“…Effects of seaweed supplementation on blood cell counts are variable; studies in human or other mammals showed limited effects [ 6 , 8 ], but increased counts were observed when chicken and fish were fed Laminaria japonica or Sargassum oligocystum , respectively [ 9 , 10 ]. Such addition to animal feed is not only associated with increased growth and feed conversion ratios in chicken and fish, but also enhanced status of innate and adaptive immune defenses and immune responsiveness and survival after infectious challenge [ 11 , 12 , 13 ].…”

Multiple health benefits have been ascribed to brown seaweeds that are used traditionally as dietary component mostly in Asia. This systematic review summarizes information on the impact of brown seaweeds or components on inflammation, and inflammation-related pathologies, such as allergies, diabetes mellitus and obesity. We focus on oral supplementation thus intending the use of brown seaweeds as food additives. Despite the great diversity of experimental systems in which distinct species and compounds were tested for their effects on inflammation and immunity, a remarkably homogeneous picture arises. The predominant effects of consumption of brown seaweeds or compounds can be classified into three categories: (1) inhibition of reactive oxygen species, known to be important drivers of inflammation; (2) regulation, i.e., in most cases inhibition of proinflammatory NF-κB signaling; (3) modulation of adaptive immune responses, in particular by interfering with T-helper cell polarization. Over the last decades, several inflammation-related diseases have increased substantially. These include allergies and autoimmune diseases as well as morbidities associated with lifestyle and aging. In this light, further development of brown seaweeds and seaweed compounds as functional foods and nutriceuticals might contribute to combat these challenges.

“…There are no other studies addressing this topic in fish, but dietary supplementation with aquatic plants, which are abundant in phytol, improved fish growth performance. For example, dietary fortification with common duckweed, Lemna minor meal [26], Sargassum oligocystum hot-water extract [27], and Entromorpha intestinalis extract [28] significantly improved the growth performance of rohu, Labeo rohita, Iridescent shark, Pangasius hypophthalmus, and electric yellow cichlid, Labidochromis caeruleus, respectively.…”

Nile tilapia, Oreochromis niloticus, (2.00 ± 0.02 g) were reared in 16 70-L tanks (40 individual/tank) and fed diets (approx. 345 g/kg protein, approx. 87 g/kg crude fat) containing 0 (CTL), 75 (PH-75), 150 (PH-150), and 300 (PH-300) mg/kg phytol (n = 4). After 60 days of feeding (4% daily), growth performance, humoral immune parameters, and gut bacteria were analyzed. Also, hepatic antioxidant parameters were determined before and after the fish were transported in plastic bags for 6 hr. The results showed that PH-75 exhibited the highest final weight (P<0.001), weight gain (P<0.001), feed intake (P<0.001), feed efficiency (P=0.015), plasma lysozyme activity (P=0.004), and intestinal Lactobacillus sp. population (P=0.017), among the treatments. The highest plasma alternative complement activity (P=0.006) and the lowest intestinal total viable bacteria (P=0.027) were observed in PH-75 and PH-150. The highest plasma alkaline phosphatase activities were observed in PH-75 and PH-300 (P=0.014). The highest blood leukocyte (P=0.008), monocyte (P=0.010), and eosinophil (P<0.001) were observed in PH-300, while the highest blood neutrophil was observed in all phytol treatments (P<0.001). The highest hepatic lipid peroxidation was observed in PH-300, whereas PH-75 and PH-150 showed the lowest values (P<0.001). The highest hepatic reduced glutathione was observed in PH-75, also PH-150 exhibited significant elevation in this parameter, compared to CTL (P<0.001). Transportation led to significant elevations in the hepatic antioxidant enzymes’ activities in CTL, PH-75, and PH-150; the highest activities were related to PH-75 and PH-150 treatments, which had also the highest post-transportation survivals (P<0.001). In conclusion, phytol is a suitable feed supplement for Nile tilapia, improving growth performance and welfare, particularly at 75 mg/kg.
