ABSTRACT

The enzyme makeup of aquatic organisms is directly related to growth and ulti­ mately to the tissue composition, nutritive value, shelflife, and edible character­ istics of seafood. Intraspecific factors (e.g., biological age, diet, water quality and habitat temperature, etc.) are known to influence the composition, post­ mortem durability, and edible characteristics of seafood (1,2). The primary im­ portance of enzymes rather than microorganisms to the loss of prime quality in seafood has been reviewed elsewhere (3). The seafood technologist is thus con­ cerned with the influence of adaptation and intraspecific factors on the compara­ tive biochemistry of fish tissues, notably muscle tissues.
