| Summary: |
Study included feeding juvenile grass carp Ctenophartyngodon idella on toxic alga Nostoc
muscurum as solitary and mixture feeding ( toxic alga and clover) as compared with fed on
clover only ( control group ) with three feeding periods ( 24 h, 15 days and 35 days ) to
evaluated toxic effects of these types of food on some blood parameters and activity of some
liver enzymes in blood of C. idella juvenile . Study showed significant decreasing in mean of
red blood corpuscles (RBCs) , white blood corpuscles (WBCs), Haemoglobin (Hb), Packed cell
volume (PCV) and total protein in blood plasma when C. idella juvenile fed on toxic alga and
fed on mixture feeding compared with control group with increasing food periods . Also study
showed highly significant increasing P<0.05 in activity of some liver enzymes represented by
alkaline phosphatase (ALP) , alanine transaminase (ALT) and Aspartate transaminase ( AST) in
all feeding periods when C. idella juvenile fed on toxic alga and mixture feeding compared with
control group with notes reduction in survival percentage and means weight of juvenile after
fed on toxic alga and mixture feeding .
