Fish species from different water habitats
Owing to the low saline content of the Kotka coastal area, fish species usually
found in lakes and rivers also thrive in Maretarium.
The aquarium contains over half a million litres of water, 10 % of which is
changed over a 7-day period. The water is taken from a depth of five metres
in the Baltic Sea and filtered through a quartz sand filter. UV filtering helps
to remove additional particles and muddiness from water.
The aquarium contains a Lapland fell brook with its grayling, riverine habitat
with river lamprey, small lakes from Central Finland with their roach and rudd,
Lake Saimaa with her pikeperch and whitefish and the Baltic Sea with her sculpin
In all, Maretarium is the home of over 50 fish species - including rare ones
- of Finland's water habitats.
Research and education
Maretarium also houses a nature school and facilities for researchers. Two
researchers from the Finnish Game and Fisheries Research Institute and four
from the University of Helsinki are about to start work in Maretarium.
"Our focus is primarily on sea trout, salmon, Baltic herring, pikeperch,
sprat and whitefish. Despite the increasing recruitment, the Baltic salmon catch
has dramatically declined. The aim is to establish an extensive, versatile,
international and functional research community in Kotka, which would also be
able to serve the neighbouring areas more widely. Our aim is to develop the
co-operation in the fishery sector between local communities, Estonia and Russia,"
said Kare Turtiainen, Director General from the Finnish Game and Fisheries Research
Maretarium's nature school provides lessons for day care centres, comprehensive
schools, upper secondary schools and corporate guests. The special themes include
the river Kymijoki and the Baltic Sea. The education packages are tailored to
cater to the needs of different groups. The theme of the special exhibition
in 2002 was the Eastern Gulf of Finland National Park, celebrating its 20th
anniversary this year.
The Finnish government approved
the protection programme
In the opening of the Maretarium, Prime Minister Paavo Lipponen informed the
audience that the government had just recently approved an extensive Baltic
Sea Protection Programme. The World Wide Fund for Nature acknowledged work promoting
the protection of the Baltic Sea by giving the government a "Gift to Earth"
"Finnish experts have familiarised themselves with the environmental impact
of the oil harbour in Primorsky. Furthermore, Russia has confirmed its participation
in the Northern Dimension Environmental Partnership, including Finland, Sweden,
the European Commission and international financing institutes. The construction
of a sewage treatment plant in St. Petersburg is the most urgent project affecting
the state of the Baltic Sea presently," continued Lipponen.
Lipponen also mentioned that he was going to meet Prime Minister Kasyanov next
month at the Baltic Sea States Summit in St. Petersburg, where environmental
projects will receive priority in the discussions.
Information on other maritime attractions and fishing permits for the nearby
waters are available at the information desk by the entrance. Cafe Ariela provides
an opportunity to rest and admire the seascape over the Gulf of Finland.
Maretarium is open daily 10 am - 6 pm.
