Back in the summer, on a particularly sunny day, I boarded a ferry to visit a friend on Nantucket Island. Upon arrival, while sifting through the many vacationers to find my friend, I crossed paths with a bluefin tuna. It was perched on the nearest dock and weighed 750 pounds. A crowd of local fishermen circled the fish, taking photos, slicing into the belly, and even sneaking small bites.
Chunk (or chunk light) tuna will be cut into smaller pieces, appearing as flakes or shreds. When you crack open a can of solid tuna, you'll instead find larger and intact pieces of fish. Given the different sizes of these pieces, you can also expect different textures. For example, chunk tuna will provide a softer and flakier bite, whereas solid options will be firmer and meatier.
