Studies on the nutrition of marine flatfish. The thiamin requirement of turbot ( Scophthalmus maximus )
1. Seven groups of young turbot ( Scophthalmus maximus ) were given diets containing graded levels of thiamin (0.19–50 mg/kg) for 16 weeks and their growth rate was measured during this period. 2. Good growth was obtained on all these treatments except in the group given the lowest dietary thiamin l...

1. Seven groups of young turbot ( Scophthalmus maximus ) were given diets containing graded levels of thiamin (0.19–50 mg/kg) for 16 weeks and their growth rate was measured during this period. 2. Good growth was obtained on all these treatments except in the group given the lowest dietary thiamin level (0.19 mg/kg). These fish grew normally until the 12th week but thereafter their weight did not increase. 3.
