“…Recently, data analysis using various models has been widely applied for the prediction of HABs, thereby providing a helpful tool for evaluating the relative importance of each factor in outbreak and disappearance processes (Glibert et al 2010;Lane et al 2009;McGillicuddy 2010;Raine et al 2010). However, the mechanism behind the development and decline of an individual bloom event remains incompletely understood despite the numerous studies on the relationship between HABs and environmental factors, such as temperature, light intensity, and inorganic nutrient.…”

A strain O4-6, which had pronounced algicidal effects to the harmful algal bloom causing alga Phaeocystis globosa, was isolated from mangrove sediments in the Yunxiao Mangrove National Nature Reserve, Fujian, China. Based on the 16S rRNA gene sequence and morphological characteristics, the isolate was found to be phylogenetically related to the genus Streptomyces and identified as Streptomyces malaysiensis O4-6. Heat stability, pH tolerance, molecular weight range and aqueous solubility were tested to characterize the algicidal compound secreted from O4-6. Results showed that the algicidal activity of this compound was not heat stable and not affected by pH changes. Residue extracted from the supernatant of O4-6 fermentation broth by ethyl acetate, was purified by Sephadex LH-20 column and silica gel column chromatography before further structure determination. Chemical structure of the responsible compound, named NIG355, was illustrated based on quadrupole time-of-flight mass spectrometry (Q-TOF-MS) and nuclear magnetic resonance (NMR) spectra. And this compound showed a stronger algicidal activity compared with other reported algicides. Furthermore, this article represents the first report of an algicide against P. globosa, and the compound may be potentially used as a bio-agent for controlling harmful algal blooms.

“…Whyte et al (2014) argue that this bloom, and another in 2006, was 87 related to a rapid a change in the dominant mean wind direction around the Shetland Islands where the 88 contaminated shellfish were grown. This hypothesis is supported by research carried out into "wind-89 driven water exchange" onto the southwest Irish shelf and links to recurrent HAB events, including 90 Dinophysis blooms (Raine et al, 2010). These Dinophysis spp.…”

“…Irish south-west coast, an area responsible for 80% of mussels and 50% of oysters in total Irish 93 aquaculture (Raine et al, 2010). Once inside the bay the cells are able to proliferate in toxic blooms 94 which close shellfish harvesting sites for months of the year resulting in inconvenience and economic 95 loss (Raine et al, 2010).…”

Environmental control of harmful dinoflagellates and diatoms in a fjordic system

13Fjordic coastlines provide an ideal protected environment for both finfish and shellfish aquaculture 14 operations. This study reports the results of a cruise to the Scottish Clyde Sea, and associated fjordic 15 were also observed across the cruise transect potentially supporting bloom formation of the 22 mixotrophic D. acuta. Significant spatial variability in phytoplankton that was related to physical 23 characteristics of the water column was observed, with a temperature-driven frontal region at the 24 mouth of Loch Fyne being important in the development of the D. acuta, but not the Chaetoceros 25 bloom. The front also provided significant protection to the aquaculture located within the loch, with 26 neither of the blooms encroaching within it. Analysis based on a particle-tracking model confirms the 27 2 importance of the front to cell transport and shows significant inter-annual differences in advection 28 within the region, that are important to the harmful algal bloom risk therein. 29

“…Raine and McMahon (1998) postulated that its strength off the southwest is determined by the proximity of ISF to the coast. There is growing evidence that the interaction between the ISF, ICC and wind regime drives the dynamics of harmful algal blooms (HABs) a particular burden to the aquaculture industry in the region (Raine et al, 2010). Since the presented model is currently being incorporated into the HAB warning system developed within the scope of the EU FP7 funded ASIMUTH project (www.asimuth.eu) it is important that these typical features are represented.…”
