Özet

This study aims to evaluate the selectivity performance of equipment used in commercial striped venus clam (Chamelea gallina) fishing in the Black Sea. Previous studies have expressed that traditional spiral sieves were insufficient in sieving small individuals in particular and that a significant proportion of individuals smaller than the legal minimum landing size of 17 mm were caught. In this context, 15 valid hauls were conducted using a double-layer vibrating sieve, and selectivity parameters were analyzed in each fishing operation. The average L50 (length with 50% probability of caught) was calculated as 16.99 mm and the selection range (SR) as 1.581 mm. Furthermore, it was determined a remarkably low average wastage rate of 0.85% in the marketed catch. It was determined that small individuals and unwanted materials were effectively sieved and returned to the sea thanks to the high selectivity capacity of the vibrating sieve. These results indicate that vibrating sieves offer significant advantages not only in terms of catch efficiency but also in terms of stock sustainability and environmental impact. Therefore, it is recommended that this system be expanded and legally encouraged in the Black Sea.
