Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0028] like Figure 1-3 , a multi-independent space shielding device for portunus trituberculatus cultivation, is characterized in that it includes three sets of tubular shelters, each set of tubular shelters includes one shielding tube each of three tubular types: large, medium and small, and three sets of tubular shelters. The shielding tubes are connected sequentially in the order of large, medium and small, and the inside is connected and both ends are open;

[0029] The large tubular shielding pipe 1 and the medium tubular shielding pipe 2 are connected by a large annular connecting plate 8, and the medium tubular shielding pipe 2 and the small tubular shielding pipe 3 are connected by a small annular connecting plate 9;

[0030] Three groups of tubular shielding tubes are arranged side by side, and two adjacent large tubular shie...

Abstract

The invention discloses a multi-independent-space shielding device for breeding portunus trituberculatus. The multi-independent-space shielding device for breeding the portunus trituberculatus comprises three groups of tubular shields, large rectangular shielding plates, small rectangular shielding plates, supporting plates and the like, wherein each group of tubular shields comprises a large tubular shielding pipe, a medium tubular shielding pipe and a small tubular shielding pipe, the three shielding pipes are sequentially connected in the sequence of large, medium and small, the interiors of the three shielding pipes communicate with one another, and the two ends of each shielding pipe are open; the three groups of tubular shielding pipes are arranged side by side, every two adjacent large tubular shielding pipes adhere to each other, every two adjacent medium tubular shielding pipes are connected through the horizontally-arranged small rectangular shielding plates, and every two adjacent small tubular shielding pipes are connected through the horizontally-arranged large rectangular shielding plates. Compared with a traditional plastic basket shielding pipe, the utilization efficiency of the bottom of a pond and the protection effect on crabs are greatly improved, more independent spaces can be provided, and juvenile crabs and crabs in the molting period can be effectively protected.

Description

technical field [0001] The invention relates to a multi-independent space shielding device for Portunus trituberculatus cultivation, which belongs to the technical field of aquaculture. Background technique [0002] Portunus trituberculatus is an important aquaculture species in my country, and it is widely cultivated in Shandong, Jiangsu, Hebei and other provinces of China. In recent years, with the improvement of pond culture technology, the low survival rate caused by the fighting of cannibalism has become a bottleneck restricting the development of the industry. When Portunus trituberculatus is in the juvenile stage, battles and cannibalism occur very frequently, and the mortality rate is the highest at this stage; in addition, Portunus trituberculatus has a soft body, weak vitality, and the shell has not yet calcified, and has no defense against the aggressive behavior of other individuals. Ability, easily cannibalized by other individuals. Visual isolation and indivi...
