Abstract: (4794 Views)
The estimation of fish potential production and trophic status are two important and necessary parts of fisheries management in lakes. This study was conducted to determinate the trophic status and fish production potential of Golbolagh Lake, for one year from October 2013 to September 2014. Physicochemical parameters and other necessary data such as chlorophyll a, phytoplankton phylum dominance and macrobenthos biomass were used to estimate the fish potential production and trophic status of Golbolagh Lake. Trophy State models of Carlson, total nitrogen model of Kratzer and Brezonik and table of Li and Mathias were used to determine trophic status of Golbolagh Lake.The fish potential production of Golbolagh Lake were estimated using Ryder (MEI) model, Janjua, De Silva and Funge-Smith, Li and Mathias and Dawning et al. models.
The results showed that Golbolagh Lake is a eutrophic to hypertrophic lake and annual average of fish productivity was estimated 138.42±72/13 (Kg/ha). Owing to high trophic status of Golbolagh Lake, fish production was expected to be greater. However, due to low density of phytoplankton, production was medium.
