Monitoring of Monthly Price Changes of Cultured Fishes in Sinop Province Between 2012 and 2013

Abstract

The aim of this study was to determine the monthly price changes of cultured fish which were offered for sale in retail fish outlets in Sinop, Turkey. The fish enterprises were determined by stratified sampling method. The enterprises were grouped as I (the most), II (moderate) and III (the least) according to the amount of their sales. Each group was represented by two different fish enterprises. During the study, prices of the same fish species were obtained twice a month at the same time of the day and the data were calculated as average ± SD. The differences between the groups were determined by one-way variance analysis (ANOVA) and the price relation level between species was evaluated by the correlation analysis using IBM SPSS 21 Statisticssoftware. It was determined that sea bream (Sparus aurata), sea bass (Dicentrarhus labrax), rainbow trout (Oncorhyncus mykiss) (portion size and kilos) and salmon (Salmo salar) (import) were offered for sale in fish markets as cultured fish species. These species were sold during the fishing ban period (April-August). They were also sold starting from September when the fishing ban period ended up and the fishery products were at their lowest. For all the species, the differences between the pricesice were not significant between the sampled enterprises. The average values of the current prices were higher than that of 2008-2013 period. A negative strong relation was determined between the rainbow trout and the salmon.
