Fish got sick from bad food
Thyroid neoplasia associated with nutritional deficiency in cultured jade perch in Hong Kong

Surprising Findings
Thyroid cancer was found in 3,000 farmed fish linked directly to diet.
Malignant thyroid neoplasia is rarely reported in teleost fish. Finding it at such scale in farmed fish due to nutritional deficiency is highly unusual and suggests a preventable cause.
Practical Takeaways
Use commercially formulated feed with balanced nutrients in aquaculture to prevent thyroid disease in farmed fish.

Not getting enough iodine might cause abnormal cell growth in important glands and organs like the thyroid, breasts, uterus, and prostate.
Farmed jade perch are getting tumors in their thyroid because their food is missing important nutrients like iodine and vitamin C — scientists found this by checking the fish tissues and their feed.
Fish raised on farms might get thyroid tumors over time if their food lacks important nutrients, and we've seen signs of this in jade perch that were fed a poor diet.
If jade perch on fish farms are fed homemade food that's really low in iodine and vitamin C, they might end up with thyroid problems — and this was seen in real farm conditions by checking the food and the fish's tissues.
