Reduced reproduction capacity has been recorded in several fish species in the Baltic sea during recent years.This concerns for example Atlantic Salmon (M-74 syndrome) and northern pike.In several projects we are trying to elicidate and evaluate factors which can influence on the reproductive capacity of fish.The attention is mainly focused on diet factors (thiamin/thiaminase, C-vitamin etc.) and on ecological factors which can have influence on the survival of fish fry in our coastal waters.
