Interpretive Summary: Two feeding experiments were conducted to determine the maximum bitter phytochemical concentrations (glucosinolates and sinapine, an amino compound found in carinata) from cold-pressed carinata meal that could be tolerated by hybrid striped bass diets. Dietary concentrations of carinata meals below 10% did not reduce feed consumption, utilization and growth while dietary concentrations of carinata above 20% did reduce feed consumption, utilization and growth.

Technical Abstract: Two feeding experiments were conducted to determine the maximum glucosinolate (GLS) and sinapine concentrations from cold-pressed carinata Brassica carinata meal (CPCM) containing 61.2 µmoles of GLS and 6.07 mg of sinapine g^-1^ of meal that could be tolerated by hybrid striped bass Morone chrysops X M. saxatilis diets. Diets in experiment 1 were formulated to provide =5.0 µmoles of GLS g^-1^ of feed ingredients by including =8.16% of CPCM in diets. Analyzed GLS and sinapine concentrations in diets were =2.71 µmoles and =0.181mg g^-1^, respectively. Dietary GLS breakdown products were undetected. These dietary concentrations of GLS and sinapine did not reduce feed consumption, utilization and growth, resulting in similar concentrations of thyroxines and consequently no effect on deiodinase enzymes. In experiment 2, diets were formulated to provide 0, 6.12, 12.24 and 18.36 µmoles of GLS g^-1^ of feed ingredients by including 0, 10, 20 and 30% of CPCM in diets, respectively. Dietary GLS concentrations were 0, 2.65, 5.58 and 9.52 µmoles of GLS g^-1^, respectively. Sinapine concentrations were 0, 0.31, 0.54 and 0.75 mg g^-1^ of diet, respectively. Dietary concentrations of GLS =5.58 µmoles of GLS and =0.54 mg g^-1^ of sinapine reduced feed consumption, utilization and growth.
