    • Effect of chrysophanic acid on immune response and immune genes transcriptomic profile in Catla catla against Aeromonas hydrophila 

      Harikrishnan, Ramasamy; Devi, Gunapathy; Balasundaram, Chellam; Van Doan, Hien; Jaturasitha, Sanchai; Ringø, Einar; Faggio, Caterina (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-12)
      The effect of chrysophanic acid (CA) (2, 4, and 8 mg kg<sup>−1</sup>) on the immunity and immune-related gene profile of Catla catla against Aeromonas hydrophila is reported. In both control and treated groups fed with 2 mg kg<sup>−1</sup> (2 CA), the phagocytosis, hemolytic, myeloperoxidase content, and superoxide anion production decreased significantly between 6th and 8th weeks, whereas when fed ...

    • The Effect of Gut Microbiota and Probiotics on Metabolism in Fish and Shrimp 

      Ringø, Einar; Harikrishnan, Ramasamy; Soltani, Mehdi; Ghosh, Koushik (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-03)
      The present paper presents an overview of the effects of gut microbiota and probiotics on lipid-, carbohydrate-, protein- and amino acid metabolism in fish and shrimp. In probiotic fish studies, the zebrafish (Danio rerio) model is the most frequently used, and probiotic administration reveals the effect on glucose homeostasis, anti-lipidemic effects and increasing short-chain fatty acids, and ...

    • Fungi and Actinobacteria: Alternative Probiotics for Sustainable Aquaculture 

      Ghosh, Koushik; Harikrishnan, Ramasamy; Mukhopadhyay, Abhisek; Ringø, Einar (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-25)
      Aquatic animals are continually being exposed to stressors under farming conditions, increasing risks to gut health that result in dysbiosis. Since restrictions are imposed on the frequent use of antibiotics in aquaculture, there is emerging demand for economically viable, environmentally safe, and sustainable alternatives for the intensive production of aquaculture species. The application ...

    • Sustainable Ornamental Fish Aquaculture: The Implication of Microbial Feed Additives 

      Hoseinifar, Seyed Hossein; Maradonna, Francesca; Faheem, Mehwish; Harikrishnan, Ramasamy; Devi, Gunapathy; Ringø, Einar; Van Doan, Hien; Ashouri, Ghasem; Gioacchini, Giorgia; Carnevali, Oliana (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-09)
      Ornamental fish trade represents an important economic sector with an export turnover that reached approximately 5 billion US dollars in 2018. Despite its high economic importance, this sector does not receive much attention. Ornamental fish husbandry still faces many challenges and losses caused by transport stress and handling and outbreak of diseases are still to be improved. This review will ...
