Abstract: The present study was done to clarify whether dietary hydroxyproline (Hyp) was effective for improvement of collagen contents of the fillet in tiger puffer (Takifugu rubripes). We investigated collagen contents in the cranial, middle and caudal parts of the fillet in Experiment 1. The caudal part of the fillet had a high level of collagen compared with other two parts. In Experiment 2, effects of dietary Hyp (1%) on the performance and collagen contents of the fillet were determined at 37 and 81 days of feeding. Growth and feed efficiency was comparable between the control and Hyp groups over the experimental period. Collagen contents were decreased with growth in the control group, but dietary Hyp prevented the reduction in collagen contents in the fillet.
