“…However, the method is accurate and is therefore applied as one of the detailed sample analysis methods for laboratory applications including type approval tests of BWMS and it is planned to be used also for CME purposes. Our experience matches the views of Reavie et al (2010), Steinberg et al (2011a,b), Maurer (2011) andStehouwer et al (2012) who also concluded that staining and epifluorescence microscopic observations are reliable and efficient methods to evaluate the concentration of living phytoplankton organisms.…”

“…It is not our intent to 'elect' the best indicator of viability, since each one of these methods has its own set of advantages and limitations (see 'Introduction'). For those involved in ballast management, however, assessment of viability is essential for compliance with regulatory practices (see Regulation D-2, IMO 2004) and access to live samples has become mandatory; thus the need to consider the use of vital stains in such cases (Reavie et al 2010).Actual growth is still a less disputable sign of viability. Viable diatoms have been found in ballast tanks, as demonstrated by incubation experiments with ballast waters (Subba Rao et al 1994, Rhodes et al 1998, Forbes & Hallegraeff 2002, McCarthy & Crowder 2000, Marangoni et al 2001, Burkholder et al 2007) and ballast sediments (Hallegraeff & Bolch 1992, Kelly 1993, Pertola et al 2006, although growth rate potentials had not been quantified before.…”

This research uses the concept of propagule pressure (number of individuals introduced and number of introduction attempts) to investigate human-mediated bioinvasion patterns. We quantified diatoms in the sediments of ballast tanks of commercial ships arriving on both Canadian coasts during 2007 to 2009. Diatom cell concentrations varied from non-detected to 10 5 cells g -1 wet weight (10 11 cells per tank). Although the lowest values were often found in tanks that underwent ballast water exchange, the highest concentrations (10 9 to 10 11 cells per tank) were detected in all voyage categories: transoceanic with ballast exchange (TOE), and intra-coastal with exchange (ICE) and without exchange (ICU). For the west coast, 36% of tanks carried detectable quantities of diatoms and there was no statistical difference between ship categories. For the east coast, 60% of tanks contained diatoms; ICU represented a bioinvasion pattern based on more frequent events with consistently lower cell concentrations, whereas ICE and TOE corresponded to less frequent events, though more variable in cell concentrations. Diversity reached 40 taxa per tank, including resting stages and cells that were supposedly growing vegetatively. New records may lead to introduction hypotheses that ought not to be accepted uncritically. Cell viability was tested using the vital stain fluorescein diacetate; parallel counts of protoplasm integrity and chlorophyll autofluorescence revealed that all 3 indicators gave results within the same order of magnitude. Inoculation of 0.2 to 0.5 ml of the slurry into culture media led to the growth of diatoms, even of taxa not initially detected. Within 7 d, cultured assemblages reached cell concentrations equivalent to 1.8 to 4.4 doublings of the original inoculation.

Dinoflagellates have been a frequent target of more in-depth investigation (Hallegraeff & Bolch 1992, Rigby & Hallegraeff 1994, Hamer et al. 2000, 2001, Pertola et al. 2006. This is mostly due to a valid perception of the survival advantage of cyst-forming species under the adverse conditions found in ballast tanks, as well as being a repercussion of case studies of toxin-producing species known to impact fisheries and aquaculture, whose bioinvasion histories have been charted based on paleontological records and/or molecular evidence (McMinn et al. 1997, Scholin 1998, Doblin et al....

“…The biological tests indicated that the high temperature might be required in order to ensure efficient destructing of micro-organisms (under ten microns) within short heating time. The larger organisms (phytoplankton and zoo-plankton) are almost destructed at lower temperatures [14]. In parallel, the water treatment process system was modelled using Bond Graph and 20SIM software [15].…”

This paper presents a novel green and costeffective ballast water treatment system which will utilize waste heat from propulsion machinery for the destruction of microorganisms in the ballast water in a relatively short time. The high temperature recovered from propulsion machinery combined with the rapid destruction of microorganisms will make the new system more effective than the current similar Ballast Water Management Systems. The research will involve a combination of biological laboratory experiments, numerical simulations, and full scale machinery testing. The project has a potential to lead to the development of methods and knowledge for efficient energy utilization, effective destruction of microorganisms, and reliable methods for sampling and testing of water quality. The latest results obtained demonstrate that the proposed idea works efficiently and effectively, while offering a satisfactory verification with on-site biological experiments.
