摘要	Broodstock rearing is fundamental to produce high-quality offspring for aquaculture. However, reproduction requires large amounts of energy and nutrients, and physiological activities of digestive enzymes determine the absorption of energy and nutrients. However, the interaction between reproduction and digestive physiology is still unclear in sea cucumbers. In this study, we used laboratory experiments and field investigations to assess the variations of digestive physiology and digestive function in the sea cucumber Apostichopus japonicus during reproduction. Unexpectedly, activities of both amylase and trypsin were depressed in adult sea cucumbers during reproduction under both laboratory and field conditions. As a physiological consequence, digestive efficiencies of energy and organic matter decreased significantly during reproduction. Although reproductive output of sea cucumbers varied greatly between laboratory and wild conditions, reproductive effort had no effect on the activities of numerous digestive enzymes. Together, these data indicated that reproductive status induced digestive function decline in A. japonicus. Our study provided very important information about the reproductive biology of sea cucumbers that could be applied to broodstock rearing and conservation of this commercially important species.
