Artemia nauplii are adequate initial feeds for the hatchling rearing. H� sanguineus of less than 4 mm body width is also used to feed 10-day-old hatchlings. The
survival rate is 75 % after 1 month of rearing (Fig. 22.7b).
3. A mixed fresh diet such as juvenile crab, shellfish and shrimp becomes the main
feed for juveniles of O� minor. After 6–7 months under indoor culture conditions
(Fig. 22.7c), O� minor bigger than 100 g can be harvested for marketing, or transferred to outdoor ponds to continue the ongrowing process, or released to the sea
for stocking or enhancement programmes.
4. Under indoor culture conditions, the longest period of survival for males is 250
days; the female lives 346 days, with a weight of 117.3 g after spawning.
