Some biological aspect of carasobarbus luteus (Heckel, 1843) in hoor al-azim wetland
Journal Title: Scientific Journal of Biological Sciences - Year 2014, Vol 3, Issue 3
Abstract
The Population Dynamics and status of Hemeri (Carasobarbus luteus) in Hoor Al-azim wetland (Khuzestan provinces, Iran) were investigated to derive information required for their management. During this study from 2011 to 2012more than 460 specimens C. lutus were measured. Mean±S.D length Values for this species were 228±15 respectively and maximum and minimum total length were 118 mm and 362 mm respectively. Mean ±S.D weight Values for this species were 190±91gr and maximum and minimum weight were 86- 416 gr respectively. The length-weight relation were calculated as Y=0.0018L3.18 (n=466, R2 =0.96) for total fishes, growth pattern is isometric (P>0.05). The mean Values of condition factor (K) were 1.38± 0.07 in male specimens and 1.43± 0.11 for female specimens. The highest values of K were observed in April and the lowest in October were observed. The mean size at first sexual maturity (Lm) was 210 mm for total fish, and maturity stages indicated that spawning time were occurred during April to July.
