Effects of Different Cyclic Starvation and Refeeding Regimes on Growth of Hybrid Grouper (Epinephelus fuscoguttatus♀ × E. lanceolatus♂)
摘要
Abstract
Effects of four feeding patterns on feeding and growth of the hybrid grouper,Epinephelus fuscoguttatus (♀) ×Epinephelus lanceolatus(♂), with initial body weight 84.5 ± 12.9 g fed by an artificial feed in fiberglass buckets in indoor were investigated for 30 days. The feeding patterns are as follows: to feed daily, or to starve one day and then feed for one day, or starve one day and then feed for 2 days, or to starve one day and then feed for 3 days, designated as groups of A1, A2, A3, and A4, respectively. The results showed that the growth rate of body length (GBL) in the group A1, A4 was higher, 20.68%, 19.42%, respectively, and the differences from the other two groups were statistical (P < 0.05). Group A4 and A1 represented higher growth rate of body weight (GBW), 79.64%, 76.50%, respectively, and the differences from the other two groups were statistical (P < 0.05). There was no statistical difference between group A1 and A4 for both GBL and GBW (P > 0.05). Both the specific growth rate (SGR) and food conversion efficiency (FCE) were higher in group A4 and A1, SGR 1.89%·d-1and 1.95%·d-1, and FCE 1.14 and 1.19, respectively, with no statistical difference between this two groups, but statistically differed from the other groups (P < 0.05). Therefore, the four index of group A1 and A4 were better than the other two groups, but considering the production cost, the optimal feeding pattern for the hybrid groupers culture was to starve one day and feed for 3 days.关键词
