Abstract EN
The fisheries and stock assessment of shilig Leuciscus vorax (Aspius vorax) the in East Hammar marsh, which is the first study to assess this species in southern Iraq.
A total of 5751 specimens was collected by several fishing gears for a period of January in 2009 until May in 2010.
Total lengths of L.
vorax were ranged from 3.7 to 55.6 cm was as total length.
The species constituted 6.4% from the total catch by seine net and the catch rate ranged from 0.84 kg/hr in May 2009 to 3.33 kg/hr in January 2010 and rate 2.01 kg/hr.
The length-weight relationship obtained was W= 0.0068 x L3.0425.
The fish stock was assessed by lengths, frequency technique using FiSAT program.
Growth, mortality parameters and exploitation rate estimated were: L∞= 65.1 cm, K= 0.22, Z= 0.96, M= 0.5, F= 0.46, E= 0.48, E0.1= 0.411 and Emax= 0.52.
Recruitment pattern of the species exhibited single pulse modal contributed 45% of the total recruits for the period April-September with a peak during June-August.
The mature individuals of L.
vorax were exposed to fishing before the spawning season in Eastern Al-Hammar marsh, because the value Lc (18.3 cm) is lower than Lm (21.5 cm).
Therefore, this study suggests increasing the mesh size and regulating the fishing effort.
