“…Overall, shrimp fed 3% and 6% periphyton supplement showed better immune response with higher resistance to Vibrio infection compared with control. This is comparable to the findings of Nonwachai et al (2010) who reported better resistance in L. vannamei upon challenge with V. harveyi when fed algal meal-incorporated diet compared with control. This further confirms the potential role of periphyton in eliciting non-specific immune responses of shrimps.…”

“…In the present study, dietary periphyton supplementation at 6% level significantly enhanced ( P < 0.01) the final body weight of tiger shrimp compared with control. Similarly, better growth performance was recorded in shrimps fed microalgae‐supplemented diet (Ju, Forster & Dominy ; Nonwachai, Purivirojkul, Limsuwan, Chuchird, Velasco & Dhar ). Since, there was no variation in macronutrients level in the experimental diets, better growth recorded in shrimp fed periphyton‐supplemented diets might be attributed to unknown growth promoters or higher digestive enzymes secretion in gut and hepatopancreas (Anand et al .…”

A 60‐day indoor trial was conducted to study the effect of periphyton supplementation on metabolic and immune responses in tiger shrimp, Penaeus monodon. Periphyton developed over bamboo substrate in outdoor tanks (15 m2) was used as dietary supplement for P. monodon (2.02 ± 0.04 g) reared in 1000 L FRP tanks. Graded levels of periphyton were included in shrimp basal diets: 0% (P0), 3% (P3), 6% (P6), 9% (P9) and P0 diet with natural periphyton (NP) over bamboo substrate. At the end of the trial, P6 and NP showed significantly higher (P < 0.01) growth rate, 23.9% and 20%, respectively, compared with control, P0. Comparatively, lower level of metabolic enzymes, such as lactate dehydrogenase, malate dehydrogenase, aspartate aminotransferase and alanine aminotransferase, was recorded in treatments P3, P6 and NP compared with control, P0. The periphyton‐supplemented group, P3 had significantly higher (P < 0.05) superoxide dismutase (15.83 ± 0.96) and catalase activity (15.73 ± 0.69) compared to 6.88 ± 2.84 and 9.15 ± 0.67 unit mg−1 protein min−1, respectively, in P0. Similarly, higher total haemocyte counts, 32.58 ± 1.30, 28.51 ± 3.12 and 27.26 ± 4.43 × 106 cells mL−1, were recorded in P6, NP and P3, respectively, compared to P0, 23.57 ± 1.80 × 106 cells mL−1. After challenge with Vibrio harveyi, P3 recorded the highest relative percentage survival 67% followed by NP (58%) and P6 (42%) compared with control. However, treatment with highest periphyton inclusion (P9) did not differ significantly with P0 on growth and immunological parameters. This study indicates that periphyton supplementation at 3–6% level improves growth, immune response and metabolic activities in P. monodon.

“…The increase in the percentage of T. chuii into the feed led to the increase in the antioxidant properties of the feed. The addition of microalgae has been shown to increase the antioxidant compounds such as astaxanthin and lutein in the aquaculture feed (Li et al 2015;Nonwachai et al 2010). Due to the carcinogenic and tumorigenic nature of BHT, the potential of T. chuii as a natural source of antioxidants is very promising and can be considered as a substitute to replace the harmful synthetic substances.…”

Tetraselmis chuii biomass as a potential feed additive to improve survival and oxidative stress status of Pacific white-leg shrimp Litopenaeus vannamei postlarvae

Shrimp is an important traded fishery commodity. When subjected to stress, shrimp usually suffers from oxidative stress, which leads to cell injury, senescence, and death. To maintain shrimp good health, performance and production, antioxidant and immune systems are important. Natural antioxidants found in microalgae may be used to increase the cell protection against oxidative damage, being a promising alternative to the carcinogenic synthetic antioxidants. In this study, Tetraselmis chuii was evaluated for its effect on survival, growth and oxidative stress biomarkers on Litopenaeus vannamei postlarvae (PL). The antioxidant properties of the formulated feed with T. chuii inclusion were determined using four antioxidant chemical assays. Meanwhile, the oxidative stress biomarkers on PL were analyzed by hydrogen peroxide, membrane stability and lipid peroxidation assays. Results showed that PL reared on diets supplemented with 50% T. chuii had a significantly higher (P B 0.05) survival (97.6 ± 1.4%) and lower oxidative stress in terms of hydrogen peroxide content (10.08 ± 0.4 mM g -1 FW) and electrolyte leakage (10.8 ± 0.3%). The result of this study also showed that shrimp PL reared on diets supplemented with microalgal, T. chuii have high resistance to reverse salinity stress test (76.7-100%). However, no significant differences (P C 0.05) were found in the growth and lipid peroxidation. Due to the positive effect on oxidative stress status, survival and resistance to salinity stress, the feeding of L. vannamei PL with diet containing at least 50% of T. chuii is recommended as a natural source of antioxidant for PL.

“…Eicosanoids are synthesized more actively in histophagous oligohymenophorean protozoans than in free-living ciliates (Szablewski & Hadás 1991) and serve, along with other substances, to evade or disable immune defense mechanisms of invertebrate hosts (Stanley 2000). Such nonspecific immune responses have repeatedly been reported in shrimp raised on diets supplemented with marine algae meals rich in DHA and ARA, which show significant im provement in immune parameters, such as total hemocyte count, phenoloxidase activity, SOD activity, and bactericidal activity (Nonwachai et al 2010). We propose the hypothesis that females are most frequently infected because juveniles and males contain relatively low levels of lipids; hence, infection does not successfully de velop.…”
