DO LOW PRICE FISH, HAVE HIGH NUTRITIONAL VALUE?

摘要

The aim of this paper was to compare the nutritional value of some low price fish {Sardina pilchardus, Engraulis encrasicholus, Anguilla anguilla, Salmo trutta, Mugil chepalus) to high price fish with high consumption rate {Sparus aurata, Merluccius merluccius, Dicentrarchus labrax).In general, the commercial values of several fish species in Greece was not always related with the nutritional value (proteins, lipids and polyunsaturated fatty acids). Despite the price differences, total lipid contentis higher in eel {Anguilla anguilla) and grey mullet {Mugil chephalus), compared to other species. Moreover, concerning unsaturated fatty acid content, there are significant differences in favour of grey mullet and sardine {Sardina pilchardus). Differences in favour of eel are also reported for cholesterol, as well as differences in energy content in favour of eel and grey mullet. Absorption index for all species was higher than 0.92. In conclusion, fish with very low price seem to have the same or higher nutritional and energy value, compared to highly priced fish.
