We toured their hatchery and swam in the deep water pens in the Sea of Cortez with adult Baja Kanpachi. We had heard that fish farms were crowded, unhealthy, and that the fish were living in their own refuse and being treated with antibiotics and hormones to ward off disease, parasites, and bacteria. We also know that the large deep-water fish that we love to eat, like tuna, contain dangerous levels of mercury and can also contain plastics, whereas fish such as these Baja Kanpachi can be raised with little to none. We began to understand why this special new method of farming deserves attention.
