Device for catching oyster borers of breeding plots of oysters and mussels

摘要

EXTRACTION Device (1) for removing oyster borers from a breeding parcel, comprising a catch tray (2) which is moved over the breeding parcel (4). The catch tray comprises a bottom plate (6), side plates (7), a back plate (8) and at the top partly a top plate (9) and partly a trudge system (10), the bars (10) of which extend from the bottom plate to over the top plate. The distance between the bars is smaller than the size of the oysters (12) and larger than the size of the oyster borers (13), whereby the snails end up in the catch tray between the bars, but the oysters do not. The back plate can be opened after the device has been lifted out of the water to be able to empty the catch tray. The oyster borers can then be killed by cooking them. The cooked oyster borers can then, if desired, be deposited on a breeding parcel, where they serve as a breeding ground for a new oyster seed seed. 20 (FIG. 1b) 1042433
