الملخص EN

The current study included anatomical study to compare some specific criteriafor food activity in two types of inequality are feeding fish, shank (Acanthopagruslatus), Which inhabits saline water environments and (Barbus luteus) which inhabitsthe fresh water environment, have been studying the filtration area diet for eachtype1The results of the current study showed some variation in gill parameter includethe ( Length of gill arch, the number of the gill arch teeth, the thickness of the baseof the gill richer) that resulted in significantly different at (p≤0.05) in filtration areaand filtration space when comparing the two types with the noted that the moralwas in favor of shank fish (Acanthopagrus latus) for the food filtration area, whilethe morale in favor of the fish Barbus luteus for the filtration space in addition tothe possession of Barbus luteus five gill arch carrying gill richer on the sides of thedorsal and abdominal except the fifth arch, which has a single row of gill richerabdominal while the Acanthopagrus latus have four gill arches carrying two rowsof gill richer which had a long conical shape and had a wide base and a thin end inthe Acanthopagrus latus while it was short and cylindrical and pointed end and abroad base in the Barbus luteus seems to be in line with the nature of the differentfeeding in two kind fish.
