Proposed or perceived target setting approach with a short justifi cation. A baseline could be set based on the current situation (baseline monitoring needed!) and then the approach adopted by OSPAR could be used. They suggest the following GES boundary “The average proportion of oiled birds in all winter months (November to April) should be 20% or less by 2020 and 10% or less by 2030 of the total found dead or dying in each of 15 areas of the North Sea over a period of at least 5 years” 4.7.

4.8. Status of salmon smolt production, smolt survival and number of spawning rivers 1. Working team Author: Atso Romakkaniemi on the basis of work in ICES WGBAST 2. Name of candidate indicator Status of salmon smolt production, smolt survival and number of spawning rivers 3. Unit of the candidate indicator Three parameters: smolt survival (%) smolt production (individuals) increase/decrease in number of rivers with natural spawning of salmon (% change from xxxx(2010?) situation) 4. Description of proposed indicator Salmon (Salmo salar) is a big predatory species in the Baltic Sea marine ecosystem. Its abundance is affected not only by commercial fi shing but also by the condition of the spawning rivers and the marine ecosystem. When smolts enter the sea, they must have enough suitable food items along their migration paths and they must be able to avoid predation and by-catching in order to survive over the fi rst, critical year. Many of the spawning rivers have been dammed to produce hydroelectricity, and the spawning grounds have in many rivers degraded due to increased siltation and eutrophication (forestry, agriculture). There are also former salmon rivers with few or no migration obstacles; natural reproduction could be re-established especially in these rivers. This indicator is a combination of three parameters, which can be assessed separately and then combined (all or part of them) to give a single measure of the status of salmon. survival of smolts in the sea, (can be also a separate indicator the conditions in marine ecosystem) number of smolt produced annually in a river, and number of salmon rivers (trend in the number of rivers). (The latter two refl ect the reproduction of salmon and has a linkage to the marine ecosystem) 5. Functional group or habitat type Anadromous fi sh 6. Policy relevance Descriptor 1: Criterion 1.1 – Species distribution Criterion 1.2 – Species abundance Criterion 1.5 – Habitat extent BSAP Ecological objective “Thriving communities of plants and animals” (Nature conservation) 7. Use of the indicator in previous assessments Derived from the ICES salmon assessments. Can be supplemented by the results of MS’s monitoring for Habitats Directive, which has not been included in ICES work which focuses only on original stocks. 8. Link to anthropogenic pressures Smolt survival decreases as a result of lack or mismatch of suitable food (invertebrates and prey fi sh like young herring/sprat/stickleback the abundance of which are affected by human) and commercial fi shing (by-catch). The smolt production depends on the number of spawners (affected by fi shing) and the quality of the river (damming and degradation of suitable habitats). The number of salmon rivers decreases as a result of damming and degradation of suitable habitats and increases as a result of restoration efforts (improving passage through migration obstacles, measures to improve water quality, fl ow regimes, physical quality of spawning and nursery habitats). 9. Pressure(s) that the indicator refl ect The indicator refl ects fi shing (commercial and recreational), state of the sea ecosystem (e.g., availability of food for young salmon), river connectivity, siltation (forestry, agriculture) and inputs of nutrients and organic matter (agriculture, waste waters, animal husbandry). 167
