摘要: This chapter deals with updated larvae management techniques, focusing on feed management. A compound diet was produced, and the reasoning behind this, choice of ingredients, manufacturing process are described here. Stocking, feeding sequences results also given. Co-feeding based successively 1-day-old Artemia salina nauplii (7–35 dph), chironomids (20–49 diets (from 29 dph onwards). For 65-day-old fish raised at a water temperature range 18.5–19°C, high survival rates (89%), average weight 3 g were recorded. Six-month-old weaned weighed three times more (90 vs 35 g) than their naturally fed counterparts.
