White perch Morone americana Hybrid striped Morone saxtalis x Morone bass chrysops Icefish The “cod icefish” family is a group of large, sedentary plankton-eaters that live in the cold deep waters off Antarctica The best known of them is the fatty “Chilean sea bass,” an inaccurate but more palatable commercial name for the Patagonian toothfish (Dissostichus eleginoides), which can reach 150 lb/70 kg Its fat is located in a layer under the skin, in the chambered bones, and dispersed among the muscle fibers: toothfish flesh can be nearly 15% fat It wasn’t until the mid-1980s that cooks came to know and appreciate this lusciously rich, large-flaked fish, which is unusually tolerant of overcooking Like the orange roughy and other deepwater creatures, the toothfish is slow to reproduce, and there are already signs that its numbers have been dangerously depleted by overfishing Tunas and Mackerel Who would know from looking at a cheap can of tuna that it was made from one of the most remarkable fish on earth? The tunas are large predators of the open ocean, reaching 1,500 lb/680 kg and swimming constantly at speeds up to 40 miles/70 km per hour Even their fast-twitch muscle fibers, which are normally white and bland, contribute to the nonstop cruising, and have a high capacity for using oxygen, a high content of oxygen-storing myoglobin pigment, and active enzymes for generating energy from both fat and protein This is why tuna flesh can look as dark red as beef, and has a similarly rich, savory flavor The meaty aroma of cooked and canned tuna comes in part from a reaction between the ... fast-twitch muscle fibers, which are normally white and bland, contribute to the nonstop cruising, and have a high capacity for using oxygen, a high content of oxygen-storing myoglobin pigment, and active enzymes for generating energy from both fat and protein... of tuna that it was made from one of the most remarkable fish on earth?
