubio, Alarcón, Moriñigo, & Balebona, ; Tapia‐Paniagua et al, ) and may function as prebiotics. A significant number of previous studies reported that dietary supplementation of sodium alginate improved the growth performance and feed utilization of various fish and shellfish species (Chung, Liu, Chen, & Cheng, ; Mona, Rizk, Salama, & Younis, ; Van Doan, Hoseinifar, Tapingkae, Tongsiri, & Khamtavee, ; Vollastad, Bogwald, Gåserød, & Dalmo, ; Xia et al, ; Yeh, Chang, Chang, Liu, & Cheng, ). Besides improving growth performance and feed utilization, sodium alginate has also been known to stimulate the innate immune system of various fish and shellfish species (Cheng, Chen, & Chen, ; Cheng, Liu, Kuo, & Chen, ; Cheng & Yu, ; Chiu, Tsai, Hsu, Liu, & Cheng, ; Harikrishnan et al, ; Mona et al, ; Van Doan et al, ; Vollastad et al, ; Yeh et al, ).…”

“…Intensification of aquaculture operations, which is now a global trend for commercial aquaculture (Msangi et al, ), is usually accompanied with stress leading to fish growth reduction, immunosuppression and susceptibility to infectious diseases, causing major economic loss for farmers (Abdelsalam, Elgendy, Shaalan, Moustafa, & Fujino, ; Food & Agriculture Organisation, ; Mona, El‐Sayed, Salama, & Youris, ; Syahidah, Saad, Hassan, & Abdehad, ). Until recently, these problems have been largely addressed with the use of antibiotics; however, the negative effects such as the development of strains of bacteria resistant to antibiotics, bioaccumulation of drug residue and impact of released antibiotics on the environment, have led to forbidding its use in the culture of edible animals (Upadhaya & Kim, ).…”

Dietary supplementation with low molecular weight sodium alginate improves growth, haematology, immune reactions and resistance againstAeromonas hydrophilainClarias gariepinus

“…Compared with the control catfish diet, the catfish diet containing 3% LMWSA enhanced the FBW and WG after 8 weeks. Similar results were obtained in Nile tilapia ( Oreochromis niloticus ) (Van Doan, Hoseinifar, Tapingkae, & Khamtavee, "?>), sea cucumber ( Apostichopus japonicus ) (Xia et al, ) and Procambarus clarkii (Mona, Rizk, Salama, & Younis, ); reportedly, compared with normal basal diets, dietary supplementation with LMWSA either alone or combined with Lactobacillus plantarum enhanced the growth performance of Nile tilapia. However, there were no significant differences in SGR and FCR in Nile tilapia fed diets containing 2% and 3% LMWSA (Van Doan et al, ).…”
