Abstract

The invention provides a floating net cage used for cultivating individual seed oysters in an outdoor soil pond. The floating net cage used for cultivating the individual seed oysters in the outdoor soil pond comprises a frame formed by welding steel bars, a screen surrounds the bottom and the periphery of the frame, a floating ball is arranged on the top of the frame, and a weight for weighing down is arranged on the bottom of the frame. According to the floating net cage used for cultivating the individual seed oysters in the outdoor soil pond, the individual seed oysters can be directly arranged on the net cage, the individual seed oysters can be cultivated in a large scale by taking full advantages of water body of the outdoor soil pond, the individual seed oysters are high in growth speed, high in survival rate and convenient to manage, operation is easy to carry out, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of fishery production tools, in particular to a floating net cage for cultivating individual oyster seedlings in outdoor earthen ponds. Background technique [0002] Individual oysters are oysters that are free and without anchorage. Oysters have the living habit of flocking, and often multiple oysters are fixed together. Due to the limitation of growth space, the shell shape is extremely irregular, which greatly affects the appearance. Clustering also causes oysters to compete for food, affecting their growth rate, resulting in large individual differences and low commercial economic value. The bulky scallop shells, tiles and other attachment bases consume a lot of labor in the handling work; because the oysters are firmly fixed, the oysters must be peeled off one by one when harvesting, which brings inconvenience to the harvest of oysters, which not only affects work efficiency, but also Not conducive to...
