Aquaculture systems may release large amounts of nutrients into the marine ecosystem that can lead to eutrophication. Many seaweed species are efficient in reducing the nutrient concentration in aquaculture waste. In this study, the agarophyte Gelidium elegans originating from Korea was investigated for bioremediation of tiger shrimp (Penaeus monodon) broodstock effluent (SBE) in a shrimp hatch...

Spent biomass of different seaweeds such as Sargassum wightii, Turbinaria conoides, Padina tetrastomata and Ulva lactuca were evaluated for the nutritional benefits in aqua feeds. Basic nutritional value, of seaweeds contains a number of pigments, defensive and storage compounds, and secondary metabolites that could have beneficial effects in farmed fish. Only a small fraction of algal species ...

this study was conducted to investigate the effects of using gracilariopsis persica in layer diet on performance, egg quality and lipids of blood serum of layer hens. one-hundred hy-line w-36 hens were allocated to five dietary treatments (experimental diets containing 0, 5, 10, 15 and 20 percent seaweed) and five replicates and four birds in each for 12 week period (23-34 week of age). the res...

Early theories of species diversity proposed that communities at equilibrium are saturated with species. However, experiments in plant communities suggest that many communities are unsaturated and species richness can be increased by adding propagules of new species. We experimentally tested for community saturation and measured the effects of propagule supply on community structure in a benthi...

Background: The life-style-related diseases, like hypertension and obesity is a global tendency. To prevent these diseases, researchers’ attention is increasingly focusing on pharmacological properties of some natural plants such as Undaria pinnatifida (wakame), the most widely eaten brown seaweed. Phytochemical studies of this seaweed exhibited the existence of many biologically active compoun...

BACKGROUND: Biofertilizers, like amino acids, are used to reduce drought stress damage to plants and improve physiological factors, thereby increasing plant yield in arid and semi-arid regions. Seaweed extract has a beneficial effect on plant growth due to its growth hormones and elements such as iron, copper, zinc, cobalt, molybdenum, manganese and nickel, vitamins and amino a...

Natural sulfated polysaccharides (SPs) derived from brown seaweed comprise a complex group of macromolecules with a wide range of important physiological properties. SPs have been shown to bind and directly regulate the bioactivity of growth factors and cytokines such as basic fibroblast growth factor, interferon, various enzymes and transforming growth factor. Myostatin is a member of the tran...
