不同饵料种类、投喂方式及环境条件对凡纳滨对虾相对摄食量的影响
Effect of different foods, feeding patterns, and environmental conditions on the relative food consumption ofLitopenaeus vannamei
摘要
Abstract
In this study, to improve the utilization rate of bait and reduce the aquaculture sewage discharge in prawn culture, we examined the effects of food sources, feeding patterns, body weight, aeration quantity, light intensity, water temperature, and salinity on the relative food consumption (RFC) of white shrimp (Litopenaeus vannamei). The results showed that the RFC of shrimp fed with compound feed was higher than that of chilled shrimp. The use of grain-by-grain feeding patterns can significantly enhance the RFC of shrimp. The RFC significantly decreased as body weight increased (P < 0.01). At the same time, the average RFC was lower when shrimp of different sizes were competing for food. The RFC at 6 L/min was significantly greater than at 0 L/min and 3 L/min. The shrimp under weak light achieved a higher RFC. Temperature and salinity had significant effects on the RFC of shrimp (P < 0.01). The highest RFC occurred in the 32℃ group. The minimum RFC of shrimp occurred at 5℃; however, no significant difference (P > 0.05) was found in groups at 15, 25, and 35℃. Therefore, strategies to increase feed-ing frequency in prawn culture should be considered and to adjust feeding amounts by changing the environmental conditions can be reasonably achieved.关键词
