A kind of crab breeding cage

Abstract

The invention discloses a crab breeding cage. The crab breeding cage is characterized by comprising a support (1), at least two layers of connecting rods (2) of a crossed structure are arranged on the support (1), the two ends of each connecting rod (2) are both provided with a cage body (3), a bait feeding plate (4) is arranged on a bottom plate (6) of each cage body (3), and the positions of the bait feeding plates (4) of the cage bodies on each layer of the same column are staggered. By means of the structure, the crab breeding cage has the following advantages that one crab is bred in each cage body which is provided with the independent bait feeding plate, the death rate of the crabs is low, and the crabs can grow well. The cage is of multi-layer design for stereoscopic breeding, the breeding quantity of the crabs is large, the occupied area is small, and soil resources can be saved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a crab breeding cage. Background technique [0002] With the improvement of people's living standards, the annual supply of seafood in our country is constantly increasing, which greatly promotes the development of aquaculture industry. In the prior art, when raising crabs, people usually put many crabs in a large breeding cage or pond to raise them. Because the crabs are easy to fight each other during the shelling period, the mortality rate is high, and each crab has a high mortality rate when feeding bait. Crabs eat different amounts of food, some tend to eat too much while others can't eat, which can easily lead to poor growth of crabs. On the other hand, most crabs are raised horizontally, that is, a cage is placed in a pool of a certain area. The amount of breeding is low, the land occupation is large, and land resources are wasted. Contents of the invention [0003...
