If you are interested in the hormone levels of the fish, it is important to know whether or not it is grown in fish farms or caught in the wild. Fish farms are more likely to have GMO fish (genetically modified organism). On the other hand though, wild fish are more likely to have large amounts of Mercury in their system (mercury passes through the food chain increasing in amount the higher up the creature is as mercury stays in the system). Mercury will impair neurological functions and the most susceptible are the young (esp. fetuses).
