Description

Technical Field

[0001] The utility model relates to the technical field of ship structures, in particular to a breeding ship. Background Art

[0002] Compared with animal husbandry and freshwater aquaculture, offshore aquaculture does not directly occupy land resources, but also can ease the pressure on food and livestock supply. Therefore, offshore aquaculture is an important way to get food from the ocean. Aquaculture vessels can cruise to distant waters and independently select aquaculture areas. They are the main equipment for offshore aquaculture. At present, aquaculture vessels mostly adopt closed structures or open structures. When a closed structure is adopted, a water pump is required to replace the water in the aquaculture cabin, which increases the aquaculture cost. When an open structure is adopted, the seawater and the aquaculture cabin are always connected, and there is no need to configure a water pump to replace the water in the aquaculture cabin, which reduces the aquaculture cost. However, when there are strong winds and waves in the sea area where the aquaculture vessel is located, it will impact the aquaculture cabin, causing the fish in the aquaculture cabin to collide violently with the fishing nets or steel nets around the aquaculture cabin, reducing the survival rate of the fish in the aquaculture cabin. Utility Model Content

[0003] The technical problem to be solved by the utility model is: at present, closed aquaculture vessels need to use water pumps to replace the water in the aquaculture cabin, which has a high aquaculture cost; when the open aquaculture cabin is hit by large wind and waves, the survival rate of the fish in the aquaculture cabin will be reduced.
