Hvaldimir's story prior Hammerfest remains completely unknown. Because he may have been without food for several weeks, we initiated the feeding program with only a few kilos/day in order for his body to adjust to food intake again. Daily food base was gradually increased to 15 - 20 kilos a day. Hvaldimir is a picky-eater and have only accepted herring so far. However, a variety of fish species should be added to his diet on the longer-term. We keep track of every amount of food given throughout the day. Based on his appetite and behavioral observations, we constantly adjust the daily food base. Keeping him slightly under-fed could trigger his instincts and hunting skills and hopefully, promote natural feeding.
