Habitat type
Estuary. River mouth, transition zone between riverine and marine environments, subject to influences from both.
Lagoon. Shallow, enclosed water body separated from the sea by barrier islands, narrow spit or reefs.
Offshore. Areas located at least 50 nautical miles from the shore.
Open coast. A coast not sheltered from the sea.
Strait/Sound. Channels between the mainland and an island or between two islands which are open at both ends to the open coast (it does not refer to similar features or narrows within marine inlets).

Pathway / Vector
Pathway
A pathway is the route a NIS takes to enter or spread through a non-native ecosystem e.g. vessels. Each pathway may have a number of vectors.
VectorA vector is a transfer mechanism and is the physical means by which species are transported from one geographic region to another. More than one vector within a pathway may be involved in a transfer of species.
Pathways and vectors included:| Pathway | Vector |
| Aquarium trade | Intentional organism release Transported water Waste discharge |
| Culture activities | Aquaculture equipment Associated water & packaging material Intercontinental stock movement Regional stock movement Unintentional release & escapees |
| Leisure activities | Angling catch Cultural releases Live bait Live souvenirs Sport equipment Stocking for angling Waste discharge |
| Live food trade | Intentional organism release Transported water Waste discharge |
| Management | Biological habitat management Construction equipment Construction materials Release for biological control |
| Natural spread from neighboring countries | Other natural vectors Water currents |
| Other canals | Canal de Midi (linking the Bay of Biscay with the Mediterranean Sea) Kiel Canal (linking the North Sea with the Baltic) Northern waterway (linking the Baltic with the Ponto-Caspian region through Volga river canal system) Rhone waterway (linking the North Sea with the Mediterranean) Southern waterway (linking the North Sea with the Black Sea through Danube river canal system) Central waterway (linking the Baltic Sea with the Black Sea through the Dnieper river canal system) Other waterways Irrigation canals |
| Research and education | Gear movement Intentional releases Unintentional release & escapees Waste discharge |
| Suez Canal | |
| Vessels | Anchor and anchor chain Ballast tank sediments Ballast water Ship’s hull Sea chest Others |
| Wild fisheries | Discard of by-catch Fishing gear Live bait release Live packaging material Processed live material Stock movements Transported water |
Pathway / Vector – Levels of certainty:
| Level | Criteria | Examples |
| Direct evidence | The species was actually found associated with the specific vector(s) of a pathway at the time of introduction to a particular locality within a country/country region. | Documented evidence of an introduction: release to the wild for stocking or biological control; escape/release of live food; import of cultured species and documented findings of their associate organisms, parasites and diseases on transmission; appearance of organisms by hull fouling, ballast water discharge sampling or other ship vectors documented upon an arrival with appropriate scientific methods. |
| Very likely | The species appears for the first time in a locality where a single pathway/vector(s) is known to operate and where there is no other explanation that can be argued for its presence except by this likely pathway/vector(s). | A highly localized distribution of a species in an area adjacent to an isolated port or other locality where the only pathway is vessels and its vector(s) (ballast water, hull fouling, etc). This often involves geographically discontinuous distributions. It may be a continuous spread as in case of introduction by canals or by natural means. The conclusion is deduced from the analysis of the invasion event and species distribution patterns. |
| Possible | The species cannot be convincingly ascribed to a single pathway, but is known to be introduced by this pathway(s) elsewhere. | There may be more than one pathway involved in the introduction within a country/country region. Arrival of a species known to have taken place elsewhere by the same pathway(s) which operates in an area. A conclusion is made by expert judgment based on pathways currently or historically present. |
| Unknown | Invasion of a given alien species cannot be clearly explained. | Where no rational explanation for the appearance of a species in a given country/region. |

Source region
The area the species was introduced from to the recipient country/country region. Depending on the information availability may be ascribed to a particular locality (e.g. port), a country, a LME or a larger Ocean region.
CAUTION: in many cases the source area will be not the same as the area of native origin which is defined in the SPECIES block of the database.
Species status
Non-indigenous species. Non-indigenous species (synonyms: alien, exotic, non-native, allochthonous, introduced) are species, subspecies or lower taxa (such as a variety, form) introduced outside of their natural range (past or present) and outside of their natural dispersal potential. This includes any propagule of a NIS, such as a gamete, seed or resting spore, a gravid female or a pair of individuals of different sexes (in sexual reproduction), or a vegetative reproductive organ and section of tissue (in asexual reproduction), which might survive, reproduce and subsequently form a population. It also includes hybrids between an alien species and an indigenous species, fertile polyploid organisms and artificially hybridized species irrespective of their natural range or dispersal potential.
Cryptogenic. Cryptogenic species are such species which cannot be reliably demonstrated as being either introduced or native. In some cases the true origin of a species remains obscure because of either insufficient taxonomic knowledge or due to a lack of records from the time they became introduced, or for other reasons.
Temperature range
Indicate min. and max. annual temperature range in the area where a species is known to maintain an established (reproducing) population.
Wave exposure
Exposed. Open coastline facing prevailing wind and receiving both wind-driven waves and swell.
Semi exposed. Generally open coasts facing away from prevailing winds or sheltered by offshore reefs/structures.
Sheltered. Coasts with a restricted fetch (<20 km) and lacking persistent swell.
Zonation
Ecological zone(s) occupied by a species throughout its life cycle.
Benthic - Bathyal. Synonym: continental slope. The seafloor between the edge of the continental shelf and abyssal plain (200-4000 m).
Benthic - Littoral. Synonym: intertidal. The shore between the high and low water marks.
Benthic - Sublittoral beyond photic zone. Synonym: lower circalittoral. The lower part of the continental shelf, where photosynthesis cannot take place.
Benthic - Sublittoral within photic zone. Synonyms: subtidal, infralittoral. The shallow part of sublittoral where photosynthesis can occur.
Benthic - Supralittoral. Synonyms: splash zone, spray zone, supratidal zone. The area above the spring high tide line, subject spray or splash.
Pelagic - Littoral. Water mass within littoral zone.
Pelagic - Neritic. Water mass above the continental shelf.
Pelagic - Offshore. Synonym: oceanic. Water mass beyond the continental shelf.
