“…a). Due to excitation of surface plasmon vibration in metal nanoparticles, silver nanoparticles exhibit yellowish‐brown colour in the water (Veerasamy, Xin, Gunasagaran, Xiang, Yang & Jeyakumar ; Namratha & Monica Sharma, Rather, Ajima, Gireesh, Kumar & Sharma ). UV–Vis absorption spectrum of G‐AgNPs in the presence of neem leaf extract is shown in Fig.…”

Green synthesis of nanoparticles by using different biological agents has emerged as an alternative to overcome the toxic effect of chemically synthesized nanoparticles. Among various biological agents, plants are mostly preferred. This study describes an eco‐friendly and green synthesis of silver nanoparticles (G‐AgNPs) using Azadirachta indica (neem) as a reducing agent. UV–Vis spectral analysis proved the wavelength of sample to be 420 nm, approaching the surface resonance peak specific for G‐AgNPs. Dynamic light scattering (DLS) analysis showed the mean diameter of particles as 35.4 nm with zeta potential +34.6 mV. TEM results revealed the compact and spherical shape of the particles. Fourier transform infrared spectroscopies (FT‐IR) demonstrate the presence of possible functional groups involved in synthesis of the silver nanoparticles. The functional activity of immunological parameters, such as nitroblue tetrazolium assay, myeloperoxidase activity, phagocytic activity, anti‐protease and lysozyme activity, increased significantly (P < 0.05) in fish treated with G‐AgNPs. Relative percentage survival (74%) and enhanced disease resistance were observed in G‐AgNP‐treated Cirrhinus mrigala fingerlings challenged with Aeromonas hydrophila. In summary, present results demonstrate biosynthesized silver nanoparticles have immunomodulatory and antibacterial activity.

“…Sex determination in tilapia species is mainly genetic, although environmental factors also play a role [17], [18]. Identifying of advantageous genes like growth-related genes, disease-related gene, sex determination, sex differentiation, reproductive gene and physiological gene is a key step in aquaculture that will optimized for greater yield, cost-efficiency, quality, and disease resistance [19], [20], [21], [22]…”

“…Furthermore, the lysosomal membrane stability is a stress biomarker, and, in this case, the neutral red activation retention assay is used to measure the increased lysosomal contents in the cytosol as a response to the increased ROS amount [128]. ROS can also cause DNA damage, including strand breaks, mutations, chromosomal aberration [177] and even cell death [178]. DNA strand breaks and mutagenicity endpoints are determined using chromosome aberrations and micronucleus assays [179].…”

In the last decade, metal engineered nanomaterials (ENMs) have seen an exponential use in many critical technologies and products, as well an increasing release into the environment. Coastal ecosystems worldwide may receive ENM-polluted waters and wastes, with a consequent alteration of habitats and contamination of aquatic biota. There is a scarcity of data regarding the fate of these emerging contaminants in such environments. Open issues include the determination of the sources, the quantification of the interactions with marine sediments, the bioaccumulation pathways, the ecotoxicology on marine fauna and the identification of the principal biotic and abiotic factors that may alter metal ENMs toxicity. Little is known about their potential transference into the food web, as well toxicity features and co-stressors of single or multiple ENMs under laboratory and real environmental conditions for various taxonomic phyla. This review reports current knowledge on the ecological impact of ENMs under the complex environmental conditions of estuary systems, identifies gaps in current knowledge and provides directions for future research.
