“…The increased immune response can have a positive impact on increasing body resistance and reducing shrimp mortality. This is confirmed by Jasmanindar et al [ 39 ], who found that the low SR in the treatment without the extract had a relationship with a weak immune system compared to the treatment with seaweed extract. The combination of phytobiotics (thyme essential oil, red thyme, and rosemary pepper) applied in a supplement for 20 days has significant benefits for improving antioxidant protection, reducing the impact of stressors, and modulating the immunity of tilapia against A. hydrophila infection [ 17 ] .…”

Objective: This study aimed to evaluate the combination of hairy eggplant (Solanum ferox) and bitter ginger (Zingiber zerumbet) on the production performance and hematological parameters of whiteleg shrimp (Litopenaeus vannamei). Materials and Methods: Four treatments were formulated in the test feed, where P1 (control + commercial vitamin C); P2 (120 ml/l combination of S. ferox and Z. zerumbet ); P3 (100 ml/l); and P4 (80 ml/l) 6,000 post-larvae shrimp with an average initial weight of 0.2 gm were randomly stocked in four groups, with three replications per treatment, and 500 were stocked in each pond with a total of 12 pounds. Results: Based on the results, there were significant differences in production performance (survival, absolute weight growth, specific growth rate, and feed conversion ratio). Biologically, the best performance was found in the P3 treatment (100 ml/l). In this treatment, the total number of hemocytes and the number of hyaline hemocytes were much higher, and this was not the case in the control treatment (P1), where the number of semi-granular and granular cells was significantly higher than the treatment group (p < 0.05) . Conclusions: This study confirmed that supplementation of 100 ml/l of S. ferox and Z. zerumbet could improve the production performance and hemato-immunological parameters of whiteleg shrimp, with functional potential to be developed in phytobiotic-based commercial diets for shrimp.

Improper cultivation of white shrimp (Litopenaeus vannamei) can cause Vibriosis attacks caused by Vibrio parahaemolyticus. Prevention efforts include increasing the body’s defense system in shrimp by administering immunostimulants. This study aims to determine the effect of adding Caulerpa racemosa extract on reducing total bacteria and total Vibrio in the hepatopancreas and hemolymph of white shrimp after being infected with V. parahaemolyticus. This research used a Completely Randomized Design (CRD). Data analysis used Analysis of Variance (ANOVA) and calculations continued with the Duncan Test (DMRT). The results of the study showed that administration of C. racemosa extract had an effect on reducing total bacteria and total Vibrio in the hepatopancreas with the best results reducing total bacteria at P3 16.60×106 CFU/mL and reducing total Vibrio at P3 12.20×106 CFU/mL. Apart from that, administration of C. racemosa extract also had an effect on hemolymph with the best results of reducing total bacteria at P3 12.37 × 106 CFU/mL and reducing total Vibrio at P3 10.03 × 106 CFU/mL. The conclusion of this research is that the addition of C. racemosa extract has an effect on reducing total bacteria and reducing total Vibrio in the hepatopancreas and hemolymph of white shrimp.

The purpose of this study was to determine the effect of administration Caulerpa racemosa extract on total bacteria and survival rate of white shrimp (Litopenaeus vannamei) after infected by Vibrio parahaemolyticus. This study used a Completely Randomized Design with five treatments and three replications. Shrimp were divided into four groups, one control group without C. racemosa extract, another three groups were administrated with C. racemosa extract in different doses; 3 μg/g (P1), 6 μg/g (P2) and 9 μg/g (P3) by injection. After 24 hours, the control group was divided into two groups, negative control (K-) was injected by PBS and positive control (K+) also another three groups (P1, P2 and P3) were infected by V. parahaemolyticus. Observed parameters were total bacteria and survival rates. On the 1st day, the total bacteria was lower in the treatment with C. racemosa extract than K+ and significantly different (P <0.05). On the 7th day, total bacteria increased again, but in P3 (20.46 ×104 CFU/ml) was lower than K+ and significantly different (P <0.05). The highest survival rates was 93.33% (P2) and the lowest was 56.67% (K+). It can be concluded that C. racemosa extract can be given to L.vannamei at dose 6 μg/g.
