Kai  Mattsson


Main working experience:


My work with marine fauna has originally started when I managed to get a job, through my hobby, in the largest public aquarium in Finland, the Särkänniemi Aquarium. At that time it was the only recognized public aquarium in Finland. 

Before that I had been working in a pet shop in 1980-1981.


Meritime Consulting (2004 – present)


In 2004 I founded my own company Tmi Meritime.

Meritime Consulting is giving me a possibility to practice other interest of life which cannot be done within the framework of my commitments to my work with fauna.

The need for Meritime came from the demand of producing show & theatrical productions and acting in such productions outside of my regular work as well as a dawning interest from dog & domestic animal community for lectures on animal behaviorism from me.

Since then I have done several productions to different communities or companies; churches, theaters, dog clubs and professional animal trainers & zookeepers.

My professionalism includes:

EAZA Academy (2016 - ongoing)

             In early 2016 I got accepted to EAZA Academy as educator & instructor. The responsibilities of this position is to develop and deliver high quality animal welfare & behavior managements strategies to EAZA zoological environment animal care and via this increase the training and welfare of animals under human care within this community to it's members. 


  In 2023 I was inviter to join the EAZA Animal Welfare Working Group as on official Advisor  (EAZA AWWG Official Advisor) within the organisation.

Särkänniemi Oy, Aquarium; (1982-86 / 2015 - present) 

At the Aquarium I worked from 1982 to 1986, first as a part time worker but I soon became a full-time employee. The work at the Aquarium has been very independent and it includes taking care of tropical fresh- and marine fishes as well as fresh- and marine coldwater fishes. Planing and construction of new exhibits and operating, control and maintenance of filtering systems was also part of my work. At the Aquarium we also had two seals; a harbor seal, Phoca vitulina, and a grey seal, Halichoerus grypus, taking care of these animals was also part of my daily routine.



Särkänniemi Oy, Dolpinarium; (1985-2016)  

                      In 1985 I started my work at the Dolphinarium of the Särkänniemi Oy in Tampere, Finland. First I was assisting the care take of bottlenosed dolphins, Tursiops truncatus but soon my position was changed into fulltime employment with dolphins. After that I pretty soon got in the training of these dolphins and in 1989 my position at the Dolphinarium was changed into the Head Trainer/Curator of the facility.


My responsibilities have included:


I have also given my input in management of the Dolphinarium as a foreman of the training staff and in planning of the budget of the Dolphinarium.

In 2011 my position was upgraded into an Expert in Marine life and Animal behaviorism & a Curator & Senior trainer at the Dolphinarium.


EAAM  (membership 1987 – 2017) 

(European association for Aquatic Mammals)


European Association for Aquatic Mammals (EAAM), in which I have been a member r since late 80's. 1997-2004 I held the position of the Secretary /Treasurer of the EAAM. In 2004 I was re-elected to the board of the Association (past the terms defined in the bylaws) as a co-opted board member for the next two years. The position in the board lasted therefore altogether 8 years. This work keeps me constantly in contact with the marine mammal society. In those years I was heavily involved in the development of the association to what it is today, I also was involved with putting up the scientific program of each annual meeting of the Eaam by giving formal presentations in the meetings and organizing i.e. training workshops for the international organization.

My commitment with the Eaam is still an ongoing process. I have been involved with the association and its members in i.e Professional Cetaceans (IMM) -group as well as in 2010 founded accreditation group.

I’ve been involved in the association by giving formal presentations (~lectures) in its annual meetings, by participating its working group meeting and by being involved in organizing European regional meeting of the association.

In 2011 I’ve started to work with the organization again as a member of the association’s training committee for approximately 5 years time.

In 2000 The Ministry of Environment chose me to be the official representative of Finland in the Advisory Committee of the ASCOBANS. Basically the work is related to porpoises, Phocoena phocoena, the only cetacean rarely found from Finnish coastal areas. My duties include participation of the Ascobans Advisory Committee meetings and to the Meetings of the Parties. By doing this I am in close relationship with Finnish ministry of environment to see that all obligations of the agreement shall be implemented in Finland.

In 2001 I was asked by the Finnish government to participate as an expert in the development of organizing a network in Finland within the Agreement of the Conservation of Small Cetacean in the Baltic, North East Atlantic, Irish and North Seas (ASCOBANS). This work is done in co-operation with Finnish Ministry of Environment. With the ministry and some other co-organizations we founded Finland's "Porpose - working group" in order to spread knowledge of this species and to collect all data of sighting of porpoises in the Finish sea areas.

In 2004 a formal working group was established from the basis of the Porpoise group Finland by the Ministry of Environment to implement EU regulations and Ascobans references for Recovery Plan of Baltic Harbour porpoise. I was chosen to this working group as a permanent expert on marine mammals. The outcome of the working group was delivered to the minister of environment in 2006 - An updated to this statement was done and delivered in august 2016.
