“…Some species of the Ludwigia genus show promising sources of anticancer phytochemicals [ 30 ] and antioxidants [ 30 , 31 , 32 ], with antibacterial [ 31 , 32 , 33 ] and antifungal activity [ 34 ]. However, no studies have been reported showing the insecticidal potential of this genus.…”

We tested the bioactivity of aqueous extracts of Ludwigia spp. (Myrtales: Onagraceae) on the biological cycle of Plutella xylostella. We assessed the duration of and viability during the larval, pupal and adult phases, as well as the influence of the extracts on the fecundity and hatching of P. xylostella eggs. Subsequently, we phytochemically screened the extracts. The extracts of L. tomentosa and L. longifolia reduced the pupal weight instead of prolonging the larval stage of P. xylostella. The L. tomentosa effect caused higher larval mortality and reduced the fecundity and hatching of P. xylostella eggs, and L. sericea reduced the egg survival. The phenolic compounds—flavonoids, condensed tannins and alkaloids—were more abundant in L. nervosa, L. tomentosa, L. sericea and L. longifolia. The L. tomentosa, L. longifolia and L. sericea extracts were bioactive, and these species showed the best results regarding their ability to control P. xylostella populations, because these plants produce substances able to inhibit food consumption and interfere with the morphological and physiological transformations of the offspring and the oviposition of adults.

“…The standard food chart recommended 30 g of fish or meat protein for daily food intake [11], which is unlikely to be achieved soon with present pace of fisheries development in Nepal. Thus, more emphasis should be given to enhance the domestic fish production.…”

Role of inland fishery and aquaculture for food and nutrition security in Nepal

Fish as a food is generally acceptable to all regardless of region, religion, race, gender and age across Nepal. The aquaculture and open-water capture fishery contributes about 2 % of agricultural gross domestic production; this share of fisheries sector is tiny but promising having a fastest 8-9 % annual growth rate. Nevertheless, the contribution of fisheries sector is big from nutritional security perspective to poor and marginalized communities and thus cannot be ignored. Generally, the role and importance of the inland water fisheries had been rarely elaborated with perspectives to food and nutritional security in Himalayan landlocked country. Therefore, the aim of this paper was to elucidate the role and potential of inland fisheries for food and nutrition security in Nepal. Information was collected from secondary sources to estimate per capita fish consumption. The per capita consumption was calculated dividing the total fish production by population of specific year, which showed that per capita fish consumption has increased from 125 g in 1975 to 2060 g in year 2013, at least nine times below compared with average global consumption. The value of per capita fish consumption would increase, if native shellfish (gastropod, crab, shrimp, and turtle), frogs and aquatic plants such as foxnut (Euryale ferox) and water chest nut (Trapa sp) which are consumed by ethnic communities are added. In the fish production among the five development regions of the country, Central Development Region was at the top, while Far-Western Development Region was at the bottom. However, on altitudinal basis southern plains contribute highest production, while least is in mountain areas although potentiality of cold-water aquaculture seems high. These imply that support services and innovation should be extended in the Western Development Region and mountainous regions in addition to the plains for improving fisheries-based food and nutrition security.

“…By contrast, the importance of freshwater macrophytes in this aspect has often been overlooked [ 3 ]. However, the existing evidence favors the view that naturally occurring compounds from aquatic ecosystems are of particular interest since many of them display important biological activities and possess antitumor, antibacterial, antimicrobial, antifouling, antifungal, pesticidal, phototoxic, HIV-inhibitory, and immunosuppressive properties [ 4 ].…”

“…At present the component (chemical) composition of essential oils extracted from several species of aquatic macrophytes growing on the territory of Russia has been identified, and constituent patterns related to biosynthesis of VOCs in freshwater ecosystems have been revealed [ 6 ]. Recently close attention has been paid to freshwater macrophytes as they can be a source of anticancer and antioxidative natural products [ 3 ].…”

Assessment of the Potential Biological Activity of Low Molecular Weight Metabolites of Freshwater Macrophytes with QSAR

et al. 2016

The paper focuses on the assessment of the spectrum of biological activities (antineoplastic, anti-inflammatory, antifungal, and antibacterial) with PASS (Prediction of Activity Spectra for Substances) for the major components of three macrophytes widespread in the Holarctic species of freshwater, emergent macrophyte with floating leaves, Nuphar lutea (L.) Sm., and two species of submergent macrophyte groups, Ceratophyllum demersum L. and Potamogeton obtusifolius (Mert. et Koch), for the discovery of their ecological and pharmacological potential. The predicted probability of anti-inflammatory or antineoplastic activities above 0.8 was observed for twenty compounds. The same compounds were also characterized by high probability of antifungal and antibacterial activity. Six metabolites, namely, hexanal, pentadecanal, tetradecanoic acid, dibutyl phthalate, hexadecanoic acid, and manool, were a part of the major components of all three studied plants, indicating their high ecological significance and a certain universalism in their use by various species of water plants for the implementation of ecological and biochemical functions. This report underlines the role of identified compounds not only as important components in regulation of biochemical and metabolic pathways and processes in aquatic ecological systems, but also as potential pharmacological agents in the fight against different diseases.
