دراسة مقارنة بين طول ووزن سمكتي الخشني (Liza abu) والحمري( Barbus luteus) وبعض مكونات الغلاصم

Abstract

Tow hundered fish (100 fishs of each species )Liza abu and Barbus luteus were included in this study based on the length and body weight .After extraction of the gill,gills weight, length of gills arch ,length of gills filaments and their number and the number of gills rakers were determined .Results could be summarized as fellow :•There was positive correlation between fish length ,their weight, weight of gills, length of gills arch and rackers number of Liza abu and Barbus luteus was found.•Positive correlation between fishs length and number of filament of gills arch of Liza abu the length of filaments of gills arch of Barbus luteus was found.•The presence of positive correlation between fishs weight and gills weight , the length of gills arch and gills rakers of Liza abu and Barbus luteus.•Positive correlation between fishs weights and length of filament of gills arch and their number of Barbus luteus fish was found .•Positive correlation between gills weights and length of gills arch ,filaments length ,the number of filaments and rakers of Liza abu.•Positive correlation between gills weight ,the length of gills arch ,filament length and number of barbus luteus was found.•Negative correlation between gills weight ,the number of rackers of Barbus luteus fishs was found.•Linear regression of som components of gills was calculated based on length or weight of fish or gills obtained results were as fellow.1- Length of Significant effect (p<0.05) of fishs length on fishs weight ,gills weights, the length of gills arch ,number of rakers of Liza abu and Barbus luteus fishs,filament number of gills arch of liza abu and filaments length of gill arch of Barbus luteus .fishs was found.2-Presence of significant effect (p<0.05) of fishs weight on gill weight ,length of gills arch,the number of rakers of Liza abu and Barbus luteus fishs ,and the length and number of filaments of gill arch of Barbus luteus fishs .3-Existence of significant influence (p<0.05) of gills weight on the length of gill arch ,number their filaments and rakers of Liza abu and Barbus luteus fishs, and he length of filamentents of gills arch of Barbus luteus fish .When ther results were statistically analyzed it was found that barbus luteus fish wase superior (p<0.05) in terms of gill weghts , length of filaments of gills arch ,their number on that of liza abu fish where as Liza abu fish was superior (p<0.05) interms of the number of the rakers of gills arch.
