Abstract The refractive index of cod muscle was measured during stowage of the whole fish in ice and during cold‐storage of fillets at −14° and −29°. These treatments caused, respectively, a decrease and an increase in refractive index, the increase at −14° being faster than that at −29°. The possibility of using refractive index to measure the deterioration of fish is discussed.
