“…The findings of the present study agree with the recent work of Davidson et al (2008), who assessed the efficacy of a submersible cleaning and maintenance platform (SCAMP) on obsolete vessels that had developed extensive fouling (up to 30 cm thick). Their study found that while the SCAMP was capable of significantly reducing fouling cover and diversity, posttreatment investigations undertaken 3 days after defouling revealed a 'substantial and diverse' fouling community across the entire vessel.…”

“…It is worthwhile highlighting that the fouling extent (cover, richness and biomass) that accumulated on experimental plates deployed for 3 months represents the upper range of that expected on commercial vessels in frequent use (eg Coutts and Taylor 2004;Davidson et al 2009). Plates deployed for 6-12 months had fouling assemblages comparable to that described for vessels that had been idle for an extensive period (eg Davidson et al 2008). As such, the efficacy of the brush systems tested, in terms of biofouling removal, is likely to be an underestimate of their performance on a 'typical' vessel.…”

The present study tested two diver-operated rotating brush systems, coupled with suction and collection capabilities, to determine their efficacy in the management of vessel biofouling. Both rotating brush systems proved effective (> 80%) in removing low-to-moderate levels of fouling from flat and curved experimental surfaces (Perspex plates). However, performance was generally poorer at removing more advanced levels of fouling. In particular, mature calcareous organisms were relatively resistant to the rotating brushes, with a high proportion (up to 50%) remaining on plates following treatment. On average, > 95% of defouled material was collected and retained by both systems. The amount of lost material generally increased when treating curved plates with increasing biomass, whereas the material lost from flat plates was typically less and remained relatively constant throughout the trials. The majority (> 80%) of fouling not captured by the systems was crushed by the brushes (ie non-viable). However, a diverse range of viable organisms (eg barnacles and hydroids) was lost to the environment during the defouling trials. When defouling a vessel, unintentional detachment of fouling organisms is likely to be high through physical disturbance by divers operating the devices and by associated equipment (eg hoses). Furthermore, residual biosecurity risks are also likely to remain due to diver error, persistent fouling remaining on treated surfaces and the inaccessibility of niche areas to the brush systems. To address these limitations, further research into alternative treatment methods is required.

“…These include in-water cleaning, in-water treatment (e.g. heat treatment to neutralize biofouling organisms), encapsulation (with possible chemical treatment), temporary repositioning to freshwater sites, haul-out for power washing and air drying, and biological surveys for unwanted NIS or pest species (Wotton et al 2004;Coutts and Forrest 2007;Davidson et al 2008b;Atalah et al 2016). Few jurisdictions have policy frameworks to manage invasion risks from this vector, although New Zealand imposes biofouling thresholds or requires documentation of best-practice husbandry and maintenance for all vessels and SMS entering coastal waters (New Zealand Government 2014).…”

Biotic exchange from movement of ‘static’ maritime structures

Coastal infrastructure provides extensive habitat for marine nonindigenous species (''NIS''), especially biofouling species. Ecosystem transplants can arise when static maritime structures (''SMS'') are relocated under slow towing speeds following long periods of biofouling accumulation. Translocations of SMS occur more often than acknowledged and represent a high-risk vector of marine NIS that is largely overlooked and unregulated. We compiled geolocations and movement patterns for oil platforms, derelict/obsolete vessels, barges, dry docks, floating lodges, homes and docks, aquaculture gear and buoys for the NE Pacific coast. We related these data to NIS richness within the region and to global examples of SMS movement. Our review and synthesis of SMS, paired with biofouling surveys before and after dock towing events, reveal the growing NIS vector opportunities resulting from sprawling coastal infrastructure. As coastal development continues apace in the Anthropocene, this emerging management challenge will require strong frameworks and workable solutions for a global issue that currently lacks incentives to prevent species transfers and invasions.

“…In a study of non-chemical control methods, Davidson et al (2008) monitored the efficacy of in-water scrubbing by hand and by a mechanized machine on the fouling organisms on a ship's hull, including dark falsemussels and hooked mussels. Scrubbing reduced organism cover significantly but not completely.…”

The invasive dark falsemussel Mytilopsis leucophaeata (Bivalvia: Dreissenidae): a literature review

This paper reviews literature from the Americas and Europe on the dark falsemussel Mytilopsis leucophaeata (Conrad in J Acad Nat Sci Phila 6(2):256-268, 1831), including data collected in its native habitat in the Americas that appear as incidental information in published reports. Mytilopsis leucophaeata is a poorly studied dreissenid bivalve that is native to mainly oligohaline-mesohaline regions of estuaries in North America. In its native habitat, it usually occurs in very low numbers and has rarely been mentioned in field survey reports. However, occasionally in its native habitat and often in habitats where it has been introduced (as in Europe and Brazil), it may undergo population irruptions for no clear reason. This review describes habitat characteristics, environmental tolerances, and biological and ecological attributes of the species. The assembled information reveals the species to be euryhaline and eurythermal, with an unexplained ability to persist in its native estuaries even though it is relatively short-lived and usually uncommon.
