The causes of soft flesh in giant grenadier (Albatrossia pectoralis) were investigated. The softness of giant grenadier flesh was related to its high moisture and low protein content, averaging 91.4% and 6.8%, respectively, and its muscle structure. The ratio of water to protein (13.4) was almost three times higher than for Dover sole (5.9) and Alaska pollock (4.7). Compared to Alaska pollock, giant grenadier muscle had large myotomes in loose bundles, characteristic of soft fleshed fish. Protease activity was low and as in Alaska pollock not considered a factor in soft flesh.
