What maximum weight can yellowfin tuna potentially reach according to size metrics?

Over 200 kilograms (approximately 440 pounds)

Yellowfin tuna are recognized as one of the larger members of the tuna family, possessing the biological potential to grow to substantial sizes. Records indicate that they can attain lengths approaching two meters, with a corresponding maximum recorded weight exceeding 200 kilograms, or about 440 pounds. It is important to note that while this represents the upper biological limit, the majority of fish landed in commercial operations are often significantly smaller than these maximum potentials. This rapid growth rate, although influenced by environmental factors like water temperature and food abundance, allows them to reach maturity relatively quickly, which is a factor considered when determining sustainable catch limits and calculating size-at-age metrics for fisheries management.
