Sri Lankan Footprint in Global Aquatic Science Research: A Scientometric Analysis

The present study summarizes the research productivity and international collaboration in aquatic studies conducted by Sri Lankan scholars during 2000-2019. The study was based on the SCOPUS® database. R programming language, package bibliometrix and Vosviewer software were employed in the analysis. Results of the present study indicate that increasing growth trend in the annual number of publications. A significant correlation (p<0.05) between the number of articles and per capita GDP (Gross Domestic Production) was also observed. Senior authors dominated in terms of the article count, citation count, h index, and other author productivity indices. Journal of the National Science Foundation of Sri Lanka had the highest article count (n=33). Aquatic studies in Sri Lanka were more locally funded. Sri Lanka had strong research collaborations with Japan, South Korea and Australia. During 2000-2019, the transition of aquatic studies from lacustrine field studies to molecular lab-based studies were observed. The findings of the present study may provide a comprehensive understanding on the current context and future directions of aquatic studies in Sri Lanka.

Accumulation and distribution of heavy metals in Gerres abbreviatus (Bleeker 1850) and Parastromateus niger (Bloch, 1795) in Kao Bay, North Maluku, Indonesia

Heavy metals have a relationship with fish organs. The aim of this study was to determine the distribution of heavy metals in various organs of Gerres abbreviatus and Parastromateus niger. The research was conducted in Kao Bay waters from April to September 2019. Samples obtained were prepared at the aquatic science laboratory of Khairun University and were analyzed at the Environmental Productivity Laboratory of IPB University Bogor using the AAS instrument to determine heavy metals concentrations. The result of the heavy metals accumulation in Gerres abbreviatus meat was Zn > Cu > Pb > Ni > Hg > Mn > Cd. Meanwhile, the heavy metals accumulation in Roi fish (Parastromateus niger) meat was Zn > Mn > Ni > Hg > Pb > Cd > Cu.

Enriched Agriculture Horticulture Science Technology Socio-EconomyCommunication-Issue by Biomedicines Suppressing Tomato-Disease and Coronavirus 2-Like-Pandemic-Diseases!

To avoid traditional control of root-knot disease, there remains a need for developing effective biomedicines of animal origins. The animal biomedicines; Nematode Extract (NE) and Gall Protein (GP) when applied by foliar spray, are highly effective at 1.3mg/plant and 2.01mg/plant, respectively in ameliorating root-knot disease of tomato (Lycopersicon lycopersicum, Cv. Pusa Ruby) caused by Meloidogyne incognita (Kofoid & White) Chitwood, promoting plant growth and fruit production. The nematode extract (NE) is more effective than the gall protein (GP) in this respect. Both the extract is thought to induce systemic acquired resistance response of the treated plants through the expression of pathogenesis-related proteins, and may prevent 21st –century pandemics COVID-19 like virus diseases by boosting immunity, resisting toxic effects on the environment, and improved agriculture green-socio-economy aquatic-science-technology-communication application issues, and it may also give a good scope for new advanced-development and research in the field “Agricultural, Horticulture, Earth-Environmental-Clinical-Toxicology-Health-Research, Science-Technology-Communication-Socio-Economy and May be Controlled 21st-Century Pandemic Diseases in Future New Normal Situation Also”.
