Marine Alien Species

The blue crab Callinectes sapidus is one of the 23 marine alien species reported for the Albanian coast so far (Beqiraj et al., 2012; Katsanevakis et al., 2011). The first scientific report on the presence of this species in the Albanian coast is in 2009, in Patoku Lagoon. The blue crab population in Patoku Lagoon had grown significantly by 2009 and the blue crab had started to be traded. The data collected in that year showed that this species is assessed to be established in the Patoku Lagoon (Beqiraj & Kashta, 2010). Special attention has been paid to the study of blue crab population in the following years during 2010 - 2015. The aim of this study is to evaluate the development and population trend of blue crab in the Patoku Lagoon referring to the data collected throughout years of study.

Marine Alien Species

The shallow coastline of Chios Island was surveyed for the presence of any alien marine benthic species, during August 2009. Fourteen randomly selected sites were surveyed by snorkeling during standardized one-hour transects at depths between 0 and 10 m, and the presence of all identified alien benthic species was recorded. Six alien species were identified: Asparagopsis taxiformis, Caulerpa racemosa var. cylindracea, Stypopodium schimperi, Halophila stipulacea, Percnon gibbesi, and Siganus luridus. The green alga C. racemosa var. cylindracea was found in high densities in all the surveyed sites and was characterized as invasive in the island. The brown alga S. schimperi, the crab P. gibbesi, and the fish S. luridussustain established populations in the area. For three of the recorded marine alien species (S. schimperi, P. gibbesi, and S. luridus),Chios Island seems to be the northernmost margin of their geographical range in the Aegean Sea.

Marine Alien Species

Fouling polychaetes in Tanjung Priok Port, Jakarta and their status were studied in order to update the list of marine alien species in Indonesia. Polychaetes were collected using six PVC panels that were submerged at a depth of 0.5 m over three months in Jakarta Bay. Polychaetes were identified to the lowest taxon possible based on characteristics of external morphology. The geographical distribution of identified polychaetes was then determined based on taxonomic literature in order to justify whether they were native or alien species for Indonesian waters. Twelve fouling polychaetes belonging to nine families are reported here. Of these, nine species (i.e., Chrysopetalum debilis, Eunice hirschi, Ceratonereis mirabilis, Leonnates decipiens, Polyophthalmus pictus, Eulalia (Eumida) sanguinea, Lepidonotus tenuisetosus, Hydroides elegans, and Polydora ciliata) were native species, while three other taxa (i.e., Namanereis sp., Hypsicomus sp. 1, and Hypsicomus sp. 2) were undetermined.

The European Alien Species Information Network (EASIN) was created with the aim to provide easy access to accurate information on alien species in Europe. EASIN allows the retrieval of spatial information from existing online data providers in order to produce integrated georeferenced distribution maps of alien species in Europe. In November 2012, a new data provider, the Ellenic Network on Aquatic Invasive Species (ELNAIS), joined EASIN; this has significantly increased the available georeferenced information on marine/estuarine alien species in Greek waters. Here, we use maps created by EASIN to show differences in patterns of distribution in Greece for the most abundant Phyla of marine alien species - Mollusca, Arthropoda, Chordata and Annelida. We also show that the two main pathways of introduction of marine alien species (Lessepsian migration and Shipping) are related to different patterns of species spatial distribution in Greece. Overall, the tools provided by EASIN can greatly aid scientists and policy makers in obtaining high quality information on marine alien species in Greece, especially after the association with ELNAIS.

Observations of citizen scientists have become an indispensable source in the collection of biodiversity data worldwide. In Greece, the findings of these citizen scientists, in collaboration with the Hellenic Network on Aquatic Invasive Species (ELNAIS), have resulted in compiling diverse information on marine alien species. Since 2004, the Liamis Dive Centre has recorded visual data on 12 marine alien species around Pserimos Island (Dodekanisa, Greece), thus enabling us to sequence their progression and displacement amongst other vital information. The real number of biological invasions is likely to be higher than reported here because citizen scientists do not have the scientific skills required for species identification and also due to financial constraints. Nevertheless, the high number of observers to a certain extent compensates the lack of taxonomic expertise.

Impact On Biodiversity

Marine invasive alien species are sea-based organisms that are non-native to a marine ecosystem, and which can or have spread to a degree that has an adverse impact on biodiversity and human livelihoods. In a globalized and inter-connected world, the threats posed by marine invasive alien species are here to stay. Accordingly, it often has been lamented that the threats from marine alien species are too difficult to combat effectively. In Australia, these threats are exacerbated by the country's unique characteristics such as its sheer size, as well as its geographical and historical isolation from the rest of the world. More importantly for the purposes of this article, Australia's unique constitutional framework that entrenches its national system of federalism has led to complex power-sharing arrangements between the Commonwealth, and the State and Territory governments in the management of invasive alien species, which are arguably inadequate to combat marine invasive alien species effectively. In Australia, laws have been made to manage only one vector of marine invasive species, ballast water from vessels, but not for other vectors. This article analyses how marine invasive alien species are currently managed within the Australian legal framework, and discusses what can be done to improve the status quo in order effectively to control the spread of such foreign organisms. It argues with optimism that marine invasive alien species can be effectively managed under a strong legal framework that seeks to prevent their occurrence and minimize the negative impacts of their occurrence. Such a legal framework consists of sound domestic laws and institutions, the effects of which can be enhanced by greater international cooperation.

Heterocentron subtriplinervium (Link et Otto) A. Braun et C. D. Bouche, a potential invasive alien species is reported here for the first time for Asia from the Western Ghats of India. The plant is probably introduced deliberately into gardens for ornamental purpose from where it escaped and become naturalised in the Western Ghats. This species is a potential weed, which quickly conquers areas wherever introduced displacing the indigenous flora. A detailed description, illustration, photograph and relevant notes are provided for easy identification in the field.
