GES description |
Non-indigenous (invasive) species introduced into the environment as a result of human activities (anthropogenic influence) have not caused significant changes in the ecosystem. |
The abundance and distribution of non-indigenous (invasive) species entered by anthropogenic activity in the Croatian Adriatic waters is not at high level. GES is reached. |
The trend of incidence of NIS (IAS) entered by anthropogenic activity is increasing. GES is not reached. |
Due to the lack of data on the impact of non-indigenous (invasive) species on the ecosystem, it is not possible to assess the good environmental status. |
Due to the lack of data that would allow such an assessment, ratios between the abundance of native and NIS species are not known. However, in the framework of the existing data on the distribution of NIS in Croatian waters (Caulerpa racemosa, Womersleyella setacea), it can be assumed that in some areas there are indications of reduced biodiversity. |
Currently, impacts are not assessed directly. The biopollution index (Olenin et al., 2007) assesses the magnitude of bioinvasion impacts and its applicability needs evaluation. Therefore, we believe that the determination of good environmental status in relation to the impact of NIS, based on currently available data, at this point would be premature. |

Assessment method |
Methodology of the field work is based on visual census, photo documentation and collection of samples. Those activities have to be done by SCUBA diving, snorkeling or observation and collection from shore. For each location a different methodology is applied and it is always site-specific. Only for the purpose of harbors, a modify CRIMP protocol is used as a standard methodology for NIS assessment. Mobile epifauna, such as crabs, fish and shrimps should be sampled at each site using traps. Trammel net should be used to sample near-shore fishes. Seven 32 m long single nets (height 1.8 m, 28 mm mesh) joined together (224 m) are used on different types of bottom. Data collection also has to be done using citizen science principle involving public in observation network. It has to be made by sharing information on NIS through different media (most popular magazines, facebook, etc). |
