Sci. The yellowfin tuna reaches a maximum weight of about 180 kg (397 pounds), and the albacore grows to about 36 kg (79 pounds). [26], However, since bluefins require so much food per unit of weight gained - up to 10 times that of salmon - if bluefins were to be farmed at the same scale as 21st-century salmon farming, many of their prey species might become depleted if farmed bluefin were fed the same diet as their wild counterparts. One spawning ground exists in the western Mediterranean, particularly in the area of the Balearic Islands. This is why, in 2017, WWF criticized ICCAT’s decision to set the highest quota increase of bluefin catches — up to 36,000 tonnes — by 2020.
