Macroalgae, commonly known as seaweed, offer a novel and added-value dietary ingredient in formulated diets for fish. Production of biomass can be achieved without reliance on expensive arable land, as seaweed may be collected from coastal regions or farmed. There are three taxonomic groups represented by the term 'macroalgae': Rhodophyta (red), Chlorophyta (green) and Phaeophyta (brown). Like terrestrial plants, nutritional content in macroalgae can vary greatly amongst species, genera, divisions, seasons and locations. Aside from their basic nutritional value, seaweeds contain a number of pigments, defensive and storage compounds, and secondary metabolites that could have beneficial effects on farmed fish. This review appraises the beneficial qualities of these macroalgae compounds and their potential for exploitation in commercial finfish feeds. The current knowledge of the effects of macroalgae inclusion in finfish diets is also addressed. From these >50 fish feeding studies that were analysed, enhancing trends in fish growth, physiology, stress resistance, immune system and fillet muscle quality were reported. However, only a small fraction of algal species have so far been investigated as potential components in finfish diets, and furthermore, this review has identified a number of knowledge gaps that current research has yet to address. To conclude, an appraisal is made of the possible technologies employed to exploit seaweeds to an industrial level through stabilising the algal meal, enhancing the digestibility and functional food properties.

“…The results were promising as laboratory animals have been shown to have increased numbers of Bifidobacterium and Lactobacillus (Kuda and others ; Hu and others ; Wang and others ). Other parameters indicating a prebiotic activity are the pH of the cecal content, organic acid concentrations, and fecal weight (Wang and others ; Ishihara and others ). To be considered prebiotic, a compound must possess 3 criteria: first, it must not be digested in the upper gastrointestinal tract (GIT); second, it must be a selective substrate for the growth of beneficial bacteria; and, third, it must have beneficial effect on the host's health.…”

The significance of marine creatures as a source of unique bioactive compounds is expanding. Marine organisms constitue nearly half of the wordwide biodiversity; thus, oceans and sea present a vast resource for new substances and it is considered the largest remaining reservoir of beneficial natural molecules that maight be used as functional constituents in the food sector. This review is an update to the information about recent functional seafood compounds (proteins, peptides, amino acids, fatty acids, sterols, polysaccharides, oligosaccharides, phenolic compounds, photosynthetic pigments, vitamins, and minerals) focusing on their potential use and health benefits.

“…Glycerol galactoside (GG; floridoside, 2-O-glycerol-α-Dgalactopyranoside; isofloridoside, 1-O-glycerol-α-D-galactopyranoside), a component found in red seaweed nori, significantly increases the number of Lactobacillus in the intestinal tract of mice. 63 Both GG and fructooligosaccharide (FOS) diets significantly increase the number of Bifidobacterium without changing the total number of Enterococcus and Clostridium sphaeroides. In addition, low-molecular-weight seaweed extracts can be used by the intestinal microbiota, which significantly increases the content of acetate and propionate of in vitro fecal fermentation broths.…”

One strategy to achieve a balanced intestinal microbiota is to introduce prebiotics. Some substances present in the diet, such as soybean extracts, koji glycosylceramides, grape extracts, tea polyphenols, and seaweed extracts, can be considered as potential prebiotics, because they can selectively stimulate the proliferation of beneficial bacteria in the intestine. However, the discovery of novel prebiotics also involves advances in screening methods and the use of thermal and non-thermal processing techniques to modify and enhance the properties of beneficial organisms. The health benefits of prebiotics are also reflected by their participation in regulating the microbiota in different gut axes. In the present review, we introduced the field of prebiotics, focusing on potential prebiotic substances, the process of screening potential prebiotics, the transformation of prebiotics by food-processing technologies, and the roles of prebiotics on gut axis regulation, which, it is hoped, will promote the discovery and utilization of novel prebiotics.
