Food uptakes and enzyme activities when the Siberian sturgeon, Acipenser baeri (Brandt, 1869), feeds continuously or limitedly

Total feeding rates and digestion effectiveness of the Siberian sturgeon were determined for a limited one-hour feeding and for continuous feeding. The mean fork length was 13.7 1.7 (S.D) and mean weight was 12.0 3.2 (S.D) g for the individuals used in these experiments. Continuous feeding induced s...

The highest trypsin activity showed 4 hours post feeding in both feeding groups. However, the level of activity in limited feeding, either mg unit digestive track or total dried weight of digestive track, was higher in the continuous feeding group. 2008 Conference or Workshop Item NonPeerReviewed application/pdf en http://irep.iium.edu.my/38544/1/WAS_2088-MM_Rahman.pdf Kim , Su-Kyoung and Chul, Ho Lee and Chae, Sung Lee and Young, Dae Kim and Qtae, Jo and Rahman, Mohammad Mustafizur and Rosenthal, Harald (2008) Food uptakes and enzyme activities when the Siberian sturgeon, Acipenser baeri (Brandt, 1869), feeds continuously or limitedly.
