This study aimed to determine the current status, density, and
morphometric characteristics of Crassostrea
gigas in fishermen's shelters in Rize province, located on the eastern
coast of the Black Sea. Sampling was carried out at five stations between 20–26
June 2025, and a total of 146 individuals were evaluated. Length, width, and
weight were measured, and length-weight and width-weight relationships were
calculated. The regression analyses yielded R²=0.8364 for the length-weight
relationship, and R²=0.8509 for the width-weight relationship. Density was also
calculated using 40×40 cm square sampling plots at each station, and the
average individual density was determined to be 182.5 ind./m². Higher densities
were observed at south-facing stations, suggesting that the orientation factor
may have an effect on settlement. The findings indicate that C. gigas is rapidly spreading along the
Rize coast and may have potential impacts on the local ecosystem. In this
context, regular monitoring studies and invasive species management strategies
are recommended.
