Abstract: The present invention relates to a breeding system for the breeding of crawling insects, comprising a drum, a shuffling device and a feeding device. The drum comprises at least one wall, defining a drum interior, to house the insects, and the shuffling device is arranged at least partially in the drum interior, to shuffle the insects. The feeding device id configured to feed nutrients into the drum interior. The system comprises a cooling device having a cooling fluid circuit that is, by means of a flow of coolant in the circuit, configured to withdraw heat from the drum interior. The invention further relates to a protein production system, for the on-site production of protein-rich insect larvae as animal feed, and to a method for the breeding of crawling insects, comprising the step of cooling the insects in the interior of the drum with a cooling device.

Abstract: In a situation where animals, such as beavers, attempt to flood lands by blocking culverts or constructing dams across waterways, a device is used to maintain a constant flow of water through the dam or culvert. An elongated pipe or culvert with a downwardly directed opening distant from the culvert or dam is used. On the end of the pipe closest to the culvert is a gate which prevents animals and debris from passing through but allows for the smaller elongated pipe to communicate with the culvert. The beaver instinctively attempts to dam the gate area rather than dam the underwater opening of the elongated pipe, and thus is unsuccessful in stopping the flow of water.
