| Abstract | ||
| The feeding behavior experiments showed that the feeding of juveniles Macrobrachium nipponense are mostly and frequently occurred on the artificially net covered walls of the experimental tanks, this finding were observed in all the three tested bottom types (net covered wall (A), water column (B) and bottom (C); smooth or sand-clay bottom), and during the two tested feeding times (after 2 hr and 24 hr of experiments onset, and in both smooth and sand-clay tanks bottom. The estimated ratios were 80%, 9%, 11% and 73%, 12%, 14% at the (2 hour) period in smooth and sand-clay bottoms respectively, but during (24 hour) period were 72%, 12%, 16% and 67%, 12%, 21% at tanks of a smooth and sand-clay bottom respectively. As a conclusion of the observed results this prawn seems to be a pelagic feeding species. | ||
