Abstract:

The energy budget of female whitemouth croaker Micropogonias furnieri was investigated in the field in Trinidad, West Indies. Daily ration, determined from the variation in stomach content weight over a 24-h period and an exponential gastric evacuation rate model was 3.45%. Growth efficiency averaged 7.6% and decreased from 18.8% at age one to 2% at age seven. Reproductive effort increased steadily from 5.6% at age one to 6.9% at age seven and averaged 6.4%. Growth efficiency exceeded reproductive effort until age three, after which the reverse occurred following the attainment of sexual maturity.
