متن کاملEffect of urban wastewater on age and growth of Chub Squalius cephalus (Linnaeus, 1758) in the Gheshlagh River, Sanandaj
In order to determine the age and growth of Chub in the Gheshlagh River of Sanandaj, two areas were selected; one in upstream of the river (Naysar; high water quality) and the other in downstream (Soaryan; impaired water quality). A total of 280 fish specimen were caught during four seasons. The overall male to female ratio was 1:1.86 in Naysar and 1:0.61 in Soaryan. Both ratios were significan...
