Gokoglu et al. (2004) reported that the Mg content of rainbow
trout significantly decreased after frying, grilling, baking and boiling,
but there was no significant decrease in the microwave cooked
samples. According to Ersoy and Özeren (2009) and Rosa et al.
(2007) the Mg content of cooked African catfish increased significantly
during cooking. Our findings were opposite to these results.
