Culture conditions like pH, temperature and salinity, optimized in f/2 medium revealed that pH 9, temperature 20°C and salinity 25 ppt were found to yield optimum output. Estimation of biochemical constituents showed more lipid content in the stationary phase, indicating the right harvesting time and this live feed organisms can also be considered for biofuel in the future.","PeriodicalId":93791,"journal":{"name":"Journal of the Marine Biological Association of India.

A remarkable number of studies exist regarding the etiological, microbiological, and ecological characteristics and extent of this widely studied disease. This bibliometric study comprehends the global literature published on BBD and aims to assess the research activities and trends on BBD using the Bibliometrix R-package. Authors, countries, institutions, core journals, thematic maps, and historic direct citation networks are analyzed. Assessment of author productivity summarizes that the majority of the scientific literature emanated from a smaller group of researchers, with 70% of authors contributing only single articles. The prominent collaboration in global BBD research is a trio between the USA, UK, and Australia. This indicates that research requires more focus and fostering in many developing countries, and this needs further active research collaborations with the developing countries. Co-occurrence networks and Co-citation networks outlined the most strongly related words, authors, papers, and sources. Thematic map reveals BBD research revolves around the basic themes such as “disease prevalence”, but currently, interest has been shifted towards specialized themes like “microbial community”. The focus of the majority of the researchers was on the abundance, prevalence, and spatio-temporal dynamics of BBD. Molecular and genetic level studies of the microbial communities that involve metagenomics approaches are ongoing and active. The specialized or niche themes such as microbial consortium, the shift in the microbiome, and the presence of quorum sensing inhibitors in this consortium are acquiring much interest. Analysis of BBD publications indicates that treatment methods, resistance, and coral immunity against BBD were some of the under-looked areas in the research. This bibliometric report provides a nutshell of the status of global BBD research that can act as a reference for and guidance to the coral scientists, research funders, and policymakers to tackle BBD.","PeriodicalId":93791,"journal":{"name":"Journal of the Marine Biological Association of India.

No conspicuous colouration of the surface waters was noticed even with the higher abundance of (1.7 x 106 cells L-1) observed near the barmouth area (6-7 m). The tracking on the occurrence of this genus in this region from 2013 to 2019 revealed their occurrence only during three times over the six years, i.e. the post monsoon season of 2013 and 2014 and during pre-monsoon of 2016. The SST of the three stations of the post monsoon season was compared for the last three years from 2017 to 2019, and an evident variation in the SST distribution was noticed in this region. The SST in 2019 was 2.1°C higher than that observed during 2017. The occurrence of Ornithocercus magnificus showed a positive correlation with SST (rs =0.425, p<0.05). It was also noted that the occurrence of this species was observed during the El Nino years. The Oceanic Nino Index (ONI) also positively correlated with the SST during the period (rs =0.432, p<0.05). The higher abundance of this species in 2019 when warmer SST was observed and their positive correlation with SST indicates the preferences of O.magnificus to warmer waters. The Shannon and Weiner diversity index (H’) ranged from 2.87-3.29 and the water quality index (WQI) remained good during the bloom. As Ornithocercus magnificus did occur during higher SST, this genus can be used as a proxy of climate change and hence has a strong potential to be used as indicator species of higher SST variation if found in novel environments.","PeriodicalId":93791,"journal":{"name":"Journal of the Marine Biological Association of India.

The samples were analysed both qualitatively and quantitatively by adopting standard methods. 23 groups of zooplankton were recorded from the study area. Out of these, a maximum of 18 groups were recorded from station 1 (Cochin bar mouth) and a minimum of 9 groups from station 6 (Kottappuram). Overall average density of zooplankton in the study area was 3044 numbers per 100 m3 . Station-wise studies indicated that the average zooplankton density was maximum (4882 per 100 m3 ) at station 2 (Kadamakudy) and minimum (1649 per 100 m3 ) at station 5 (Azhikode bar mouth). Among the different groups of zooplankton in the study area, a maximum of 79% was contributed by copepods, 14% by rotifers while the remaining groups contributed less than 2% each. Month-wise analysis indicated the maximum density during September and the minimum during January. Biodiversity analyses were carried out by Primer v. 6 software. From the cluster analysis and Bray-Curtis similarity matrix, July and August months showed the maximum similarity of species composition compared to all other months.","PeriodicalId":93791,"journal":{"name":"Journal of the Marine Biological Association of India.

The status of the physicochemical and biological aspects indicating the healthiness of selected seagrass and mangrove habitats of Tuticorin coast was studied during 2013-15. The water and sediment quality parameters and the benthic in-faunal constituents were assessed monthly adopting the standard procedures. Our study indicated that the mangrove habitat was profoundly impacted due to the influence of high saline effluents from neighbouring salt pans. The mean values of most of the water quality parameters like salinity (37.87±1.86ppt); chlorophyll-a (8.2±2.95mg.m-3); TSS (529.6±47.13mg.L-1) ammonia (0.12±0.02µg.L-1); nitrite (1.96±0.92µg.L-1); phosphate (8.67±2.58µg.L-1) were reported abnormal from the mangrove habitats. The seagrass habitat was impacted mainly by the activities of the neighbouring port, causing comparatively higher total suspended solids and dissolved solids in the water. Parameters like, DO, salinity, chlorophyll, TSS, NH3 , NO2 , SiO3 in seawater and coarse and fine sand proportions of sediments were significantly varied between habitats (p<0.05). The lower density and less diverse in-faunal constituents also proved the harshness of the sediments of both the habitats. The study also warrants the need for effective management strategies for conservation and the sustainable utilisation of these resources.","PeriodicalId":93791,"journal":{"name":"Journal of the Marine Biological Association of India.
