Only gastropod abundance and the abundance of the polychaete families Pectinariidae and Sabellidae showed persistent negative effects of fishing.
The analysis of polychaete family abundance during the study period showed that the families Pectinariidae and Sabellidae (mainly comprising tube building, sedentary, and suspension-feeding species) were significantly, and persistently, affected by fishing (Table 1).
A detailed analysis of polychaetes families showed that families Pectinariidae and Sabellidae, mainly comprising species with suspension feeding modes (besides being sedentary) were persistently affected by fishing, which could at least partially support the result found for that ratio.
