“…(especially CRM and CC), followed by S. longigolium , G. corticata, and G. indica (Table ), which reveals the potential of tropical selected seaweeds to be used as nutritional resources. Amino acid profiling of seaweeds, collected from Norwegian waters was performed to explore their commercial potential (Biancarosa et al, ; Gaillard et al, ; Tayyab, Novoa‐Garrido, Roleda, Lind, & Weisbjerg, ). In a recent study, it was demonstrated that amino acid composition varied with seaweed species, habitat, and harvesting time; however, amino acid digestion was only affected by species (Gaillard et al, ; Tayyab et al, ).…”

Seaweeds are a rich source of metabolites, including polyphenols, flavonoid, and amino acids, and have been used as food or food supplements in Asian countries since ancient times. Different metabolites are being reported from seaweeds worldwide, but there has been little reported, so far, on tropical seaweeds of the Arabian Sea coast. Eighteen abundant tropical seaweeds (7 green, 4 brown, and 7 red) were collected from the Saurashtra Coast of the Arabian Sea (Gujarat, India), and their phenolic, flavonoid, and amino acid compositions were studied. Liquid chromatography/mass spectroscopy revealed the presence of important polyphenols and flavonoids. High‐performance liquid chromatography detected ascorbic acid and 19 natural flavonoids, including gallic acid, catechins, myricetin, proanthocyanin, kaempferol, quercetin, apigenin, and lutein. The highest amount of ascorbic acid (26.3 mg/g DW) was detected in Ulva fasciata, followed by Ulva lactuca (20 mg/g DW) and Grateloupia indica (11.5 mg/g DW). All green and red seaweeds contained gallic acid, with the highest amount (9 mg/g DW) in Amphiroa anceps, followed by Caulerpa racemosa var. macrophysa (8.5 mg/g DW) and Caulerpa corynephora (4 mg/g DW). The highest catechin content was found in A. anceps (14 mg/g DW), followed by C. racemosa var. macrophysa and Spatoglossum asperum (11 mg/g DW). Amino acids are primary metabolites that are important in the human diet. Among the green seaweeds, the highest amounts of leucine (0.2 mg/g protein), lysine (0.5 mg/g protein), methionine (0.4 mg/g protein), phenylalanine (0.2 mg/g protein), valine (1.3 mg/g protein), proline (48 mg/g protein), and tyrosine (28 mg/g protein) were detected in Caulerpa spp. The highest amounts of the sulfur‐rich amino acids, methionine (1 mg/g protein), and cysteine (9 mg/g protein), were found in the red seaweed Gracilaria corticata. This study reveals that tropical seaweeds, including Caulerpa spp., Spatoglossum asperum, Stoechospermum polypodioides, Gracilaria corticata, and Grateloupia indica, are promising as functional food ingredients or dietary supplements for daily intake. Practical applications The present study demonstrates that tropical seaweeds, especially Caulerpa species (corynephora, racemosa and chemnitzia), S. asperum, S. polypodioides, G. corticata, and G. indica are rich source of phenolic and flavonoid compounds, including ascorbic acid, gallic acid, catechins, myricetin, proanthocyanin, and essential amino acids. These metabolites are natural antioxidants and own high bioactivity. The article reveals the functional food or nutraceutical potential of tropical seaweeds. As practical perspective, tropical seaweeds such as Caulerpa has potential to be processed further as a functional food or may be explored for the extraction of nutraceuticals.

“…Another important limitation of some in vivo protocols is the requirement for the ruminal and duodenal fistulation of the animal, which is problematic both for welfare reasons and because the samples taken by cannula are sometimes not representative and microbial contamination is inevitable during handling (Seymour et al, 1992). The in situ protein degradation method was developed to avoid the sources of error inherent in the in vivo method as it consists of the intra-ruminal incubation of dacron bags containing feed (Mehrez and Ørskov, 1977;Ørskov, 1992;Shannak et al, 2000;Pawelek et al, 2008;Zhang et al, 2015;Tayyab et al, 2016). This technique is one of the most traditional and representative for studying the proteolysis dynamics in the rumen.…”

Empirical Attributes and Limitations of Methodologies for Predicting the Degradability of Ruminal Protein

present review is to analyze the methodologies that are commonly used to estimate protein degradability in the rumen, focusing on their attributes and limitations to offer suggestions for improving their use. This information is essential for selecting food types when formulating feed diets. A reliable prediction of the digestibility of ruminal proteins is basic information necessary for optimizing the use of nitrogenous sources because digestibility can translate, on the one hand, into higher yields of milk, milk protein, meat or wool and, on the other hand, into lower excretion of nitrogenous compounds into the environment; it also has an impact on animal health and welfare. Traditionally, the digestibility of feed proteins in the rumen has been predicted by in vivo, in situ and in vitro methods, but other techniques based on infrared spectroscopy have been developed, notably the NIRS and FTIR methods. All of these techniques present limitations, such as a disturbance factor or a source of error, that may result in inaccurate predictions. The in situ and in vitro methods, which use enzyme extracts of ruminal origin, and FTIR probably have the greatest advantages, but they need to be perfected through further research.

“…Cultivated seaweed provide distinguished advantages over other cultivated biomasses: they require little or no arable land, fertilisers or fresh water (Subhadra and Edwards 2010; John et al 2011; Wei et al 2013) while providing a variety of other ecosystem services, including nutrient bioremediation (Chung et al 2002) and possibly habitat provision (Phillips 1990). Seaweed biomass shows promising potential as a material in the production of biofuels, fertiliser, materials, chemicals, feed and food (Jung et al 2013; van Hal et al 2014; Chapman et al 2015; Pechsiri et al 2016; Tayyab et al 2016; Molina-Alcaide et al 2017). Coupled with a significant projected growth in the fisheries sector to meet a growing demand for protein (OECD/FAO 2015) and calls for the development of marine biomass within the blue growth initiative to support more sustainable bio-based economies (EU Commission 2012), the coming decades are likely to see significant increases in the development of off- and near-shore production systems, not just of seaweed, but also of fish, crustaceans and molluscs.…”

Efforts are on the way on the Swedish West Coast to develop the capacity for cultivation of marine resources, notably of kelps. Given that this is a region of great natural and national heritage, public opposition to marine developments has been identified as a possible risk factor. This survey thus sought to shed light on awareness levels, perceptions of different types of aquaculture and on reactions to a scenario depicting future aquaculture developments on the West Coast. When asked about their general opinions of aquaculture, respondents tended to be favourable though a majority chose neutral responses. On the whole, respondents were favourable to the depicted scenario. Finally, it was found that the high-awareness group tended to be more supportive than the low or medium-awareness groups, hinting at the benefits of increasing awareness to reduce public aversion and to support a sustainable development of aquaculture on the Swedish West Coast.Electronic supplementary materialThe online version of this article (doi:10.1007/s13280-017-0945-3) contains supplementary material, which is available to authorized users.
