Effects of Dietary Herbs on Growth and Body Composition of Juvenile Abalone, Haliotis discus hannai

Three feeding experiments were conducted to investigate the effects of herbs (Obosan-C or Obosan-O) as an additive in formulated diets on growth and body composition of juvenile abalone (Haliotis discus hannai), Three replicate groups of abalone initially average weighing 206 mg, 827 mg and 432 mg were fed the each one of experimental diet containing Obosan for 10 (experiment 1), 7 (experiment 2) and 19 weeks (experiment 3), respectively. In addition, an imported commercial diet for abalone was also employed to compare growth performance of juvenile abalone. Weight gain of abalone fed the diet containing Obosan-O was significantly (P0.05), whereas crude lipid content of abalone fed the diets containing Obosan-C was significantly (P
