The third sub-programme will provide information on the distribution and abundance of the porpoise.
The programme provides data for descriptors 1 (criteria D1C1, D1C2 and D1C3), 4 (criteria D4C1, D4C2 and D4C3) and 8 (criteria D8C2). Information on the death of seals in fishing gear is also provided.

Programme description |
Monitoring of the population dynamics, natural and actual range and status of grey seal and ringed seal. Abundance monitoring is conducted from aircraft. Seal bycatch data is collected from fishermen, which describes human pressure on seal mortality. |
Monitoring of the population dynamics, natural and actual range and status of grey seal and ringed seal. Abundance monitoring is conducted from aircraft. Seal bycatch data is collected from fishermen, which describes human pressure on seal mortality. |
Each year, the sub-programme monitors the age and sex structure, reproductive efficiency and health status of seal populations, in particular the nutritional status. Samples are collected from seals caught/recovered by-catches by hunters and fishermen. Most of the samples come from hunted seals.

|
The sub-programme monitors the presence of porpoise in Finnish territorial waters by acoustic methods in the North Baltic and Ã
land Seas, where the species is regularly present. This information is complemented by public perceptions. In addition, data are collected on the number of porpoises killed in traps, which illustrates the human impact on porpoise mortality. The objective is to collect data on the Baltic porpoise population as part of international cooperation to preserve the harbour porpoise population classified as critically endangered in the main basin.

HELCOM:n asiantuntijaryhmä kehittää parhaillaan koko Itämeren kattavaa indikaattoria ”Abundance and distribution of harbour porpoises”. Tämän indikaattorin kynnysarvoja hyvälle tilalle tai mahdollisia alaindikaattoreita ei ole vielä määritelty, mutta kansalliset merenhoidon hyvän tilan määritelmät ovat:
• Pyöriäisen levinneisyysalueen reunat ulottuvat Suomen merialueille, pl. Perämeri, ja se havaitaan vuosittain kullakin merialueella (Suomenlahti, Pohjois-Itämeri, Selkämeri, Merenkurkku, Saaristomeri ja Ahvenanmeri).
• Pyöriäisen populaation tulisi kasvaa Itämeren pääaltaalla kohti elinvoimaista populaatiokokoa. |

The calculation methods should remain constant. When factors affecting the visibility of seals can be taken into account, the overall population estimates are also reliable. The same methodology is used in all Baltic Sea countries. The stock assessment of the regime is only reliable at the level of the Baltic Sea as a whole. With a more detailed structure, the stock distribution cannot be carried out outside the hair exchange period. Elephant stock assessments and sub-stock allocation are reliable. There are four distinct core areas of occurrence in the Baltic Sea: The Bothnian Sea, the Archipelago Sea, the North Sea of the Gulf of Finland and the Gulf of Riga.

The acoustic monitoring method used has been proven to be reliable and widely used in other parts of the world and the results are comparable to those carried out in other Baltic Sea countries. All acoustic observations are manually verified. Visual elements shall be interviewed and the reliability of the findings assessed by the expert group before entering them into the databases.

Data management |
Raw data is only available to researchers.
The seal material shall be available in the Lukeâs comparison database and public viewable and open clustered number data, with an accuracy of 50 km of ICES rectangles. For each rectangle, a multiple of the calculation times the maximum data of the detected halls shall be reported. For elephants (Fael Sea), the original data is in Swedish.
