CULTIVATION DEVICE OF INDIVIDUAL OYSTER WITH ROPE-HANGER TYPE

摘要

The present invention relates to a cultivation device used in individual oyster cultivation and, more specifically, to a rope-hanger type individual oyster cultivation device. According to the present invention, multiple breeding chambers for individual oyster accommodation are disposed to be stacked in multiple stages between an upper plate cover and a lower plate support stand using assembly bolts in a device main body and the device main body is allowed to be cast underwater so that the device main body including the breeding chambers can be easily placed to a water depth level suitable for individual oyster breeding. The optimal breeding environment significantly increases high-quality individual oyster harvest. Also, the rope is used instead of an external case such as a wire mesh cage of the related art as a breeding chamber holder while the multi-stage stacking structure of the breeding chambers themselves using the assembly bolts is applied, and thus the cultivation device can be easily manufactured and installed and can be competitive in terms of costs and expenses. In addition, heterogeneous life and foreign matter attachment is suppressed to a minimum, and thus the costs required for cultivation device repair and maintenance can be saved, and a quantity of the oysters can be safely cultivated per unit area. Even the single cultivation device allows oysters with different sizes, ranging from spats to mature oysters, to be produced at the same time so that utility of individual oyster breeding can be maximized, high-quality oysters can be manufactured economically, and incomes and exports of fishing households can be increased.
