Sorting sieve selectivity experiments were carried out on a hydraulic dredge fishery exploiting the clam, Chamelea gallina (Mollusca: Veneroida, Linneus, 1758). Six sieves (from 20 to 23 mm) were tested. The material collected shows that all sieves capture undersized clams. As it is impossible, with current sorting techniques, to avoid presence of undersized clams, the alternative approach “number per kilogram” has been proposed. The result of the study shows in 220 the allowed number of clams per kilogram.

Abstract
Sorting sieve selectivity experiments were carried out on a hydraulic dredge fishery exploiting the clam, Chamelea gallina (Mollusca: Veneroida, Linneus, 1758). Six sieves (from 20 to 23 mm) were tested. The material collected shows that all sieves capture undersized clams. As it is impossible, with current sorting techniques, to avoid presence of undersized clams, the alternative approach “number per kilogram” has been proposed. The result of the study shows in 220 the allowed number of clams per kilogram.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
