Criteria D1C1 is not used for determining GES because there is not enough reliable data about mortality rate per bird, seal and fish species from inci­dental by-catch. Criteria not applicable for pelagic habitats.

There is not enough reliable data on birds and seals to determine GES. Criteria D1C3 is secondary criteria for birds and seals, therefore determining GES is not mandatory. Not applicable for pelagic habitats.

Not mandatory for birds and not applicable for pelagic habitats. Four fish species covered by Annexes II (Cobitis taenia; Cottus gobio; Lampetra fluviatilis) and V (Coregonus lavaretus) of Directive 92/43/EEC are permanently inhabiting Estonian marine waters. For Cobitis taenia and Cottus gobio the data is fragmented mainly due to lack of monitoring of these species, therefore developing threshold values and assessing GES was not possible. Lampetra fluviatilis and Coregonus lavaretus are very mobile species. The distributional range is not related to any specific habitat type and therefore assessing the habitat extent and condition is not applicable for Lampetra fluviatilis and Coregonus lavaretus. Under the criteria, only the extent and condition of migratory fish spawning areas can be assessed via assessing Salmo salar spawning sites.
