Exploring the Antifouling Potential of Sabellaria Simplex Crude Extract: A Promising Solution for Biofouling Management

This study investigated the effects of different concentrations of an extract on cyprid mortality and settlement behavior.Extract concentrations of 6 mg/ml, 8 mg/ml, 10 mg/ml, and 12 mg/ml were tested on 100 cyprids each.Results revealed a dosedependent relationship, with higher extract concentrations leading to increased mortality and reduced settlement rates.At 6 mg/ml, cyprid mortality was 70%, decreasing to 30% at 12 mg/ml.higher concentrations also showed stronger inhibitory effects on settlement, with only 33% settlement observed at 12 mg/ml.These findings suggest the extract's potential as a befouling control agent, warranting further research for practical applications in marine ecology.
