Research paper


Monthly samples were collected from five stations of Shadegan Wetland: Doragh, Rogabe, Khorosy, Salmane and Atish. During this project, 526 fishes were measured from April 2014 to March 2015. Mean ± SD length values for the male and female were calculated as 164 ± 35 (123–264), 198 ± 40 (106–322) respectively and mean ± SD weight values were 81 ± 68 (23–308), 148 ± 96 (18–650) g, respectively. The length–weight relation was calculated as Y= 0.000008L3.13 (R2 = 0.96) for male, Y= 0.000009L3.15 (R2 = 0.93) for female, and length and weight relationship was significant at the level of 0.05. The time of spawning was determined from April to November, and length at maturity (LM), weight at maturity (WM) and production per biomass (P/B) were calculated for total fish as below LM = 163 mm; WM = 37 g and P/B = 0.74, respectively. L, K, t0 were estimated to be 346 mm, 0.36 per year, and − 0.23, respectively. Natural mortality, fishing, total, and exploitation coefficients were 0.75, 0.77, 1.52, and 0.51, respectively.

Article Highlights

  • Data can be used for improved fish management for this wetland.

  • Values are useful for fishery biologists to determine the estimation of fish production in different ecosystems.

  • Differences in the length–weight relationship can be due to seasonal fluctuations with environmental parameters.
