Discription
Disclosed is an insect breeding system, including a circulating breeding tank mechanism, a plurality of breeding basins and a hydraulic pushing mechanism mounted to the circulating breeding tank mechanism. The circulating breeding tank mechanism defines a channel which is extended in twisting and turning ways and is used for containing water. The breeding basins are used for containing a feed and larvae to be incubated to become large larvae and are used for being driftably disposed in the channel. The hydraulic pushing mechanism is capable of generating a water flow, for driving the breeding basins to float and move along a length direction of the channel, in the channel. Since a breeding tank body conveys the breeding basins by virtue of the channel, the original hydraulic pushing mechanism may be shared by only expanding other breeding tank bodies and communicating channels of all the breeding tank bodies, so that the equipment cost during breeding scale expansion can be greatly reduced, and the expansion way is rather convenient.
