Determination of feeding Benni ( Barbus sharpyie) First phase: Hole body analysis and som biological characteristics

In order to determination of feeding requierments, in first step hole bady analysis and some biological characteriestis of Barbus sharpyie was investigated in khouzestan provience in 2001-2004. In this study 413 benni (Barbus sharpyie) in length size range (30 to 440 mm) were caught from different resources in region (mainly Shadegan and Horalazim wet lands) Fishes were classified in different length groups for carcasse analysis, The highest protein was observed in (30 to 95 mm) and (100-140 mm) length size groups, and also the rate of protein decrease with Length increase The lowest lipid (body fat) rate was observed in (100-149 mm) length size group and also with decreasing the protein in length groups, lipid was increased in Benni (Barbus sharpeyi) body. The maximum rate of body ash was measured in (30-95 mm) length size group, after this with increasing of the length, the rate of ash decreased gradually, so the minimum ash rate was observed in (30-440 mm) length zise group. Phas phorous and calcium variations were the same as ash changing the maximum energy was obtained in (250-350 mm). That was in harmony with increasing in this length groupe. Falty acids in Benni bady were higher then X-3 and were similar to falty acids profiles in carp fishes bady Benniprotain in cludes Essential amino acids, Arginine, Histidine, Iucine, Methionine, Valine, Phenylalanine, theronine, Lysine, that were the same in different individual. ٥٧ Regarding length weight relation. Benni growth is Allometric and regarding stomach contents and increasing of gutlength Index in different length size groups, its feeding habits is herbivorous . Key word: Benni (Barbus shapeyi- body analysis- Biological feeding – shadegan wetlands- horoalazim wetalnds).
