With regards to the importance of fish and fish products as an important available resources of animal proteins and with attention to their rapid spoilage, it is necessary to open a new window in rapid and economic control of these products. Therefore we have carried out a comparative stuy on 21 samples of bony marine fish used in canneries and market’s sale in Tebran since 1998, with two methods of assessing their quality control i.e macro kjeldal determination of total volatile nitrogen (TVN) and aerobic toal count (T.C). Considering the standard level of T.C and TVN i.e 7-lOg and 30 mg/100 g of fish respectively and according to Fisher’s exact test, there was no significant difference between two factors which were examined (P=0.27l4).
