“…Figure 1 depicts the various types of seaweeds. Seaweeds have evolved to either be attached to hard substrates, such as rocks, with the help of special root-like organs known as holdfasts, or be free-floating [25]. As highlighted above, seaweeds are a good source of essential nutrients such as proteins, vitamins, minerals, and bioactive compounds.…”

Seaweed, also known as macroalgae, represents a vast resource that can be categorized into three taxonomic groups: Rhodophyta (red), Chlorophyta (green), and Phaeophyceae (brown). They are a good source of essential nutrients such as proteins, minerals, vitamins, and omega-3 fatty acids. Seaweed also contains a wide range of functional metabolites, including polyphenols, polysaccharides, and pigments. This study comprehensively discusses seaweed and seaweed-derived metabolites and their potential as a functional feed ingredient in aquafeed for aquaculture production. Past research has discussed the nutritional role of seaweed in promoting the growth performance of fish, but their effects on immune response and gut health in fish have received considerably less attention in the published literature. Existing research, however, has demonstrated that dietary seaweed and seaweed-based metabolite supplementation positively impact the antioxidant status, disease resistance, and stress response in fish. Additionally, seaweed supplementation can promote the growth of beneficial bacteria and inhibit the proliferation of harmful bacteria, thereby improving gut health and nutrient absorption in fish. Nevertheless, an important balance remains between dietary seaweed inclusion level and the resultant metabolic alteration in fish. This review highlights the current state of knowledge and the associated importance of continued research endeavors regarding seaweed and seaweed-based functional metabolites as potential modulators of growth, immune and antioxidant response, and gut microbiota composition in fish.

“…Blades are primary photosynthetic leaflike flattened parts that absorb sunlight. Furthermore, thallus refers to the fundamental or advanced body-like structure of seaweeds that can conduct photosynthesis with all its parts (Figure 1) (Suryanarayana Murty & Banerjee, 2011;Baweja et al, 2016;Sudhakar et al, 2018).…”

Seaweeds, also known as macroalgae, are abundant sources of various vital bioactive components with a wide range of biological functions. They are sold commercially and are primarily used in the food industry, pharmaceuticals, cosmeceuticals, and other related industries. The diverse biological activities linked with bioactive compounds obtained from seaweeds have the potential to expand their health benefit value in the food and pharmaceutical industries. Studies revealed that seaweeds have the potential to be used as complementary medicine due to its variety of biological properties that have been shown to be therapeutic for health and disease management, such as antibacterial, anticoagulant, anticancer, antidiabetic, antiestrogenic, antihypertensive, antihyperlipidemic, antifungal, anti-inflammatory, antioxidant, antiobesity, antiviral, immunomodulatory, neuroprotective, thyroid stimulant, tissue healing properties, and many more. Although seaweeds are generally beneficial to humans, they may still pose possible health risks due to high iodine concentration and exposure to heavy metals and arsenic concentrations. However, information on this topic is still limited. With the great importance of seaweeds, various green extraction methods such as Microwave-assisted Extraction (MAE), Supercritical Fluid Extraction (SFE), Pressurized Solvents Extraction (PSE) and Enzyme-ssisted Extraction (EAE) were used as an alternative to the conventional method to isolate bioactive components and further purified using chromatographic technique analysis to ensure the purity of the extract. This review covers the following topics: general structure and characteristics of seaweeds, seaweed production, bioactive components and properties of seaweed, possible risk factors of seaweeds, applications of seaweeds, extraction, and purification of seaweed extracts.
