GES description |
Kaikkien kaupallisesti hyödynnettävien kalojen sekä äyriäisten ja nilviäisten populaatiot ovat turvallisten biologisten rajojen sisällä siten, että populaation ikä- ja kokojakauma kuvastaa kannan olevan hyvässä kunnossa
|
Kalastusteho ei minkään kaupallisen lajin kohdalla ylitä tasoa, jossa saavutetaan kestävä enimmäistuotto (MSY).
|
Herring, sprat and cod: Indicator on the fishing mortality rate (F)
|
Their share of all stocks subject to a regular stock assessment, for which fisheries are fished, based on the MSY principle.
|
Kalakantojen luontainen lisääntymiskapasiteetti on kunnossa ja kutevia emokaloja on riittävästi turvaamaan kannan normaali lisääntyminen. Tarjolla olevien lisääntymisalueiden määrä on riittävä turvaamaan vaelluskalakantojen monimuotoisuus ja säilyminen ja kannat kestävät pyynnin ilman istutuksia.
|
Salmon: Current implementation of the migration buoy production as a proportion of existing nursery potential
|
Spawning stock size for herring and sprat segments
|
Kalakantojen rakenteessa ei ole merkittäviä poikkeamia tai muutostrendejä, jotka olisivat seurausta voimakkaasta, erityisesti pieniin tai suuriin yksilöihin kohdistuvasta kalastuspaineesta ja voisivat heikentää kantojen tuottoa. Kalat pääsevät pääsääntöisesti kutemaan ainakin kerran ennen kuin niihin kohdistuu voimakas kalastus.
|
The size distribution and the average length of the spawning rivers in the Bothnian Sea. At an early stage, the aim is to get the trends stopped
|
The degree of maturity of litter, whitefish and perch and the proportion of mature fish (Reproductive capacity of fish populations)
