Abstract

The present study deals with estimation of gill surface area to :Burbus luteus the collection studysampling from AL-Hindia River by use Gill nets and Cost nets ,the appear study Results hasdifferent clear in ranges values to the study length groups ,they have small length groups smallabsolute gill area compare large length groups the have groups large absoluts gill area the rangesvalues (1729.12-4078.75 mm2),is was total length average of gill filament the effect on the increasevalues absolute gill area while don’t appear the two other factor (number of secondary lamellae andsecondary lamellae area)the proved study fishes include in the Sluggish Fishes or Slow Swimmingthis study proved first from species on Burbus luteus
