“…The immune variables evaluated (THC, PO, Agglutinating titre and serum protein concentration) were not significantly affected by fish oil replacement and were similar to other studies (Maggioni et al, , Costa et al, and Schleder et al, ). This can be considered positive because even total replacement of fish oil by Aurantiochytrium sp .…”

This study evaluated the use of microalgae (Aurantiochytrium sp.) meal as a substitute for fish oil in the diet of juvenile Pacific white shrimp (Litopenaeus vannamei) reared in a clear‐water system. Dietary treatments at five replacement levels (0%, 25%, 50%, 75%, 100%) were performed in triplicate. After 46 days, only a slight difference in shrimp final weight was observed among treatments (0.61 g). An increase in final weight was observed with replacement of up to 50% fish oil for microalgae meal, while the optimal percentage of replacement estimated was 44.7%. Feed conversion rate (FCR) of animals fed a diet of Aurantiochytrium sp.meal to replace up to 50% fish oil decreased, and the optimal percentage of replacement estimated was 49.3%. The fatty acids profile in shrimp muscle tissue demonstrated an increase in docosahexaenoic acid (DHA) from 10.03% to 14.28% with increased replacement of fish oil by microalgae meal in the diet. Therefore, the partial replacement of fish oil by microalgae meal resulted in improved shrimp growth and FCR, and total replacement of dietary fish oil had no negative effects on these parameters. In addition, inclusion of microalgae meal raises the level of DHA in shrimp muscle.

“…In recent years, the use of diets containing bioactive compound ingredients has gained prominence in L. vannamei aquaculture practices (Niu et al, ; Yang et al, ), with beneficial effects such as improvement in the immune system (Macias‐Sancho et al, ), resistance to temperature stress (Schleder et al, ), increased digestive capacity and greater resistance to white spot syndrome virus infection (Shelder et al, 2018), resistance to hypoxia stress condition (Pakravan, Akbarzadeh, Sajjadi, Hajimoradloo, & Noori, ), improvement in the intestinal antimicrobial activity (Pourmozaffar, Hajimoradloo, Paknejad, & Rameshi, ) and increased antioxidant capacity (Yang, Wu, Jian, & Zhang, ).…”

This study investigated the effects of the inclusion of Mauritia flexuosa fruit pulp in the diet on the growth performance, economic benefit, muscle composition, total contents of carotenoids and flavonoids, chromaticity parameters, total antioxidant capacity, and lipid peroxidation in the hepatopancreas and muscle of the juvenile shrimp Litopenaeus vannamei (weighing 1.26 ± 0.023 g). Five diets (37% protein, 10% lipid) consisting of 0 (control), 1.25%, 2.50%, 5.00% and 10.00% (w/w) M. flexuosa fruit pulp were formulated and provided to the shrimps (n = 50 per tank, treatments in triplicate) for 31 days. Results showed that there were no significant differences between the treatments in terms of the growth capacity, chromaticity parameters, muscle composition and total flavonoid content of shrimps (p > .05). However, the carotenoid content in the muscle and hepatopancreas of the shrimps was significantly increased due to the dietary carotenoids present in M. flexuosa fruit pulp (p < .05). This increase in the carotenoid content directly favoured the increase in the antioxidant capacity in the hepatopancreas and muscle of the shrimps (R2 = 0.99 and R2 = 0.97 respectively; p < .05). There was also a direct relationship between the carotenoid content and the decrease in lipid peroxidation in the hepatopancreas (R2 = 0.90; p < .05). The feed cost kg−1 in terms of weight gain and protein production decreased with the inclusion of high levels of M. flexuosa fruit pulp, reaching 8.11% and 18.76% of cost reduction, respectively, with the addition of 5.00% of M. flexuosa fruit pulp. Therefore, the inclusion of M. flexuosa fruit pulp in the diets of shrimp can increase the carotenoid content and the antioxidant capacity in the hepatopancreas and muscle, reduce lipid peroxidation in the hepatopancreas, and probably provide economic benefits for the rearing of juvenile shrimps.

