“…In general, freshwater fish species contain relatively high levels of ARA in comparison with marine species, because they are able to convert essential linoleic acid to ARA. It has been suggested that the response of fish to dietary ARA depends on the basal ARA levels in their body, as well as on the dose and duration of feeding (Dagar et al. 2010).…”

Dietary enrichments with the arachidonic acid (ARA)-rich microalga, Parietochloris incisa, on the survival of guppy (Poecilia reticulata) fry were examined. Diets were applied via Artemia enrichment to fish from two commercial farms for 34 and 36 days of experimental period (trials 1 and 2, respectively). In trial 1, Artemia nauplii were enriched with dry biomass of whole algal cells at 0 (control), 0.1, 0.2 and 0.4 mg mL )1 . Fry fed with Artemia enriched with 0.4 mg mL )1 demonstrated the lowest mortality rates (24% and 1% in farms 1 and 2, respectively) compared with controls (36% and 13% in farms 1 and 2, respectively). In trial 2, fry were fed with Artemia, enriched with whole algal cells (0.4 mg ml )1 ), algal hexane extract (HE; containing primarily ARA-rich triacylglycerols and b-carotene; 0.19 mg ml )1 ) or the extraction residue (0.28 mg ml )1 ). Acute stress (5 min air exposure) was applied after 18 days. The lowest mortality was recorded in the whole alga-fed group (av. 26% and 2.6% in farms 1 and 2, respectively), with a slightly, but not significantly higher mortality in the HE-fed group (av. 29% and 6.2% in farms 1 and 2, respectively). Elevated lysozyme was associated with the reduced mortality. Overall, the use of P. incisa as a dietary supplement for guppy fry during their first month of life enhanced their survival and stress resistance.

“…Microalgae have also been recommended as a good feed supplement for counteracting intestinal inflammation produced by soybean meal in Atlantic salmon ( Salmo salar ) (Grammes et al, ). Short‐term beneficial effects of diets containing microalgae or microalgae fractions have also been described in fish (Bagni et al, ; Dagar, Zilberg, Cohen, Boussiba, Khozin‐Goldberg, ) and could be advantageous to render fish more fit when a stress of some sort is expected, avoiding the need to use these high‐priced diets on a daily basis.…”

Nannochloropsis gaditana was tested as functional ingredient in low fishmeal diets for gilthead seabream juveniles, and its short‐term effects were evaluated in terms of intestinal morphology, digestive function, intestinal immunological and oxidative status, and intestinal microbiota. A diet with 850 g/kg of the protein provided by plant feedstuffs and 150 g/kg provided by fishmeal was used as control, and three other diets identical to the control were supplemented with 5, 7.5 and 15 g/kg N. gaditana meal and fed to 56.6 g fish for 37 days. At the end of this period, intestinal mucosa integrity and digestive capacity (luminal enzyme activity and absorption) were not altered by dietary microalgae supplementation. Intestinal transcript levels of key markers of inflammation (IL‐1β and TNF‐α) and of key enzymes involved in redox homeostasis (CuZnSOD, MnSOD and catalase) were also similar across experimental groups. However, microbiota richness increased with dietary supplementation of microalgae, and such modulation requires further investigation, particularly regarding its potential effects on disease resistance at short and long term.
