2006

This study aims at evaluating the current status of H. tuberculata stocks in exploited areas of western Sicily. The density of the green ormer was slightly greater in unexploited areas although differences between harvested and not harvested areas was not statistically significant. Moreover, analyses showed that length frequencies varied between harvested and not harvested areas.
