As a guide, allow around 400g (14oz) of whole fish weight per person. A whole fish yields on average 40 – 50% of flesh, depending on the species (the remainder is guts, bones, head etc). This equates to 160 – 200g (5.5 – 6.6 oz) fish meat per person assuming a 40 – 50% flesh yield based on the weight of a whole fish.
The end value—the full cost of the can and contents—was nearly $26 billion, reflecting about 63% of total tuna end values, versus 33% for sashimi products. Although tuna remains a staple protein, canneries also produced 1.4 million metric tons of byproduct, primarily used in fish meal and pet food and estimated to be worth another $448 million.
