Differences in feeding behavior and intestinal microbiota may relate to different growth rates of sea cucumbers (Apostichopus japonicus)
The sea cucumber Apostichopus japonicus is an economically important species in Asia. Large growth differences have been recorded for A. japonicus during field surveys and culture practices. These growth differences can seriously impact the recovery of wild populations and breeding efficiencies in a...

The sea cucumber Apostichopus japonicus is an economically important species in Asia. Large growth differences have been recorded for A. japonicus during field surveys and culture practices.

The results showed that there was no significant difference in the movement behavior of A. japonicus with different growth rates, but the feeding behavior of slow-growing A. japonicus was significantly reduced. The activity of trypsin, the main digestive enzyme in A. japonicus, was significantly decreased in slow-growing individuals.
