A comparative study estimation of percentage of muscles Acanthopagrus latus (Houttuyn , 1782) and Liza subviridis (Valenciennes , 1836) fishes in Karbala province .

Abstract

The present study deals with estimation of percentage of red and white muscles fibers of two species of Teleost , which belongs to two different families she Acanthopagrus latus (Houttuyn , 1782) which belongs to family Clupeidae and Liza subviridis (Valenciennes , 1836) which belongs to family Cyprinidae , The collection study sampling from AL-Hindia River in holy Karbala province by use Gill nets and Cost nets , The appear study Results has differ clear in ranges values to the study length groups , The present study shows the percentage of red muscles fibers were fewer than the white muscle fibers on different body regions (R1,R2,R3) among species . The proportion of red muscle fibers values ranged between (1.15 – 6.34 %) while were the proportions of white muscle fibers ranged between (98.95 – 92.18 %) in studied fish , and showed increase the proportions of red muscle fibers towards (caudal peduncle) posterior region of fish body because important role in fishes swimming and movement . Therefore, Acanthopagrus latus and Liza subviridis fishes put in Sprinters fishes depend on the proportion of White muscle fibers in muscular system in fish body , Therefore consider this study first locally .
