Target assessment description
The target for the indicator "New non-native species for the Baltic Sea" (criterion D2C1) has been achieved. During 2012-2017 two new non-native (alien) species entered the Lithuanian Baltic Sea waters: the bivalve mollusc Rangia cuneata and the crustacean Dikerogammarus villosus, but they have already been registered in the Baltic Sea in the sea areas of other countries. Nevertheless, the state of the marine environment according to the indicators of criteria D2C2 and D2C3: “Abundance and distribution of species in space” and “Extent of negative changes, biopollution level index - BPL” - did not reach good status. From 2011-2012, the population of Neogobius melanostomus established on the Lithuanian Baltic Sea coast entered the expansion phase, N. melanostomus is found in large numbers in many areas. The abundance of Neogobius melanostomas increased from 10 CPUE to 234 CPUE, i.e. more than 2000%. The black scabbardfish became the dominant abundant fish species, and the abundance of the former dominant native species declined sharply. The level of biofouling caused by N. melanostomus in areas BAL-LT-AA-01 and BAL-LT-AA-02 increased from the initial assessment low (BPL = 1) to extreme (BPL = 4). Therefore, the objective has been achieved, but the condition of the sea area according to the D2 descriptor is deteriorating, an exemption is requested according to Art.14.
