“…In addition, regardless of whether the occurrence was in an area of high human use or not, the propensity of a species to raft with, or foul, man‐made structures or debris was assessed (Question 5.4a,b). These traits are known to heighten the risk of human‐mediated introduction and such vessel and debris movements are known to have introduced marine species to areas remote from centres of anthropogenic activity (Francis et al., 1999; Willis et al., 1999; Wotton & Hewitt, 2004). Last, in Question 5.5, we consider whether the species is included in the aquarium trade and could have been released in areas of high human use (i.e.…”

Aim Despite the unprecedented rate of species redistribution during the Anthropocene, there are few monitoring programmes at the appropriate spatial and temporal scale to detect distributional change of marine species and to infer climate‐ versus human‐mediated drivers of change. Here, we present an approach that combines citizen science with expert knowledge to classify out‐of‐range occurrences for marine fishes as potential range extensions or human‐mediated dispersal events. Innovation Our stepwise approach includes decision trees, scoring and matrices to classify citizen science observations of species occurrences and to provide a measure of confidence and validation using expert knowledge. Our method draws on peer‐reviewed literature, knowledge of the species (e.g. contributing to its detectability, and potential to raft with, or foul, man‐made structures or debris) and information obtained from citizen science observations (e.g. life stage, number of individuals). Using a case study of suspected out‐of‐range marine fishes in Aotearoa New Zealand, we demonstrate our approach to defining species’ ranges, assigning confidence to these definitions and considering the species detectability to overcome the data deficiencies that currently hinder monitoring the range dynamics of these species. Our classification of citizen science observations revealed that six of ten species had out‐of‐range occurrences; one of these was classified as an extralimital vagrant, four species had potentially extended their ranges and one species occurrence was likely due to human‐mediated dispersal. Conclusion The case study of marine fishes in New Zealand validates our approach combining citizen science observations with expert knowledge to infer species range dynamics in real time. Our stepwise approach helps to identify data deficiencies important in informing scientific inferences and management actions and can be refined to suit other data sources, taxonomic groups, geographic settings or extended with new steps and existing tools.

“…In 1998, the Australian bridled goby, Arenigobius bifrenatus, was discovered in New Zealand and it is now well established in estuaries of eastern Northland and Auckland. It is thought to have been introduced with ballast water from passing ships (Willis et al 1999;Francis et al 2003). A small brackish water microdesmid, probably the Australian Parioglossus marginalis, was recorded for the first time in 2000 from saline streams entering estuaries at North Cape and Great Barrier Island.…”

Twenty-four blennies collected in east Auckland, New Zealand, were identified as the Australian oyster blenny, Omobranchus anolius using taxonomic and molecular characters. This species appears to have been introduced recently to New Zealand. Auckland oyster blennies mainly inhabited dead oyster shells in water pooled under intertidal boulders on mudflats. Specimens ranged from small juveniles to large mature males, suggesting that the species is breeding in New Zealand, or that there have been multiple incursion events. Oyster blennies may be capable of colonising estuaries throughout the northern North Island, and possibly farther south. Control or eradication of O. anolius would be facilitated by its intertidal habitat, lack of an escape response when found, and the very limited movement and natural dispersal of adults and larvae.

“…Grahamichthys radiata, F. malcolmi, and Engraulis australis) inside sea-chests is of considerable interest. The introduction of many fish species, particularly in the gobiidae and blenniidae around the world has largely been attributed to ballast water ; Springer and Gomon 1975;Al-Hassan and Miller 1987;Pollard and Hutchings 1990;Willis et al 1999;Francis et al 2003). However, very few ballast water surveys to date have actually collected fishes (e.g.…”

The Nature, Extent and Survivorship of Biofouling Organisms at Different Hull Locations on Various Vessel Types

The importance of vessel biofouling as a vector for the dispersal of non-indigenousmarine species (NIMS) is only just beginning to receive international attention. At thetime of commencing this study, there was a considerable lack of knowledge surroundingwhich vessels, hull locations, levels and types of biofouling pose the greatestbiosecurity risk. Therefore, the aim of this study was to investigate the nature, extentand survivorship of biofouling organisms on various vessel types at different hulllocations and offers a pragmatic risk assessment approach for managing this threat. The results of this thesis found that the recruitment, persistence, distribution, abundanceand species composition of biofouling on vessel hulls is influenced by many factorsincluding: 1) the presence/absence, age and type of anti-fouling coating; 2) voyageduration and route; and 3) port residency period. Therefore, higher levels of biofouling(species richness, percentage cover, and biomass), including NIMS are more likely toaccumulate and persist on vessels (and in hull locations) that: 1) lack and/or possess old,ineffective, damaged, inappropriate or unsuitable anti-fouling coatings; 2) spendprolonged periods stationary in ports; 3) travel at slow speeds (i.e. <10 knots); 4) haveshort voyage durations; and 5) remain at similar latitudes. Prevention is clearly better than a cure, hence the correct application and maintenanceof suitable anti-fouling coatings to the entire submerged hull surface of vessel hulls,including niche areas is the most cost-effective way of minimising the unwantedtranslocation of biofouling organisms and NIMS. However, the results of this thesisdemonstrate that if biofouling organisms colonise and establish on a vessel's hull,voyage speed alone is not capable of providing a reliable secondary level of defenceagainst the unwanted dispersal of NIMS. Clearly, the survivorship of biofoulingorganisms was highest amongst vessels that travelled at slow and medium speeds (e.g. <10 knots). Therefore, given that accumulation of biofouling follows a successionalprocess and NIMS are more likely to be associated with higher levels of biofouling,vessels that travel at slow and medium speeds are more likely to pose the greatest riskof translocating NIMS on a vessel by vessel scale. However, despite the observationthat faster vessels reduce the diversity, quantity and quality of sessile biofoulingorganisms in laminar flow areas of the hull, a wide range of sessile, sedentary andmobile organisms were still cable of survival in areas protected from harsh hydrodynamically forces commonly referred to as niche areas, particularly within sea-chests.
