Abstract

In this study, seasonal variation of nutrient composition of chub that sampling survey was carried out between April 2013-March 2014 (Squalius sp.) at Çiftekavak stream in Rize, Turkey was investigated. It was used chub fishes whose mean of total length 16.68±1.65 cm and mean weight 68.33±29.49 g. pH, water activity (aw), colour, crude ash, crude protein, crude fat analysis was examine to determine of variation of nutrient composition. Winter, summer, spring, autumn data was evaluated. Max value of % crude protein was observed in summer as 19.49 %. When looked at the % crude fat data, min value was detected in winter as 2.45 %. In addition of these, there are statically significant variations as seasonal resulted from other analysis.
