💡 Everyday Comparisons for Size, Mass & Speed
- 💡 The U.S. NOAA notes that it is especially prized for sushi and sashimi because of its high fat content.
- 💡 Korea's Ministry of Oceans and Fisheries (2018) introduced the shipment of farmed Pacific bluefin tuna in Korea that were placed in sea cages as juveniles weighing about 3 kg and raised to 30 kg in 22 months.
- 💡 A maximum length of 3 m is about two-thirds (2/3) the length of a passenger car (about 4.5 m) (Comparison).
Reference standards: coach bus ~12 m, mid-size car ~4.9 m, compact car ~1 t, basketball hoop 3.05 m, credit card 8.56 cm.

📖 1. Overview
The Pacific bluefin tuna is a large tuna that migrates long distances across the North Pacific, while some individuals spend their entire lives in the western Pacific.
🦴 2. Anatomy & Morphology
It is reported to reach a maximum length of 3 m and a weight of up to 450 kg, while a typical adult is about 1.5 m long and weighs around 60 kg.
🔍 3. Ecology & Behavior
It feeds mainly on squid and fish such as sardines, anchovies, sauries, herring, and mackerel, and a trans-Pacific migration can take 55 days.
🇰🇷 4. Connection to Korea
Korea's Ministry of Oceans and Fisheries stated that about 600 tons of the Pacific bluefin tuna quota caught in domestic coastal and offshore waters are linked to aquaculture, and introduced a case in which juvenile Pacific bluefin tuna were raised in sea cages to 30 kg in 22 months.
