Nutritional Applications of Species of Spirulina and Chlorella in Farmed Fish: A Review

Abstract

Microalgae contain 50% crude protein value, which is comparable with the amino acid profile of fish meal, and high levels of polyunsaturated fatty acids make their use in animal feeding and nutrition extremely effective. Owing to the high price of fish meal and fish oil, cheaper suitable alternatives are being sought, and species of Spirulina and Chlorella could be a major plant protein source in farmed fish nutrition. Many studies have assessed the suitability of these microalgae in the diet of various fish species. This review highlights the influence of Spirulina on the growth enhancement of different fish species. Numerous beneficial effects of microalgae supplementation have been reported, including growth promotion in carp (Labeo rohita) and tilapia (Oreochromis niloticus), stimulation of immunity in rainbow trout (Oncorhynchus mykiss) and enhancement of reproductive performance in yellowtail cichlid (Pseudotropheus acei). Novel investigations have concluded that Spirulina could be utilized in the treatment of wastewater containing outflow from fish culture activities because of its effectiveness in eliminating heavy metals and metabolising excess feed present in water outflow. The aquaculture industry could integrate the treatment of water outflow with production of Spirulina as an additive to fish diets.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Chlorella sp. and Spirulina (Arthrospira) sp. have the potential to replace fish oil and fish meal in diets, enhancing growth and meat quality, stimulating immunity, and improving the pigmentation in various fish species.

    “Chlorella sp. and Spirulina (Arthrospira) sp. have the potential to replace fish oil and fish meal in diets, enhancing growth and meat quality, stimulating immunity, and improving the pigmentation in various fish species [26,51,52,53,54,55].”
  • Chlorella sp. and Spirulina (Arthrospira) sp. stimulate phagocytosis, increase white blood cell count, and enhance the expression of cytokine genes, playing a crucial role in immune response.

    “More precisely, Chlorella sp. and Spirulina (Arthrospira) sp. stimulate phagocytosis, increase white blood cell count, and enhance the expression of cytokine genes, playing a crucial role in immune response.”
  • Spirulina (Arthrospira) sp. improves reproductive performance by increasing egg production and hatching rates.

    “It also improves reproductive performance by increasing egg production and hatching rates [52].”
  • Spirulina (Arthrospira) sp., rich in carotenoids, enhances pigmentation in fish and neutralizes the toxicity of heavy metals, particularly copper and arsenic.

    “Spirulina (Arthrospira) sp., rich in carotenoids, enhances pigmentation in fish and neutralizes the toxicity of heavy metals, particularly copper and arsenic [51,52,55].”
  • Cultivation of Chlorella sp. and Spirulina (Arthrospira) sp. does not compete with terrestrial crops for arable land, and it can be efficiently carried out using water recirculation or even wastewaters.

    “Notably, their cultivation does not compete with terrestrial crops for arable land, and it can be efficiently carried out using water recirculation or even wastewaters [1,52].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
