Spatiotemporal variations in metal accumulation, RNA/DNA ratio and energy reserve in Perna viridis transplanted along a marine pollution gradient in Hong Kong

Determination of microplastics in the edible green-lipped mussel Perna viridis using an automated mapping technique of Raman microspectroscopy

“…Bioaccumulation of xenobiotics in mussels including P. viridis has been widely used for pollution monitoring purposes (e.g. Leung et al, 2011;Pinto et al, 2015;Yeung et al, 2017). As for microplastics, recent studies identified a close alignment between the number of microplastics found in mussels and that in the surrounding water, suggesting the applicability of using mussels in the environmental assessment of microplastics (Qu et al, 2018;Li et al, 2019;Wakkaf et al, 2020).…”

The Genetic Research Methods and its Role in Aquaculture on Indonesia

“…To find out the concentration of DNA and RNA measured by using Gene quant program. Results of DNA and RNA genomic concentrations of each sample were further calculated for determination of RNA-DNA ratio [67][68][69].…”

“…The expression of RNA and DNA content in individual cells could serve as an indicator of the growth rate of the individual, this was because in the cytogenetic theory of the main RNA function as a proteinforming in cells that changes with cell division while the amount and size of DNA in an individual was always constant. Furthermore, the RNA / DNA ratio could be used as an indicator to describe the nutritional quality conditions consumed by aquaculture biota [67,68,95].…”
