چکیده انگلیسی
⺠Trophic webs of two estuaries were analysed with stable carbon and nitrogen isotopes. ⺠Ultimate organic matter sources supporting production of fish species were determined. ⺠Main prey of fish used mostly salt marsh-derived organic matter as nutritional source. ⺠Fish species trophic levels differed at inter-species level, seasonally and spatially. ⺠Organic matter is transferred to higher trophic positions through benthic pathways.
