Grading Fish for Quality 4. Variations in the Relation Between Trimethylamine Values and Grades for Gutted, Trawler-Caught Atlantic Cod and Haddock

The accuracy of the trimethylamine (TMA) grade probability curve, developed in 1958 by Hoogland for gutted, trawler-caught Atlantic cod and haddock has been verified by tests made on 3170 cod and haddock.It has also been shown that the relation between TMA and grade is not the same for cod as it is...

Description
Summary:The accuracy of the trimethylamine (TMA) grade probability curve, developed in 1958 by Hoogland for gutted, trawler-caught Atlantic cod and haddock has been verified by tests made on 3170 cod and haddock.It has also been shown that the relation between TMA and grade is not the same for cod as it is for haddock. For a given TMA level, haddock show greater deterioration.The relation between grade and TMA also changes with the season. For a given level of TMA, fish caught in the summer and late fall usually show more deterioration than those caught during the spring months.
