I can think of a few practical applications. For example, the minnow bucket water could be mostly poured out at the parking lot and the bucket refilled after arriving at the fishing spot, which of course would reduce the load one had to carry/drag. Also, fish that are caught could be put in a bucket of water instead of freezing on the ice. We all know that thawing and then refreezing fish adversely affects taste and texture. Also, fish could be bled and the bloody water could be pumped back down the hole without staining the ice, which would be a dead give away of one's spot. The pump would need to be small enough to put inside the bibs in the case of very cold weather so it wouldn't freeze between uses. Anybody know of a small pump that could perform these applications?
