GES description |
GES is achieved if subpopulation of spring spawning baltic herring (Clupea harengus membras) and Baltic sprat (Sprattus sprattus balticus) actual fishing mortality (F) is lower than the fishing mortality level that would provide maximum sustainable yield (Fmsy). GES = F |
GES is achieved if spawning stock biomass (SSB) of subpopulation of spring spawning Baltic herring (Clupea harengus membras) and Baltic sprat (Sprattus sprattus balticus) is equal or higher than minimum value of spawning stock biomass (Btrigger) which would ensure fishing mortality level that would provide maximum sustainable yield (Fmsy). GES = SSB ≥ Btrigger.
In case of flounder (Platichthys flesus), perch (Perca fluviatilis) and pikeperch (Sander lucioperca), GES is determined via abundance index of sexually mature flounder, perch and female pikeperch in monitoring catches. GES is achieve if index value is >0,6.
In case of Baltic salmon (Salmo salar), GES is determined via indicator smolt production of Baltic salmon relative to the level of natural smolt production capacity on a riverby river basis. GES is achieved if the smolt production of Baltic salmon is 75% of the potential Smolt Production Capacity of the riverby river basin. |
GES for flounder (Platichthys flesus) is determined via indicator 95 % percentile of the length distribution of flounder (Platichthys flesus) in monitoring catches. GES is achieved if the indicator value is >0,6.
GES for perch (Perca fluviatilis) is determined via abundance index of large (TL>250 mm) perch (Perca fluviatilis) in monitoring catches. GES is achieved if the indicator value is >0,6.
GES for pikeperch (Sander lucioperca) is determined via indicator 95 % percentile of the length distribution of pikeperch (Sander lucioperca) in monitoring catches. GES is achieved if the indicator value is >0,6. |

Justification for non-use of criterion |
Baltic salmon: data about Baltic salmon (Salmo salar) in Estonian marine area does not enable to assess directly fishing mortality rate under criteria D3C1. However it can be assumed that if the spawning stock status is good enough to ensure the smolt production of Baltic salmon in 75% of the potential Smolt Production Capacity of the riverby river basin, then the fishing mortality can not be higher than the fishing mortality level that would provide maximum sustainable yield (Fmsy). |
GES has not been determined for subpopulation of spring spawning Baltic herring (Clupea harengus membras) and Baltic sprat (Sprattus sprattus balticus) due to 3 reasons: 1) those two species have short lifespan due to which population age and size distribution is not of primary importance; 2) assessing the population of the two species using virtual population assessment methods, the age and size data has been added to the virtual population modelling and 3) for assessing the population age and size distribution, there is no regionally agreed threshold value.
Baltic salmon (Salmo salar): current datasets does not enable to determine GES for Baltic salmon due to short data series. There is only three year data (2015-2017) available about the sizes of spawning Baltic salmon which is not enough to develop reliable indicator for assessing Baltic salmon population age and size distribution. |