“…Alginate contains high nutritional value, various bioactive compounds, and minerals (Cabrita et al, 2016). As prebiotic, alginate is an indigestible food ingredient which beneficial for parasite organism activity, leading to increasing growth and nonspecific immune responses (Poongodi et al, 2012;El-Desouky et al, 2012;Peso-Echarri et al, 2012;Schleder et al, 2017), increasing lipid metabolism (Güroy et al, 2011), viruses resistance and resistance (Boonsri et al, 2017), increasing intestinal effectiveness (Michiels et al, 2012), and increasing the resistance of organisms to stress (Nath et a.l, 2012). In addition, alginate also potentially increases the abundance of bacteriides capillosus bacteria in the gut (Kuda et al, 2017) and has antiviral, antifungal and antibacterial activity (Niu et al, 2015).…”

This study aimed to investigate the effectiveness of synbiotic (prebiotic alginate and probiotic bacteria Micrococcus spp) on the immune responses, growth performance, and bacterial resistance of freshwater crayfish. The experimental diets were formulated in three levels of synbiotic: the probiotic bacteria Micrococcus spp+100 mg/L alginate (Syn100), Micrococcus spp+200 mg/L alginate (Syn200), Micrococcus spp+300 mg/L alginate (Syn300), each level was mixed with tested feed. The basal diet (without synbiotics) served as the control diet. During 40 days of rearing, immune responses observations were conducted every 10 days, while the crayfish weight were recorded on day 40. Furthermore, the challenge test was performed against the pathogenic bacteria of A. hydrophila and reared for a week. The result showed that synbiotics treatment of Syn300 and Syn200 could improve the immune response and increased the growth rate (P<0.05). Both were also heavier than the Syn100 treatment. The highest resistance to A. hydrophila pathogenic bacteria by demonstrating a higher survival rate was Syn300 and followed by Syn200 (70.00 ± 0% and 73.33 ± 5.77%, respectively), compared to Syn100 (56.67 ± 3.33%) and the control (33.33 ± 3.33%). The synbiotic Micrococcus spp. combined with alginate potentially induced immune responses, increased growth performance, and improved bacterial pathogens resistance, making it an ideal synbiotic to be developed. Keywords: synbiotic, prebiotic, probiotic, Sargassum sp., alginate, brown algae ABSTRAK Penelitian ini bertujuan untuk menguji efektivitas penggunaan sinbiotik (prebiotik alginat dan probiotik Micrococcus spp) terhadap respons imun, performa pertumbuhan dan resistensi lobster air tawar. Tiga perlakuan sinbiotik yaitu Micrococcus spp+100 mg/L alginat (Syn100), Micrococcus spp+200 mg/L alginat (Syn200), Micrococcus spp+300 mg/L alginat (Syn300), masing-masing dicampurkan ke dalam pakan dan diberikan ke lobster. Pakan tanpa campuran prebiotik digunakan sebagai pakan kontrol. Selama 40 hari pemeliharaan, pengamatan respon imun dilakukan setiap 10 hari dan pada hari ke-40 pemeliharaan dilakukan pengukuran bobot lobster. Selanjutnya, lobster di uji tantang dengan bakteri A. hydrophila dan dipelihara kembali selama satu minggu. Hasil penelitian menunjukkan bahwa pemberian pakan yang mengandung sinbiotik Syn300 dan Syn200 dapat meningkatkan respon imun dan pertumbuhan (P<0.05) lebih tinggi dibandingkan dengan perlakuan Syn100, sementara bobot tubuh terendah didapat pada perlakuan kontrol. Resistensi lobster tertinggi terhadap bakteri A. hydrophila yang ditunjukkan dengan sintasan tertinggi didapatkan pada perlakuan Syn300 (70.00±0.00%) dan Syn200 (73.33±5.77%) dibandingkan dengan perlakuan Syn100 (56.67±3.33%) dan kontrol (33.33±3.33%). Penelitian ini membuktikan bahwa sinbiotik Micrococcus spp. yang dikombinasikan dengan alginat dapat menginduksi respons imun, meningkatkan performa pertumbuhan ,dan resistensi terhadap patogen sehingga merupakan sinbiotik yang ideal untuk dikembangkan.
