Studies on the decapod fauna of the Turkish sea have been carried out since 1965 and up to date, a total of 228 decapod species were reported from the Turkish coasts (Kocatas et al., 2004). Decapod crustaceans are particularly well adapted for long distance migration and occupation of new localities (Green, 1961). The migrations occurring via Suez and Gibraltar Straits are changing the fauna of the Turkish sea. As a result, the Turkish sea has favored speciation in many decapod species. Eriphia verrucoso is one of those with commercial value in Mediterranean countries. The main objective of this study was to determine the proximate composition and the shelf life of the warty crab Eriphio verrucoso during cold storage. Crabs were collected from nature and the following composition values were determined: moisture 72.24 +/- 0.21%, crude fat 0.88 +/- 0.09%, protein 17.12 +/- 0.40%, ash 2.34 +/- 0.40% and carbohydrates 6.32 +/- 1.02%. A trimethylamine nitrogen (TMA-N) value of 1.55 +/- 0.75 mg N/100 g was determined on the first day of refrigerated storage, indicating good quality. After a storage period of 12 days,TMA-N values of crabs still indicated good quality for consumption, although the crab meat was spoiled according to the total volatile basic nitrogen (TVB-N) content. The TVB-N values of crabs, which were determined for 12 days, showed that crab meat was spoiled on the 12(th) day as values above 35 mg N/100 g were determined, thus exceeding the quality index limits.
