ABSTRACT

Two tables are presented that survey the presence or absence of thiaminase in freshwater and marine fish and shellfish.

INTRODUCTION vitally important to feeders, particu- larly mink ranchers, for safety and economic

The presence of thiaminase in fish that are reasons. routinely used raw in rations for animals can Also, scientific researchers at times need to cause a dietary deficiency. The disease in mink consider whether or not an aquatic animal is commonly called Chastek paralysis (Green, involved in their research contains thiaminase. Evans, and Carlson, 1937). Knowledge about For example, in biological research where the presence or absence of thiaminase in aquatic fishes are held in aquaria for feeding studies animals is therefore important to mink ranch- or other research, the presence of thiaminase ers and other animal feeders, scientific re- in the animals being fed to the fish could pos- searchers, commercial fish vendors, and others. sibly cause a vitamin deficiency or other prob- Thiaminase is an enzyme that destroys lems that could impede the research (Wolf, thiamine (vitamin Bi) and, like many enzymes, 1942). its activity is greatly reduced or destroyed up- Many of aquatic organisms have been on heating to moderate temperatures (50°- assayed for thiaminase activity in various lab- 100° C).
