Abstract

• The impact of experimental dredging was assessed on the venus clam Chamelea gallina from seabeds o¡ the Lagoon of Venice. Commercial-sized clams were collected using high water pressure and mechanical sorting (HP), as in professional ¢shing, and low water pressure without sorting (LP). To highlight the e¡ects of acute stress due to the di¡erent approaches in harvesting clams, various biological responses were evaluated at both organism and cell level. Filtration and respiration rates showed opposite behaviour, the former signi¢cantly decreasing, the latter increasing, when mechanical stress was higher. Consequently, lower values of scope for growth in HP clams were observed. The survival in air test exhibited signi¢cantly lower median survival time values (LT50) in more severely stressed animals. The haematocrit value and phagocytic index signi¢cantly decreased in HP samples, revealing a detrimental e¡ect on mechanisms of immunological defence. Acid phosphatase and b-glucuronidase activity was also a¡ected by increasing mechanical stress, even though an opposite trend was shown in the two investigated enzymes. Lastly, higher damage levels were detected in shells of HP clams. (literal)
