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