New indicator on ringed seals
|New indicator has been established on the number of ringed seals in the Bay of Bothnia alongside the indicator on Baltic gray seals. The indicator has been developed with Finnish Game and Fisheries Research Institute.
The number of observed ringed seals in the Bay of Bothnia has had an increasing trend since 1988. In the 2000s the population has grown by 2000 individuals, being more than 6 200 in 2012. The population is nevertheless growing only in the Bay of Bothnia. In other areas in the Baltic Sea, Gulf of Finland, Southwestern Archipelago and the Gulf of Riga, the population has not increased.
The main threats for ringed seals in the Baltic Sea are warming winters and increasing ship traffic as well as getting caught in fish nets and drowning.
