This study "Aquatic plants (Azolla filiculoides, Azolla pinnata, Landoltia punctata) and protists, thraustochytrids as renewable and sustainable sources of protein, phenolic, carotenoids and omega-3 fatty acids" provides important information on culturing Azolla (A. filiculoides and A. pinnata), duckweed (L. punctata) and thraustochytrids. It also represents a comprehensive analysis of two Azolla species (A. filiculoides and A. pinnata), one duckweed species (L. punctata) and two new thraustochytrids, all of which are capable of producing valuable biomolecules.

In parallel with these results, the diagrams of Gibbs et al. supported the same seawater intrusion phenomena. Brackish karst springs first roseand then fell below sea level with epirogenic movements during the geological period, and therefore, karstification progressed. The samples were oversaturated with calcite, dolomite, and quartz, whereas they were undersaturated with gypsum and halite. The Al, Cu, and Zn values of some of the water samples exceeded the tolerance limit of aquatic life standards.

The main objective of this study was to confirm and estimate the algal inhibiting effects of the ethanol and ethyl acetate E. fortunei extracts at concentrations of 500 mg.L- in some natural water samples collected from Hoan Kiem and Lang Lakes. The results of this work may be useful for controlling the toxic cyanobacterium bloom in natural aquatic ecosystem.

Aquaculture, also known as aquafarming, is the farming of aquatic organisms such as fish, crustaceans, molluscs and aquatic plants.[1][2] Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish.[3] Mariculture refers to aquaculture practiced in marine environments and in underwater habitats.

Wetland can be understood as an ecological system lie on a continuum between uplands, where excessive water is not a factor for plant growth, and deeply flooded lands, or aquatic systems, where flooding excludes rooted emergent vegetation. Figure 1 shows how to describe this wetland concept
