Abstract
Feeding, growth and survival of hatchery-bred juvenile abalone, Haliotis asinina (mean initial shell lengths: 32 mm) stocked at 25, 50 and 100 m-2 of shelter surface area in mesh cages suspended in indoor tanks were determined. Animals were fed the seaweed, Gracilariopsis bailinae, to excess given at weekly intervals. After 250 d, avereage daily growth rate (mean: 122 µm d-1 shell length, 156 mg d-1 body weight) was highest in abalone reared at the lowest stocking density (25 m-2 ). Abalone stocked at 50 and 100 m-2 had similar growth rates that ranged from 96 to 98 µm d-1 SL and 123 to 131 mg d-1 BW). Daily feeding rates of 29 and 30% were not significantly different for abalone stocked at 25 and 50 m-2, respectively, but were higher than abalone stocked at 100 m-2. The higher feeding rates of 24-28% day-1 of abalone in all treatments starting day-129 until day-160 could be due to the onset of sexual maturation as most abalone are already mature at this size. Survival rates were generally high (91-98%) and were not significantly different among treatments. However, body size (range: 59.3 mm SL, 57-58.4 g BW) at harvest was bigger in animal stocked at 25 m-2 than those stocked at 100 m-2. Sexual maturation during culture did not hamper growth of abalone. G. bailinae proved to be a sufficient food source for abalone grow-out. A stocking density between 50-100 m-2 is recommended for tank grow-out of H. asinina.
