“…Prawn releases have occurred for over 50 years in various countries, at large scales in China and Japan, but also in Kuwait, United States, Taiwan, Australia and Sri Lanka ( Davenport et al, 1999 ; Loneragan et al, 2006 ; Setio, 2016 ) resulting in varying levels of success ( Kitada, 2018 ; Serajuddin et al, 2018 ; Kitada, 2020 ). Highly variable and low recapture rates were reported from several prawn stock enhancement programs in Japan where in the majority of cases stocked prawns represented 2% or less of the catch and only two cases exceeded 10% recapture rate ( Hamasaki and Kitada, 2006 ).…”

Eastern king prawn (Penaeus plebejus) is endemic to eastern Australia and is of high commercial and recreational value. As part of a recreational fisheries enhancement initiative, hatchery reared juveniles from Queensland were released into two, more Southern New South Wales (NSW) estuaries between 2014 and 2015. Responsible stock enhancement programs rely on knowledge of the population structure of the released species. Previously, in consideration of fisheries data, it was assumed the king prawn populations in Australia are one single breeding stock. In the present study, our first aim was to test this posit of no genetic differentiation using mtDNA control region (mtCR) sequences from the wild samples collected from four estuaries ranging from Queensland/NSW border (source of the stocked animals) to Southern NSW. The second objective was to test for signals of hatchery-released animals in the two stocked estuaries. All four surveyed populations had an extremely high level of haplotype diversity (average h = 99.8%) and low level of haplotype sharing between populations. Estimates of PhiPT values were <0.01 or close to zero and AMOVA test did not indicate any significant differences among populations. Further, phylogenetic analysis and principal coordinate analysis did not support division of samples by population. Collectively these results suggest that eastern king prawn populations along the NSW coast can be considered as a single stock and stocking from the Queensland samples will not necessarily impact the genetic composition of the overall stock. After stocking of two estuaries, sharing of haplotypes was moderate to very high in the stocked sites (>80% in some collections) but negligible in the two unstocked estuaries (≤2%, which is assumed to be background coancestry unrelated to the hatchery). Moreover, some haplotypes present in the hatchery broodstock were detected in stocked sites, but not in unstocked sites. The highest stocking signal was detected in the estuary which becomes isolated from the sea by sand barrier suggesting such “lakes” maybe more favourable for stocking than estuaries directly open to the sea. Findings in the current study should assist in designing and implementation of future prawn stocking programs.

Rasashastra, an Ayurvedic pharmaceutical branch, scientifically converts natural resources into palatable therapeutic dosage forms. Ayurvedic Marine Drugs (AMD) are mainly calcium carbonate/ calcite, but in Ayurvedic treatment modality they are uniquely used for several ailments. Moreover, their detailed microchemical compositions have seldom been reported. In this study, five raw materials, conch, oyster shell, cowry, coral, and pearl, their transitions during the manufacturing process, and the final drugs were analyzed for identification and quantitation of minor elements using a validated inductively coupled plasma optical emission spectrophotometry method. All the five raw materials contained traces of Al, Ag, B, Ba, Cu, Co, Cr, Fe, Hg, Li, K, Mg, Mn, Na, Ni, Pb, S, Sr, Tl, and Zn. Interestingly, B, Co, Cr, Li, Mn, and Ni were absent in the finished products, whereas Pb and Hg exhibited a considerable decrement during the drug formation. The first three components of principal component analysis together explained 72.09% of variance. Raw AMD indicated positive factor scores, whereas their respective purified and incinerated forms exhibited negative scores. Cluster analysis derived a dendrogram typically forming incinerated AMD group but not for the raw forms. Coral with Mg as highest content was a remarkable outlier in both these analyses as compared to Na in others. In discriminant analysis of the presence/absence of elements and periodic table-based classifications, coral and pearl showed higher variation indicating as discriminants when equated with others. Periodic table-based classification was a better model for discrimination. Correlation analysis in both classifications revealed a strong correlation of conch with oyster shells and vice versa, cowry and pearl with oyster shell and a weak correlation of coral with pearl. Coral was a good predictor followed by conch, pearl, oyster shell, and cowry, sequentially, and can be considered a moderately sensitive but highly specific model. Thus, ICP-OES technique is highly precise and accurate for assessing the micro-composition of raw, in-process, and finished products to ensure their transitions, quality, and genuineness. Such characterized traditional medicines should be further investigated in depth for their mechanistic aspects. Graphical abstract
