Abstract :

Abstract                In annual and seasonal variations, the density of phytoplankton in Golestan Dam was observed in July with the highest density and the lowest density was observed in March. The ability to produce fish is Golestan Lake (203.49 kg/ha) and compared to Khandaghlo Lake (Abdolmaleki, 1393) Which is based on various models with a production range of 167 to 324 kg ha-1, and is almost identical to Lake Shahid Kazemi Dam (Asarab Consulting Engineers, 2011), which is estimated at 290 kg ha-1. By comparing the estimated fish production potential of the lake (203.49 kg ha-1) with the catch per hectare of the lake (142.9), it can be concluded that the production power models used in the total have a good estimation of the actual production capacity of the lake.
