The study aims to investigate the monthly changes in the prices of culture fish that were sold in retail fish outlets in Sinop in 2019 and determine the correlations between the prices of the species. The retail outlets were determined using stratified sampling and divided into three groups as I (high). II (medium). and III (low) with respect to their product range and sale amounts. https://allfixelectricales.shop/product-category/rocker-switch/
