Hamachi kama is the collar of a yellowtail fish and is common in sushi. These fish are farmed in open-net pens, and the Monterey Bay Aquarium warns that hamachi kama might have a negative impact on the environment due to their high feed requirements and potential for spreading parasites. Despite these worries, hamachi kama is a healthy choice at Japanese restaurants because of its nutritional value.
